972 EXPERIMENT STATION RECORD. 



crickets, borers in trunks of trees, sucking insects on small plants, insects injurious 

 to stored products, seed insects, clothes moths, other household insects, museam 

 pests, and gophers. A brief account is also given of the effect of the vapor of carbon 

 bisulphid on plants, on the growth of crops, on the germination of seed, on food 

 stuffs and on fruits. An appendix to the bulletin, prepared by E. E. Ewell, dis- 

 cusses the amount of carbon bisulphid in a saturated atmosphere, the inflammability 

 and explosiveness of carbon bisulphid vapor with air, and the ignition temperature 

 of the vapor. 



Experience with, dust spray, A. A. Hinkley {Trans. Illinois Hort. Soc, n. ser., 

 35 {1901), pp. 219, 220). — The author has experimented for a number of years with 

 insecticides in a dry form in the place of sprays. While the results are not always 

 satisfactory it is believed that dry application may be, under certain circumstances, 

 cheaper and more effective than liquid spray. 



Insecticides and fungicides, J. K. Haywood ( T. *S'. Bepi. Agr., Farmers' Bui. 

 146, pp. 15). — A rejjort is made on the chemical composition and effectiveness of 

 Paris green, London purple, Green Arsenoid, Pink Arsenoid, White Arsenoid, 

 Paragrene, lead arsenate, Bug Death, Slug Shot, Black Death, Smith's Vermin Exter- 

 minator, P. D. Q., Instant Louse Killer, Lambert's Death to Lice, roach destroyers, 

 Bordeaux mixture. Grape Dust, Veltha, and Fibro Ferro Feeder. 



Report of the inspector of fumigation appliances, W. Lockhead {Toronto: 

 L. K. Cameron, 1902, pp. 16, figs. 5). — This is the third annual report by the author 

 on fumigation, and is occupied with a discussion of the Canadian regulations for 

 fumigation of nursery stock, methods of applying fumigation, necessary equipment 

 for this work, and the results of observations made in different parts of Canada. 

 Notes are given on fumigation in orchards, nurseries, greenhouses, flour mills, and 

 granaries. With regard to the possible injury of nursery stock from fumigation with 

 hydrocyanic-acid gas, the author believes that the most of such injury is due to 

 exposure of the roots of young trees for too long a time. With careful attention to 

 this point it is believed that the number of trees which fail to grow will be decidedly 

 reduced. 



Fumigation of imported plants, A. W. L. Hemming (Bui. Bot. Dept. Jamaica, 

 n. ser., 8 {1901), Xo. 11-12, pp. 184, 185).— A copy is given of a proclamation 

 announcing that hereafter plants, cuttings, buds, grafts, and packages or Ijoxes in 

 which such material is shipped shall be subject to a thorough process of fumigation 

 with hydrocyanic-acid gas before being admitted into Jamaica. 



FOODS— NUTRITION. 



Experiments on the metabolism of matter and energy in the human body, 

 1898-1900, W. 0. Atwater and F. G. Benedict {U. S. Dept. Agr., Office of Experi- 

 ment Stations Bui. 109, pp. i.^7).— The details of 13 experiments with man are 

 reported, in which the balance of income and outgo of nitrogen, carbon, and energy 

 was determined. These were made with the aid of the respiration calorimeter. 

 Experiments designed to test the accuracy of the apparatus were also made, in 

 which heat was generated in the respiration chamber electrically or by the combus- 

 tion of ethyl alcohol. In a number of experiments the subjects performed more or 

 less severe muscular work, in others there was as little muscular activity as practi- 

 cable. From these and earlier experiments (E. S. K., 11, p. 770) a number of general 

 deductions were drawn which have to do with such topics as the food materials sup- 

 plied and consumed, and the difference in demand of men at work and rest, the 

 elimination of water, carbon dioxid, and energy under different conditions of work 

 and rest. Especial interest attaches to the results which have to do with the meas-
