312 BULLETIN 226. 



It is difficult to tell just how much effect the better care will have in pro- 

 longing the life of the trees, but it is quite certain that the well-cared-for 

 orchards* will continue to pay much longer than the average. But over 

 half the orchards are not well cared for, and it is perfectly reasonable to 

 suppose that many of these neglected ones will be gone in twenty years. 

 The advisability of planting more orchards to take the place of these old 

 ones is therefore worth considering. More immediate profit would come 

 from the rejuvenation of the old orchard.
