outside trees would screen the inner ones. 

 The trees should be set irregularly, and not 

 in rows, as the leading shoots do not receive 

 protection, the current of wind rushing along 

 between the rows. 



The oak plants should be at least seven 

 thousand per acre ; the thicker they are 

 planted the sooner they recover transplanting. 

 The four feet apart system requires two 

 thousand seven hundred and twenty-two trees 

 per acre ; the three feet, four thousand eight 

 hundred and forty trees, and the number 

 recommended will be two thousand one 

 hundred and sixty trees more than the 

 last number ; the shelter to be obtained 

 by the greater number of plants must b^ 

 obvious. 



It is not to be supposed that the whole 

 would be done in one season ; continuing the 

 planting of trees late in the spring must be 

 condemned, because many failures have been 

 witnessed from this cause.
