therefore omitted ; while still others are too complicated and expensive 
to warrant mention. A few words have still to be said concerning the 
mixture to be used, in connection with the lamps, for killing the moth. 
Almost any sticky substance, such as paint, tar, molasses, soap-suds, 
&c, will answer the purpose ; but the cheapest and most effective means 
is to half till the pan with water, and then pour in a tablespoonful of 
kerosene. The mixture can be strained off in the morning and used 
again. 
•A simple lamp, hist n ;.oe 1 y ( el. ( 1 nrh s Lt^is. of Ihamc, Tex. 
has lor some time been in use in the lields in the BrazOH River bottom. 
It consists of the usual shallow tin plate placed upon a board that is 
nailed to the upper end of a stake or post. In the middle Of this pan 
is placed a common kerosene lantern, large enough to burn the whole 
night, or ;it least the larger part thereof In 1878 the planters near 
Hearne, Tex., were nightly burning over 1,000 of these lamps during a 
period of several weeks. The coat of this lamp, with the tin pan, is be- 
fcweeen 30 and 10 cents, and the cost of burning it -one night about 1 
cent. One lamp is generally osed lor even ft vib acres where the land is 
level, but at shorter intervals wbeie it is rolling. 
u Ihc Mcfjucen Lamp. — This again does not mntci ially differ from the 
others so far mentioned. Patented by Mr. 15. v. McQueen, ol Manack, 
Ala. (No. l66124,July 27, 187.">), it consists of an ordinary lantern which 
is secured to the center of a shallow basin, beneath which is fastened a 
tube intended to lit on a post or stake. At the top of the lantern is a 
horizontal screen of tin, forming a re llectoraml serving also to precipitate 
the insects in the pan below. An illustration of this appears in Plate bX, 
Pig. 2, where represents its attachment to a stake, II is the pan, A the 
lantern, and 1) the reflector. The reflector not only throws the light, 
but the insects that ascend at the side of the lantern strike it and fall 
down into the pan. 
"Titr Uigel Lamp, — Invented and patented by Bfr. Mark Kigel, of Ala- 
bama (patent dated January 28, 1873), this lamp differs only In being 
made so as to hang by a ring, and in the lantern having in addition to a 
horizontal reflector several vertical ones. 
"There is auother class of lumps of a still simpler nature, consisting 
of a torch light, large enough to prevent its being extinguished by the 
wind, and placed in the middle of a tin pan. While cheaper than those 
with a steady light, they are decidedly less effective, and, moreover, 
they consume more oil. The simplest lamp of this class is a stout bottle 
tilled with kerosene and mounted with a wick. 
" The Walker Lamp. —This has been constructed by Mr. John E.Walker, 
of Winchester, Tex., and is represented herewith (Plate LX, Fig. 4). 
It consists of the usual tin pan placed on a post, and of a short, funnel 
shaped pipe soldered to its center. A second hollow tube of the same 
shape, inverted, is attached to the bottom of the oil reservoir so as to 
lit firmly over the first. The reservoir has at the top a raised mouth,
