Rh an arctic life, and that many remained and, with the gradual amelioration of the climate, their descendants changed in their habits so far as to meet the requirements of a temperate climate. This explanation, it seems to me, best accords with known facts.

It is fitting, after a long tramp in search of human relics or remains, still so abundantly scattered over and through the superficial soil, to halt, at the day's close, upon the river's bank, and rest upon one of the huge ice-transported bowlders that reach above the sod. From such a point I can mark the boundary of the latest phenomenon of the valley's geological history, and seem to see what time the walrus and the seal sported in the river's icy waters; what time the mastodon, the reindeer, and the bison tenanted the pine forests that clad the river's banks, and what time an almost primitive man, stealing through the primeval forests, surprised and captured these mighty beasts what time, lingering by the blow-holes of the seal and walrus in the frozen river, surprised and killed these creatures with so simple a weapon as a sharply chipped fragment of flinty rock. And, as the centuries rolled by, and the river lessened in bulk, until it but little more than filled its present channel, there still remained along its shores the more cultured descendants of the primitive chipper of pebbles. As a savage, so like the modern Eskimo that he has been held to be the same, this pre-Indian people still wrought the argillite that their ancestors were forced to use for their palæolithic tools; and as these spear-points are being gathered from the alluvial deposits of the more modern river, I can recall to their accustomed haunts this long-gone people, who, ere they gave place to the fierce Algonkin, were the peaceful tenants of this river's valley. Then, as we gather the beautiful arrow-heads of jasper and quartz, and pick from superficial soils grooved axes, celts, chisels, curiously wrought pipes, strange ornaments, ceremonial objects, and fragments of pottery, literally without number, we marvel at the skill of those who wrought them, and faintly realize how long these comparatively recent comers must have dwelt in this same valley, to have accumulated such an endless store of these imperishable relics.

We rightly speak of the antiquity of the Indian, but, remote as is his arrival on the Atlantic coast, it is modern indeed, in comparison with the antiquity of man in the same region. We can think of it, and perhaps faintly realize it, as "time relative," but in no wise determine it as "time absolute."

foresees another division in science. He observes, in a biological paper in the British Association, that morphology and physiology have now diverged so widely, as regards subject and method, that there seems to be danger of a complete separation of one from the other.
