of destroying these insects, was offered, in the summer of 
1840. About ten years ago I observed them in gardens 
at Cambridge, and then made myself acquainted with 
their transformations. At that time they had not reached 
Milton, my former place of residence, and have appeared 
in that place only within two or three years. They now 
seem to be gradually extending in all directions, and an 
effectual method for preserving our roses from their at- 
tacks has become very desirable to all persons who set any 
value on this beautiful ornament of our gardens and shrub- 
beries. Showering or syringing the bushes with a liquor, 
made by mixing with water the juice expressed from to- 
bacco by tobacconists, has been recommended; but some 
caution is necessary in making this mixture of a proper 
strength, for, if too strong, it is injurious to the plants; 
and the experiment does not seem, as yet, to have been 
conducted with sufficient care to insure safety and success. 
Dusting lime over the plants when wet with dew has been 
tried, and found of some use; but this and all other reme- 
dies will probably yield in efficacy to Mr. Haggerston’s 
mixture of whalg-oil soap and water, in the proportion of 
two pounds of the soap to fifteen gallons of water. Par- 
ticular directions, drawn up by Mr. Haggerston himself, 
for the preparation and use of this simple and cheap appli- 
cation, may be found in the ‘ Boston Courier,’.for the 25th 
of June, 1841, and also in most: of our agricultural and 
horticultural journals of the same time. The utility of 
this mixture has already been repeatedly mentioned in this 
treatise, and it may be applied in other cases with advan- 
tage. Mr. Haggerston finds that it effectually destroys 
many kinds of insects; and he particularly mentions 
plant-lice of various kinds, red spiders, canker-worms, and 
a little jumping insect, which has lately been found quite 
as hurtful to rose-bushes as the slugs or young of the 
Saw-fly. The little insect, alluded to, has been mistaken
