As to the extent of time during which there was no life, we have no means of determining. That it was almost infinitely long is made apparent by the researches of eminent scholars on the cooling of lava. Toward the close of this extended period of time faint traces of life appear. Not life as we are apt to think of it. No nodding flowers were kissed by the sunshine of this early time. The earliest forms of flowerless plants, such as sea-weeds, and in dry places possibly lichens covering the rocks, were the highest forms of vegetable life. Animal life, if present, for the fact is denied by some, occurs in the very lowest form, merely structureless bodies, with no especial organs of sense, or nutrition: and their motion consisting simply in protruding and withdrawing hair-like processes.<4> Such was the beginning of life. This vast period of time, which includes the beginning, is known among geologists as Archean time.
No one can doubt but that this deposit of cave earth itself requires a prolonged time for its accumulation.<8> But this period, however prolonged, at length comes to an end. From some cause, both animals and man again abandoned the cave. Another vast cycle of years rolls away--a time expressed in thousands of years--during which nature again spread over the entombed remains a layer of stalagmite, in some places equal in thickness to the first formation. Above this layer we come to a bed of mold containing remains of the later Stone Age, of the Bronze, and even of the Iron Age. Below the first layer of stalagmite--the completed biography of Paleolithic times; above, the unfinished book of the present. Such are the eloquent results obtained by the thorough exploration of one cave. The results of all the other explorations, in a general way, confirm these. Mr. Dawkins explored a group of caverns in Derbyshire, England. These caverns and fissures are situated in what is known as Cresswell Crags, the precipitous sides of a ravine through which flows a stream of water dividing the counties of Derby and Nottingham.
Attempts were made by the early colonists to grow other crops which, for various reasons, did not thrive at Jamestown. Some plants, like bananas, pineapple, citrus fruits, and pomegranates, could not withstand the cold Virginia winters. Other plants, including rice, cotton, indigo, sugarcane, flax, hemp, and olives, did not grow vigorously for one reason or another, and repeated efforts to cultivate them usually resulted in failure. Mulberry trees grew well at Jamestown (the leaves were used to feed silk worms), but attempts to make silk were not successful commercially.
