The same statements made in regard to ‘Slug Shot” will apply to 
this mixture also. 
“SMITH’S VERMIN EXTERMINATOR.” 
This substance, advertised to kill every species of worm, bug lice, 
etc., and selling at the rate of 5 cents per box, is composed of partly 
air-slaked lime, treated with about 3 per cent crude carbolic acid and 
colored with a pink dye. Even if this compound contained 50 to 60 
per cent instead of 3 per cent of carbolic acid, its value as an insecti- 
cide would be extremely doubtful, but as it is, it is worthless. 
LICE EXTERMINATORS. 
Besides the insecticides usually spoken of in agricultural bulletins, 
attention is called to certain others. These are the lice killers on the 
market, a number of which are not worth the boxes they are put up in. 
“P, D. Q.”—One lice and flea exterminator analyzed in this labora- 
tory and selling at the rate of 25 cents per box, ‘‘P. D. Q.,” was found 
to contain about 15.5 per cent sulphur, a very small amount of some 
volatile substance that possessed the odor of naphthalene, and other 
higher coal-tar products, and 80 per cent of what appeared to be only 
common earth. 
“Instant Louse Killer.””—Another sample, selling at 25 cents per box, 
is ‘Instant Louse Killer.” This consists of a very small amount of 
tobacco, a large amount of partially air-slaked lime treated with a 
small amount of the higher products of coal tar, and a large amount of 
what appears to be clay. 
‘“‘Lambert’s Death to Lice.”—Still another sample, ‘‘ Lambert’s Death 
to Lice,” and selling at 25 cents per box, was analyzed. It is a mix- 
ture of tobacco with a small amount of lime, which appeared to have 
been treated with the higher products of coal tar. Either through 
negligence in cleaning the tobacco or on purpose a large amount of 
sand is present. 
It will at once be seen that all three of these lice killers are frauds. 
The first, it is true, does contain sulphur and a substance like naphtha- 
lene, each of which is good in driving away vermin, but it also con- 
tains 80 per cent of worthless earth for which we are paying at the 
rate of 20 cents per pound. The second contains nothing that will 
kill vermin except tobacco, and some of the higher products of coal 
tar, and these are present in such small quantities as to be practically 
of no use. The third contains enough tobacco to perhaps be of some 
value, but the same amount of good tobacco as in the sample could be 
bought for one third as much as the cost of the ‘*‘ Death to Lice.” 
ROACH DESTROYERS. 
Other preparations that are very extensively sold are the roach 
destroyers. These usually appear in two forms, as powders and
