JAN.] PRUNING WALL-TREES. 199 



for their suppression. At that season, also, the mean 

 that might work their destruction, often works that 

 of the foliage and fruit, on account of its powerful 

 effects on the juices, which are then in an active 

 state, circulating through every part of the plant. 

 Winter is therefore the proper season to apply tlie 

 following solution, when the juices are determined 

 to the root, viz. 



Soft soap, two pounds ; flowers of sulphur, two 

 pounds ; leaf, or roll tobacco, two pounds ; nux 

 vomica, four ounces ; and turpentine, an English 

 gill J boiled in eight English gallons of soft or river 

 water, to six. It is to be used milk-warm. 



Unnail or untie all the branches from the wall or 

 trellis ; brush every part of the tree clean with a 

 soft brush, such as is used for painting ; then with a 

 sponge, carefully anoint every branch, shoot, and 

 bud; being sure to rub it well into every joint, hole, 

 and angle, as it is there the eggs or larvag of the in- 

 sects are chiefly lodged. The rails, spars, &c. of 

 the espalier or trellis, should also be anointed as 

 above. 



To insinuate, that a v^'all should also be thus a- 

 nointed or washed, may be thought going too far, 

 though there cannot be a doubt of its efficacy, in 

 that case, in eradicating all or most insects that in- 

 fest our fruits. At any rate, none will hesitate to 

 anoint a plastered wall, which may very easily be 

 done, on account of its smoothness ; and such walls 

 frequently occur, not only in hot-houses, but out of 

 doors, against which trees are trained.
