In the early days of the Forest Service prospective recruits were required to provide the best answers to a written exam and perform well in a field test to be selected for the job.  The written portion of the exam consisted of only ten questions but many of them were complex and included a set of intricate and sometimes complicated sub-questions. From the exam:

• Question 2. Describe in detail logging in a locality with which you are familiar, covering all operation, from felling the tree to delivery of logs at the sawmill, using all ordinary names applied to the men, operations, and implements.
• Question 4. What are the dimensions of a township? Section? Quarter section? A forty? A square acre? How many links in a surveyor’s chain? How many feet? How many chains in a mile? How many acres in a tract of land 600 feet wide by 3960 feet long?
