up their work, and am not familiar with their habits or history. As, like the 
Colorado potato veetle they have a habit of feigning dead and falling to the 
grounl when disturbed, I think they might be caught in nets by holding them 
under the vine and giving a sudden jar to it. At one time in the summer I dis- + 
covered the leaves of some Concord grapes infested with a dark catapillar about 
one-third of an inch long, which was eating the leaves full of holes. Before I could 
take time to secure some of them in order to watch their transformation before 
they had entirely disappeared. Probably they were the larvie of the beetle. 
I do not know that bed bugs are injurious to the horticulturist, only as they 
keep hired hands from getting sufficient rest at night, and consequently they 
take more in daytime. 
Cabbage Worms. 
A green and yellow striped caterpillar about 144 inches in length when fully 
grown, has been very destructive to cabbage, eating the leaves away and even 
into the hearts, causing premature decay. I have not had time to study them 
-up, but think they are the larva of a yellowish white butterfly (Pieris rape, or 
P. oleracea) that is seen hovering about the garden in considerable numbers. 
There appeared to be several broods of them during the summer. Sprinkling 
the cabbage with a moderately strong brine would probably be beneficial. Thou- 
sands can be destroyed when they are small, before they have wandered from the 
leaf wpon which they have hatched. A few minutes spent daily in looking for 
and destroying them will prevent their doing any serious damage. 
Considerable damage was done to the cabbage in the fall by another insect 
that eats holes im the leaves, riddling them like a seive. The caterpillar is little 
more than one half inch long, of a greenish color, and thickened in the middle. 
Dr. Fitch has described it in N. Y. Report of 1853 Page 874, as the Cabbage 
Moth (Cerostoma brassicella.) When disturbed, the. caterpillar drops from the 
plant to suspend itself by means of a silken thread. The pupa is formed in a 
silk-lke cocoon woven upon the leaves, and as it is but a few days before the 
perfect insect emerges, probably more than one brood is hatched out in a year. 
Inoticed them quite numerous last fall in the garden of Mr. L. Chase of Minne- 
apolis. I think salt water would be a good remedy. My patch was entirely 
cleared of them by a flock of blackbirds, but they scratched the cabbage to pieces 
considerably in getting at them. 
JOHN L. HARRIS. 
MR. HOLLISTER’S PAPER. 
Mr. Hollister’s paper was then called for, and read by the writer, 
After the reading, a vote of thanks was tendered and a copy 
requested for publication. The following is the paper. 
GROWING SEEDS FOR MARKET. 
It is not intended by this paper to convey the impression that seed growing is 
an easy and sure horticultural horse to ride to sudden competence. Neither is 
it intended to show that any one can succeed in the business, any more than an 
essay detailing the workings of any commercial enterprise would guarantee busi- 
ness success to any person undertaking it.
