EXPERIMENT 20.—BLACK PEPPER. 
Applied the ground article of commerce copiously to two heads of 
cabbage. 
Result.—I could not see that it affected those which came in contact 
with it, and all continued to feed as though no application had been made. 
EXPERIMENT 21.—CARBOLIZED LIME MIXTURE. 
Mixture of carbolized lime 1 part, quick lime ? part, gypsum 20 parts. 
Dusted mixture on two plants. 
Result.—Twenty-four hours after, the worms were crawling about on 
the leaves, feeding, aud although some of the powder adhered to their 
bodies, I saw no fatal results. 
EXPERIMENT 22.—TAR WATER. 
Sprayed on plants. 
Result.—None apparent. 
EXPERIMENT 23.—TOMATO WATER. 
Steeped leaves of tomato vines, and applied strong decoction. 
Result.—As in preceding. 
EXPERIMENT 24.—ARKANSAS INSECTICIDE.* 
Placed 24 larve on leaf of cabbage, and dusted both leaf and worms 
thickly with the insecticide, at 10.25.a.m., August 25. The leaf and worms 
were confined under a glass. 
Kesult.—At 10.25 next day, they seemed to be feeding from some parts 
of the leaf not covered with insecticide. August 27, they did not seem 
to relish the leaf with the insecticide thereon, but found enough not at 
all or thinly covered to keep them alive. This is not of practical 
utility for large plants, but might do on those very young. 
EXPERIMENT 25.—ARKANSAS INSECTICIDE. 
Tested this thoroughly on plants, with results like those on leaf un- 
der cover. In this experiment the larve were watched closely for a 
period of four days. 
EXPERIMENT 26.—SOLUBLE PINOLEUM.+t 
Solution of 1 part pinoleum to 40 parts water, sprayed copiously on 
plants in garden, Angust 25.

A sample of this ‘‘soluble pinoleum” was also sent to our agent at Cadet, Mis- 
souri, Mr. J. G. Barlow, who reported in brief, as follows: ‘‘ Have experimented a 
little with the soluble pinoleum sent to me by your desire from North Carolina. I 
found that a solution of one part to 10 of water was not too strong for larvx of
