The regular grazing permit carries with it the privilege of driving the permitted stock over National Forest lands to and from the allotted ranges at the beginning and end of the grazing season and from the range to the most accessible shearing, dipping, and shipping points during the term of the permit. But crossing permits are necessary for crossing stock over National Forest lands to points beyond the National Forest, for crossing stock to private lands within a National Forest, or for crossing stock to reach dipping vats or railroad shipping points. Rangers sometimes are detailed to accompany the stock and see that there is no delay or trespassing. No charge is made for crossing permits, but it is absolutely necessary that persons crossing stock comply with the regulations governing the National Forests and with the quarantine regulations prescribed by the Secretary of Agriculture and the state authorities. _Grazing Fees._ The full grazing fee is charged on all animals under 6 months of age which are not the natural increase of stock upon which the fees are paid. Animals under 6 months which are the natural increase of permitted stock are not charged for. A reasonable fee is charged for grazing all kinds of live stock on National Forests. The rates are based upon the yearlong rate for cattle, which is from 60 cents to $1.50 per head, depending upon conditions on the Forest. The yearlong rates for horses are 25 per cent. more and the yearlong rate for swine 25 per cent. less than the rate for cattle. The rate for sheep is 25 per cent. of the yearlong rate for cattle. The rates for all kinds of stock for periods shorter than yearlong are computed in proportion to the length of the season during which the stock use National Forest lands. All grazing fees are payable in advance. When notice of the grazing allowance, periods, and rates for the year has been received by the Supervisor he gives public notice of a date on or before which all applications for grazing must be presented to him. These public notices are posted in conspicuous places, usually in the post offices. Applications for grazing permits are submitted on blank forms furnished by the Supervisor. As soon as an applicant for a grazing permit is notified by the Supervisor that his application has been approved, he must remit the amount due for grazing fees to the District Fiscal Agent and upon receipt of notice by the Supervisor that payment has been made a permit is issued allowing the stock to enter the Forest and remain during the period specified. All grazing fees are payable in advance and the stock is not allowed to enter the National Forest unless payment has been made.
