avail. Mr. Austin informs me that kerosene, as strong as the cabbage 
could bear, has been applied with no better effect. 
A communication to the society just named, from an experienced 
gardener, states that during the past season he saved his cabbages by 
diluting carbolic acid with lime-water. The proportion in which the 
two are mixed will be given in a. note as soon as the communication 
is published, being now in the hands of the printer. While I think 
it probable that success in this case was largely owing to careful cul¬ 
tivation and early-formed firm heads, yet this corresponds somewhat 
closely with the following experience related in the monthly reports 
of the National Agricultural Department for 1871. Mr. Quinn, the 
market-garden reporter for the New York Tribune, says that he made 
use of the following mixture: Twenty parts superphosphate made of 
slush acid, one of carbolic powder, and three of unslaked lime, mixed 
well together and dusted thoroughly into each head four times, at 
intervals of four days. This, he says, was effectual—the lime alone 
being of no value, and the carbolic powder alone destroying the cab¬ 
bage, but to this agent he appears to ascribe the efficacy of the 
mixture. 
Truf. J. H. Comstock, in an article to the Prairie Farmer of May 
20, 1879, makes the following suggestions: “The wholesale destruc¬ 
tion of the pupae gathered from the boards placed among the cabbage 
does not seem to me to be the best thing to do. As many of them 
are infested with the parasite, Pteromalus puparum , by destroying the 
chrysalids the parasites are also destroyed. The importance of this 
point is well illustrated by the following experiment. In a collection 
of sixty chrysalids of the Pieris rapoe made at Ithica, N. Y., fifty- 
seven were destroyed by this parasite before arriving at maturity.” 
“I should therefore recommend the collecting of the pupae from the 
boards, but instead of destroying them place them in a box covered 
with a wire screen or a piece of mosquito netting. The chalcis flies 
are so minute that upon maturing and emerging from the chrysalids 
they can readily escape through the meshes of the netting and go on 
with their work of exterminating the mischievous larvas; on the other 
hand the butterflies not injured by the parasite, being unable to escape 
from the box, can be killed or allowed to die in their prison. Another 
remedy I would suggest is the use of hot water, as this has been 
tried with success in many instances. Water heated to 140 degrees 
fahrenheit will not injure the plant and will destroy the worm very 
effectually. It should be applied by a watering pot so that the plant 
may be thoroughly drenched in all the infested parts.” 
The following statement from another corresnondent is found in the 
same paper: “It is said that cayenne pepper sprinkled over cabbage 
plants is a sure preventive of worms, destroying them and not injur¬ 
ing the plants. It would probably be more effectual if a light tinc¬ 
ture were made and the plants lightly watered with it. My experience 
with the green cabbage worm "was of benefit to my neighbors as well 
as myself. On their first appearance there were hundreds. I dusted 
black pepper over them before the dew was off. After the second ap¬ 
plication only twelve worms remained on 130 heads of cabbage. I 
sent them to bug heaven by rubbing turpentine on their backs with 
a feather and now our patch is entirely unmolested.” 
Mr. Saunders remarks (Can. Ent. Oct. 1878) that strong decoctions 
of cayenne pepper and smartweed have been highly recommended.
