wish to see the author's full alphabetical list, which can be obtained by apply- 
ing to the author at 360 Lenox Road, Brooklyn, N. Y. For the purpose of 
stimulating field workers further to turn their attention toward Dr. Grout’s 
needs, for he doubtless proposes to continue this series, and also to show 
rather definitely the geographical gaps in which new collectors are desired 
to arise, I have compiled the following tabulation showing the distribution of 
States and collectors represented : 
Maine — Miss Alice L. Crockett. 
Vermont— Mrs. J. B. Clapp. 
Vermont, New Hampshire, New York — A. J. Grout. 
Vicinity of Catskill Mountain House— C. F. Austin and E. A. Rau. 
New York — B. D. Gilbert, J. W. Martens. 
Pennsylvania— D. A. Burnett. 
Connecticut— Mrs. J. D. Lowe. 
Massachusetts— Miss Cora H. Clarke, Mr. Walter Gerritson, Mr. J. W. 
Huntington. 
Maryland— Wm. R. Maxon. 
District of Columbia — Miss Mary F. Miller 
South Carolina — Prof. H. A. Green. 
Georgia — Mrs. A. P. Taylor. 
Florida — S. Rapp. 
Missouri— N. L. T. Nelson. 
Illinois— L. M. Umbach, F. E. McDonald. 
Wisconsin — L. S. Cheney, J. M. Holzinger. 
Colorado — J. M. Holzinger and C. F. Baker. (This should be the read- 
ing on the label No. 176.) 
Montana — J. M. Holzinger and J B. Blake. 
California — M. A. Howe, M. S. Baker and F. P. Nutting. 
Oregon — A. S. Foster. 
Washington — J. W. Bailey, A. S. Foster, T. C. Frye. J. B. Flett. 
British Columbia — J. W. Bailey, E. Wilson. 
Canada — H. Dupret, J. Macoun. 
This list shows that about thirty-four collectors, working in twenty-two 
states and provinces have co-operated with the author, Dr. Grout, in achiev- 
ing this notable result. Though much has been accomplished, a moment’s 
consideration of the great tracts still awaiting even cursory exploration will 
convince any one that the half is not yet done. Less than half the number 
of states of the Union, and only a small corner of the vast Canadian region, 
to say nothing of Alaska. The choicest, rarest things are yet waiting to be 
discovered, among them doubtless scores of species still undescribed. It is 
safe to state that one lifetime, even with five times the support so generously 
given to the author, will hardly suffice to approximate the completion of this 
task. Yet whatever fraction of it is done is a distinct gain for bryology; for 
it is sure to make possible a uniform understanding of critical and little 
known species by furnishing to most widely separated investigators uni- 
formly identical material recognized as typical by the most competent stu-
