FUMIGATION FOR DESTRUCTION OF THE RED SPIDER IN A 

 HOTHOUSE THIRTY FEET LONG AND SIXTEEN WIDE. 



Six ounces of flower of sulphur are sufficient for one fumi- 

 gation. The best mode of proceeding is to dissolve a lump 

 of soft soap, about the size of a walnut, in warm water, adding 

 to this some clay-water, made by working a lump of clay in 

 warm water until it becomes of the thickness of thin paint, and 

 then mix in the sulphur. When all are well blended together, 

 apply the mixture by means of a brush upon the sides of the flue ; 

 this must have been previously heated. The best time to apply 

 it is late in the afternoon, just previously to closing the house 

 for the night. 



FUMIGATION TO DESTROY GREEN-FLY AND TURIPS. 



" According to the size of the place to be fumigated, one or 

 more pieces of cast iron, one inch thick and three inches over, 

 are made red-hot — placed in No. 24 sized iron pots, on which 

 is put the tobacco — one pound of which is sufficient for three 

 heaters, in equal parts. The tobacco is so quickly consumed, 

 that the house is completely filled in a very short time, and 

 but little smoke can escape before the insects are destroyed. 

 The pure heat from the iron heaters prevents injury from gas ; 

 and as no blowing is required, there is no dust, it being only 

 necessary to put the tobacco on the heaters, and leave the 

 house." — Vide Gardener's Chronicle. 



RECEIPT TO DESTROY APHIDES. 



Syringe with tobacco-water two consecutive evenings — and 

 strong shag tabacco is the best for this purpose. Three-quarters 

 of a pound to a gallon of hot water makes a liquid perfectW 

 efficient. It is applied with a hand-syringe ; and the operator, 

 after battering them one way to the end of the wall, returns and 

 batters them again the reverse way — by which means, scarcely 

 a leaf is missed. My trees are covered with canvass, projecting 

 from galvanized iron coping ; and I choose a dry evening for the 

 operation, applying the mixture about six o'clock, p.m., and 

 drawing down the canvass soon after the operation, and remov- 

 ing it the next day in case of sunshine or rain, in order that the 

 effects of the liquid may not be too soon dissipated.
