vdneyard soil is saturated with moisture, as it was during tlie whole of 

 October last in most Rutherglen vineyards. In many of these, dray 

 traffic was impossible, let alone a spray outfit with wheel-driven pump. 

 Et must be remembered that it is precisely in a wet season that spray 

 protection is most vitally needed. In a dry spring, w^hen the ground is 

 usually fit for traffic, it is much less necessary. One vineyard owner, 

 realizing the unsuitability of his soil for the wheel-driven spray pump 

 in October, has already expressed his intention to adopt a motor-driven 

 pump placed on a sledge. 



"What is Eeally Required. 



Spraying is something quite new to most of our vine-growers. As 

 experience is gained in the work, modifications and improvements will 

 no doubt suggest themselves. In the meantime, much can be learnt

from our great Ally, France, to whom the world is already indebted 

 for the solution of the phylloxera problem. The foregoing is largely 

 based on information derived from French sources. It must be borne 

 in mind, however, that our vineyards differ a good deal from those of 

 Europe; local conditions, both climatic and cultural, must be taken 

 into consideration. It is hoped that the present article, which deals 

 with principles rather than matters of detail, may prove of service to 

 those now making provisions for spraying their vineyards next spring. 



Even in France, modifications in certain directions seem to be 

 desirable, as will be seen from the following extract from an article 

 on MildcAv bv Professor Ravaz.*
