be used ill the pn'paratiDii of cresol mixtures and cresol solutions. In gross disin- 

 fection of cattle cars it was found that, as a substitute for the i)rescri>)ed use of a 5 per 

 cent solution of crude carbolic acid, good results Avere obtai)ied from the use of a 3 

 ]>er cent aqueous si)lution of crude cresol and crude sulj)huric acid combined in the 

 jiropoition of 2:1. This solution is easily soluble in water and exercises a pro- 

 nounced disinfectant action. 



A 2^ per cent mixture of crude cresol and sulphuric acid destroyed glanders bacilli 

 within 1 to H minutes, hog cholera bacilli within from 1 to 2 minutes, and SUipJiylo- 

 rocrui^ pyogenes aureus in from 2 to 3 minutes. The disinfectant power of the other 

 substances mentioned above, all of which were used in a 5 per cent solution, stood in 

 the following order of effectiveness: C'rude carbolic acid, Sanatol, Bacillol, Cresolin, 

 and Cresapolin.

Heport of irrigation investigations for 1902, i>. Mead et al. {V. S. Dept. 

 Agr., Office of E.iperiment Stations Bui. 133, pip. 266, ph. 12, figs. 16). — Investigations 

 during 1902 similar to those of previous years (E. S. R., 14, ja. 713) are here reported 

 in part. The bulletin contains reports of special agents and observers as follows: 



Irrigation in Mountain Water District, Salt Lake County, Utah, by E. R. Morgan; 

 The Use of Water from tlie Wood Rivers, Idaho, by J. D. Stannard; Irrigation 

 Investigations on Sand Creek, Albany County, Wyo., by B. P. Fleming; Irrigation 

 in Washington, by O. L. Waller; Irrigation Investigations in Montana, 1902, by S. 

 Fortier; Irrigation Systems on Stony Creek, Cal., by W. T. Clarke and C. W. Landis; 

 Irrigation in the Black Hills, S. Dak., by A. B. Crane; Rice Irrigation in Louisiana 

 and Texas, by F. Bond; Third Progress Report on Silt Measurements, by J. C. 

 Nagle; Irrigation Experiments at the Missouri Experiment Station, 1)y H. J. Waters; 

 Irrigation in Wisconsin in 1902, by A. R. Whitson; Irrigation Investigations in New 

 Jersey, 1902, byE. B. Yoorhees; and The Use of Pumps for Irrigation in Hawaii, by 

 J. G. 'smith. 



These reports deal primarily with duty of water in irrigation. That of Mr. Morgan 

 on Jordan River and its tributaries shows the large losses from these streams and 

 discusses means of saving the water now lost, among which is the running of the 

 spring floods onto the lands along the upper reaches of the streams, thus storing 

 the Avater in the soil. Mr. Stannard' s report shows the large losses of water occur- 

 ring on the Wood Rivers and discusses the advisability of using special structures to 

 prevent these losses. Mr. Fleming's report deals with the use of the water of Sand 

 Creek for the production of forage, and with the effect of the diversion of the water 

 of the stream in Colorado on the supply to Wyoming users. The latter is of special 

 importance because of its bearing on the use of other interstate streams. 



Professor Waller's report calls attention especially to the damage being done by 

 excessive irrigation in parts of Washington. 



Professor Fortier' s report gives a large number of measurements of the duty of 

 water on special crops. 



The rei^ort on irrigation systems of Stony Creek, Cal., shows especially the profit 

 resulting from irrigation and diversification of crops as opposed to exclusive wheat 

 growing without irrigation, and calls attention to what is being done by farmers in 

 that region in storing storm water. Mr. Crane's report on irrigation in the Black 

 Hills shows that storing storm water is profitable in that region also. 



Mr. Bond's second report on irrigation of rice in Louisiana and Texas shows that 

 the demand for water for rice-growing is in many cases outrunning the supply both 

 from streams and from wells.
