FROM OSWALD HEER.
ZURICH, December 8, 1868.
MY HONORED FRIEND,
Your letter of last May gave me the greatest pleasure, and I should have answered it earlier had I not heard that you had gone to the Rocky Mountains, and supposed, therefore, that my letter would hardly find you at home again before the late autumn. I will delay writing no longer,—the more so because I have received, through the Smithsonian Institution, your great work on the Natural History of the United States. Valuable as it is in itself, it has a double attraction for me as the gift of the author. Accept my warm thanks. It will always be to me a token of your friendly regard. It gave me great satisfaction to know that my Fossil Arctic Flora had met with your approval. Since then many new facts have come to light tending to confirm my results. The Whymper Expedition brought to England a number of fossil plants, which have been sent to me for examination. I found eighty species, of which thirty-two from North Greenland are new, so that we now know 137 species of Miocene plants from North Greenland (70 degrees north latitude). It was a real delight to me to find the fruit cup of the Castanea [chestnut] inclosing three seeds (three Kastanica) and covered with prickles like the Castanea vesca; and, furthermore, I was able to prove by the flowers, which were preserved with the fruit, that the supposition given in the Arctic Flora (page 106) was correct; namely, that the leaves of the Fagus castaneafolia Ung. truly belong to a Castanea. As several fruits are contained in one fruit cup, this Miocene Castanea must have been nearer to the European species (C. vesca) than to the American Castanea (the C. pumila Micha). The leaves have been drawn in the Flora Arctica, and are also preserved in the Whymper collection.
I have received very beautiful and large leaves of the Castanea which I have called C. Ungeri, from Alaska. I am now occupied in working up this fossil Alaskan flora; the plants are in great part drawn, and contain magnificent leaves. The treatise will be published by the Swedish Academy in Stockholm; I hope to send you a copy a few months hence. This flora is remarkable for its resemblance to the European Miocene flora. The liquidambar, as well as several poplars and willows, cannot be distinguished from those of Oeningen; the same is true of an Elm, a Carpinus, and others. As Alaska now belongs to the United States, it is to be hoped that these collecting stations, which have already furnished such magnificent plants, will be farther ransacked. . .Hoping that you have returned safely from your journey, and that these lines may find you well, I remain, with cordial greeting,
Sincerely yours,
OSWALD HEER.
Shortly after Agassiz's recovery, in July, 1868, he was invited by Mr. Samuel Hooper to join a party of friends, tired members of Congress and business men, on an excursion to the West, under conditions which promised not only rest and change, but an opportunity for studying glacial phenomena over a broad region of prairie and mountain which Agassiz had never visited. They were to meet at Chicago, keep on from there to St. Paul, and down the Mississippi, turning off through Kansas to the eastern branch of the Pacific Railroad, at the terminus of which they were to meet General Sherman with ambulances and an escort for conveyance across the country to the Union Pacific Railroad, returning then by Denver, Utah, and Omaha, and across the State of Iowa to the Mississippi once more. This journey was of great interest to Agassiz, and its scientific value was heightened by a subsequent stay of nearly two months at Ithaca, N.Y., on his return. Cornell University was then just opened at Ithaca, and he had accepted an appointment as non-resident professor, with the responsibility of delivering annually a course of lectures on various subjects of natural history. New efforts in behalf of education always attracted him, and this drew him with an even stronger magnet than usual, involving as it did an untried experiment—the attempt, namely, to combine the artisan with the student, manual labor with intellectual work. The plan was a generous one, and stimulated both pupils and teachers. Among the latter none had greater sympathy with the high ideal and broad humanity of the undertaking than Agassiz.* (* Very recently a memorial tablet has been placed in the Chapel at Cornell University by the trustees, recording their gratitude for the share he took in the initiation of the institution.)
Beside the enthusiasm which he brought to his special work, he found an added pleasure at Cornell in the fact that the region in which the new university was situated contained another chapter in the book of glacial records he had so long been reading, and made also, as the following letter tells us, a natural sequence to his recent observations in the West.
