PROPAGATION. 93 



been brought forward against this plan of multiplying the 

 apple. In our very changeable climate, and particularly 

 in the North-west, upon the prairies, the cold of winter 

 often supervenes with great suddenness, after the young 

 trees have made a prolonged and vigorous growth in the 

 fertile soil, and produces terrible devastation among those 

 that are there exposed, without protection of any kind, to 

 the rude blasts of the storm-king: in a less degree, injury 

 is very frequent with many such late-growing kinds, at the 

 first access of a severe frost ; this is manifested in the burst- 

 ing of the bark near the base of the stem. The same thing 

 is not so often seen in the same varieties, when they have 

 been budded or stock grafted a foot or more from the 

 ground upon hardy seedling stocks, hence judicious prop- 

 agators have selected the " tender " varieties for this kind 

 of working, and confine their root-grafting to those less 

 liable to the injury. There are other varieties which do 

 not readily and promptly form a strong upright growth, 

 so as to be profitable trees to the nurseryman if root 

 grafted; these are selected for stock working, either on 

 strong seedlings, or upon hardy upright sorts that have 

 been root grafted for the purpose of being thus double- 

 worked. This plan has been pursued to a limited extent 

 only, but its advantages in the production of good trees 

 of the slender growing varieties, begin to be appreciated, 

 and as the demand increases, our intelligent nurserymen 

 will very soon furnish the requisite supply. 



Planting. When the weather is fine, and the soil in 

 good condition, the root-grafts are to be set out with a 

 dibble, by the line ; they should be planted rather deeply, 

 one bud projecting above the surface of the ground. The
