154 THE BOOK OF THE ROSE chap. 



Two or three turns of a thin bit of Eaffia are first 

 taken round the lower part of the sloping cut on the 

 stock leaving the ends underneath. A third hand 

 comes in very usefully here, and the operator 

 generally utilises his mouth for the purpose. The 

 end of the scion is thus held ready for putting into 

 position under the tie, which is then tightened and 

 finished by the hands. 



It is not necessary to make the circles of the tie 

 touch each other, nor are wax and clay used for 

 keeping out the air. The pot is immediately placed 

 in bottom heat in a frame which excludes the air, 

 and it is most interesting to watch the callus or 

 cambium growth forming between the two barks. 

 The bud will probably start in about three weeks, 

 and then air will be gradually given, and a high but 

 even temperature maintained till the plant has 

 grown sufticiently to be hardened by degrees and to 

 stand exposure to an ordinary mild atmosphere. 



The young growths will be very liable to " damp 

 off," and the usual precautions against this 

 catastrophe, of admitting air above, even in frosty 

 weather when the heat must be increased, must be 

 strictly attended to. Eoses raised in this manner 

 are not so good for planting out as budded ones, 

 but are useful for providing buds for outdoor propa- 

 gation, and nowadays good pot plants, especially of 

 the climbing varieties, are established in this way. 



Where there are no appliances of close frames 

 with bottom heat, the operation must be deferred to 

 a little later in the year, the stocks must be in a 

 more forward condition, and grafting wax must be 

 used to cover the whole of the operated parts 

 closely, as is the case with fruit-trees grafted in the
