THE DRY FARMING CONGRESS.

The work is so arranged to allow of an elaborate and accurate sys- 

 tem of cross-clieQldng, not only between plats and rotation of a single 

 station, but also between those of all the stations. 



In this way, practically all of the various methods of agricultural 

 practice in common use in the area, as well as these which have been 

 advocated and advertised as "new" are being thoroughly tested under 

 rigidly scientific methods, which should give thoroughly reliable quan- 

 titive values for each and every practice. 



Experiment Stations. 



We want to carry on these investigations long enough so we can 

 find, in a given locality, which practice will result in the best way on 

 an average through a long term of years. Our co-operative stations ara 

 located at Judith Basin, Montana; Dickinson and Edgeley, North Dakota; 

 North Platte, Nebraska; Hays and Garden City, Kansas. The inde- 

 pendent stations are located at Belle Fourche, South Dakota; Akron, 

 Colorado; Dalhart and Amai'illo, Texas. 



All of these stations are equipped with necessary tools, implements, 

 etc. for carrying on the field work, weighing and measuring the results. 

 Each station also has a full set of the instruments for measuring the 

 various meteoroligioal and physical factors. This part of the work is 

 under the supervision of Dr. L. J. Briggs, Physicist of the Bureau of 

 Plant Industry. At nearly all the stations work in cereal investigations 

 is being conducted by Prof. W. M. Jardine, Assistant Cerealist, Bureau 

 of Plant Industry. At some of the stations investigations in soil bac- 

 teriology have been carried on. 



8. DRY LAND GRAINS. 



By Prof. W. M. Jardine, Assistant cerealist, Department of Agricul- 

 ture, Washington, D. C. An abstract giving conclusions at close of his 

 address at Salt Lake Congress. 



I would like to give you a concrete conception of cereal production 

 as I vi'ew it 



Seed Breeding. 



I. Prom a disorganized condition, the production of cereals, espe- 

 cially wheat, has, through the introduction of foreign varieties of grain, 

 elimination of inferior types and a uniform system of grain growing, be- 

 come concentrated into four belts, more or less distinct and with one 

 exception characterized by the production of one or two standard va- 

 rieties especially adapted. 



Durum Wheat. 



II. That the durum wheats have proved themselves especially valua- 

 ble as spring type^, particularly as regards drouth and rust resistance 

 and that they will ultimately become the leading spring type.
