national in all its bearings.”” Then drawing an analogy from the 
city boards of health and their quarantine laws, he urges “‘the 
establishment of an agricultural board of health in every district, 
invested with ample powers and resources to maintain a healthy 
agriculture,” and adds: “‘It may be necessary to provide inspec- 
tion of seeds before they are allowed to be sowed.” These sugges- 
‘tions are in part carried out at the present time by our Federal 
Horticultural Board’ and by state seed inspection laws. It is 
possible that we may in time arrive at the condition finally urged 
by Michener, who suggests that in case a farmer does not properly 
care for his fields “‘it may be necessary to remove him tem- 
porarily from his premises, and to place them in the hands of an 
agent until they are fully cleansed from the infection.” 
PHILADELPHIA ACADEMY OF SCIENCES 
Michener was elected a correspondent of the Academy of 
Natural Sciences, Philadelphia, in 1840, and throughout his life 
it formed his chief contact with the scientific world. While 
Michener’s name appears but rarely in the records, his services 
to the Academy were considerable and his interest great. 
The writers have already called attention to the fact that the 
mounted portion of Schweinitz’s collection of fungi at the Phila- 
delphia Academy is mounted in exactly the same manner as are 
the specimens in Dr. Michener’s herbarium (11). It is now 
evident that the method of arrangement was original with Dr. 
Michener. For in the files of the Academy is the following letter 
written on the outer surface of a brown paper folder indentical 
in size and kind of paper with those in the Michener herbarium, 
and having pinned on the inner side three of the small square 
sheets of ruled paper like those on which the fungi are pasted in 
his herbarium (11, pl.3,4). This sheet was evidently intended as 
a sample, and Michener thriftily utilized the outside of the sample 
for his letter. ;

Dear Doctor, 
I have inclosed a sheet of my paper with a specimen of labels, 
for thy examination. —From which thee will vary the size of the sheet; and the size
