U. S. DEPARTMENT OF AGRICULTURE BULLETIN NO. 484. 



species suitable to the site and by cleanings until these are estab- 

 lished, probably for at least five years. (See p. 29.) Owing to 

 the great number of very small trees, between 1 inch and 2.5 inches 

 in diameter breast high, the cost per cord will be high and the 

 product poor cordwood, about 7 or 8 cords per acre. 



For planting on such sites, red or white pine or a mixture of both 

 is recommended, with white ash in the moister situations. Tulip 

 tree should also do well on sites suitable for Avhite ash, but if used 

 it should be considered as an experiment. Under the conditions 

 obtaining on this lot, planting an average of GOO trees per acre should 

 be sufficient, and the cost will be $8 to $10 per acre. 



The possibility of control without removing all Class I trees is 

 the object of experiments now being conducted on this and other lots. 

 Pending their conclusion, the above suggestions are made to guide 

 owners who wish to do something at once. Neither clear cutting nor 

 successive cuttings can be recommended in stands of this age and 

 character, and a gipsy-moth cutting can be recommended only for 

 owners who put gipsy-moth control above all other considerations. 



The result of the three plans is compared in the table following.
