toes and 40 per cent of the crop was fed to animals. Besides the tubers the herbage, cut just 

 as the tubers ripen can be used as hay or ensilage. Miscellaneous information is given on 

 various minor forage plants and weeds with a view to the more general utilization of every- 

 thing edible. — In part II food stuffs to be secured from trees, shrubs, water and swamp plants 

 and from various water products are discussed. — The use of forest tree foliage and twigs is 

 especially urged and there is an alphabetical list of species under which are given the essential 

 items of information for each species. — Wood, chemically treated, was being used in 1918 but 

 apparently not as yet very largely or successfully. The author refers hopefully however to 

 many plans underway. In an appendix the treatment of straw with caustic soda is dis- 

 cussed. — A. J. Pieters.

 Bull. 15: 360-368. 1919. — A questionnaire sent to flour mills in North Dakota secured whole- 

 sale flour prices at a date when federal supervision of milling was in force and thereafter. 

 Comparative profits on flour and mill feeds are discussed. — L. R. Waldron.

 the industrial uses of peat are discussed in the light of post-war conditions. — Orion L. Clark.

 This is essentially a handy compendium of information regarding the various feeds on the 

 German market in 1918 or which might be produced by the farmer. In general it covers the 

 same ground as Hiltner but without the cultural directions and with the data on the compo- 

 sition of the various substances more conveniently arranged. In many cases only the trade 

 name and chemical composition of the substance is given. References to sources of chemical 

 data are given, and as a rule there are one or two, rarely three analyses. — Besides prepared 

 feeds there are data on all sorts of major and minor forage crops, trees and shrubs, weeds, 

 swamp plants, vegetable and animal wastes. Preparations from chemically treated wood and 

 straw are discussed and some directions given. — A. J. Pieters.

 sativa). [After-ripening and germination of rice seeds in various stages of maturity.] Ber. 

 Ohara Inst. Landw. Forsch. 1: 361-387. 1918. — Grains in the "milk stage" are capable of 

 germination, though the percentage germinating is small. However, if they are kept 15 

 days in dry storage, or 30 days in moist storage, they will germinate well. The "yellow- 

 ripe" grains germinate sparingly, but if kept for 3 months they will germinate as well as fully 

 ripe grains. The "fully-ripe" grains germinate at once, but germinate better if kept for a 

 month after harvesting. The "dead-ripe" grains germinate immediately after harvesting 

 and need no after ripening. — The after-ripening process is rapidly accomplished, if the rice 

 seeds are kept in a dry condition, but is delayed under moist conditions. Seeds ripened 

 under moist conditions germinate better, however, than those ripened under dry conditions. 

 It is unnecessary to keep the seeds in the panicles. — The germination of freshly harvested,
