parts has been established, the plants are still left nnder 

 glass, but partially exposed to the air in the frame or honse 

 by removing the cloches. If the grafting has taken place 

 in autumn, the plants already grafted in frames are left there, 

 and those which have been grafted in the house are also put 

 under frames, where they will remain during the winter. 

 When spring comes, the lights are raised in the day-time ; in 

 the month of May the plants are removed into the open air, 

 and should be placed at the north side of a building or 

 evergreen hedge. If the grafting has been done in spring, 

 the plants which have been grafted under cloches or frames, 

 and which have been already partially exposed to the air, 

 should be put out in the same way in the shade. Plants 

 grafted in a house should be put for a month under a frame, 

 the lights of which should be raised in times of great heat ; 

 after this they are put out for a while in a shady place 

 before they are finally committed to the open ground. In 

 nurseries, this shading quarter is formed by a row of ever- 

 greens with compact and well-clipped foliage. The Chinese 

 Arbor vitas (Biota orientalis) is generally used for this purpose, 

 planted from east to west, so as to afford a full north aspect, 

 and at a distance of two feet from each other. For stocks as 

 tall as five or six feet, a row of trees planted at least six and 

 a half feet from each other will afford an excellent shade. The 

 higher the shading is required to be, the greater should be 

 the distance between the trees which form it, in order to 

 admit a free circulation of air. When the plants are placed in 

 the shade they should be moved into larger pots, and should be 

 plunged in groups in beds at the foot of the shading trees, 

 where they are to remain a year or two in the same pots. When 

 sufficiently grown they are again moved into larger pots. 

 According to their nature, they may be subsequently planted 

 permanently in shade, or in the open ground, or in the inter-
