bers to the exsiccatae issued by Dr. Grout and Prof. Holzinger. In addition 
to this, however, it is increasingly evident from the letters of individual 
members, that a spirit of service is rapidly developing which augurs well for 
the future prosperity of the Chapter. 
The character of the offerings made in each issue of the Bryologist also 
deserves notice. During the past year there has been a gratifying increase 
in the number of rarer species offered. Every effort should be made to 
develope this department, not only for the value of the exchanges, but also 
because familiarity with. the appearance of rarer species undoubtedly leads 
to their detection in new localities. Members are urged when making offer- 
ings to be especially careful to specify the locality in which the specimens 
were collected. This practice enables those desiring specimens to chose 
offerings with greater ease, and prevent the receipt of the same species 
from localities already well represented in the applicant’s herbarium. The 
same species, moreover, often varies greatly in exchange value and in appear- 
ance, according to whether it comes from the .center of its known range or 
from a point near the limit. It is but courteous, therefore, that those mak- 
ing the offerings give some indication of the origin of the specimens. 
In my last report I mentioned the value of local flora work. While it is 
perhaps too soon to attempt any correlation of the distribution of mosses, 
lichens, or hepatics, with the underlying geological formation, yet the vari- 
ous local lists which have recently been published in the Bryologist, or 
notes such as that of Prof. Holzinger upon Grimmia glauca , with its men- 
tion of the remarkable features of the driftless area in Minnesota, lay found- 
ations upon which future workers will build. 
Finally, I wish to extend my sincere thanks to the members for their 
ready response to the circular letter sent out in June, and for their willing 
co-operation in making the third meeting of the Chapter a success. 
Respectfully submitted, 
Edward B. Chamberlain, 
President. 
REPORT OF THE SECRETARY. 
During the past year the Chapter has added twenty-three to its member- 
ship, ten have withdrawn, four died, giving a total of one hundred and sixty- 
five as listed in this number of the Bryologist. 
The herbarium has been increased by a large number of interesting 
additions. The Rev. Mr. Watts, of Young, South Australia, has sent us a 
large collection of mosses from his locality. Mr. Nickolson, of England, has 
sent us specimens from England and the Continent. Mr. Haydock sends 
many from the White Mountains: Mr. Foster a lot from Wallowa, Oregon, 
with notes on the geological formation. Dr. Grout, Rev. Dupret, Cannon 
Lett of Ireland, Prof. Bonser of Spokane, Dr. Breckle of North Dakota, 
Miss Miller of Washington, D. C., and many others are contributors. 
Thro the courtesy of Prof. Frye, of the University of Washington, 
many of our Pacific slope mosses have been obtained.
