generally the best time for dusting, but the evening is also suitable. When the weather 

 is calm and the foliage damp, the powder adheres, and is not wasted by being blown 

 away. Dusting should take place on the first appearance, preferably in anticipation of 

 blight or disease. Be careful to cover the affected parts, or those usually attacked. If 

 the lower side of the leaves be the seat of infestation, expel the powder upwards. A 

 thin coating is all that is required, yet there is need to coat all parts evenly. 



The Sulphur Duster (Boite a Houppe), Fig. 94, is handy for dis- 

 tributing very fine powder. It consists of a tin tube, perforated at one 

 end with rather large holes-, through which worsted is threaded, partly 

 closing them, yet allowing sulphur to b^ evenly distributed. It is filled 

 from the opposite end, closed by a rotary lid. It is cheap, simple, 

 and useful. 



The Indiarubber Distributor, Fig. 95, was designed for distributing 

 the powder known as Anti-Blight, as was another invention, the Malbeo 

 Bellows, Fig. 96, for use on a larger scale. A straight delivery pipe can be attached, 

 and is preferable for dusting vines and fruit trees overhead. These appliances answer

For use on a large scale La Torpille, an adaptation of the 

 Knapsack pump, for distributing sulphur and other powders, 

 has proved highly satisfactory in France. By means of a 

 handle depending in front of the operator from a beam over 

 the shoulder the pump is worked, and the powder in the 

 vessel, which holds 22 pounds of sulphur, is agitated, and 

 delivered through the spout in a " cloud," as shown,
