Charles Frederick Hartl. 121 



Buffalo Seminary, Buffalo, N". Y., of which her mother, 

 for several years past, has been the principal. 



While at Cornell University, when not occupied with 

 college duties, he was engaged in working up the results of 

 his Brazilian explorations, and in preparing his report as 

 geologist of the Thayer Expedition. This report, however, 

 grew to so great a size, and was so complete in itself, that 

 it was found advisable to publish it separately i n 1870 as 

 "The Geology and Physical Geography of Brazil." It 

 forms a large octavo volume of over six hundred pages, and 

 contains in addition to an account of his own researches, a 

 resume of our previous knowledge of the natural history of 

 the country. It is thus not limited to a discussion of the 

 subject indicated by the title, but treats of the topograph- 

 ical and general features of the country, of its flora and 

 fauna, both marine and terrestrial, and of its mining, agri- 

 cultural, commercial and manufacturing interests. The 

 numerous maps and sketches which illustrate it, were drawn 

 by Professor Hartt himself, and the greater part of them 

 represent regions never before depicted. The volume closes 

 with a valuable appendix on the Botecudo Indians. 



In the year 1870, the same in which his book was issued, 

 Professor Hartt organized the largest of his own expeditions 

 from the United States. It was composed, beside himself, 

 of Professor Prentice and eleven students of Cornell Uni- 

 versity, His object in taking so many young men was to 

 give them thorough practical training, and to stimulate 

 them to undertake original work. He says in his report 

 of this expedition, that he did not expect to make scientists 

 of them all, but hoped that some of them might thus be in- 

 duced to accept this calling. The means for defraying the 

 e xpenses of the trip were contributed by several parties, 

 the most prominent of whom was Mi*. E. B. Morgan of Au- 

 rora, 1ST. Y. whose name has been given to this and the sub- 

 sequent expedition. 



Prof. Hartt determined on this occasion, to change his 

 field of research, and explore the Amazonas. Accordingly 

 he went with his party direct to Para, and in the neighbor-
