98 * DEPARTMENTAL REPORTS. 



the controversy was most acute. The necessary field work was carried 

 on in May and June, 1900. It is confidently believed that the carry- 

 ing out of the recommendations that will follow this investigation will 

 result in protecting the industries of Arizona without destroying her 

 natural resources. 



PUBLICATIONS. 



The publications issued during the year, in addition to the reprints 

 of some of the earlier reports, are as follows : 



BULLETINS. 



No. 22, The Present Status of Rice Culture in the United States, by 

 S. A. Kuapj), issued December, 1899. This publication gives a descrip- 

 tion of the new system of rice culture, particularly' as now reaching 

 perfection in Louisiana and Texas, by which through a process of 

 controlling the water supply of the rice fields and thereby permitting 

 the use of machinery for plowing, harvesting, and other important 

 operations, the cost of production of rice has been so much reduced 

 that this country can compete successfuU}' with rice produced through 

 cheap hand labor in the Tropics. 



No. 23, Russian Cereals Adapted for Cultivation in the United 

 States, by Mark Alfred Carleton, issued February, 1900. This bulle- 

 tin is a detailed report, primarily intended for use of experimenters, 

 on the varieties of wheats secured by Mr. Carleton in Russia in 1898 

 and 1899. It gives full details of the characteristics of these wheats 

 in Russia and the conditions under which they are grown there, and 

 makes suggestions as to the places best suited to their trial in the 

 United States and the best methods of handling them. 



No. 24, The Germination of Seeds as Affected by Certain Chemical 

 Fertilizers, by Gilbert H. Hicks, issued April, 1900. This is a report 

 on certain experiments in which field and vegetable seeds of different 

 sorts were sown in soil in contact with fertilizers of different kinds. 

 The results of the experiments showed that some of these fertilizers 

 were distinctly injurious to the germination of seeds and in certain 

 cases would have destroyed almost the entire crop. The conclusion 

 drawn from the investigation is that these fertilizers should be applied 

 to the soil in such a way as not to come into direct contact with the 

 seeds. 



CIRCULARS. 



No. 18, Crimson Clover Seed, by A. J. Pieters, issued August, 1899. 

 The publication gives the result of an examination of a large number 

 of samples of crimson clover, and shows that the seed of this plant, 

 which has come into extensive use recently for forage and green fer- 

 tilizer, is found upon the market in an exceedingly variable condition. 

 Many samples are of high germination and fi-ee from weed seeds, but 

 some of the samples tested failed entirely to germinate and some of 

 them were badly adulterated. The result of the investigation was a 

 recommendation to farmers that before planting crimson clover seed 

 extensively a sample lot, drawn from what they proj)Osed to sow, 

 should be carefully . tested either by the farmer himself, b}^ some 

 experiment station, or by the Department of Agriculture. 



No. 19, Hop Cultivation in Bohemia, by David G. Fairchild, issued 

 November, 1899. This is an account, by one of the agricultural
