The number of phosphate properties (8 in 3 States) and of oil-shale properties (1) remained unchanged. Mineral prospecting during the year included 30 holes with aggregate of 14,957 feet, drilled for coal in Wyoming; 3 holes, 2,546 feet, drilled for sodium in California; and 5 holes, 5,331 feet, drilled for potash in New Mexico, as well as innumerable shallow holes and surface excavations in all publicland States. Safety and welfare conditions on mining properties under supervision remained generally satisfactory throughout the year, five coal properties receiving awards and one coal operator a trophy from the Joseph A. Holmes Safety Association, for outstanding accident-free accomplishment.

Indian lands.-On behalf of the Office of Indian Affairs technical supervision of mineral development was continued in 1935 on tribal and restricted allotted lands within the limits of numerous Indian reservations. Oil and gas supervision involved 4,812 leaseholds, 4,477 wells, and aggregate royalty and rental accruals of $338,164.63 for Indian beneficiaries in 7 States and in 27 different tribes and included royalty accounting for certain agencies, appraisals of bonus and royalty offers and of pollution damages, assistance to lessees of Indian land on operating problems and in the preparation of unit. plans of development, and assistance to agency officials and tribal councils on technical phases of leasehold development and administration. Mining supervision involved 36 lead and zinc leaseholds in the Quapaw Reservation, Okla., with aggregate royalty accruals of $216,557.04 during the year; 39 coal leaseholds involving Choctaw, Chickasaw, and Five Tribes land in Oklahoma, with aggregate production of 860,033 tons of coal and revenue accruals of $103,505.05: 1 asphalt lease involving segregated Choctaw and Chickasaw land, Oklahoma; 1 lime phosphate lease involving restricted allotted Five Tribes land, Oklahoma; and several scattered agency coal mines in the Western States. It included also special investigations of mining and marketing procedure under an asbestos leasehold in the San Carlos Reservation, Ariz., and of feasible methods of controlling coalmine fires affecting lands in the Crow and Fort Peck Reservations, Mont.

Naval petroleum reserves.-On behalf of the Navy Department supervision was continued during the year over operations for the production of oil and gas within Naval Petroleum Reserves Nos. 1 and 2, in California, and for the conservation of shut-in production within Naval Petroleum Reserve No. 3, in Wyoming. Production from the California reserves aggregated 3,415,743.46 barrels of petroleum, 3,633,889,000 cubic feet of natural gas, and 12,841,346.20 gallons of natural gasoline, and had an aggregate royalty value of $561,541.31.

PUBLIC WORKS PROJECTS

Under the supervision of conservation branch personnel aggregate expenditures of $535,872.05 were made during the fiscal year 1935 from funds allotted by the Public Works Administration in 1933, for field investigations and conservational work pertinent to branch functions. On four Federal projects $1,875.75 was expended for repairs and improvements at field camps maintained for branch employees at Taft, Calif., and Midwest, Wyo. On 11 projects $179,058.86 was expended for utilization surveys of power and storage resources of important streams in 11 public-land States. On 13 projects $354,934.44 was expended in 11 States in the plugging and abandonment or conditioning for use as a source of water of numerous wells drilled for oil and gas on public lands and thereafter improperly abandoned or merely deserted; in extinguishing or controlling coal-outcrop fires, and in filling, bulkheading, or otherwise safeguarding abandoned mine or prospect openings on public and Indian lands; and in surface studies of coal occurrence and subsurface studies of oil and gas occurrence in Indian lands in Oklahoma. Work was terminated under practically all these projects on or before June 30, 1935, by reason of the exhaustion of funds originally allotted. On a few projects unexpended balances were available and work was continued beyond the end of the fiscal year under authority of the President.
