46 SPENCER FULLERTON BAIRD 
These letters were the first of a series extending over 
more than seven years, in which the friendliness of the

not found in Professor Deane’s collection will be inserted 
in their appropriate places. 
It is quite surprising in looking over the journal, and

The college examinations took place in June, 1840. 
On the ninth of the month he received his degree of A.B.

Having graduated, the vacation months were spent in 
reading, study, excursions on foot and in the saddle, with
