. 70 ANNUAL REPORT. 
the blackcaps. Some like the Mammoth Cluster, but it is too 
tender. The Seneca is the richest flavored blackcap. 
Pres. Smith. J think the Ontario has an equally good fruit, 
and is about the same as to hardiness. 
Other Insects, and Remedies. 
Mr. Kenney asked concerning certain insects, especially the lice 
on tender shoots of apple trees. 
Mr. Brand. Myr. Barry’s receipt is tobacco-water, dipping the 
branches into it. i 
Pres. Smith. A solution of soap-suds is an effectual remedy for 
most insects. It fixes the Tent Caterpillar. 
Mr. Hollister. Is the term ‘‘Canker Worm,’’ applied to the 
‘¢Currant Worm,’’ correct ? 
It was decided not. 
Plant Lice. 
The Natural History of the aphides or plant lice was here dis- 
cussed, relating to which the following is copied from ‘‘ Harris’ 
Insects Injurious to Vegetation:”’ 
“The winged plant lice provide for a succession of their race by stocking 
the plants with eggs in the autumn, as before stated. These are hatched in 
due time in the spring, and the young lice immediately begin to pump up 
sap from the tender leaves and shoots, increase rapidly in size, and in a 
short time come to maturity. In this state, it is found that the brood, with- 
out a single exception, consists wholly of females, which are wingless, but 
are in a condition immediately to continue their kind. Their young, how- 
ever, are not hatched from eggs, but are produced alive, and each female 
may be the mother of fifteen or twenty young lice in the course of a single 
day. The plant lice of this second generation are also wingless females, 
which grow up and have their young in due time; and thus brood after 
brood is produced, even to the seventh generation or more, without the ap- 
pearance or intervention, throughout the whole season of a single male. 
This extraordinary kind of propagation ends in the autumn with the birth 
of a brood of males and females, which in due time acquire wings and pair; 
eggs are then laid by these females, and with the death of these winged 
individuals, which soon follows, the race becomes extinct for the season.” 
Ants. 
Mr. Sias. Are ants friends or foes to the horticulturist ? 
Mr. Dart. When they loosen up the ground into a mound they 
may do injury, but I think not in any other way.
