Fumigating apparatus . — The glass vessel should 
be wide at the neck, more so than in those bottles

of being closed with a cork, it should have a glass 
stopper. It should close hermetically, and it 
should be screwed fast with a vice or screw. This 
vessel, thus constructed, is more useful and conve-

Hotte, or panier — a basket for strapping on the 
back, to transport the worms of equal width from 
top to the bottom ; of a close texture, to prevent 
any dung, &c., from dropping out. (Fig. 3*4.) r j . 0

Frames for placing the moths upon . — These

be changed when dirty. These frames may be 
used for carrying leaves in or about, and should 
have a handle such as that of the portable wooden 
trays. (Fig. 267)
