The occupancy and use of National Forest land or resources under a special use permit (except those given free of charge) are conditioned upon the payment of a charge and are based upon certain rates. Agricultural use of land is given to permittees at a charge of from 25 cents to $1.00 an acre. Not over 160 acres are allowed to any one permittee. Cabins cost from $3.00 to $5.00; hay cutting from 20 to 50 cents an acre; hotels and roadhouses from $10.00 to $50.00; pastures from 4 to 25 cents per acre; residences covering from one to three acres cost from $5.00 to $25.00; resorts from $10.00 to $50.00; stores from $5.00 to $50.00 for two acres or less; and other uses in proportion. Perhaps the use that is purchased most of all on the National Forests is that for residences and summer homes. On many of the Forests they are already in great demand. A large proportion of the population of the far Western States seek the cool and invigorating air of the mountains in the early summer because the heat of the valleys, especially in California, is almost unbearable. There are many desirable pieces of land on the National Forests that are being reserved by the Forest Service especially for this purpose for the people of the neighboring towns. For example, on the Angeles National Forest in California the Supervisor had about 250 suitable sites surveyed in one picturesque canyon and in six months 226 of them were under special use permits as summer homes. A large reservoir--Huntington Lake--was constructed on the Sierra National Forest in California as the result of a dam constructed by a hydro-electric power company. Immediately there was a keen demand among the residents of San Joaquin Valley for summer homes on the shores of the lake. In a few years it is expected there will be a permanent summer colony of from 2,000 to 3,000 people. The Forest Service has already authorized an expenditure of $1,500 in order to furnish an adequate supply of domestic water for the colony. CLAIMS AND SETTLEMENT Claims can be initiated upon National Forest lands under (1) the Act of June 11, 1906, (2) under the mining laws, and (3) under the coal land laws. In connection with these claims it is the duty of the Forest Service to examine them, but the determination of questions involving title is within the jurisdiction of the Secretary of the Interior.
