The Supervisor spends about half his time in the office and half in the field, inspecting the work of his men and consulting with them, meeting local residents or associations of local residents who have propositions to submit for improving the service of the forest to them, or for correcting mistakes, or who wish to lay before the Supervisor some one of the numberless matters in which the forest affects their welfare. The usefulness of the Supervisor depends as much upon his good judgment, his ability to meet men and do business with them, and his knowledge of local needs and local affairs, as it does upon his knowledge of the forest itself. As in the case of every superior officer, his attitude toward his work, his energy, his good sense, and his good will are or should be reflected in the men under him, so that his position is one of the greatest importance in determining the success or failure of each National Forest, and hence of the Forest Service as a whole. More and more of the trained Foresters in the Service are seeking and securing appointments as Forest Supervisors because of the interest and satisfaction they find in the work. Such men handle both the professional and business sides of forest management. Many of their duties, therefore, are described in the succeeding chapter.
The position of Supervisor is in many respects the most desirable a trained Forester can occupy in the Forest Service, and the most responsible of the field positions.
To each forest where timber cutting has become important there are assigned one or more Forest Assistants or Forest Examiners. These are professionally trained Foresters. They are subordinate upon each forest to the Supervisor as manager, but it is their work which has most to do with deciding whether the Forest Service in general is to be successful or is to fail in the great task of preserving the forest by wise use.
The Forest Assistant secures his position with the Service by passing an examination devised to test his technical knowledge and his ability. After he has served two years as Forest Assistant the quality and quantity of his work will have determined his fitness to continue in the employ of the Government. If he is unfit he may be dropped, for there are many young and ambitious men ready to step into his place. If he makes good he is promoted to the grade of Forest Examiner and is put definitely in charge of certain lines of professional work; always, of course, under the direction of the Supervisor, of whom he becomes the adviser on all problems involving technical forestry.
