hot-lime, and soot in equal parts applied to the pipes, 

 also help to keep it in check : the former does no 

 harm to the vines, but it must not be applied till the 

 grapes have approached the stoning period, or the 

 result will be rusted berries. 



When vines get dry at the roots, they are very 

 subject to spider; and it is important for this cause, 

 if for no other, to ' keep them regu- 

 larly moist. The old loose bark 

 should be cleanly removed from vines 

 every year and be well scrubbed with 

 soap and water, using a rather stiff 

 brush. Every part of the wood- 

 work and glass should be thoroughly 

 scrubbed every year, and kept well 

 painted, the walls washed with hot- 

 lime, having a little sulphur mixed 

 with it, the pipes painted yearly, and every crevice in 

 which the foe can find a refuge filled up. 



Thrip (fig. 12). — This is an insect which can hardly 

 be said to be indigenous 

 to the vine ; but when 

 plants, such as azaleas and 

 others, are kept in vineries, 

 thrip is very apt to get on 

 the vines. It is very 

 troublesome and destruc- 

 tive. Of course the best 

 preventive is to keep plants 

 which are subject to it out 

 of vineries. Hand-spong- 

 ing and fumigating with 

 tobacco-smoke for two or three consecutive evenings 

 are the most effectual ways of dealing with it. Like
