144 THE PLANT WORLD. 



Professor and Mrs. V. M. Spalding have gone to Witcli 

 Creek, California, to carry on some botanical work on distribu- 

 tion during the summer. A portion of the time will be devoted 

 to the observations planned bv the Desert Laboratory on the veg- 

 etation of the Salton Sea region. 



Mr. C. E. Blumer has gone to the Chiricahua Mountains in 

 Arizona to carry forward liis work on the flora of that region, 

 begun in 1906. 



Bergen and Daris' Laboralorij and Field Manaal of Bot- 

 any, just published l)y Giun & Co., is destined to accompany the 

 "Principles of Botany," by the same authors, or, for shorter and 

 more elementary courses, Bergen's "Elements," or his "Founda- 

 tions" of Botany. Tt is pleasing to come upon a thoroughly 

 scientific manual which approaches botany, as does this one, 

 through the old, bnt always practical and satisfactory, gate-way 

 of familiar seed-plants, the germination of their seeds and the 

 development of their seedlings. Following sixty-nine pages de- 

 voted to the structure and ]ihysiology of seed-plants, are eiglity- 

 four pages giving the usual morphological series of type studies, 

 from the flagellates to the angiosperms. Then follow twelve 

 iniiics on Ecologv, i>iviug an insight into this branch of the sci- 

 ence. Chapters on Microtechnique, (^ilture ^Methods, ^Material, 

 etc., together with a bibliogra])hy, a glossary, and a workable in- 

 dex, complete a volume which is Iw far the best of its kind yet 

 ])roduc('(l in America. B. E. L. 



To the Eelectlc Series of readings for children, published by 

 the .\merican Book Co., are now added two books of nature 

 study : The Trail to the Woods, by (dareuce Hawkes, and Xature 

 Studies- on the Farm, by Charles A. Kefter. The former com- 

 prises a series of stories of wild animal life, and deals with a 

 number of the beasts, fish and fowl most apt to be already more 

 or less familiar to the average boy or girl. The latter is a treat- 

 ment for children of some of the more salient facts and principles 

 of agriculture and of the physiologv of ])lauts. Botli volumes 

 contain uumcrous illustrations.
