Later, while the logging is under way, the Forest Examiner will often inspect it to see that the terms of the sale are complied with, that the trees cut are thrown in places where they will not unduly damage either young growth or the larger trees which are to remain, and that the other conditions laid down for the logging in the contract of sale are observed. The scaling of the logs to determine the amount of payment to the Government will many times be under his supervision, although in the larger sales this work, as well as the routine inspection of the logging, is usually carried out by a special body of expert lumbermen, who often bring to it a much wider knowledge of the woods than the men in actual charge of the lumbering.

In nearly every National Forest there are areas upon which the trees have been destroyed by fire. Many of these are so large or so remote from seed-bearing trees that natural reproduction will not suffice to replace the forest. In such localities planting is needed, and for that purpose the Forest Examiner must establish and conduct a forest nursery. The decision on the kind of trees to plant and on the methods of raising and planting them, the collection of the seed, the care and transplanting of the young trees until they are set out on the site of the future forest, forms a task of absorbing interest. Such work often requires a high degree of technical skill. It is likely to occupy a larger and larger share of the time and attention of the trained men of the Forest Service.

A FOREST EXAMINER RUNNING A COMPASS LINE

The Forest Assistant's or Examiner's knowledge of surveying makes it natural for him to take an important part in the laying out of new roads and trails in the forest, or in correcting the lines of old ones, and there is little work more immediately useful. The forest can be safeguarded effectively just in proportion to the ease with which all parts of it can be reached. Forest protection may be less technically interesting than other parts of the Forester's work, but nothing that he does is more important or pays larger dividends in future results.

In addition to his studies of the habits and reproduction of the different trees for working plans or timber sales, or simply to increase his knowledge of the forest, the Forest Examiner is often called upon to lay out sample plots for ascertaining the exact relation of each species to light, heat, and moisture, or for studying its rate of growth. He may find it necessary to determine the effect of the grazing of cattle or sheep on young growth of various species and of various ages, or to ascertain their relative resistance to fire. In general, what time he can spare from more pressing duties is very fully occupied with adding to his silvical knowledge by observation, with studies of injurious insects or fungi, of the reasons for the increase or decrease of valuable or worthless species of trees in the forest, the innumerable secondary effects of forest fires, the causes of the local distribution of trees, or with some other of the thousand questions which give a never-failing interest to work in the woods.

The protection of a valuable kind of tree often depends upon the ability to find a use for, and therefore to remove, a less-valuable species which is crowding it out, for as yet the American Forester can do very little cutting or thinning that does not pay. Just so, the protection of a given tract against fire may depend upon the ability to use, and therefore to remove, a part or the whole of the dead and down timber which now makes it a fire trap. For such reasons as these, the uses of wood and the markets for its disposal form exceedingly important branches of study for the Forest Examiner, who will usually find that his duties require him to be thoroughly familiar with them.

It is more and more common to find each Forest Officer—Ranger, Forest Examiner, or Supervisor—combining in himself the qualities and the knowledge required to fill any or all of the other positions. The professionally trained man who develops marked executive ability is likely to become a Supervisor, just as a Ranger, with the necessary training and experience, who may wish to devote himself to silvical investigations may be transferred to that work. The point is that each man has individual opportunity to establish and occupy the place for which he is best fitted.

The success of the technical Forester, like that of the Ranger, and indeed of nearly every Government Forest Officer, in whatever position or line of work, will very frequently depend on his good judgment and practical sense, the chief ingredient of which will always be his knowledge of local needs and conditions, and his sympathetic understanding of the local point of view. This does not mean that the local point of view is always to control. On the contrary, the Forest Officer must often decide against it in the interest of the welfare of the larger public. But the desires and demands of the users of the forest should always be given the fullest hearing and the most careful consideration. To this rule there is no exception whatsoever.
