FALL MANAGEMENT, 



THK FUMIGATOR. 



I am indebted to a communication from J. M. 

 Weeks, published on page 151 of the Caltivator for 

 1841, for this method. The description of the fumi- 

 gator that I constructed will vary a trifle from his, 

 but will retain the principle. I obtained a tin tube 

 four inches long, and two in diameter. 'Next, I made 

 a stopper of soft wood, three inches long, to exactly 

 fit one end of the tube when driven in half an inch, 

 and secured it by little nails driven through the tin. 

 Through the centre of this stopper I made a hole 

 one-fourth of an inch in diameter. To prevent this 

 hole filling up, the end in the tube was covered over 

 with wire cloth, made a little convex. The end of 

 this stopper was cut down to about half an inch, taper- 

 ing it from the tin. For the other end a similar piece 

 of wood is fitted, though a little longer, and not to be 

 fastened, as it must be taken out for every operation. 

 The outer end of this is cut down into a shape to be 

 taken into the mouth, or attac&ed to the pipe of a 

 bellows. (I fitted them in the turning lathe, but have 

 seen them fixed very nicely without.) It could all be 

 nAde of tin ; but "then it is necessary to use solder, 

 which is liable to melt and cause leaks.
