An exchange club for Thallophytes.—The following official com- 
_ munication was received too late for the April number. It was sent in 
response to a suggestion by the editors of this journal that the arrange- 
____ ments being made to establish a botanical exchange club might well be 
a extended to include the lower orders of plants, or else a similar but inde- 
pendent organization might be effected for that purpose, greatly to the 
advantage and convenience of many botanists: 
IRS: I am authorized by the Commissioner of Agriculture to say 
that the same arrangements made with the committee of the A. Ay Aw®: 
Botanical Club for facilitating exchanges of plants may be extended to 
include the thallophytes. : 
shall take pleasure in carrying out the purposes intended.

As the letter shows, Commissioner Colman, with much liberality,im- 
of the several classes of collectors, and Prof. Scribner kindly offers to un- 
dertake the same supervision of the thallophytes that Dr. Vasey gives to 
the higher plants. It now remains with the botanists of the country to- 
arrange and perfect plans to put the system of exchanges into successful 
Operation.
