tain the cut for any period, add together the estimates of the timber to 

 be expected on the stands which, according to the prescriptions of 

 management, will be cut during that period. 



The tendency toward a system of management by area, indicated 

 in the procedure described above, will be checked by the frequent re- 

 examination of the growing stock and the revision of the stand classifi- 

 cation to take into account the changes brought about by the different 

 site factors. 



Now as to the plan : The visible evidence of it is contained in a 

 brief report, with addenda in the shape of estimates and descriptions, 

 and a map of the working circle. 



THE, MAP 



The map is on a scale of 2 inches to the mile and shows graphically 

 the following data : 



1. Boundary of working circle. 



2. Existing. ways of transportation, such as roads, trails, flumes, 

 tramways, railways, telephone, telegraph, and power lines. 



3. Towns, settlements, forest utilization plans, farms, etc. 



4. Topography by contours if data exist ; if not, main features, such 

 as streams, main ridges, etc. 



5. Locations and extent of the different "stands." The age class 

 (by 20-year classes) of each "stand" on the area is shown and if it 

 belongs to a class slated to be cut within the next 20 years, the estimate 

 of the amount to be cut is entered. 



6. The cutting plan for the next five years : This is shown by des- 

 ignating the stands to be cut and the preferred order of cutting by 

 cross-hatching or by coloring and numbers. 



7. Areas needing planting. 



THE REPORT 



The report in brief consists of : 



1. General description of soil, climate, topography, etc., for the 

 whole circle. Explanation of map. 



2. Discussion of economic conditions in full, including recreational 

 values. 



3. Forecast of probable development of industries, local and distant, 

 future needs of population, growth of towns, development of means of 

 transportation, etc. 



4. Discussion of management survey, divisions into stands, esti- 

 ' mates, rate of growth and general silvicultural conditions and needs. 



Objects of management.
