lOG GOOSEBERRY. 



mended, dusted on the leaves ■when the dew is on, or if in dry 

 weather after Avatering. 



Mr. W. J. Goodwin, of Winfield House, Crouch, Sevenoaks, 

 reported that he considered "the hest remedy for Gooseberry 

 caterpillars is to give a liberal sprinkling of fresh, good soot 

 early in the morning when the trees are damp, two or three 

 large haiidfuls to a good-sized tree, so as to make it quite 

 black witli soot. It is of no use unless it is done when the 

 trees are danip, so that it sticks on ivell. If it comes off by 

 rain coming shortly after, it must be done again. It acts, of 

 course, as a first-rate manure afterwards, causing the trees to 

 make good wood for another year." 



Another recipe for a good broadscale remedy found to work 

 well was sent me from White Hall Farm, Chewstoke, near 

 Bristol, as follows : — " It may be of interest to you to know 

 how I have exterminated the ' Gooseberry Sawfly ' and * Ked 

 Spider ' from my garden. For several years my Gooseberries 

 were completely spoiled by these pests. I made a couple of 

 hogsheads of strong lime-water, and thoroughly spra^yed the 

 bushes with it early in the morning * I had an assistant to 

 pull the bushes over, so that the liquid might reach the under 

 part of the leaves as well as the outside. After about five 

 minutes of this, I had the bushes violently shaken, when 

 nearly every insect dropped off; to complete their discom- 

 fiture, directly I had done shaking the bush I had the surface 

 of the ground freely dusted with air-slaked lime. I had this 

 done three times, at intervals of two days, and now I have 

 not the slightest trace of either in my garden. I find this 

 treatment is far better in the early morning than when it is 

 used at mid-day." — (E. W.) 



London-purple as an insecticide. — The following detailed 

 notes of method of (and also success of) ai^plication of 

 London-purple for getting rid of the sawfly caterpillars are 

 well worth attention, not only as a cheap and simple method 

 of getting rid of this s[)ecial pest, but also because, if properly 

 used, it is as serviceable for use as an insecticide as the better 

 known Paris-green. Bot]t, of the chemicals are jjoisonoits. The 

 Pariii-f/rcen is an aceto-arsenite of copper, the London-purple is 

 an arsenite of lime ; both therefore require care in use, as has 

 been specified before. 



The great difficulty in the first use of London-purple was 

 that in the U.S.A. (from whence, as well as in the case of 

 Paris-green, we first learnt its value) it was thrown out as a 

 waste product of such various strength that nothing but 

 special trial of extent to which it might need diluting made 

 its use safe. Here, however, we can procure analysis which
