GENERAL ESTIMATE^ 183 



In using this general estimate and apportionment it is neces- 

 sary to avoid too great rigidity, for it is to be expected that all 

 estimates will be modified to suit changed conditions. 



With this Estimate of Income and Expenses may \vell go a plan 

 of organization or personnel necessary in care of the property, and 

 here as in apportionment of funds, there should be a statement ex- 

 plaining what is really needed for best results, as well as a list of 

 men which may actually be employed under present conditions. 



From the foregoing it is evident that the General Plan is neces- 

 sary for any intelligent, business-like work on a large forest prop- 

 erty, and that this General Plan or Plans require considerable infor- 

 mation for satisfactory basis. From this it follows that different 

 parts of the Plan will differ in value, and that different parts will be 

 worked out and improved more or less independently, but also that 

 their interdependence is so great that a careful correlation is neces- 

 sary. It is clear, too, that in our new enterprises, where forest 

 administration starts with very little exact information regarding 

 the property, these plans are only tentative at first and require 

 revisions as fast as information is gathered. Experience in the 

 United States shows that, at first, these General Plans need modi- 

 fication every year, and take on the appearance of the Detail Plans 

 to be discussed, and that commonly the line between these two 

 practically disappears. This condition will not continue; as soon as 

 information is ample and reliable, and as fast as conditions of mar- 

 ket and transportation take on a more settled form, the General 

 Plans become more and more definite and permanent. 



DETAIL PLANS. 



The Detail Plans take up various lines of work on the forest as 

 outlined in the General Plans, and also various less important tasks, 

 coming up in administration of the property. These plans, usually 

 in tabular form, state exactly what is to be done during the coming 

 vear, or few years, enumerating the particular forties to cut, various 

 sales under way, men holding grazing, etc., permits, number of 

 stock of each, etc. These plans then tell the forester what to do 

 now, where to work, and in silviculture, etc., the method to follow.
