The scene is a Norwich, England, garden, wherein one night a plastic saucer full of tap water was placed. The night was clear, cold, and windless. In the morning, T. Bushnell found protruding from the saucer a "strange tubelike structure" about 3 inches long. His color photograph cannot be conveniently reproduced here, but it clearly shows his icicle growing upward at about a 45 angle. Bushnell wrote further: "What may not be apparent from the picture is that the tube is triangular in cross section and it is completely hollow down as far as the unfrozen water lying underneath the thick layer of ice. The fairly robust tube was an integral part of the underlying ice pool. We noticed that the outside of the tube was segmented in appearance, as though the ice had built up layer by layer." (Bushnell, T.; "Ice Surprise," New Scientist, inside back cover, October 7, 1995) Comment. The other "weird" icicles we have reported were all solid and roughly hexagonal prisms.

"At about 2240 UTC, the observers saw a strange effect in the sea stretching for approximately 100 m from the parallel body. It was a soft white light, almost strobe-like in character that pulsed irregularly. The light was bright enough to illuminate the wheelhouse deckhead and seemed to emanate from below the water, almost as if something was shining a spotlight upwards, shimmering and twirling: psychedelic projections of the 1960s were brought to mind. Curiously, the wash from the bow was not illuminated and appeared normal, likewise the wake." The phenomenon lasted for 6 or 7 minutes, faded, and then reappeared briefly.

A planet-wide dust storm had just subsided, and the theory evolved that both water and carbon-dioxide ice had frozen on dust particles in the atmosphere. Such particles were heavy enough to fall and give the scene around Viking a snow-like coating. However, frost was again photographed in 1979 (one Martian winter later) without the benefit of a dust storm. So, Mars theorists are in a quandary -- no dust, then no frost theory is reasonable.

The largest "nugget" of nearly pure copper comes from Lake Superior and weighs almost 46 tons! But the Corocoro mines are rich in another way; copper "pseudomorphs." In copper pseudomorphs, copper ions insidiously invade crystals of other minerals and assume their shapes. Copper pseudomorphs of aragonite, a form of CaCO3 , are common. Aragonite sometimes occurs as short, tabular, hexagonal prisms, as shown in the sketch. Under the water table, in a copper-rich area, copper ions in solution "attack" aragonite crystals. First, they oust and replace the outer layers of CaCO3 , gilding the aragonite crystal with a thin layer of pure copper. Then, they work inwardly and eventually usurp the whole crystal and take on its shape. Even stranger are those hexagonal crystals that are pure aragonite in the top half and pure copper in the bottom half. Mineralogists speculate that these formed along the edge of the water table.

Such now seems to be a limited view. There is light at the bottom of the ocean! "Of particular interest is the potential for deep-sea vents and subsurface environments to support geothermally (rather than solar-) driven photosynthesis. Recent work on ambient light conditions at hydrothermal vents indicates that the photon flux generated by thermal radiation of 350 C water should be sufficient to sustain lowlevel photosynthesis, and there is at least one report of a faculative phototroph isolated from water samples taken near a deep-sea vent." A particularly important implication of this undersea light source is that the evolution of photosynthesis need not have been dependent upon the existence of life on land. Also, hydrothermal vents could have served as refuges for photosynthesizing life forms down the geological eons when: (1 ) ocean surfaces were ice-covered; (2 ) the terrestrial surface was exposed to deadly levels of radiation, as when the ozone layer was destroyed; and (3 ) when volcanism or dust from meteor impacts blackened the skies.

Well, L. Frank, University of Iowa, did just that in 1986. He was duly pilloried for his trouble. But, at the 1997 spring meeting of the American Geophysical Union, Frank presented new data to back up his previous assertions. The most startling of his new evidence came from a camera aboard a NASA satellite. Time-lapse photos imaged two objects streaking into the atmosphere over Poland and Germany. Frank identified these as clouds of water molecules from disrupted icy minicomets. The clouds had expanded from the house-size minicomets to clouds 3550 miles wide, weighing 20-40 tons. Frank thinks the minicomets come from a cloud of such objects orbiting the sun from earth out to Jupiter and beyond. Why don't they evaporate in the sunlight and near-vacuum of outer space? Perhaps, thought Frank, they are protected by a thin coating of carbon. (Roylance, Frank D.; "Space Snowballs Theory Gains Credence," Baltimore Sun, May 29, 1997.

Sir Alister Hardy suggested this hypothesis in 1960 in an attempt to account for several human characteristics that are unique among primates but common in aquatic mammals. Some of these are: position of fetal hair, loss of body hair, subcutaneous fat, face-to-face copulation, weeping, etc. The combination of hairlessness and subcutaneous fat seems almost totally confined to aquatic mammals and humans. Two other characteristics are covered in some depth in this article: The discovery that some prehistoric shell middens consist of deep-water shellfish, which must be the result of breath-held diving. This human skill, again unique among primates, is obviously quite ancient. Furthermore, recent experiments suggest that in humans, in addition to seals and ducks, vascular constriction is not limited to the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health.

... Example 1. G. Whitesides, at Harvard, has dumped large quantities of millimeter-size iron balls into a plastic dish and then spun a bar magnet under the ensemble with startling results. The balls swarm around inside the plastic dish as the magnet rotates. At first the swarm is disordered. But after a minute, it breaks up into a set of concentric rotating rings. Within each ring, the balls follow one another along precise tracks, as if hugging the rim of an invisible roulette wheel. Soon the balls in each track are perfectly equidistant. Finally, one ball in each ring comes to a dead stop. The other balls in each track line up behind the leader in a tiny arc, even though the magnet is still whirling away below. Example 2. In water, large, fatty molecules (phospholipids) are observed to self-assemble into double layers with their water-loving bonds pointing outwards. This sort of structure closely resembles that of the biological membranes so vital to terrestrial life. This potentially biologically useful structure self-assembles! It seems that on the mesoscopic scale, under certain conditions, ensembles of particles (e .g ., iron balls and large molecules) may snap into "dominant states" that exhibit unexpected properties.

Called "whitings," these clouds of suspended material are not minor phenomena to file away and forget. Some of the bright streaks are 200 square kilometers in area and can be seen from the Space Shuttle. The source of the whitings has not been determined with certainty. The locals claim that schools of fish stir up the fine, white, calcareous sediments. This is doubted because fish are very scarce in the areas where whitings occur. Another thought was that calcium carbonate was being precipitated directly from the ocean water. Chemical tests showed this to be impossible. A new theory has schools of sharks intentionally raising clouds of bottom sediments to blind fish. The sharks then move in with their electrosensitive organs, which are unaffected by the "white-out," and pick off the helpless fish.(Copley, Jon; "Sneak Attack," New Scientist, p. 22, December 2, 2000.)

Archeologists have debated the mound's purpose for decades. Being elevated above the floor of a usually dry canyon as it is, the mound certainly does not seem to be a reservoir, but that is what recent research says it is. The mound is shaped like an inverted frying pan, with a 1500-foot-long handle that leads to a normally dry stream bed higher up in the canyon. The Anasazi were excellent water managers and took advantage of the flash floods that roared down the canyon every few years. To impound some of this valuable water, they initially built a conventional reservoir, but it was soon silted up by the freshets. So, they gradually raised the reservoir walls and constructed a raised canal to the stream bed. It was all very logical. The engineering of the canal is particularly impressive. The channel is 4-8 feet wide, but only 1-2 feet deep. Its steep, 15-foot-high sides are shored up with neatly aligned stones that were carried in from somewhere outside the canyon.

They are not true compounds, but rather clathrates or inclusion compounds. They often form in huge masses in ocean-bottom sediments and, if disturbed by slumping or some other stimulus, can release immense quantities of gas bubbles. These gases rise to the surface, subdivided en route, and reach the surface as a huge upwelling of frothy, low-density fluid. A ship cannot float in such low-density fluids. If a large plume rose above the sea's surface, aircraft passing through it would lose engine power. Quoting the final paragraph: "Intermittent natural gas blowouts from hydrate-associated gas accumulations, therefore, might explain some of the many mysterious disappearances of ships and planes -- particularly in areas where deep-sea sediments contain large amounts of gas in the form of hydrate. This may be the circumstance off the southeast coast of the United States, an area noted for numerous disappearances of ships and aircraft."

While volcanic eruptions form most sea-mounts, these mountains consist of a nonvolcanic rock called serpentinite, and oceanographers are not entirely sure how the serpentinite mountains formed." The theory of plate tectonics has the Pacific plate diving under the Philippine plate along the Mariana trench. It may be that water trapped in the downgoing crust leaks out, rises, and serpentinizes the crust above. This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains.

In the frigid waters ringing the continent of Antarctica live approximately 275 species of fishes, 95 of which are assigned to the suborder Notothenioidei. This particular group of fishes is renowned for its unusual adaptations, as outlined below by D. Policansky: "Some of them have glycoprotein antifreezes in their blood, some have no hemoglobin, some have so small a temperature tolerance that they die at temperatures above 4 C, some are neutrally buoyant despite lacking swim bladders, and some live as deep as 2950 meters.

This is not the case. The visual fields of the hammerhead's eyes do not overlap at all. Each eye presents the brain with a separate, completely different image to integrate. What, then, could be the purpose of the hammer head? No one really knows, but three suggestions are as follows: The head acts as a hydrofoil and gives the heavier-than-water, swimbladderless shark better swimming control. Grooves on the hammer head channel water toward the nostrils, providing "stereoscopic sniffing." The head is a platform for electromagnetic sensors that help locate prey. Stingrays are a favorite food of the hammerhead, and the shark may de-tect them electromagnetically, as surmised by the author of this article in the following encounters: "I have observed great hammerheads swimming close to the bottom, swinging their heads in wide arcs (a motion common, in a lesser degree, to all large sharks) as if using the increased electroreceptive area of their hammer like the sensor plate of a metal detector.

The slow heaving of their surfaces is a poorly understood phenomenon as the following abstract demonstrates. The surfaces of bogs and fens in northeastern Minnesota may rise and fall by as much as 36 cm in a single day. This phenomenon, known as Mooratmung, or bog breathing, has been traditionally attributed to changes in water storage. However, the surface deformations recorded by static GPS [Global Positioning System] stations on bog and fen sites within the Red Lake peatland are more frequent and out of phase with precipitation events. These vertical fluctuations instead appear to be related to a complex interplay among climate, hydrology, and microbial gas-production. Climate-driven re-charge on bogs, for example, stimulates the production of biogenic gases by advecting root exudates deep into the peat profiles. Seasonal droughts, however, favor the formation of transient confining layers that trap biogenic gases into discrete pockets... Bog breathing may therefore be a surface manifestation of the accumulation and release of greenhouse gases in peat deposits. (Glaser, Paul H. et al; "Bog Breathing: the Curious Interplay of Climate, Ground-water, and Greenhouse Gases in Boreal Peatlands," Eos, 80:F47, 1999.)

Back on the Gobi, geologists remarked that the rich fossil deposits were found in structureless sandstone; i.e ., there was none of the cross-bedding seen in sandstones elsewhere in the region. Furthermore, fossils were extremely rare in the cross-bedded sandstones, which were built up over long periods of time. It looked as if the structureless, fossiliferous sandstones were sandslides differing from those in Nebraska in their much greater magnitude. But why were the Gobi sandslides so much larger and, apparently, faster? The next clue came from the recent devastating mudflows in California and Central America caused by heavy rains. These debris flows were made deadly when the infiltrating rainwater was blocked by bedrock. The accumulating water turned the soil into a muddy slurries that raced down hills at high velocities, overtaking animals (including many people) trying to escape. There is no bedrock in the Gobi, but a little digging encountered impervious layers of caliche. The Gobi caliche consists of layers of sandgrains cemented together by calcium carbonate. Typically located 2-3 feet below the dune surfaces, the caliche layers were evidence that the Gobi had experienced benign periods in the past with low winds, stable dunes and more moisture. But when heavy rains doused the Gobi dunes, the water was blocked by these caliche layers. Result: fluidized sand and catastrophic sand slides.

The surveyors discovered extensive post-glacial landscapes suitable for human use now covered by 150 meters (500 feet) of ocean, but which were exposed 10,000-12,000 years ago. In situ tree stumps and shellfish-rich paleobeaches are present on these drowned landscapes. A stone tool encrusted with barnacles and bryozoa were recovered from a drowned delta flood plain now 53 m below mean sea level. This is the first tangible evidence that the subaerial broad banks of the western North American Continental Shelf may have been occupied by humans in earliest Holocene and possibly late glacial time.

Did photosynthesis evolve at the earth's surface or deep in the oceans near hydrothermal vents? Such questions are engendered by the strength of the mysterious glow that emanates from these deep-sea vents. It is at these cracks in the ocean floor that very hot, mineralladen water gushes forth, and where colonies of bizarre tube worms, blind shrimp, and hyperthermophilic (high temperature-loving) bacteria thrive. (For details, see SF#60 or p. 238 in Science Frontiers, the book) The first anomaly is the strength of the glow itself. It is not all thermal radiation emitted by the 350 C water spewing forth from the vents; in fact, it is 19 times more intense than expected from theory. Something else is contributing energy, but no one knows what it is so far. The unexpected intensity of the vent glows also asks some provocative questions of the biologists: Is the glow strong enough to sup port photosynthesis? Quite likely, seems to be the answer. Are life forms in the vicinity of the vents employing photosynthesis? We don't know yet, but some bacteria do photosynthesize. Might not life and perhaps photo synthesis, too, have originated at the vents rather than on the planet's surface? This is an attractive possi bility, because very early in the earth's history the surface was ...

In other words, once a specific crystal (or life form) is synthesized, it sets up a morphogenic field that will make it easier to synthesize further the same, or nearly the same, crystal (or life form). To support his ideas, Sheldrake claims that it is common knowledge that a brand-new crystal form is difficult to synthesize at first but that further syntheses become easier and easier. The prevailing "scientific" explanation of this amazing fact is that fragments (seeds) of the initial synthesis are carried from lab to lab by humans and even the air! Morphogenic fields, however, explain such phenomena very nicely without postulating tiny crystal seeds in scientists' beards. Sheldrake then goes on to review McDougall's experiments in the 1920s in which trained rats from water mazes apparently passed their new knowledge on to their progeny. McDougall thought that he had proved the inheritance of acquired characteristics. Other biologists repeating his heretical experiments found that their first-generation rats solved the same water mazes much faster than had McDougall's rats. In addi tion, the progeny of untrained rats used as controls showed improved abilities in maze-solving with each generation, just as if their parents had been trained.

The Deep Sea Drilling Project discovered in 1970 and 1975 that layers of evaporites existed beneath the Mediterranean's floor. In addition, over 80 years ago, the bed of the Rhone River was found to consist of river sands and gravels superimposed upon hundreds of feet of oceanic sediments. Beneath these deposits -- some 3000 feet down -- was a gorge cut in granitic rock. Other rivers emptying into the Mediterranean had cut similar gorges into solid rock long ago. No one could provide an acceptable explanation for the deep-cut gorges until the evaporites proved that the water level had been low enough for the rivers to cut the gorges subaerially. In other words, the Mediterranean's level fell several thousand feet, allowing the rivers to erode gorges much as the Colorado does today in the Grand Canyon. (Smith, E.G .

Blood heated in the vicinity of the testes is pumped through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri.

My assembly of published work indicates a remote connection between quiet periods and anoxic events and suggests its form: Magnetic quiet periods coincide with fast seafloor spreading. During these periods, buoyant spreading ridges displace seawater into broad shelves, thus decreasing earth's albedo and causing global warming. Temperature gradients, and thus density gradients, from pole to equator decrease in surface waters, and the deep ocean currents of oxygenated polar waters wane. Oxygen minimum zones intensify and widen; anoxic conditions throughout entire basins are indicated by black shales deposited in the deep sea. These relations thus suggest that the earth's interior processes and its climates are related and their status recorded by both magnetic polarity and anoxic event chronologies of the earth."

This surprising result casts some light on a tricky theoretical many-body problem that has been swept under the rug for a century, and it has implications for colloids in nature and in industrial processes." (Ref. 1) Exactly what happens is not yet clear. This counter-intuitive phenomenon occurs in a many-body situation, where screening charges are established between the like-charged spheres. Although Coulomb's Law states that like charges repel one another, the presence of screening particles complicates the picture, as do the van der Waals dipole interactions. The microscopic situation may be murky, but there is no doubt on the macroscopic level that unexpected attractive forces are operating. For example, when sub-microscopic, electrically charged latex spheres are suspended in water, one would expect a homogeneous colloidal soup. Instead, the tiny, charged spheres pull themselves together in patchy, but ordered arrays. These metastable groupings of spheres are called "crystallites." Theorists are not certain what is going on.

Shortly afterwards an area to port at a distance of several hundred metres exhibited an even more amazing display of concentric circles emanating from a single point; the star board side maintained the more broken wave form but retained the same intensity of light. The vessel and deck containers were illuminated by an eerie and variable glow." (Welch, J.W .; "Bioluminescence," Marine Observer, 64:14, 1994.)

Science Frontiers ONLINE No. 45: May-Jun 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Eastern Quakes May Be Lubricated By Heavy Rainfalls Some of our continent's most powerful earthquakes have shaken the eastern half rather than the Pacific states, where the edges of tectonic plates grind together. The devastating New Madrid and Charleston quakes did not occur at plate boundaries, and it is hard to find active faults to blame for the crustal commotion. A hint of a possible solution to the dilemma comes with the correlation of earthquakes with heavy rainfalls and high water tables. For example, the Charleston quake of 1886 was preceded by two years of unusually heavy rainfall followed by a short dry spell. Also, seismicity in the New Madrid (MO) area increases 6-9 months after the Mississippi has crested. The theory is that the added water penetrates deep into the earth where it lubricates faults, causing them to become active and jolt the surface above. (Weisburd, S.; "Trickle-Down Theory of Eastern Quakes," Science News, 129:165, 1986.) Comment. The above correlations and our inability to explain deep-focus earthquakes underscore our ignorance of the mantle. To illustrate, Soviet drillers have found fluids circulating through fractured rocks 11 kilometers down, where one would expect every thing to be sealed tight by the weight of the overlying sediments.

Science Frontiers ONLINE No. 46: Jul-Aug 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Salt structures on venus?The following quotation is the abstract of a paper appearing in the Bulletin of the American Association of Petroleum Geologists. "The discovery of a surprisingly high deuterium/hydrogen ratio on Venus immediately led to the speculation that Venus may have once had a volume of surface water comparable to that of the terrestrial oceans. We propose that the evaporation of this putative ocean may have yielded residual salt deposits that formed various terrain features depicted in Venera 15 and 16 radar images. "By analogy with models for the total evaporation of terrestrial oceans, evaporite deposits on Venus should be ar least ten to hundreds of meters thick. From photogeologic evidence and insitu chemical analyses, it appears that the salt plains were later buried by lava flows. On Earth, salt diapirism leads to the formation of salt domes, anticlines, and elongated salt intrusions -- features which have dimensions of roughly 1 to 100 km. Due to the rapid erosion of salt by water, surface evaporite landforms are only common in dry regions such as the Zagros Mountains of Iran, where salt plugs and glaciers exist. Venus is far drier than Iran; extruded salt should be preserved, although the high surface temperature (470 C) would probably stimulate rapid salt flow. Venus possesses a variety of circular landforms, ten to hundreds of kilometers wide, which could be either megasalt domes or salt intrusions colonizing impact craters. Additionally, arcuate bands seen in the ...

ONLINE No. 55: Jan-Feb 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Do we really understand the dinosaurs?Until very recently, the standard dinosaur scene in the books and magazines showed huge, ungainly beasts shuffling around in lush swamps. Things are changing. Dinosaurs are now becoming more lively and talented; they may even have been warm-blooded! A recent paleontological expedition to the Gobi Desert by some Canadians will change the dinosaur stereotype even more. The Gobi dinosaur-bone sites are incredibly rich -- comparable with those in Alberta. What is most impressive, however, is the environment the Gobi dinosaurs lived in. "The dinosaurs of China and Mongolia did not live in the same type of lush, well-watered environment that existed in North America during the Mesozoic era, when dinosaurs dominated the globe. The dinosaurs of Alberta flourished on a great swampy coastal plain on the edge of a vast inland sea. In ancient China, conditions were much harsher. A modern-day equivalent would be the Great Salt Lake Basin of Utah. Water did exist in vast shallow lakes, but it was often alkaline and high in soda. The vegetation was scrubland with coniferous forests on the higher ground." (Anderson, Ian; "Chinese Unearth a Dinosaurs' Graveyard," New Scientist, p. 26, November 12, 1987.) Comment. To these Gobi observations should be added those above from northern Alaska, all of 70 north latitude, which suggest that dinosaurs also survived in a land ...

Science Frontiers ONLINE No. 13: Winter 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Violent Undersea Weather Long lines of frothing, turbulent water and transitory packets of large waves occasionally sweep across an otherwise placid sea. Usually dismissed as "rips," satellite photos reveal that these disturbances may be 125 miles long. Often several can be seen criss-crossing an ocean simultaneously from different directions. Some have a 12.5 -hour period. linking them to lunar tidal action. The surface manifestations, like the tip of the iceberg, only hint at what transpires beneath the surface. The long corridors of disturbance, moving at about 5 mph, mark where "internal waves" intersect the surface. Down be-low, submarines and other objects may suddenly rise or fall as much as 600 feet. Internal waves may in fact have caused several submarine disasters. How are internal waves created? Tid-al waters may spill over an undersea sill or ledge, creating a travelling disturbance. Some oceanographers liken the internal waves to the lee waves formed parallel to large mountain ranges. Manifestly, there is much to learn about undersea weather. (Anonymous; "Underwater Waves Held a Possible Clue to Disappearances of U.S . Submarines," Baltimore Sun, October 5, 1980.) Reference.

... has been reported for many years. During the summer of 1989, the British Columbia Cryptozoology Club (BCCC) made two expeditions to Okana gan to search out Ogopogo. Several sightings of the animal were made, as well as a video tape. The first sighting, on July 30, was quite detailed, and we quote here from the BCCC report. July 30, 1989. Four sketches of Ogopogo from different vantage points. "The focus of the investigation turned to Summerland, and a particularly good vantage point was located at Peach Orchard Beach, Lower Summerland, on July 30. All four members of the investigating team were stationed at various points on the beachfront when, at 3:55 p.m ., a most extraordinary occurrence took place. A large patch of white water materialized close to a headland at the southern end of the beach, drawing the attention of the BCCC observers. It was about 1,000 feet distant at this point, and it was clear that a large animal was swimming in a northerly direction against the prevailing wind and slight swell. At a distance of about 600 feet, Kirk Sr. was able to see clearly through a Bushnell 40X telescope that this was the classic Ogopogo, with its humps well above the water level. Both Clarks were also able to see the object clearly through binoculars. The animal displayed, variously, five and sometimes six humps. "Kirk's telescope allowed him to see that the animal's skin was whalelike, and that there were what appeared to be random calcium-like deposits under ...

The Java Sea. "At 0210 LMT I witnessed the start of a bioluminescent display. My first impression was that the ship was being 'attacked' on all sides from different directions by pulsing light-bands. A dull 'strobe-light' effect flashed through a mist, giving the bands a dirty white to gray colouration which was not a 'smooth' colour, but rather grainy in appearance. The bands were about 2 m wide and about 2 m apart and moving at speed. At first it was difficult to discern whether or not the bands were in the water or just above the surface, as no form of reflection or distortion was visible off the hull. In the end, I decided that the effect must be waterbourne if only because nothing was visible in the vessel's wake. "The most intense activity was observed on the starboard side of the ship where the phenomenon appeared to stretch as far as the horizon. At this stage, it did not appear localized, just a mass of high-speed interacting bands of light. The effect is shown in the first sketch. As is usual on an 'all aft' ship, you become 'deaf' to the constant background noises, but I gradually became aware that the pulses of light seemed to match those of the main engine's throb, that is, about two per ...
