In selecting the stands for felling, the necessity of utilizing over- 

 ripe and deteriorating stands, sequence of a proper felling series 

 and finally maturity decide. 



The final budget in amount is found by dividing total area 

 into total yield, when the average felling yield per acre is estab- 

 lished, which is then multiplied by the periodic felling area. In 

 addition thinning results are estimated, but no need of equaliza- 

 tion of annual budgets exists. 



The rest of the article is concerned with the routine of the work 

 of regulation and of control.

The need of book-keeping on the farm as 



Value of far as field crops are concerned has been 



Woodlot long acknowledged as proper. An anony- 



Book- mous article tries to make propaganda for 



keeping. control of private forests, or woodlots. The 



incentive is given by the account of a Swiss 



forest owner who for 14 years has kept a budget control of his 



125 acres of woodlot, 3300 feet above sea level, managed for the 



last 20 years in a rational selection forest form. 



It is composed of .7 spruce, .2 fir and .1 beech. The area was 

 divided into compartments and the stock ascertained by counting 

 and figuring cubic contents of all diameter classes of 9 inch and 

 over. The cut was made from compartment to compartment and 

 measured. After 10 years the stock was again ascertained. The 

 result is interesting. Stock at beginning of period 2860 cubic feet 

 per acre; at end of period 3290 cubic feet. There had been cut 

 per acre and year 90.5 cubic feet; the increase in stock was 40 

 cubic feet; hence the total increment 130.5 cubic feet, or nearly 5 

 per cent, on the original stock. 



The owner, therefore, found out that he could increase the cut 

 without decrease of capital. 



The ease with which this control, by no means perfect, but 

 sufficient for the purpose, can be handled even by the inexperi- 

 enced man recommends it. The owner begins to realize the value 

 of his property and will manage it with more care.
