The cost per acre, then, of growing and setting out stock of different 

 ages, differently spaced, would be as follows: 



Kind of stock. 



1-year seedlings 



2-year seedlings 



3-year stock (2 years transplanted) 



Spacing. 



6 by 6 

 feet. 



6.70 

 10.26 



8 by 8 

 feet. 



83.13 

 4.31 

 7.08 



10 by 10 

 feet.

It will be seen from the foregoing that where wide spacing is 

 practiced and nursery stock is grown on a large scale locally, planting 

 can sometimes be done as cheaply as direct sowing. Moreover, it is 

 always much the surer method. The cost figures given are, of course, 

 only applicable to operations properly planned and skillfully carried 



out. 



ALTERNATION OF FOREST AND FARM CROPS. 



There are large areas of rather poor sandy land throughout the 

 region in which loblolly pine occurs which will produce good farm 

 crops for a number of years after cleared of forest and brush, but the 

 fertility of which it is expensive to maintain for any considerable 

 length of time. Such land can sometimes be most profitably worked 

 on a system of alternating a forest crop of loblolly pine, grown on a 

 40 to 50 year rotation, with the use of the land for farm crops for a 

 period of from 10 to 15 years. The fertilizing effect on the soil in the 

 growing of a timber crop is in this way taken advantage of for agri- 

 cultural crops. In addition to this a new crop of loblolly pine can 

 be established very easily on the area when worn out by farming. 

 If there are sufficient loblolly-pine seed trees in the vicinity, the 

 reproduction will spring up naturally on the abandoned field, and 

 if not, the pine can be planted or sowed. This is a good method of 

 establishing a loblolly-pine forest on land which before cultivation 

 had no loblolly on it, and also one especially adapted for use by 

 resident farmers with woodlands adjacent to their farms. 



NURSERY WORK.i 



Where extensive planting operations are to be carried on it is best 

 to establish a forest nursery. The following are the essential points 

 to be held in mind in this work : 



Selection of Nursery Site. 



A site should be selected if possible with a light, moderately fertile, 

 well-drained, but uniformly fresh to moist soil, and located in the 

 open where there will be the least danger from disturbance by birds,

 and Yearbook Keprint 376, of the Dept. of Agriculture.
