in timber sales, recreation-area use, or research activities 

 that require the use of practical skills and experience; 

 collecting, consolidating, sometimes analyzing, reporting, 

 and summarizing data within guides set up by professionals ; 

 contacting the public, contractors, and other forest users for 

 information or policy enforcement; or supervising a road 

 survey crew on a road-building project that will make 

 timber accessible for harvesting. 



B. AID. — No organization can exist without people who know 



how to get the basic or preliminary work done. The Forest 

 Service is no exception. It has always been fortunate in 

 having hard-working aids who not only get the job done, 

 but enjoy doing it. 



Aids, even more than technicians, work at a variety of 

 productive tasks that help both the technician and the pro- 

 fessional. Some of these tasks are: Scaling logs; marking 

 specific trees and collecting and recording such data as tree 

 heights, tree diameters, and tree mortality ; installing, main- 

 taining, and collecting records from rain gauges, streamflow 

 recorders, and soil moisture measuring instruments on 

 simple watershed improvement projects; serving on a road 

 survey crew as rodman, rear or head chainman, notekeeper, 

 or level instrument man. 



C. CLERICAL PERSONNEL.— Another important group of 



support personnel in the Forest Service is the clerical and 

 related staff. Clerical workers are found at all organization 

 levels, including the forest ranger's office. A unit may require 

 the services of one or more of the following: Clerk typist, 

 voucher examiner, stenographer, mail and file clerk, and 

 dictating machine transcriber. 



D. SKILLED WORKER. — For construction, maintenance, and 



fire control projects, the Forest Service requires such skilled 

 workers as carpenters, parachute repairers and packers, 

 welders, cooks, bulldozer operators, and others experienced 

 in specific trades and crafts. In addition, maintenance workers 

 are employed to perform a variety of tasks requiring skills 

 of less than journeyman level. 



E. LABORER. — In addition to skilled workers on the numerous 



National Forest projects, laborers are also needed. Unskilled 

 workers destroy undesirable trees, using poison or other 

 methods; prune trees to improve their quality; build fire- 

 lines; eradicate bushes that transmit the destructive white 

 pine disease known as blister rust; plant seedlings; dig 

 ditches; load and unload equipment and tools; and perform 

 other supervised duties.
