NOTES AND COMMENT 



Professor Elizabeth F. Fisher, of the department of Geologj^ and 

 Geography at Wellesley College, has prepared a brief volume entitled 

 Resources and Industries of the United States (Ginn and Company). 

 Although intended for use in secondary schools the book contains such 

 a complete and interesting account of our natural resources and the 

 industries that have grown out of them that it may well be read with 

 pleasure and profit by those who are old enough to have received much 

 drier instruction in geography. The plant and animal industries have 

 received their full share of attention and the book is well provided with 

 maps of rainfall, soils and crop distribution. 



The Macmillan Company have added to their Rural Science Series 

 a volume on Peach-Growing, by Mr. H. P. Gould, of the Bureau of 

 Plant Industry ($2.00). This is a very thorough and practical treat- 

 ment of the handling of tree, orchard and crop. Particular attention 

 is given to the selection of suitable orchard sites, the proper pruning at 

 different ages, and the control of diseases. The ill-informed consumer 

 of this fruit will be surprised to learn that 417 varieties are in common 

 cultivation in the United States. 



Dr. P. A. Rydberg announces the publication of a small volume con- 

 taining the keys from his Flora of the Rocky Mountains and Adjacent 

 Plains. This will find use as a handy field book and check list. The 

 plants of Colorado and adjacent states have now received such exhaus- 

 tive analj'sis by taxonomists that there are many cases in which it is 

 easier to make doubt-stilling determinations by the use of keys alone 

 than by the aid of manual and herbarium.
