The fourth branch, that of Grazing, supervises the use of the National Forests for pasture. Over the greater part of the West, this was the first use to which the forests were put, and an idea of its magnitude may be gathered from the fact that every year the National Forests supply feed for about a million and a half cattle and horses, and more than fourteen million sheep. It is no easy task to permit all this live stock to utilize the forage which the National Forests produce, and yet do little or no harm to the young growth on which the future of the forest depends. To exclude the grazing animals altogether is impossible and undesirable, for to do so would ruin the leading industry in many portions of the West. Consequently, many of the most difficult and perplexing questions in the practical administration of the National Forests have occurred in the work of the Branch of Grazing, and have there been solved, and many of the most bitter attacks upon it have there been met.

The fifth branch, that of Lands, has to do with the questions which arise from the use of the land in the National Forests for farming or ranching, mining, and a very wide variety of other purposes, and with the exceedingly numerous and intricate questions which arise because there are about 21,100,000 acres of land within the boundaries of the National Forests whose title has already passed from the Government. The boundaries of the National Forests also are constantly being examined to determine whether they include all the land, and only the land, to be contained within them, and whether they should be extended or reduced.

The first permits for the use of waterpower sites on Government land were issued by the Forest Service, and the policy which is just being adopted by the Interior Department and other Government organizations in their handling of waterpower questions was there first developed. These permits are prepared in the Branch of Lands. The first steps toward deterring men who attempt in defiance of the law to get possession of lands claimed to be agricultural or mineral within the National Forests are taken here, but the final decision on these points rests with the Department of the Interior. The examination of lands to determine whether they are agricultural in character, and therefore should be opened to settlement, is directed from this Branch.

The uses to which National Forest lands are put are almost unbelievably various. Barns, borrow pits, botanical gardens, cemeteries and churches, dairies and dipping vats, fox ranches and fish hatcheries, hotels, pastures, pipe lines, power sites, residences, sanitaria and school-houses, stores and tunnels, these and many others make up, with grazing and timber sales, the uses of the National Forests, for which already more than half a million permits have been issued. This work also falls to the Branch of Lands.

The sixth branch, that of Forest Products, is concerned with the whole question of the uses of wood and other materials produced by the forest. Its principal work is conducted through the Forest Products Laboratory, in coöperation with the University of Wisconsin at Madison. Here timber is tested to ascertain its strength, the products of wood distillation are investigated, wood pulp and paper studies of large reach are carried on, the methods of wood preservation and the results of applying them are in constant course of being examined, and the diseases of trees and of wood are studied in coöperation with the Bureau of Plant Industry of the United States Department of Agriculture. The consumption of wood, and the production of lumber and forest products, are also the subject of continuous investigation, and various necessary special studies are undertaken from time to time. At the moment, an effort is under way to find new uses and new markets for wood killed by the chestnut blight in the northeastern United States.

The seventh branch has to do with the study, selection, and acquisition of lands under the Weeks law, in accordance with which eight million dollars was appropriated for the purchase of forest lands valuable for stream protection, with particular reference to the Southern Appalachians and the White Mountains of New England. The examination of the amount of merchantable timber on lands under consideration for purchase, the study of the character of the land and the forest, and the survey of the land keep a numerous body of young men very fully occupied. Their task is to see that none but the right land is recommended for acquisition by the Government, that the nature and value of the lands selected shall be most thoroughly known, and that the constant effort to make the Government pay unreasonable prices or purchase under unfavorable conditions shall as constantly be defeated. The same branch takes charge of the lands as soon as they have been acquired.

The foregoing description of the work which is done in Washington by the Forest Service may help to make clear the great variety of tasks to which a Forester may be required to set his hand, and emphasizes the need of a broad training not strictly confined to purely technical lines. It would be defective as a description, however, and would fail to show the spirit in which the work is done, if no mention were made of the Service Meeting, at which the responsible heads of each branch and of the work of the Forester's office meet once a week to discuss every problem which confronts the Service and every phase of its work. This meeting is the centre where all parts of the work of the Service come together and arrange their mutual coöperation, and it is also the spring from which the essential democracy of the organization takes its rise. The Service Meeting is the best thing in the Forest Service, and that is saying a great deal.

It must not be imagined that the maintenance of Forest Service headquarters in Washington indicates that the actual business of handling the National Forests is carried on at long range. In order to avoid any such possibility the six District offices were organized in 1908. These are situated at Missoula, Denver, Albuquerque, Portland, Ogden, and San Francisco. Each of the District offices is in charge of a District Forester, who directs the practical carrying out of the policies finally determined upon in Washington, after consultation with the men in the field. The execution of all the work, the larger features of which the Washington office decides and directs (and the details of which it inspects), is the task of the District Forester. The District Forester's office is necessarily organized much on the same general lines as the Washington headquarters. Thus, the subjects of accounts, operation, silviculture, grazing, lands, and forest products are all represented in the District offices. In addition, a legal officer is necessarily attached to each District office, and each District Forester has in his District one or more forest experiment stations, employed mainly in studying questions of growth and reproduction; and three forest insect field stations, maintained in coöperation with the Bureau of Entomology, are divided among the six Districts.
