English elin. Whale oil soapsuds, applied through a green-house 

 syringe, kills them all; as it does the lady-bug, so destructive to ro- 

 ses, cherries and grapes. I told my gardener to bring to you some 

 of the black elm caterpillars, but they died, and he did not think 

 them then worth carrying. 



A communication on a preventive of worm in peach-trees was 

 read. It says: 



I have, within the last six or seven years used the corrosive su- 

 blimate in two or three different ways, applied to my peach-tree 

 roots in the latter part of October, and have never found a grub on 

 any one of my trees in the spring, or any part of the year thereaf- 

 ter. The remedy must be well applied, and early enough to prevent 

 the little worms making their entrance at all, for, if they wound the 

 bark, however slightly, the tree will be injured, but they will be 

 killed by my remedy without delay, even when they are entirely 

 imbedded in the bark. 



The earth must be first removed from the trees, down to the de- 

 parture of tlie roots, and the surface well rubbed with a cloth or 

 brush, and all crevices and defects in the bark freed from the soil. 

 The preparation which follows, must then be applied, a little warm- 

 ed or softened, but not so much as to permit the powder to separate 

 from the mass. Then take an old, stiff paint brush, and thoroughly 

 cover every part and crevice of the bark with the preparation, from 

 the branching of the roots to about two inches above the ground. 

 Then surround this surface with a single bandage, made of old India 

 rubber cloth, oil cloth, or any cheap muslin well paintea and dried 

 for use, or any other covering which will certainly prevent the ab- 

 sorption of the corrosive sublimate by the wet earth. Then tie a 

 string round the bandage firmly at the upper end, above the ground, 

 and replace the earth, and pack it around the tree as before. In the 

 early part of the next April, take off the bandages, cleanse and 

 save them for use again. 



You will find the preparation still on the bark, but no grubs alive; 

 and if any are found in newly dressed trees, there will be nothing 

 more than the skins of. worms which had gained an entrance before 

 the dressing was applied. No grub can live under this dressing, if 

 applied as is here directed. I have made my preparation without 

 any weight or measure, but think the following is about right, but it 

 may in large orchards be used, no doubt, with a less proportion of 

 the corrosive, but for this I will not vouch. I have usually added
