HOW TO PROCURE TREES. 33 



cultural College has used a mixture in the follow- 

 ing proportions for the past two or three years, 

 1,000 pounds pure bone meal, 300 pounds high 

 grade muriate of potash. This amount he con- 

 siders sufficient for an acre of land. The result 

 of this application, he thinks, has been entirely 

 satisfactory upon all kinds of fruits. But if the 

 growth of wood should seem at any time to be 

 inadequate to the tendency to fruit, an addition 

 of ammonia in the form of guano or stable manure 

 might be added. As the special fertilizers can 

 be easily spread, this may be done after the 

 trees are planted. And this supply should be 

 continued from year to year, varying the amount 

 of these three elements, potash, phosphoric acid, 

 and nitrogen, according to the condition of the 

 orchard. 



CUTTING BACK. 



However much care may be used in digging, 

 the roots are much reduced in transplanting 

 trees. Nor, as has been stated, is it to be re- 

 gretted that the small fibres at the extremities 

 should be shortened. But it is important that a 

 corresponding shortening of the limbs should 

 preserve a balance in the tree. The mode of 

 pruning is indicated in subsequent pages, under 

 the head of the different fruits. In general,
