Kaufmann is a zoologist with strong proclivities for wood-turtle watching. Not a very strenuous vocation you say! Be that as it may, wood turtles make up for their lack of speed with some interesting talents. Besides being able to home accurately over unfamiliar terrain, they also know how to "grunt" - not vocal grunting, but a much more curious activity. Kaufmann relates one of his observations: "I came upon an adult male. When I first saw him he was sitting quietly beside a creek, but he soon wandered into a damp thicket of alder, spicebush, and false hellebore. Before disappearing from sight, however, he began to rock back and forth. I followed, trying to stay just close enough to see what he was up to without disturbing him. Fortunately, he did not scare easily, which allowed me to approach within a few yards as he meandered, walking and rocking. First, I noticed that the rocking was caused by short bouts of stomping with the front feet, alternating between left and right. Then he suddenly jabbed his head at the ground and ate something. This behavior continued for a half hour, and several times I caught a glimpse of the prey - earthworms snatched from the surface. I suddenly realized the turtle was 'grunting' for worms!"

The ra-dii of the rings depend upon the energies of the particles emitted by the radioactive elements. Each type of radioactive decay has a specific half-life. Thus, the patterns of radiohalos help measure the age of coalified wood. A challenge to geology arises because the radiohalos in coalified wood from Jurassic and Triassic formations, supposedly millions of years old, suggest ages of only a few thousand years.

Little grows there today, but there is on these icy shores the remnant of a forest that flourished 45 million years ago, according to conventional geological dating of the strata. A University of Saskatchewan scientist, J. Bassinger, has been studying the 15-20 layers of stumps, some with diameters of 3 feet, and logs up to 30 feet long. Even rather blackish leaves survive in the soil. This once lush forest boasted trees like dawn redwoods and water firs; being analogous to Florida's Cypress Swamp in the Everglades. So excellent is the preservation of the forest that its wood cuts as if it were recent lumber and burns readily. (Howse, John; "Forestry Frozen in Time," Maclean's Magazine, p. 55, September 8, 1986. Cr. B. Ickes) Comment. Question 1: Even if the earth was warmer 45 million years ago, could a tropical-type forest survive the nearly six months of total darkness at Axel Heiberg Island? Question 2: Can wood be preserved so well for so long? In the postulated warmer climate, there must have been many chemical and biological agents to promote rotting. Also relevant is the discovery, reported below, that wood that floats and burns with ease has been found in Antarctica. This Antarctic wood has been dated at 3 million years.

Conventional wisdom insists that the continent has been ice-covered for over 15 million years. But now Peter Webb and his coworkers have found pollen and the remains of roots and stems of plants in an area stretching some 1300 kilometers along the Transantarctic Mountains. The Antarctic wood is so recent that it floats and burns with ease. Webb's group postulates that a shrub-like forest grew in Antarctica as recently as 3 million years ago. The dating, of course, is critical, and is certain to be subjected to careful scientific scrutiny. Nevertheless, these deposits of fresh-looking wood do suggest that trees recently grew only 400 miles from the South Pole. Also of interest is the fact that the sedimentary layers containing the wood have been displaced as much as 3000 meters by faults, indicating recent large-scale geological changes.

Zoologists have discovered that it taps wood to locate cavities under the surface. Its skills are so well developed that it can tell holes containing grubs from those that are empty. It is the only mammal known to use such a technique." To improve the efficiency of its "percussive foraging," the aye-aye has evolved huge bat-like ears and a highly elongated middle finger on each hand. This specialized finger does the tapping and the big ears relay the nuances of sound to the brain. So sensitive is this specialized form of sonar that the ayeaye can detect grubs 2 centimeters below the surface of the wood. Once a grub has been located, the aye-aye tears into the wood with its forwardcurving, chisel-like teeth. The incisors are remarkable for a primate, for they keep on growing, just like those of rodents. When the grub-containing chamber has been reached, the long, narrow middle finger is inserted and the grub is retrieved. A neat combination of attributes. What is even more interesting is a comparison of the aye-aye with many of the woodpeckers. Many woodpeckers also employ percussive foraging, have special bills for chiselling, and possess very, spiny tongues for extracting grubs ...

The January 1989 issue of the Tennessee Anthropologist contains a long article on the Bat Creek Stone by J.H . McCullock, of Ohio State University. We rely here upon a summary written by R. Strong. "The Bat Creek Stone has generated so much controversy, yet it was excavated in an undisturbed burial mound in 1889 under the direction of Cyrus Thomas, Project Director of the Bureau of American Ethnology's Mound Survey, a part of the Smithsonian Institution. There could be no question of forgery because it was found under the head of one of the nine skeletons that were excavated. Pieces of wood presumed to be the remains of wooden earspools were preserved in the Smithsonian's collections as were a pair of brass C-shaped bracelets. Thomas immediately declared the nine characters on the stone to be Cherokee and the burial assumed to be post-contact - what else could the bracelets be but trade items or native copper?" That would seem to be the end of the story, but some language students failed to see any resemblance between the Bat Creek Inscription and the written Cherokee language. Further, C. Gordon, admittedly a proponent of early Phoenician contact with the New World, declared that the Bat Creek characters were Paleo-Hebrew, a family of languages that includes Phoenician.

Fraser noticed that some trees in the dark woods glowed spectacularly in the car's headlights -- almost as if they were covered with snow. Obviously snow was out of the question. Instead, the glow was some form of reflection from dew-covered leaves, and only from certain species of trees at that. "Later nocturnal expeditions with a powerful flashlight (a proceeding that aroused dark suspicions in at least one local gamekeeper) showed that it favoured only certain types of conifer and a few shrubs such as the yew and rhododendron. The explanation lies in the contact angle of the droplets on the leaves: as this rises above 90 degrees or so, the proportion of light from the car's headlamps that is reflected back towards the occupant increases, and for angles above 140 degrees, the retroreflection becomes spectacular. Blue spruces show the glow particularly well." (Matthews, Lindsay; "Reflections on a Summer's Night," Nature, 369:441, 1994.) From Science Frontiers #95, SEP-OCT 1994 . 1994-2000 William R.

... little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm the immense amounts of gases precariously locked up in sea-floor sediments. The stratum of gas hydrates in the Blake Ridge alone covers 26,000 square kilometers -- enough gas is there to supply the U.S . for 107 years.

Upper-class women (perhaps men, too) favored green, white, and black makeup. These cosmetic powders, dating from 2,000 B.C ., have been exceptionally well preserved in their original vials made of alabaster, ceramic, and wood. A team of French chemists led by P. Walter was not surprised when their analyses of these powders found crushed galena and cerussite (two ores of lead). However, they nearly dropped their test tubes when they also found chemical compounds that are extremely rare in nature; specifically, laurionite (PbOHCl) and phosgenite (Pb2 Cl2 CO3 ). In fact, these compounds are so rare naturally that the Egyptian powders must be artificial. P. Walter et al wrote: "Taken together, these results indicate that laurionite and phosgenite must have been synthesized in Ancient Egypt using wet chemistry. The Egyptians manufactured artificial leadbased compounds, and added them to the cosmetic product. The underlying chemical reactions are simple, but the whole process, including many repetitive operations, must have been quite difficult to achieve." It had been recognized earlier that the Egyptian chemists had used fire-based technology 500 years earlier (2 ,500 B.C .) to manufacture blue pigment.

About the size and shape of a dog, it was covered with stripes that ran from its shoulders across its back to its thick, rigid, tail. "The animal stood still as the startled ranger counted the stripes, then it nonchalantly gave an enormous jaw-stretching yawn. But when the ranger reached for his camera, the creature faded into the undergrowth, leaving nothing but a rank smell.

Pushing on, he was crossing an exposed snow slope at 13,000 feet, when his run was halted by a wet snow avalanche. Moving closer to the avalanche to assess the snow's stability, he again saw the strange tracks heading across the slope to a small bush. "Behind the bush stood an erect entity over 6 feet tall. The figure, of general human proportions and stance, remained immobile, seemingly looking down the slope. 'The head was large and squarish, and the whole body appeared to be covered with dark hair.'" Wooldridge quickly snapped several photographs. He then advanced to with-in 500 feet of the entity and took more pictures. After 45 minutes of observa tion, Wooldridge decided to continue his journey. When asked why he did not approach the figure to force it to move or react, he stated that he got as close as he felt it was safe, being concerned about snow stability, the creature itself, and his solitary situation.

To make bark paper, one first takes the inner layer of bark, or bast, from a tree. This material is then thinned, widened, and made flexible by soaking it in water and beating it. The final product retains much of the bark's structure with its interconnecting fibers. Ordinary paper today is also made of wood fibers, but the original fiber interconnections are destroyed in the pulping process. The manufacture of bark paper requires characteristic grooved beaters, specimens of which have been found in both Mesoamerica and Southeast Asia. Were bark paper and the tools required to make it invented independently on both sides of the Pacific, or were they transported across the Pacific by early navigators? If the latter, the flow was probably from Asia to America because the paper-making tools first appeared in Southeast Asia 4-5000 years ago and in Mesoamerica only 2500 years ago. Even so, trans-Pacific voyages 2500 years ago are definitely not part of acceptable archeology. Anthropologist P.

So, where did they come from? But origin is only part of the problem. The presumable non-glacial erratics occur in a geologically confused area that seems to be upsidedown time-wise according to the few fossils that have been found. One theory is that the erratics were long ago carried to great depths by the conveyor-belt layers that slide eastward and downward under the U.S . Pacific Coast. Later, geological pressures squeezed the rock containing the erratics back to the surface like toothpaste. In the last phase, the matrix rock was eroded away leaving the erratics orphans.

Halos produced by the alpha particles emitted by Po218 are found in granite rocks in many areas. Yet, the half-life of Po218 is only 3 minutes. Since the Po218 has no identifiable pre-cursors in the rock, ". .. how did the surrounding rocks crystalize rapidly enough so that there were crystals available ready to be imprinted with radiohalos by alpha-particles from Po218 ? This would imply almost instantaneous cooling and crystallization of these granitic minerals -- and we know of no mechanism that will remove heat so rapidly; the rocks are supposed to have cooled over millennia, if not tens of millennia." In coalified wood dated as older than 200 million years, the ratio between U238 and Pb206 should be low. It is actually very high.

Zoologists already knew that Puerto Rican white-lipped frogs use vibrations to communicate amongst themselves. The Malaysian tree frog can now be added to the list of substrate vibrators. The female will sit on a reed or small sapling and tap out a "come-hither" message with her toes. The message goes forth in minute seismic waves. The males detect these vibrations and proceed, sometimes in great numbers, to the source of the vibrations, and the species is thereby perpetuated.

The different bedrocks underlying the various forests supply different quantities of such trace elements as barium and manganese. Preliminary results suggest that the early building period in Chaco Canyon, circa 900 AD, employed trees from many different sites. During the peak building period a century later, all logs used carried the same concentrations of trace elements and, therefore, probably came from the same forest. Durand's next step is to locate this forest and figure out how the builders of Chaco Canyon, the Anasazi, managed to tote the logs, some weighing 600 pounds, 50 miles or more.

Perhaps they think a mole is tunneling after them, or maybe rain is beating down above. Whatever goes through their "minds," they emerge on the surface in response to vibrations and may be snapped up by several species that know their weakness. Human fishermen know the worms' weakness and "grunt" for them in several ways; say, by drawing a notched stick across the trunk of a small tree to generate vibrations. Wood turtles are said to "stomp" for worms. (SF#65) Kiwis and Kagus also stomp for their dinner. (Kagus are rather strange birds found in New Caledonia.)

Here's the mechanism: plant leaves reflect infrared light well, so when a tomato plant's pigments detect a lot of infrared, the plant "thinks" that it may be crowded out by competing vegetation. The tomato plant responds aggressively by growing more rapidly. The red plastic mulch between the rows also reflects a lot of infrared light, and it thereby tricks the tomato plant into accelerating its growth.

The beetle Melanophila acuminata seeks out forests that have just been ravaged by fires so that it can lay its eggs in the nutritious, freshly burnt wood.

When an archeologist finds the contents of ancient garbage dumps (" middens") fused into a glassy slag. he has to ponder a bit longer. First, a bit of background. Natural glasses can be created in several ways. Impact-heating by meteorites or asteroids probably fused the famous slabs of Libyan Desert Glass and also the Darwin glass found in Australia. More curious are the peculiar glassy clinkers of fused wood ash found in hollow snags in trees after intense forest fires. This is called "combustion metamorphism." Combustion metamorphism is also common where undergound coal seams have caught fire and burn for decades. Humans get into the act, too. The ancient Scots piled up trees around their rock forts and fused the stones together with fire. (Why they bothered is unknown.) However, a different sort of natural glass has been found in east-central Botswana. There, archeologists have found 5-inch-thick layers of glassy slag interleaved with ashy soil in ancient middens (garbage dumps). These middens are not associated with pottery kilns or iron smelting. It is hard to imagine what could have melted layers of garbage, including pottery, plant material, and other biomass. Analysis of the slag indicates that temperatures of 1155-1290 C were required to fuse the garbage. Open fires could ...

These plastic-like coatings are produced by bacteria and fungi. Sure enough, microscopic examination of a few linen fibers from the Shroud of Turin show that they, too, are coated with such varnishes. These biogenic varnishes may introduce carbon that has been recently fixed from the atmosphere and thus make the sample's age appear younger than it really is.

The New Zealand Department of Conservation asked geologist P. Wood for his assessment. "He identified the rock as the 330,000-year-old Rangitaiki Ignimbrite. Following the line of blocks both horizontally and vertically, and photographing them in series, he revealed a system of joints and fractures natural to the cooling process in ignimbrite sheets. What Brailsford [see SF#107] had taken to be manmade cut, stacked blocks were no more than a type of natural rock formation." P.
