Postclsia, The Year Bool- of tlie Minnesota Seaside Sta- 

 tion, 1906. The Pioneer Press, St. Paul, Minn. The writer 

 has the good fortune to be among those who have an in- 

 timate acquaintance with the conditions of life upon our 

 Pacific northwest coast, the richness and variety of which chal- 

 lenges the interest of every student of biology, be he botanist or 

 zoologist. It is quite evident that the two volumes of Postelsia, 

 the first of which was issued four years ago, are the products of 

 this interest, and the enthusiasm begotten of it, in those who have 

 gone year by year from the University of Minnesota to their 

 far-off seaside station on Vancouver Island, and we are glad to 

 see that the day is not yet past when such interest may be allowed 

 more latitude of expression than that of fonnal statement in 

 formal journals. The Postelsia is a unique publication, but it 

 must be forgiven this fault in view of the evident worth of the 

 matter therein. The larger number of the papers deal with the 

 vegetation of the region, and are either distributional or taxo- 

 nomic; in one a new kelp, Renfrewia parvula Briggs, is de- 

 scribed; another is an ecological study of the tide pools; while 

 the last is a geological paper dealing with the feature of the sta- 

 tion grounds. One may get from the volume, which is ])lenti- 

 fully illustrated with halftones, an excellent general notion of 

 the vegetation of the southeni ]iart of Vancoiiver Island, a local- 

 ity which is typical of the whole northwest coast. 



Dr. C. F. Bal-er, lately chief of the Botanical Department 

 of the Agricultural Experiment Station of Cuba, has been 

 elected professor of botany in P(imona College, Claremont, Cal- 

 ifornia. Professor Baker has already served as an instructor 

 for a year in this institution. It is reported that Dr. Baker's 

 extensive collection of herbarium material passes into the con- 

 trol of the department.
