March, 1880. THE WEST SHORE. 79 MAN'S PREHISTORIC PROGRESS. Tho caves, tombi and gravol drifta of the earth, which are of all objeoU the most uniii tcrstiu lu llju casual observer, have m our days become strangely eloquent At the touoh of acience they have lent a voico to the dumb past. Railing tho voil of antiquity, they have unrolled page after page of ancient history, written neither with pen, nor pencil, but atamped on the rude implement of war or the chase, imprinted on the few threads of decaying tissue that iuwrap tho crumbling skeleton, en graved on the bracelet of bronze or silver that encircled tho slender wrist of some prehistoric beauty, or chased on the brooch of gold that clasped the mantle of some renowned but for gotten chieftain. So exact are the deductions to bo drawn from these mute records of the past that they have been dividod into four well-denned ages -thodrift age, the age of polishod stone, the age of bronze aud the age of iron; each of these marking an advance in knowledge and civilization which amounted to a revolution in the then existiug manners and customs of the world. The drift age or paleo lithic period is marked by deiwsita of rude stouo implements ; to it succeeds the neolithic, or age of polished stono, in which the Bame stono im- Elements were in use, but of a superior class, ighly polished and well tinished. The wandoring savage who lived by tho chase and out up his prey with the rude, unpolished Hint knives of the paleolithic ago was coeval with many extinct animals whioh then ranged over the forests that in thoso oarly times quite generally covered the earth. In the eaves tho rudest occupy tho lowest strata ; showing that even in that remote age man had the same ten dency to improve as now. Somo of the remains of tho ancient Nimrods have been found in caves and sepulchral tumuli; and of all the living races of men they rosomble the Esquimaux most closely. With them are found the remains of such extinct animals as the cave bear, mammoth and woolly rhinooeros. The neolithic era marked the dawn of a now and higher civilization. In many parts of Eng land, collections of polished stone implement have been found, such as stone axes and adzes, chisels, gouges, small saws, hammers, awls fur boring, stone picks for turning up tho soil, pestles, mortars, querns anil spindle-whorls. Needles have also leeu found, which imply a knowledge of the art of sewing ; ami vesnoli of rude earthenware, which show that these old world folks oould ply the potter's orsft with a considerable degree of deftuess. They pos sesaed the horse, a small short-horned ox, two kinds of swine, goats and horned sheep, with dogs of a large breed. Their dwellings seem to have consisted of pits roofed with wattle. They were all built, or, rather, soooiiod out upon one plan. There was a circular shaft for an entrance, going down to a depth of from seven to eight feet, five to seven feet wide at the bot tom, and narrowing to three at the top ; and rouud this was a chamber or cluster of chambers. In these huts are found a variety of polished .ton,, imulauieuta. bone of the domesticated animals and shred! of pottery. The Hint of which these stone implement are made was ob tained by quarrying for the Hint nodules in the chalk. Many of these mine with the mining tool still remain. In some instances, caves seem to have lieen imed as dwellings; and, where not employed a a shelter for the living, have been frequently selected as a rating-placo for the dead. lu these cave mausoleums, numerous skeletons of both sexes and of all age are found, Prom the quantities of oalcined bone found in some of these grave, it is lielived that, in the case of a chief, human sacrifice may have been offered. Kroni the number of the tomb and dwellings, we are led to the conclusion that Europe had in those days a somewhat huge and tolerably civil ised population, who bad llock and nerd, who practiced agriculture, and who were hunters and fishermen. , la the lak dwelling! of Switzerland, which are assigned to this era, many interesting dit coveries have been made. Three kind of wheat have been found; also two kinds of bar ley, two kinds of millet, the remains of fruit IQOh oppiua aud pears, pea, Max and weeds. For their oattle and swine the lake dwellers seem to have laid up winter fodder in tho shape of aoorns and lieechouts. They mado oloth of tho flax, and oould even weave it into au orna mental pattern. However aciiuired, the possession of brnnxo marks an era of advancement. Tho dwellings of tho people who used it woro better, and their circumstances more comfortable than the tribes they suoceoded. They hail axes and sickles of brouze, gouges, chisels, hammers and knives; aud, as a natural consequence, all the products of their labor were superior and hot tor finished. They could weave well a tough and strong fabrio, and their olothes were formed of several pieces sowed together. Their cloth is almost invariably of linen no woolen oloth be longing to this period having been found either in Franco or Switzerland; but In a wooded cof fin discovered in Im;i at Itibe, in Jutland, the remains of a body was found inclosed in a uloak of coarse woolen cloth; a woolen cap covered the head, tho lower limbs wrapped in woolen loggings. Another 00 An oontained tho par phernalia of an ancient hollo, a brooch, a knife, a double-pointed awl, and a pair of tweezers all of bronze, two studs, one of bronie and one of tin, and a javelin head of flint, liodio wrapHl in woolen cloth have also lieen found in llritain. It is, however, worthy of remark that it is only in the exceptional cases in which the body is turned into adipoooro (an unctuous, waxy sub stance), that woolen oloth is found; in normal circumstances that fabriu would disapioar far more rapidly than linon. Tho bronze remains found in the Rhono val ley prove that the art of iiietal-working, once acquired, was earned by theao early raoea to great perfection. They were aeqiiainted with mo processes in coming, tempering, mumping and engraviug metal. With this discovery of a new art came a simultaneous improvement lu the potter's craft; tho rude cuia of the neo lithic age disapiear, and are succeeded by ves sels of an ondluaa variety of form and ornamen tation, some of which aro extremely lieautiful. Some of the vases are inlaid with tin, others aro marked with the same patterns employed to dec orate the Etruscan vases of Italy; while other, found in the pilo dwellings of the Lake of Hour get, have representations of men ami animals. The oolleotinus of bronze jewelry sre also abun dant and curious. They consist of hraeolota, armlets, long hairpins with decorated heads, riugs, ear-rings, uirdlrs adorned with pendant. bronchos, buttons, studs aud torques for the neck. In primeval times, many animals were abun dant all over Europe, which seem gradually to have disappeared, such a the cave-hyena, the cave-lion, the mammoth, the woolly-haired rhi noceros, the hipMipntamus, the musk -ox, the Irish elk, the wild horse, the glutton, the rein deer, the auroch, ami the urus or wild ox. With n giid to the antiquity of man, Sir John Lubbock comes to the conclusion that man certainly oxisted in Western Europe dur ing the period of the mammoth, and the pre sumption is that he alto existed iu pliocene and even in miooen time; but tho proofs of that sre to be sought, he thinks, in warm, almost in tropical climate. Prom the manners and customs of modern lavages much light msy lie thrown upon the early condition of prehistoric man. After con sidering the condition and progress of the Hot tentot, South He Islander, Esquimaux and other, Sir Johu l.uhbnck remarks that, " It ia imprawible not to admire the skill with whioh they use their weapons and implements, their ingenuity in hunting and fishing, and their elisx and accurate powers of observation." My all these qualities wa msy suppn prehistoric man to have been distinguished in at least an equal degree. It is evident that man whan h drat spread over the surface of the earth most have been in a oondition represented by the low est t vpe of savage. Then by alow degrees, by imitation, and by tho leaching of experience, the capacity of Infffrinir and elothln. hfaloif, ... sj lase.! . ing his simple implement, would develop and expand, until man, physically one of the weak est and moat unprotected of all animals, would, by dint of that subtile force whioh we term mind, make himself independent of nature, and at last, "monarch of all he surveyed," and able to cope in his native coverts with the shaggy lion, and overtake in the chase the fleet stag or hounding antelope. The wild man, like the wild beast, la always timid, always auspicious, always on the watch ; and the condition of the sago woman Is still more cruel, " She sharaa," says Sir John I.uh bock, "all the sufferings of her mat, and haa also to bear his ill humor and ill-usage, Eveu the possession of beauty, far from being an a! leviation, is only an aggravation of tho evil of her lot, by securing tor her a hanl thralldom to many maatare." With growing civilization, on the other hand, come security and eoiilldonoe, and that sense of justice and honor which ia the liest pmteotinu of the weak ; and with the increasing and ame liorating inlliienuea of soienoe, a great improve ment may still be looked (or In the condition of our race.
