speaking of adaptation to soil (page 55) ; and it was shown 

 that it is possible to obtain good graft-bearers resisting 

 chlorosis in calcareous soils. But it is possible, however, 

 to efficiently combat this malady on vines established under 

 bad conditions, from the point of view of their adaptation, 

 by using Dr. Rassiguier's process. 



This process consists in painting the sections after pruning 

 with a solution of sulphate of iron, of 30 per cent, strength. 

 The sooner the pruning is done the greater efficiency the 

 remedy seems to have, therefore it should be applied as soon 

 as the vine begins to shed its leaves. If spring frosts are 

 feared the pruning may be done twice, leaving the spurs 

 1 foot or 18 inches long, and painting the sections directly 

 after the first pruning. The action of the liquid is the 

 same in this case as if it had been applied at the definitive 

 pruning. 



The results obtained by this process are excellent, and 

 enable us to recommend it.
