In the midst of all this, Agassiz turned his glance upon the glaciers, and the "local phenomenon" became at once a cosmic one. So far a happy divination; but he seems to have believed quite to the last that, not only the temperate zones, but whole intertropical continents--at least the American--had been sheeted with ice. The narrative in the first volume will give the general reader a vivid but insufficient conception of the stupendous work upon which he so brilliantly labored for nearly a decade of years. _Coelum, non animum, mutant_ who come with such a spirit to a wider and, scientifically, less developed continent. First as visitor, soon as denizen, and at length as citizen of the American republic, Agassiz rose with every occasion to larger and more various activities. What with the Lowell Institute, the college in Charleston, S. C., and Cornell University, in addition to Harvard, he may be said to have held three or four professorships at once, none of them sinecures. He had not been two months in the country before a staff of assistants was gathered around him, and a marine zooelogical laboratory was in operation. The rude shed on the shore, and the small wooden building at Cambridge, developed under his hand into the Museum of Zooelogy--if not as we see it now, yet into one of the foremost collections. Who can say what it would have been if his plans and ideas had obtained full recognition, and "expenditure" had seemed to the trustees, as it seemed to him, "the best investment;" or if efficient filial aid, not then to be dreamed of, had not given solid realization to the high paternal aspirations? In like manner grew large under his hand the Brazilian exploration, so generously provided for by a Boston citizen and fostered by an enlightened emperor; and on a similar scale was planned, and partly carried out, the "Contributions to the Natural History of the United States," as the imperial quarto work was modestly entitled, which was to be published "at the rate of one volume a year, each volume to contain about three hundred pages and twenty plates," with simple reliance upon a popular subscription; and so, indeed, of everything which this large-minded man undertook.
