in rows one meter apart. In May potatoes are planted between 

 these rows and about half of a full crop grown. They are sold in 

 the ground the purchaser removing the crop from a definite area. 

 The following year a little cultivation is given and the grass cut 

 out where necessary. Cropping more than a single season does 

 not yield enough to pay for the seed potatoes. Yet the crop does 

 not impoverish the soil nearly so much as the current practice of 

 raking up the litter for removal and use. The proceeds from the 

 potato crop reduces the cost of restocking the cut over areas by 

 one-third. Beech seedlings are set out in the fall or spring follow- 

 ing the potato harvest. The plants are best set in the same rows 

 with the pine because here they are less subject to browsing by 

 deer. Usually the plantations are fenced for protection against 

 rabbits and deer, the cost of such protection being paid by a part 

 of the income from hunting licenses. 



Pine seedlings from Halstenbek grown on heavily fertilized 

 soils gave much better results than those grown in the poor soil 

 near by. Excellent plant material was, however, produced in the 

 rich mountain valleys a little farther to the eastward. 



Rabbits, blight and the white-spotted weevil (Pissodes nofatus) 

 are the chief enemies in plantations. Carbon disulphide, grubbing, 

 trapping, ferreting and shooting are used to keep rabbits in check. 

 Spraying is used for the blight. The weevil is hardest to reach, 

 the only effective method of combatting it is to pull up and bum 

 trees infested with egg masses. These can be readily distinguished.
