acter and public service, and throughout the scientific world for 
his fine abilities as a systematic botanist. His early fondness for 
botanical pursuits found a welcome Opportunity for gratification 
when a bronchial trouble drove him to Florida early in the year 
1858. . 
The tedium of an exile from home was altogether overcome 
when the pine woods about Magnolia, on the St. John’s River, 
were brightened by the flowers of early spring. It was the col- 
lection made at that time which was the foundation of his her- 
barium. Coming homeward by way of Savannah and Aiken, 
South Carolina, quite a large and varied collection was made. 
This was supplemented in August by a month’s botanizing in the 
Mountains of southwestern Virginia, especially about the cliffs of 
New River and the Salt Pond Mountain. A two months’ visit 
to Europe next opened some opportunities for exchange and cor- 
respondence. 
Up to August, 1860, efforts were mainly confined to obtain- 
ing specimens of the flora of Delaware, eastern Pennsylvania and the 
Pine barrens of New Jersey. At the date mentioned an extensive 
journey was made to New York, New England and Canada. 
The collections made at this time enabled him to exchange ex- 
tensively with botanists in the three Western States of Ohio, 
Indiana and Illinois, as well as with some in New England and 
New York. Among these may be mentioned Dr. Vasey, 
Messrs, Hall and Bebb, of Illinois; Watson, Hale and Lapham, 
of Wisconsin ; Sullivant, of Ohio, Dr. Sartwell and Judge Clinton, 
of New York, and several in New England. Prof. Porter and 
Dr. Trail] Green, of Pennsylvania, were also most esteemed corre- 
Spondents. 
About this time, also, Mr. Canby became acquainted with 
Drs. Gray, Torrey and Engelmann, and active correspondence 
and most valuable exchanges were the result. The immense stores 
of foreign botanical treasures which at that time came to Dr. 
Gray were freely shared with Mr. Canby. He also became a 
Purchaser of all valuable sets of American plants which he could 
find. The first of these were those of Dr. Parry and Messrs. 
Hall and Harbour, made in the then new country of Pike’s Peak 
and the other Colorado mountains and the plains at their base.
