Cultivation of the apple in Canada with descriptions and lists of varieties. cultivationofapp55davi Year: 1925 ( 11 protection in winter than deciduous trees. For shelter purposes it is planted eight to ten feet apart. In severe localities more than one row may be planted, in which case the rows may alternate, one tree in one row coming between two trees of the other. Where' it is necessary to obtain some sort of shelter more quickly than the white spruce growth will provide, the Caragana arborescens or Siberian pea tree may be used. This can be planted in front of the spruce, about ten feet or so from it, and being a rapid grower will afford protection in a very few years. This variety may be planted at from three to four feet apart and permitted to form a hedge. Other rapid-growing trees recommended for this purpose are Lombardy poplar, cottonwood, white pine, and European larch. Manitoba maple or box elder has been largely used on the prairie, but is not a long-lived tree, is very subject to insects, and although a quite hardy, rapid grower, is not to be as highly recommended as caragana or cotton- wood.

Protection from the north and west is usually desired, and in the greater part of Canada, is all that is required. On the prairies it often becomes neces- sary to entirely surround the plantation by a windbreak, and if the enclosure is of any great size, cross hedges of Caragana or some other tree are run east and west, thus establishing exceedingly well protected ranges about two hun- dred feet in width. Such an arrangement ensures the retention of snow and the maximum protection from high winds both in winter and summer.
