TO THE READERS OF MUHLENBERGIA 
Owing to pressure of field work during the summer, as well 
as delay incident to beeoming established in a new place of resi- 
dence, mailing at pound rates had to be discontinued. Here- 
after no attempt will be made to issue this journal as a monthly, 
nor will twelve numbers constitute a volume. The present vol- 
ume will contain the usual number of pages, about 150. The 
time of completion will depend upon the promptness of contrib- 
utors or upon my own leisure for the preparation of articles. 
Revisions of genera, descriptions of new plants, and better 
still, the clearing up of doubtful points about old ones will al- 
ways be welcome.

This work is being pushed along rapidly, and I hope to 
complete it in April. Several valuable features not in former 
editions are found in this one, as family name at the top of the 
page, and citation of publication of families and genera. The 
book will be cloth bound, price $1.50 postpaid. Your subscrip- 
tion is solicited now, but payment may be made when the book 
is delivered. Your name now will save expense later, as the 
boek may be bound in the east, and mailing from the bindery 
will save freight charges.
