" Commercial Rose Culture, under glass and outdoors." By Eber 

 Holmes. 8vo., 165 pp. (Routledge, London, 1913.) 65. net. 



A book written chiefly for America, but containing a fund of 

 valuable information for British readers. In our opinion, however, 

 the price is much too high to find a ready sale in this country. It is 

 well indexed. 



" The Potato. A Compilation of Information from every avail- 

 able Source." By E. H. Grubb and W. S. Guilford. 8vo., 545 pp. 

 (Constable, London, 1913.) 8s. 6d. net. 



Mr. Grubb was special commissioner to Europe in potato investi- 

 gation for the United States Government, and Mr. Guilford is Director 

 of Agriculture, Sacramento, California, and the amount of information 

 they have compiled is enormous. The authors state that 25 per 

 cent, of the food of European and English-speaking people is potatos, 

 and that a 90-bushel potato crop contains 5400 lb. of food, and a 

 14-bushel wheat crop only 840 lb. Although everyone, rich or poor, 

 recognizes the great value of the potato as a food product, it will 

 be of much interest to quote from this excellent book what Dr. J. H. 

 Kellogg — the well-known authority on food — says : — " The belief is 

 quite general that the potato especially promotes fat-making, and 

 hence must be avoided by persons who have a tendency to obesity. 

 This is an error." And it will be of much interest to quote the follow- 

 ing table by Dr. Kellogg.

 1 J lb. of boiled potatos. 7 oz. bread.

' This table indicates that the potato is one of the most nourishing 

 foods, and it is also recommended by the authors for such diseases 

 as arteriosclerosis, gout, rheumatism, B right's disease, apoplexy, and 

 other maladies. There is much more information on the dietetic value 

 of the potato. Many products of commercial importance and value 

 are obtained from the potato, showing how important this crop is. 

 Cultivation, manuring, storing, combating and preventing disease, 

 the best varieties to grow, implements, &c, &c, are all exhaustively 

 dealt with, and although the book is written chiefly for American 

 readers, it should be read by every potato-grower and consumer in
