BUREAU OF PLANT INDUSTRY. 301 



Umatilla experiment farm. — The Umatilla experiment farm, of 

 which Mr. R. W. Allen is superintendent, includes 40 acres of land 

 located 2 miles north of Hermiston, Oreg., on the Umatilla project 

 of the Reclamation Service. This farm is operated under a coopera- 

 tive arrangement between this bureau and the Oregon Experiment 

 Station, by the terms of which the superintendent is directl}^ respon- 

 sible to the Oregon station, and the investigational work is planned 

 and carried out cooperatively between the two institutions. Experi- 

 ments with horticultural, fruit, and truck crops are the chief lines 

 of work, some attention being given to green-manure crops and 

 fertilizers. 



ScoTTSBLurr experiment farm. — The Scottsbluff experiment farm, 

 of which Mr. Fritz Knorr is superintendent, is located on the North 

 Platte project of the Reclamation Service, 6 miles east of the town 

 of Mitchell, Nebr. This farm is under the administrative supervi- 

 sion of the Office of Dry-Land Agriculture of this bureau, and the 

 experimental work so far as this office is concerned is limited to a 

 series of crop-rotation and tillage experiments occupying about 2-5 

 acres of land. During the past year this land has been devoted to a 

 grain crop with a view to getting it in proper condition for begin- 

 ning the rotation experiments in the season of 1912. 



Miscellaneous cooperati\'e investigational work. — In addition 

 to the field stations mentioned, this office is cooperating with the 

 North Dakota Agricultural Experiment Station at Williston, N. 

 Dak., where Mr. A. M. Hawley is employed to supervise the irrigated 

 crops at the Williston substation and to assist farmers on the project 

 in connection with their problems of irrigating crops. 



In connection with the investigations on the Klamath Marsh, it 

 has been found desirable to investigate the agricultural practices on 

 the reclaimed swamp lands in the delta of the San Joaquin and 

 Sacramento Rivers in California, and during the latter part of the 

 past fiscal year Mr. John P. Irish, jr., has been conducting these in- 

 vestigations from a point near Antioch, Cal. These investigations 

 have to do with subjugating the raw tule land and determining the 

 best methods of getting the land into crop and also in collecting data 

 with respect to air drainage as related to the production of crops 

 liable to damage by frost. 



Plans for future work. — With the discontinuance of the inves- 

 tigational work near Klamath Falls, Oreg., it is expected that an- 

 other field station will be started on one of the reclamation projects 

 during the coming fiscal year. This experiment farm will probably 

 be located at some point in the Pecos Valley of New Mexico, where 

 there are two small irrigation projects and where agricidtural 

 problems with reference to the production of cotton, alfalfa, and 

 orchard fruits have become acute, owing to the saline condition of 

 the soil and the ravages of the plant disease loiown as the cotton 

 root-rot, which affects not only cotton but alfalfa and many other 

 crop plants. 



Investigations so far made in the delta of the San Joaquin and 

 Sacramento Rivers in California indicate the importance of making 

 further investigations in that region, particularly to try a number
