206 THE ROTATION. 



upon certain rates obtainable for the various classes of pro- 

 duce, whereas a change in the actual rotation may alter 

 those rates. If, for instance, the calculated financial rotation 

 is lower than that actually existing, and the former is intro- 

 duced, more small and less large timber will be produced; 

 also the proportion between timber and firewood will be 

 altered. This may produce a fall in the average price of 

 produce, and consequently a rise in the financial rotation. 

 The reverse effect would be produced, if the calculated 

 financial rotation were higher than the one actually existing. 

 In either case it must be taken into consideration that a 

 change in the rotation is accompanied by a change in the 

 growing stock, and that either more or less material is brought 

 into the market, which may be accompanied by a change in 

 prices. 



It follows, that the first calculation is generally subject to 

 some correction in accordance with the alteration of prices 

 which may be produced by a change in the rotation. 



d. Introduction of the Financial Rotation. 



Although every deviation from the financial rotation is 

 accompanied by a financial loss, yet it is very desirable that 

 it should be introduced, if not already followed, with great 

 caution, because, in the first place, it can only be determined 

 approximately, and secondly, its introduction is accompanied 

 by a change in the existing growing stock. If a true, or 

 assumed, surplus of growing stock has been disposed of, it 

 would take much time to re-establish it, should further experi- 

 ence indicate a higher rotation than that originally calculated. 

 Hence, it is desirable to keep always somewhat above the 

 theoretical financial rotation. 



If a change of rotation has been decided on, it can be 

 carried out at once, provided the forest is of small extent, and 

 the demand for produce sufficiently large to absorb the extra 

 supply of produce thrown upon the market, without causing 

 any appreciable change in prices. If the forest is, however,
