 vegetable and partly an animal feeder, more industrious, 

 provident, and progressive ; while within the polar 

 regions, where warmth has to be sustained by diet, 

 and where his whole time is spent in securing a pre- 

 carious subsistence, he is solely an animal-feeder, 

 toilsome but stationary. As man now subsists under 

 these broad climatic distinctions, so he must have sub- 

 sisted in former ages ; and thus he may have been in 

 turns chiefly a vegetable-feeder or chiefly an animal- 

 feeder, according to the distributions of sea and land, 

 and the climates thereby engendered. As the Esqui- 

 maux, in virtue of their position, are strictly animal- 

 feeders, and have even no name for the fruits and 

 grains, so during the Glacial Epoch in Europe a race 

 of men may have subsisted by hunting and fishing 

 among the glaciers on land and the icebergs on water. 

 We mention this, in passing, to show how futile the 

 arguments of those who contend that man was only 

 called into being with, and could not have subsisted 

 without, the fruit-bearing and grain-yielding plants of 

 the present day, and thus would limit his antiquity 

 to a chronology of their own creating. The limits of 

 man's endurance, and the conditions under which he 

 can subsist, are vastly wider and much more multi- 

 farious than civihsed reasoners are generally prone to
