AND ORNAMENTAL PLAITS 
MISCELLANEOUS FEEDERS 
APHI1DAE 
Indiana C. R# Cleveland (August 21): There have continued to "be many 
reports of serious injury to flowering .plants of various kinds, 
especially asters, "by root lice. Previous examination in many 
r of these cases has shown a common species to he the corn root 
aphid. Anuraphis maidi~ra.dicis Forties, but another species has 
been observed which has not yet been identified. Trouble from 
this source is apparently steadily on the increase £n the State* 
Infestations of root lice are always accompanied by conspicuous 
colonies of ants and most of our correspondents assume that the 
ants are doing the damage. 
SNAILS 
California Weekly News Letter, State of California, Vol. 7, No. 17 (August 2-J) : 
Snail control has been extended with success to ridding nurseries 
of this pest, according to R« D. Hartman, Superintendent of the 
Nursery Service of the California Department of Agriculture, 
The common garden snail, Helix asnersa, is considered a troublesome 
pest in some parts of the State. It attacks many ornamental plants 
in gardens and nurseries. The measure Recommended for the control 
of snails, as given out by the California Department of Agriculture, 
is to first spray the premises in the evening with water, to bring 
the snails into activity. Then mix 1 pound of calcium arsenate with 
16 pounds of wheat bran, either, dry or with the addition of about 
1 gallon of water. This bran mash is then thrown under buildings, 
among flowers, or any place inhabited by the snails. 
Eight hundred pounds of this poisoned-bran mash was scattered 
in Beverley Hills Nurseries and 250 pounds on the Hollenbeck 
Estate, with satisfactory results.
