7 
degrees get into and clog the blast-pipe (bp), which, 
on account of its form and position, is difficult to clean. 
It is true that the nozzle (n) and the grating (g) in 
the Bingham occasionally get somewhat choked ; but, 
when this occurs, they are cleared with great facility. 
The question, “Which is the best smoker?’’ is often 
asked, and for this reason I have fully stated my ob- 
jection to an appliance which stands <in high favour 
with many; and without doubt, the Bingham and the 
Clark are both exceedingly effective ; for, if the 
Bingham only have a fire-tube wide enough,* both 
may be made to burn almost anything — peat, rotten 
wood, chips, wooden laths, are all excellent. I gene- 
rally use brown paper, which is with us a waste pro- 
duct. Some of this, roughly torn, rolled up, packed 
pretty closely into the fire-box, and lighted (as it may 
be instantly by a match) either top or bottom, will 
smoulder for hours. The fuel is introduced in the 
Clark at the door (d), and into the Bingham by the 
removal of the coned nozzle (;;). If the smokers 
are stood as in Fig. 4, they burn freely, because in 
the Clark the leak at the door (d) supplies sufficient 
air, while in the Bingham the blast-pipe not entering 
the fire-box, but acting like a steam injector, gives 
room for the admission of a current. This excellent 
arrangement in the Bingham also saves the blast-pipe 
from clogging with the tarry residues. To reduce the 
rate of combustion, stand the smoker on the bellows 
bottom ; and to extinguish, plug the nozzle. 
The manner of using the smoker will be hereafter 
* No fire-tube smaller than 2|in. in diameter can be recommended, 
except for very small apiaries.
