No one who had seen them upon the track of our present glaciers could hesitate as to the real agency by which all these erratic masses, literally covering the country, have been transported. I have had the pleasure of converting already several of the most distinguished American geologists to my way of thinking.” Henry David Thoreau took Agassiz’s book out of the Harvard library and returned it a few weeks later-perhaps unread. Apparently, Thoreau never knew that Walden Pond was a glacial kettle, had no idea that he lived among moraines and drumlins, icetransported hills. Although he and Agassiz were co-working space rotterdam acquainted and shared the same part of Massachusetts for sixteen years, there is in Thoreau’s work no discussion of glaciation. Thoreau evidently never suspected that all his N ausets and Chesuncooks, Merrimacks and Middlesex ponds had been made and shaped by ice. Agassiz was so caught up in glacial and general geology that he would try to teach it to stagecoach drivers. He believed that anyone, given a little help, could understand the nature of the earth. In Boston, in order to make his case perfectly and avoid the rockslides of his Franco-Germanic accent and syntax, he announced that he would give a series of lectures in French on the Epoque Glaciaire. People paid to hear it, and he preserved their admiration in recrystallized mots justes. When he spoke of the Jura, the Pennine Alps, and the boulders in the valleys between, no one was as co-working space almere moved as Agassiz. His great range of expression did not exclude tears. With his large forehead, full lips, aquiline nose, and shoulder-flowing hair, he all but held a baton in his hand with which to conduct the movements of the ice. One Saturday a month, he met with his friends for a late, seven-course lunch from which no one was in a hurry to go home.
