LINES OF WORK. 



The work of the Colorado Station for the past year has been similar 

 to that of former years, including studies of irrigation problems; 

 variety tests of wheat and oats, for different altitudes; feeding experi- 

 ments with Belgian hares, lambs, and swine; horticultural, entomolog- 

 ical, and chemical investigations; and meteorological observations. 

 The work of the irrigation engineer has included investigations on the 

 use of water for irrigation as applied on different farms under varying 

 conditions, and measurements of seepage, the latter for the special 

 purpose of determining the important relation between the area irri- 

 gated, or the amount of water applied, and the amount returned. 

 These measurements are made on the Platte, the Arkansas, the Rio 

 Grande, and their tributaries, and have been extended recently some 

 40 miles above the section formerly measured on the Rio Grande. 

 Measurements are also being made of losses from ditches, principally 

 in the Cache la Poudre and Arkansas valleys, and the best means for 

 economizing water are being studied. The principal horticultural 

 work is the study of a disease of peas and the continuation of variety 

 tests of native plums and small fruits. The entomologist is investi- 

 gating the ravages of the codling moth, peach twig and apple twig 

 borers, various leaf rollers, cutworms on alfalfa, grasshoppers, and 

 insects working on sugar beets and cantaloupes, and is continuing tests 

 of comb foundations and studies of foul brood. The chemical work 

 includes analysis of water used in irrigation; studies of means for 

 extracting beeswax from old combs; sugar-beet investigations; soil
