 wines of excellent quality. 



Figs. 6, 7, and 8 illustrate vines similarly treated at tlie Rutherglen 

 Viticultural Station in October, 191S. Three consecutive frosts 

 occurred in the beginning of that month; the first two damaged the vines 

 slightly, while the third was much more severe. On many varieties 

 the whole of the crop then visible was entirely destroyed. Radical 

 disbudding was practised Avith excellent results, a good supply of 

 healthy wood for the following pruning being obtained. In the case of 

 many varieties the supplementary crop was quite remarkable, as will 

 be seen by the photographs here reproduced. Mondeuse maintained the 

 good reputation it has in France, which makes it the most popular 

 variety in valleys exposed to spring frosts in the Savoy district of 

 France. Even Aramon, although it was one of the sorts which was

 yielding more than half a normal crop : — Groslot, Mondeuse, Corbeau, 

 Aramon Bouschet, Terret Bouschet,' Semillon, Cinsaut, Chenin Blanc, 

 and Portugais Bleu.

It was rather poor with Gamay, Melon, . Aligote, Joannenc, Terret 

 Bourret, Aspiran Bouschet, Albillo, Joannenc, Carignane, Montils,
