FALL PLANTED TREES SHOULD BE CUT 

 BACK. 



OF late some have advocated leaving 

 the branches uncut on newly planted 

 trees. This we count a mistake, both 

 from theory and experience. Evapora- 

 tion takes place from a tree most rapidly 

 from the leaves in summer, and it also con- 

 tinues, though in a much lesser degree, 

 from the wood of its branches all through 

 the winter. A tree that is growing renews 

 the supply from water in the soil, but a 

 newly planted tree is not yet able to do this 

 rapidly enough, unless the wood surface is 

 much lessened by pruning, and the colder 

 the air the more it draws upon the moisture 

 of the tree wood. 



Peach, plum and cherry trees are much 

 more inclined to lose moisture rapidly than 

 apple trees, and hence need much closer 

 pruning when set. 



For this reason it is usually found unsafe 

 to plant trees in the fall in Ontario ; the 

 cold of winter robs them of moisture and 

 consequently of their vitality so rapidly dur- 

 ing the time between setting and the spring 

 time, when the rootlets begin to act in sup- 

 plying moisture, that they are usually much 

 stunted for the first season, if not entirely 

 killed. For these reasons we are advocates 

 of spring planting of trees of all kinds in 

 Ontario, rather than autumn. There is 

 plenty of work in the autumn ploughing and 

 laying out the ground, and getting it in 

 readiness for setting the trees in spring, 

 when, if they come fresh from the nursery 

 ground, with no exposure to dry them, they 

 should continue growing as if they had 

 never been moved. 



A SPRAYINC^ OUTFIT. 



THE increasing necessity of thorough 

 spraying, year after year, renders it 

 most necessary that we prepare the best 

 apparatus for the work. We have evils

enough already to fight in codling moth, 

 apple scab, etc., but Mr. G. E. Fisher, San 

 Jose Scale Inspector, warned us at Walker- 

 ton that this worst of all evils was spreading 

 rapidly in districts where it has a footing, 

 and that almost every possible means helps 

 its spread, as birds and insects and even the 

 wind. Cold does not prevent its growth, nor 

 check its spread, for in Minneapolis it is 

 known to thrive with a temperature 40° be- 

 low zero. Fortunately we have in the lime 

 and sulphur treatment, a cheap, effective, 

 safe and easily applied remedy. 



Our worthy exchange, the American 

 Agriculturist, gives the accompanying illus- 

 tration of a well built spraying outfit with 

 the following remarks : 



For spraying large trees a platform above 

 the bed of the ordinary wagon is needed. 

 The tops of the trees can be reached with ex- 

 tension rods to which the hose is attached, 

 but such spraying is not satisfactory. Best 

 results are obtained where the spray is
