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 joxmg 

 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 rnde blasts of the storm-king : in a less degi-ee, 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 noai- tlie base of the stem. The same thing 

 is not so often seen in tlie 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 upriglit 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 vai-ieties, begin to be appreciated, 

 and as the demand increases, our intelligent nurserymen 

 will very soon furnish the requisite supply. 



Plantin ff.-^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
