Philadelphia in 1861, where he long held a prominent position in 
the extensive and well-known car wheel works of A. Whitney & 
Sons, with the members of which his marriage connected him. 
His allegiance was necessarily transferred from the Lyceum to the 
Academy, of which he soon became a life member, and was gradu- 
ally advanced to many of its most important and laborious offices. 
Thus, in 1870, he became a member of its Council and was also 
made Conservator of its Botanical Section, the latter a most im- 
portant office as it placed the various and very important herbaria 
in his charge. He was Corresponding Secretary of the Concho- 
logical Section in 1879, and after having been long a member of 
its Publication Committee was made its Chairman in 1891. It 
will thus be seen how important his services were to this institu- 
tion and how great the esteem in which his good sense and active 
exertions as well as his wise and thoughtful counsel were held by 
his associates. But beyond all this, and especially after his retire- 
ment from business cares in 1885, he accomplished a great work 
which no one else connected with the Academy had time to do and 
for which, indeed, no one was better fitted than he. When he 
took charge he found four distinct herbaria as follows: that of Dr. 
C. W. Short; that of Schweinitz, composed principally of Fungi, 
very many of them types; the General Herbarium, and the North 
American Herbarium, the latter of which is of the utmost value, 
not only because of its size and completeness, but also because it 
contains a large number of the type specimens of Nuttall, Pursh 
and others of early botanists of this country. The specimens in 
these were loose in sheets of paper, very often those of more than 
one collector huddled in together, with the labels but loosely 
attached to the specimens. With great care and good judgment, 
and an indefatigable energy, he brought order out of this con- 
fusion, so that at last he had got the greater and more-valuable 
parts of the herbaria arranged and mounted and properly cata- 
logued. Nor did his benefations end with this, for he purchased 
all valuable sets of plants and bestowed them upon the Academy. 
The tender and appreciative minute adopted by it and hereafter 
appended is but a fitting testimony to his usefulness and unselfish 
devotion.
