METHODS OF GRAFTING 71 



worked in heat may be grafted either saddle or wedge 

 fashion, but saddle grafting is the best and makes the 

 strongest union. The graft should be not quite so large 

 as the stock, so as to leave enough room to make a good 

 callus. The wedge grafting is for using small bits of choice 

 sorts. We use shallow boxes i foot wide, 2 to 3 feet long, 

 and 4 inches deep, packing the plants into them as closely 

 as possible (for when done in this way they are convenient 

 for moving from place to place), and then placing them in a 

 gentle, moist heat, under double glass if possible, though I 

 have seen very good results when they have been placed in 

 shallow pits, where these are heated with a couple of 3-inch 

 pipes along the front. In that case they should be sprinkled 

 or syringed twice a day, and shaded from the sun until they 

 start into growth, when air must be admitted very gradually 

 until they are hardened and fit to stand out in a shady 

 place until October, when they can be planted out. The 

 tender leaves made under glass will not stand summer sun. 

 In April I have seen very good results in a cold pit, and for 

 an amateur where only a few are required they will do very 

 well under a bell glass ; but they must be always attended 

 to as above. 



" Another method is to graft in August. This must be 

 side grafting, and the plants so done must be kept under 

 glass all the winter in pots, and should not be headed back 

 until the stocks have begun to grow, when the young 

 growth should be stopped back until the graft begins to 

 shoot ; the stock can then be headed back. Plants done in 

 this way may, after they have made their first growth, be 

 potted in larger pots and placed in a shady place, and they 

 will make fine plants by the autumn/'
