articles relate to animal ecology. The new journal compares favorably in 
general appearance and typography with the Plant World, which it replaces, 
and seems likely to reflect credit upon its editor, with his associated editorial 
board, as well as upon the Ecological Society of America.—GrEo. D. FULLER. 
arine algae of Beaufort.—Hovr’ has published a very full account of 
the marine algae of the region adjacent to the biological station of the Bureau 
of Fisheries at Beaufort, N.C. The ecological data are fully covered in a 
general description of the region, the variation in the floras of different parts 
of it, the conditions of temperature, light, salt content of water, turbidity, 
water movements, and habitats, and finally the regional, seasonal, vertical, 
and horizontal distribution of algae. Methods for collecting and preserving 
algae are given, and also some account of their economic uses. In the classi- 
fication and description of the algae of the region, 128 species are included, 
distributed as follows: Myxophyceae 10, Chlorophyceae 23, Phaeophyceae 25, 
and Rhodophyceae 70. An artificial key to genera and a full bibliography 
are also provided. 
The Bureau of Fisheries is to be commended for such a publication. It 
feels called upon to give the following explanation: ‘‘The question may be 
asked, Why should the Bureau of Fisheries be interested in marine algae? 
Excluding purely scientific considerations, there may be recalled the well 
known fact that all animals depend on plants for food, and this is as true of 
water animals as of land animals.” —J. M. C. 
Ecology of algae.—In the sandhill region of western Nebraska are numer- 
ous small lakes, all comparatively shallow, and varying much in alkalinity. 
ANDERSEN and WALKER’ have studied the algal vegetation of several of these 
and endeavored to measure the controlling factors. They found the means 
available for measuring light were entirely insufficient and resulted in nothing 
but the crudest approximations. The mineral and gas content of the water, 
however, showed a direct relation to the algal flora. A rather definite season- 
able periodicity was manifest, and in the extensive lists of species this rela- 
tionship is indicated.—Gro. D. FULLER. 
Montane plants of the southern Rockies.—Continuing his studies of the 
flora of the Rockies, RypBERG® has analyzed the plant population of the 
southern portion of the range. The formations distinguished are the pine 
forest, spruce forest, sen and poplar groves, erent onecoee swamps, copses, 
and sage brush. —Geo. D. FULLER.
