148 MODERN FOREST ECONOMY. 



It is more easy to make intelligible the treatment so 

 designated than it is to render in English the designation 

 given to it. The following may be taken as supplying a 

 rough and rude illustration of it in. its application to a 

 coppice wood. If the* coppice be one which may 

 profitably be cut down every twenty years, by dividing 

 it into twenty equal or equivalent portions, and 

 cutting one, but only one of these each year, there may be 

 obtained a constant supply of wood, the division cut in the 

 first year being ready again for the axe in the twenty-first 

 year of the operation, and again in the forty-first year, 

 while the other divisions follow in their order. 



This mode of exploitation has been extensively adopted 

 in the management of coppice woods in Russia, though 

 Jardinage is generally followed in the felling of timber. 

 I have found that there on many estates held by private 

 proprietors, there is carried out recklessly, and without 

 system, a succession of clearings in successive years one 

 portion cleared this year, another portion next year, a 

 third portion in the year following. On other estates, in 

 connection with mining and smelting operations, a some- 

 what similar exploitation is carried out more systematic- 

 ally. 



A similar mode of procedure has been adopted in several 

 of the Crown Forests. By Professor Sokanoff, who at the 

 time held the Chair of Forest Economy in the Forest 

 Corps at Lanskoi, near St. Petersburg, I was told when 

 there in 1873, that it was not uncommon, and it might be 

 considered the general usage, to fell the forest in long 

 strips of 50 fathoms, or 350 feet, in breadth, alternating 

 with strips of the same width on which the trees were 

 left standing to sow the cleared ground. Where wood is 

 scarce they clear these strips completely ; where it is 

 abundant they leave young trees unfelled to grow, or to be 

 destroyed in the removal of the others, as may happen ; 

 and when a new growth of trees has been fairly established 

 on the cleared strip, the strip of standing trees is cleared
