THE SumMER Bup or “YEMA” GRAFT OF THE VINE. 
Following on the devastation by the phylloxera of the Victorian 
vineyards, reconstitution by means of resistant stock grafts has 
of late years been vigorously carried out. This work, entrusted to 
Mr. F. de Castella, the Government Viticulturist, has been crowned 
with signal success. After a voyage of investigation through the in-

fected regions of Southern Europe, Mr. de Castella introduced and 
adapted to Australian requirements many methods which have 
proved greatly beneficial in connection with the task entrusted to 
him. Amongst these the summer bud or “Yema” graft has simpli- 
fied field grafting, and has proved a distinct advantage to vine- 
growers.
