aud fuel value of household measures (glassful, teaspoonful. tablespoonful. etc.) 

 of a number of common food materials. 



Dietary studies of a week's walking trip, II. L. Knight (Connecticut tStorr-s 

 8ta. Rpt. 1905, pp. I.'f3-163). — An account was kept of the food eaten by 2 young 

 men during 'a 7 days' walking trip. Each carried about 25 lbs. of luggage and 

 covered about 20 miles pei* day. 



Generally speaking the foods selected were those supplying nutritive material 

 in small bulk. One of the subjects obtained on an average 86 gm. protein and 

 .3,189 calories of energy per day and the other 56.6 gm. protein and 1.866 calories 

 of energy. 



A portable ration for soldiers in battle and on the march, L. L. Seaman 

 {Jour. Ainer. Mat. Assoc. 'iG {1906). Xo. 21. pp. 1G06-1(>OS). — An efficient 

 ration for soldiers in battle and on the march, it was pointed out. must fur- 

 nish proximate constituents in necessary proportion, must be easily digested 

 and palatable, and have a minimum waste. 



In the author's opinion, smoked beef is a valuable constituent of such a 

 ration as it is easily digested and palatable, may be eaten raw or cooked, and 

 does not become distasteful as soon as canned roast beef or corned beef. For 

 the carbohydrate constituent of the ration he suggests a mixture of 7 parts 

 rice and 3 parts barley meal, cooked, dried, and ground. Tea or coffee is 

 regarded as an essential part of the proposed ration, which also includes sugar, 

 chocolate, salt, and pepper. The calculated protein content is 93.20 gm. and 

 the energy value 2,672 calories. 



The nutritive requirements of the body, F. G. Benedict {Anier. Jour. 

 Physiol., 16 {1906), Xo. '/, pp. Ji09--'i37). — A general discussion of theories of 

 metabolism with special reference to recently published work of a number of 

 investigators. 



The author concludes that the evidence which has been presented is far from 

 sufficient to warrant the assertion that the amounts of protein ordinarily con- 

 sumed should be permanently and materially diminished, and believes that there 

 is evidence to show that permanent reductions are decidedly disadvantageous 

 and, indeed, not without possible danger. 



Basing his deductions upon the results obtained by the respiration calori- 

 meter (E.S. R., 15, p. 698) and the fact that the law of the conservation of 

 energy obtains with the animal body, the author points out that the energy 

 intake can be diminished only as the energy output or the muscular activity 

 is diminished. " These facts make any pi'oposition to lower food consumption 

 unaccompanied by decreased muscular activity impracticable." 



ANIMAL PRODTJCTION. 



Live stock {Quart. Rpt. W. Va. B<1. Agr., 1906, No. 3, pp. 132, figs. 33).— A 

 number of papers by different authors on the feeding and care of live stock, 

 diseases and their treatment, and related questions, and a summary of the laws 

 of West Virginia relating to infectious and contagions diseases of animals. 



Storage barn, sheds, feed lots, and other equipment for feeding experi- 

 mental cattle in carload lots, H. W. Mumford and E. S. Good {Illinois Sta. Bui. 

 110, pp. 303-32^, fi(/s. 6, d(/ins. 9). — The general plan of the experimental plant 

 used at the station for beef cattle feeding experiments is described and a de- 

 tailed description given of the construction of the storage barn, methods of pre- 

 paring and handling feed, and of the construction and operation of the feed lots, 

 the sheds and feed carrier system and of the corn crib and engine house, as well 

 as a general summary of the cost of the plant as a whole.
