Louis Agassiz: His Life and Correspondence

by Louis Agassiz

The next day, June 15, was spent by the whole scientific party in a ramble on shore. The landing was at the foot of a ravine. Climbing its left bank, they were led by a short walk to the edge of a large crater, which held a beautiful lake in its cup. It was, in fact, a crater within a crater, for a second one, equally symmetrical, rose outside and above it. Following the brink of this lake to its upper end, they struck across to the head of the ravine. It terminated in a ridge, which looked down upon an immense field or sea of hardened lava, spreading over an area of several miles till it reached the ocean. This ancient bed of lava was full of the most singular and fantastic details of lava structure. It was a field of charred ruins, among which were more or less open caves or galleries, some large enough to hold a number of persons standing upright, others hardly allowing room to creep through on hands and knees. Rounded domes were common, sometimes broken, sometimes whole; now and then some great lava bubble was pierced with a window blasted out of the side, through which one could look down to the floor of a deep, underground hollow.

The whole company, some six or eight persons, lunched in one of the caves, resting on the seats formed by the ledges of lava along its sides. It had an entrance at either end, was some forty feet long, at least ten feet high in the centre, and perhaps six or eight feet wide. Probably never before had it served as a banqueting hall. Such a hollow tunnel or arch had been formed wherever the interior of a large mass of lava, once cooled, had become heated again, and had flowed out, leaving the outside crust standing. The whole story of this lava bed is so clearly told in its blackened and extinct remains, that it needs no stretch of the imagination to recreate the scene. It is again, a heaving, palpitating sheet of fire; the dead slags are aglow, and the burned-out furnaces cast up their molten, blazing contents, as of old. Now it is the home of the large red and orange-colored iguanas, of which a number were captured, both alive and dead. These islands proved, indeed, admirable collecting grounds, the more interesting from the peculiarity of their local fauna.

FROM AGASSIZ TO PROFESSOR PEIRCE.

OFF GUATEMALA, July 29.

. . .Our visit to the Galapagos has been full of geological and zoological interest. It is most impressive to see an extensive archipelago, of MOST RECENT ORIGIN, inhabited by creatures so different from any known in other parts of the world. Here we have a positive limit to the length of time that may have been granted for the transformation of these animals, if indeed they are in any way derived from others dwelling in different parts of the world. The Galapagos are so recent that some of the islands are barely covered with the most scanty vegetation, itself peculiar to these islands. Some parts of their surface are entirely bare, and a great many of the craters and lava streams are so fresh, that the atmospheric agents have not yet made an impression on them. Their age does not, therefore, go back to earlier geological periods; they belong to our times, geologically speaking. Whence, then, do their inhabitants (animals as well as plants) come? If descended from some other type, belonging to any neighboring land, then it does not require such unspeakably long periods for the transformation of species as the modern advocates of transmutation claim; and the mystery of change, with such marked and characteristic differences between existing species, is only increased, and brought to a level with that of creation. If they are autochthones, from what germs did they start into existence? I think that careful observers, in view of these facts, will have to acknowledge that our science is not yet ripe for a fair discussion of the origin of organized beings. . .

There is little to tell for the rest of the voyage that cannot be condensed into a few words. There was a detention for despatches and for Coast Survey business at Panama,—a delay which was turned to good account in collecting, both in the Bay and on the Isthmus. At San Diego, also, admirable collections were made, and pleasant days were spent. This was the last station on the voyage of the Hassler. She reached her destination and entered the Golden Gate on the 24th of August, 1872. Agassiz was touched by his reception in San Francisco. Attentions and kindnesses were showered upon him from all sides, but his health allowed him to accept only such hospitalities as were of the most quiet and private nature. He passed a month in San Francisco, but was unable to undertake any of the well-known excursions to the Yosemite Valley or the great trees. Rest and home became every day more imperative necessities.

In October, 1872, Agassiz returned to Cambridge. To arrange the collections he had brought back, to write a report of his journey and its results, to pass the next summer quietly at his Nahant laboratory, continuing his work on the Sharks and Skates, for which he had brought home new and valuable material, seemed the natural sequence of his year of travel. But he found a new scheme of education on foot; one for which he had himself given the first impulse, but which some of his younger friends had carefully considered and discussed in his absence, being confident that with his help it might be accomplished. The plan was to establish a summer school of natural history somewhere on the coast of Massachusetts, where teachers from our schools and colleges could make their vacations serviceable, both for work and recreation, by the direct study of nature. No sooner was Agassiz once more at home than he was confronted by this scheme, and he took it up with characteristic ardor. Means there were none, nor apparatus, nor building, nor even a site for one. There was only the ideal, and to that he brought the undying fervor of his intellectual faith. The prospectus was soon sketched, and, once before the public, it awakened a strong interest. In March, when the Legislature of Massachusetts made their annual visit to the Museum of Comparative zoology, Agassiz laid this new project before them as one of deep interest for science in general, and especially for schools and colleges throughout the land. He considered it also an educational branch of the Museum, having, as such, a claim on their sympathy, since it was in the line of the direct growth and continuance of the same work. Never did he plead more eloquently for the cause of education. His gift as a speaker cannot easily be described. It was born of conviction, and was as simple as it was impassioned. It kept the freshness of youth, because the things of which he spoke never grew old to him, but moved him to the last hour of his life as forcibly as in his earlier years.
