THE CONTROL FORMS.

the yield and the actual fellings made against this yield. Thus if 

 sal and sain or asna (Terminalia tomentosa) down to 8" diameter 

 are included in the enumerations and the calculations of the 

 yield, both tnese species down to the same diameter class 

 will be included in the total of trees felled against the prescribed 

 yield, while other trees which may be included in the annual 

 markings will not count against the total but will be considered 

 as incidental revenue. 



Again in cases where the yield is regulated by area, the area 

 felled over is the important entry but in order to maintain a record 

 of the fellings and so that the controlling officer may see what 

 sort of fellings have been done, a list of trees felled is also 

 required. 



Similarly when sowing and planting is ^prescribed a suitable 

 control form is provided for the record of work done and ita cost. 



The actual outturn of any felling is not an essential for work- 

 ing plan control and is of no use for the preparation of yield or 

 volume tables. It is however of value at future revisions of the 

 plan and as a check on prices received for the coupe, and the 

 information should be included in the remarks column of the 

 control form or in the compartment history. Outturn depends on 

 many variable factors the chief of which is the location of the 

 coupe and facility of export, and it is never a constant of volume 

 marked for felling. 



The rules regarding the preparation of control forms and 

 examples of actual forms in use are given at the end of this chapter. 



The compartment history is a record of the history of every 

 compartment and has already been described in chapter V. Its 

 proper maintenance up to date is ordered in rule 8 of the control 

 form rules. 



This should contain matters of divisional importance as 

 opposed to information which only concerns the individual com- 

 partment. Such matters as the following would have their allotted 

 place and entries should be made from time to time as necessary.
