crossing of which the seedless grape was derived. It would be interesting 

 to settle, first of all, if the Corinth is the result of a cross; and, second 1}, 

 if we have here the original parents from which it was derived. That is 

 one point, at least, which can be determined (although it will take some 

 time), from the seeming erratic behaviour of the bud of the Corinth, as 

 both seeds will be i)lanted, and the cross can afterwards be made. My 

 colleague, Mr. Castella, has kindly supplemented this brief account of a 

 remarkable occurrence, and his large experience and extensive knowledge 

 peculiarlv fit him for throwing some light on this perplexing subject.

I have examined, with much interest, the curious bunches of grapes 

 borne, at Mildura, by a Corinth currant vine, which were brought under 

 my notice by our Vegetable Pathologist, Mr. D. McAlpine, who has al- 

 ready described the occurrence in detail, and obtained photographs of the 

 two specimens. I'his is one of the strangest freaks of the kind which has 

 come under my notice ; it is one which may lead to most interesting results, 

 and, when followed up, may throw light on several questions of wider 

 than merelv viticultural interest.

SELF AND ARTIFICIALLY FECUNDATED BUNCHES. 



The large question of bud-variation and sporting is concerned, and 

 information may be obtainable which will enlighten us as to the origin 

 of the Corinth vine, which received so little attention in viticultural 

 literature. 



Sports are not uncommon in the case of the vine. The Centennial 

 grape is an example. This is a sport from the Waltham Cross variety, 

 which has been fixed and perpetuated by cutting propagation. Sports are 

 responsible for frequent changes in colour, shape, and size of fruit.
