510 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1919. 
The Yakima project in Washington includes a large system of 
storage reservoirs and two canal systems, known as the Sunnyside 
unit and the Tieton unit.. The project as a whole is very productive 
and prosperous, and strong pressure is being made to secure the con- 
struction of more storage, the extension of existing canal systems, 
and the construction of new canals from the Yakima River and its 
tributaries. The excellent results obtained show that this would be 
a wise development. The Yakima project as a whole is one of the 
foremost in general prosperity and in returning the cost of this 
construction. 
The Shoshone project in Wyoming is being gradually extended by 
additions to the canal and lateral systems on the north side of the 
Shoshone River. The drainage system, which has been largely com- 
pleted and has been very successful, is also being extended under 
contract with the water users in accordance with law. The lands 
are very productive and the project very prosperous. Preparations 
are being made for the construction of an additional unit on the 
south side of the Shoshone River, for which ample storage capacity 
has been provided in the Shoshone Reservoir. 
The value of the agricultural products exclusive of live stock pro- 
duced by the Government reclamation projects during the season of 
1919, amounting to nearly $89,000,000, has been over half of the net 
cost of construction of all of the projects during the last 17 years. 
On some of the projects the production has exceeded the total con- 
struction cost. The results in the extension of agriculture and of 
homemaking have justified the expectations of the advocates of this 
activity and argue strongly for its extension. 
CROPS. 
All agricultural statistics are now dominated bv the effects of the 
World War, and this is strikingly shown by a comparison of the 
table of irrigation and crop results presented herewith for 1919 with 
that for 1914 published in the Smithsonian Report for 1915 (p. 473). 
For all projects the crop report for 1919 shows a gross value of 
$89,000,000, or an average of $80 for each of the 1,113,000 acres 
cropped. Alfalfa continues as the great basic crop, occupying 38 
per cent of the crop area and furnishing nearly one-third of the total 
crop value. Cotton, while grown on only the four southernmost 
projects, brought in returns of over $20,000,000 in 1919. The follow- 
ing table presents statistics relating to crop production as collected 
by Government employees on the Reclamation Service projects. Fig-
