It is not considered safe to use any Paris green on the peach trees without the 

 addition of lime. The difference in the effect produced by Paris green when 

 sprayed with and without the addition of lime is so great that the use of lime is 

 recommended in all cases.

Fumigation practice, C. W. Woodworth (California Sta. Give. 11, pp. 27, figs. 

 2Jf). — This circular contains in a slightly revised and condensed form the material 

 presented in Bulletin 122 of the California Station (E. S. R., 11, pp. 64, 65). 



Gasolene as a remedy against enemies of the squash, cucumber, and 

 pumpkin, F. W. Card and A. E. Stene (Rhode Island Sta. Rj)t. 1908, p. 216).— Gaso- 

 lene was tested as a remedy for the squash borer and the larv?e of the striped beetle. 

 Holes were made in the ground about 7 in. deep, and from 2 to 4 teaspoonfuls of 

 gasolene were poured in each hole. The method proved wholly ineffective against 

 these insects. 



Seed and soil treatment and spray calendar, W. J. Green* and A. D. Selby 

 (Ohio Sta. Bui. 147. pp. 41-53). — This is a revised edition of Bulletin No. 102 of the 

 same station (E. S. R., 11, p. 274). The information contained in the bulletin is 

 also published in a folio form. 



Foul brood (Jour. Dept. Ayr. and Tech. Instr. Ireland, 4 (1904), No. 4, pp. 722-729, 

 •ph. 3). — The sources of infection, symptoms, and treatment of this disease are 

 described in detail. In preventing foul brood it is recommended that hives be placed 

 on dry stands, that the hives be kept clean and tight, that old combs be rejected 

 and old colonies strengthened by combination, and that pieces of naphthalin be 

 kept in each hive. 



FOODS— NUTRITION. 



Breakfast foods, F. "W. Robison (Michigan Sta. Bui. 211, pp. 25, charts 2). — The 

 principles of nutrition are discussed and the results of analyses of 48 samples of 

 breakfast foods and similar goods are reported. In addition to the usual constitu- 

 ents the insoluble starch and the materials soluble in water (ash, protein, sucrose, 

 dextrin, and soluble starch) were determined. The insoluble starch varied from 

 17.59 to 77.13 per cent, being over 40 per cent in all but 8 cases. The total soluble 

 material ranged from 2.75 to 55.15 per cent, and the dextrin from 1.02 to 25.50 per 

 cent. The author's conclusions follow: 



"The breakfast foods are legitimate and valuable foods. 



- ' Predigestion [i. e., rendering insoluble material soluble by malting or other 

 treatment] has been carried on in the majority of them to a limited degree only. 

 The price for which they are sold is as a rule excessive and not in keeping with 

 their nutritive values. 



"They contain as a rule considerable fiber, which while probably rendering them 

 less digestible at the same time may render them more wholesome to the average 

 person. 



"The claims made for many of them are not warranted by the facts. The claim 

 that they are far more nutritious than the wheat and grains from which they are 

 made is not substantiated. They are palatable as a rule and pleasing to the eye. 



"The digestibility of these products as compared with highly milled foods, while 

 probably favorable to the latter, does not give due credit to the former, because of 

 the healthful influence of the fiber and mineral matter in the breakfast foods. 



"Rolled oats or oatmeal as a source of protein and of fuel is ahead of the wheat 

 preparations, excepting of course the special gluten foods, which are manifestly in a 

 different class."
