INJURIOUS INSECTS OF I909Q AND IQIO. IOI 
THE STATE AND FEDERAL INSECTICIDE LAWS. 
Two years ago Minnsota had no law governing the manufac- 
ture and sale of Paris green or arsenate of lead. In 1909 the 
Entomologist assisted in framing the following bill, which became 
a law through the action of the Legislature at its thirty-sixth 
session : 
A BILL FOR AN ACT TO PREVENT DECEPTION IN THE SALE OF 
“PARIS GREEN” AND OTHER INSECTICIDES.

Sec. 4. The label required by this act shall clearly and distinctly state 
the name and residence of the manufacturer of the “Paris green” or other 
insecticide, or the distributor thereof, or of the party for whom the same is 
manufactured and show the name, and with substantial accuracy, the per-
