IO — 
Tetrodonlium , one of the very rarest and least collected of our genera 
is described, but Leucodon and TJielia, two very common and easily recog- 
nized genera are omitted, as are also P hilonotis and Horn alia. Under 
P lagiothecium. P. Muellerianum alone is mentioned although a rare and 
difficult species, while the omnipresent P. denticulatum will be collected by 
almost every student on his first serious collecting trip. 
The colored plates of mosses, lichens and hepatics are scattered through- 
out the work with apparently little reference to the accompanying text, a 
most inconvenient arrangement for students; possibly it was not planned for 
such. 
Some of the common names given are interesting as well as original and 
the author evidently has not exhausted her talent for she is able to catt 
Funaria hygrometrica “ The Golden Cordmoss” and the “ Watermeasuring 
Cordmoss.” FTypnum uncinatum becomes the “ Hooked Boat hooked Moss,” 
H. splendens the “Glittering Feather Moss ” and H. triquetrum , the “ Tri- 
angular Woodreveler.” 
A figure of the seta and capsule of Mnium hornuin with calyptra 
clasped around the upper part of seta is described as a seta bearing a bract. 
Our readers are advised to spend an hour or two studying this book as 
many other points of interest will doubtless be discovered. 
It is greatly to be regretted that popular scientific books should be so 
often written by people who do not have a first-hand knowledge of the sub- 
ject, and that publishers with the resources of Doubleday, Page & Co. should 
issue such an inferior book when a first class book of this nature would have , 
been so helpful to the people whom the Bryologist and its editors are striv- 
ing to interest in the study of these plants. A. J. Grout,

SULLIVAN F MOSS CHAPTER ANNUAL REPORTS. 
Report of the President. 
To the Members of the Sullivant Moss Chapter: 
The Sullivant Moss Chapter now stands at the beginning of the second 
decade in its life. The membership is nearly seven times that of the first 
year; the field of work, from a correspondence study of common mosses, has 
broadened to include material in any way connected with the bryophytes or 
lichens of North America; the Bryologist has quadrupled in the number of 
pages, and advanced from a quarterly department in the Fern Bulletin to an 
independent bimonthly. Perhaps the Chapter was founded at the psycho- 
logical moment, doubtless the great increase of popular interest in nature 
has been a favoring factor, but be that as it may, the success of the Chapter 
has been due to the energy and self-sacrifice of the early members. 
Regarding the future, two things are to be urged upon the members. 
First, a more intensive study of geographical distribution, in which each 
member can help by the careful investigation of any locality. Secondly, an 
increase of the interest in the Exchange Department, The past year has 
seen the beginning of the distribution of specimens from foreign localities.
