THE YOUNG PROFESSOR 183 



The College opened in September. The Grammar 

 School was now definitely separated from it. Baird's 

 duties included Chemistry, Natural Philosophy and 

 Zoology, twice a week each, before breakfast, for the 

 seniors; the juniors had four lectures a week in the after- 

 noon; a total of ten hours teaching weekly. 



On the 22nd of September he went to the meeting 

 in Philadelphia of the American Association of Geologists 

 and Naturalists; a precursor of the Association for the 

 Advancement of Science. Here he met many old friends 

 and had long conferences with Agassiz, who was over- 

 flowing with projects for the elucidation of the American 

 fauna and flora. At midnight of the 24th he left for 

 Carlisle 'accompanied by John LeConte. 



A few days later he had a visit from Professor Arnold 

 Guyot, who was studying the physical geography of the 

 Alleghenies. 



Agassiz contemplated a monograph of American 

 fishes, and wished for Baird's cooperation, which was 

 cordially given, and many fishes of Baird's collecting 

 were sent him. But this was too great an undertaking 

 in addition to Agassiz's other projects, and after some 

 years of delays and interruptions, the plan was allowed 

 to drop by mutual consent.

 DEAR BAIRD, 



If Bartlett and Welford of New York, or more especially the Rev. 

 R. W. Griswold, late of Phila., but now, as I believe, of New York, 

 can't tell you where to find the Periodicals you want, no man can. 

 I presume they are in the Library of Congress, and they must also 

 be to be found in the Boston Athenaeum and the public libraries in
