ANNUAL, REPORT SMITHSONIAN INSTITUTION, 1919. 
area for which the service can supply water, the increase in areas 
actually irrigated and cropped, and the increase in the value of crop 
produced. This progressive increase is shown in the following table, 
which gives statistics only for those areas covered by crop census, 
excluding practically all those additional areas which are served from 
the works of the Reclamation Service under Warren Act contracts 
and from which, crop statistics were not obtainable. It is estimated 
that, including these areas, the crop value in 1919 amounted to 
$150,000,000 or over.

The statistics given in the above table do not, however, tell the 
whole story. The easy terms of repayment granted by the Govern- 
ment and the high prices received for their products have combined 
with the other favorable conditions and with the industry of the 
people to produce a condition of prosperity beyond the indications 
of the bare statistics. 
No new projects have been undertaken within the past year, as 
there have been no funds available for this purpose. The gradual 
decline in the receipts from the sales of public lands, due largely 
to the wholesale disposal of these lands under the operation of the 
640-acre homestead act, has naturally greatly restricted the opera- 
tions under the reclamation act. The small payments provided by 
law from the irrigated lands have kept the returns from the con- 
structed projects to a low point. It is now necessary, under the 
provisions of existing law, to set aside $1,000,000 per annum from 
these receipts to repay the advances to the reclamation fund which 
were provided by the act of 1910, known as the " bond loan." It has 
been possible on this account only slightly to extend the irrigated 
area by some extension of canal systems and to take care of water- 
logged conditions as they have arisen on some of the projects. 
CONSTRUCTION RESULTS. 
In spite of the adverse labor conditions and the absence of oppor- 
tunity for the undertaking of new projects, it is noteworthy that
