The Calling off in the revenue will be a'i the less appreciable, 

 the greater the number of years over which the periol of dimi- 

 nished receipt is spread, aa 1 actually this period is equal to the whole 

 length of the ne^ High Forest Rotation. In the majority of cases 

 we see in this one reasoa the more. i.ad that a pj^erfal one, fjr

 The art of the Amenagiste oners him no other means of mitigatkig

There is often reas<:'n to fear Tride fl::;ttiatiGris in the yield of 

 a forest under coaversioa during the various successive Pericis of 

 the Rotation. For instance, if after comparatively productive ex- 

 ploitations daring the First Period there enstied a sudlea falling off

The establishment of a ReseiTe Fand offers the first means to
