PYRAMIDAL PLUM TREES.

As these crab stock trees grow more freely than the 

 Paradise stock trees, summer pinching, or shortening 

 the young shoots with a penknife, as recommended in i 

 p. 08, must be attended to, and then, in the most un- 

 favorable apple tree soils, healthy and most prolific 

 pyramids may be formed. Any of the varieties re- 

 commended in pp. 67 and 68 will succeed well as 

 pyramids on the crab-stock. 



If managed in this manner, fine trees maybe formed, 

 not only of the robust-growing kinds, but even of the 

 old Nonpareil, Grolden Pippin, Golden Peinette, 

 Hawthornden, Pibston Pippin, and several others, all 

 more or less inclined to canker. I have a row of 

 Nonpareils and Ribston Pippins planted in the cold- 

 est and most unfavorable soil I could find, yet, owing 

 to their being biennially removed, they are entirely 

 free from canker. 



The vigorous growth of standard apples, when 

 planted in orchards in the usual way, is well known, 

 and also their tendency to canker after a few years of 

 luxuriant growth. Pyramids on the crab, without 

 occasional removal, or root- pruning, would, in like 

 manner, grow most freely, and, even if subjected to 

 summer pinching, would soon become a mass of en- 

 tangled, barren, cankered shoots. 



PYRAMIDAL PLUM TREES. 



The plum, if planted in a rich garden soil, rapidly 

 forms a pyramid of large growth — it, in fact, can 

 scarcely be managed by summer pinching. It be- 

 comes crowded with young shoots and leaves, and the 

 shortening of its strong horizontal branches at the end
