GRAFTING OF THE VINE ABOVE GROUND.

observing certain precautions which are necessary, as we 

 ascertained last year in the experiments carried out at the 

 School of Agriculture, Ondes. Salgues' graft consists in fixing 

 on a green shoot of the year an elliptic scion or shield carry- 

 ing a bud at its centre (Figs. 17 and 18). On any internode 

 of the shoot to be grafted, a longitudinal incision is made 

 with the grafting-knife, penetrating the whole depth of the 

 bark and of about the length of the shield (Fig. 15) ; with the 

 haft of the grafting-knife the bark is raised on both sides 

 of the slit ; the shoot is then bent inwards and the lips of 

 the slit open easily (Fig. 16), the scion bud is inserted in 

 the opening, and the shoot left to spring up in its former 

 position. The scion bud is then compressed by the bark, and 

 the operation is completed by tying with wool, cotton, or 

 raffia. The 'ligature should be removed a fortnight or 

 twenty days after. This method, as may be readily seen, is 

 much simpler than the Horvath process.

For the Salgues graft to be a success it is necessary, 

 firstly, that the stock should be in full sap, so that the lips of
