27. Hillman, F. H., and Helen M. Henry. Identification of seed of Italian alfalfa 

 and red clover. Seed World 7 3 : 15. 1920. — Studies made in the Federal Seed Laboratory of 

 the United States Department of Agriculture indicated that it is possible for the expert seed 

 analyst to identify with reasonable certainty alfalfa and red clover seed grown in Italy, 

 when the seed is represented by samples of sufficient size. The six kinds of incidental seeds 

 peculiar to the Italian strains constitute the basis of identification, namely: Heelysarum 

 coronariwn, Galega sp., probably G. officinalis, Trifolium supinum, Cephalaria transylvanica 

 of the Dipsacaceae, a species of Phalaris closely allied to Phalaris canariensis, and an un- 

 determined species of Valerianella very similar to V. dentata. — M. T. Munn.

 Pt. 1. Obtaining of cattle feed from the farm. Pt. 2. Forest, meadow and moor as sources of 

 cattle feed. The use of aquatic and swamp plants as cattle feed, etc.] Stuttgart, 1917-1918. — 

 The first part of Hiltner's book was written in the spring of 1917 and is perhaps best described 

 to American agronomists by saying that it is comparable in subject-matter and manner of 

 treatment to a high-grade station or Department bulletin on forage and fodder crops, with 

 special reference to war conditions. The 84 pages of this publication are devoted to a discus- 

 sion of forage products grown on the fields, both cultivated plants and weeds. Under each 

 of the more important crops the author gives the composition in terms of the percentage of 

 protein, fat, and nitrogen-free extract, discusses methods of culture, fertilizers, and the best 

 methods of utilizing the feed, whether green, ensiled, or as dried feed. In the second part, 

 written in the spring of 1918, the author discusses fodder that may be secured from woodland, 

 moorland, or other waste lands, water and swamp plants, feeds from the waste of gardens, 

 orchards, vineyards, and hop fields. And finally, in an appendix the author discusses the 

 methods of treating straw to make it a desirable feed. — In 1913 Germany imported a total 

 of one million tons (of 1000 kg. each) of food stuffs for farm animals. This had a value of 43.3 

 marks per head of large live stock (Hauptgrossvieh), while the value of food imported 

 for human consumption was valued at 26.66 marks per capita. A large part of the 

 imports too consisted of protein and fat-rich foods. The object of Hiltner, therefore, is to 

 point out how German farmers may increase their output of forage by producing more per 

 acre or by utilizing weeds and other plants not commonly used, and waste products. Much 

 of the advice given the German farmer would be inapplicable to American conditions because 

 of the considerable amount of hand labor involved. The saving of waste products by labor- 

 ious processes may be necessary under certain conditions, but would certainly not appeal 

 to American farmers. — The author frankly points out that while many plants not commonly 

 used may be fed, these will in most cases serve only as roughage, and have not the protein or 

 fat content to make them valuable as substitutes for imported concentrates. — The discussion 

 in part I falls under five heads: 1. Legumes and clovers. 2. Potatoes. 3. Sugar beets, 

 mangels, swedes, carrots. 4. Miscellaneous forage plants. 5. Weeds. — The cultivation of 

 legumes is urged but nothing new is brought out. Most emphasis is placed on potatoes and 

 sugar beets. Before the war 12 per cent of the arable land in Germany was devoted to pota-
