INTRODUCTION. 
The Eastern Oregon Dry-Farming Substation * was established at 
Moro, Oreg., in 1909. The land was purchased and the buildings 
(fig. 1) erected with funds contributed by Sherman County. The 
expense of maintenance is borne jointly by the Oregon Agricultural 
Experiment Station and the Bureau of Plant Industry. 
A cooperative agreement between the Bureau of Plant Industry 
and the Oregon Agricultural Experiment Station specifies that "The 
objects of the cooperative investigations shall be (a) to improve the 
cereals of the Pacific coast region by introducing or producing better 
varieties than those now grown, especially with regard to drought 
resistance, yield, quality, earliness, etc.; (5) to determine the best 
methods of cultivation and crop rotation for grain production; and 
(c) to conduct such other experiments as may seem advisable for the 
accomplishment of the greatest possible good to the cereal interests 
of the State of Oregon." Full credit is given to the Oregon Agri- 
1 From the establishment of the Moro substation until November, 1911, Mr. H. J. C. Umberger was 
superintendent. In February, 1912, the writer was appointed superintendent.
