12 FARMERS’ BULLETIN 131. 
to discover the army worms before they have a chance to become 
full grown and spread over the entire farm. When the worms are 
discovered at work do not lose a minute, but attack them vigorously 
by means of the measures outlined in the foregoing pages. 
(2) In case the worms are crawling in a body, surround them with _ 
a furrow or ditch and crush them with a log drag as they fall 
into it. . 
(3) Poison them by spraying crops not intended for forage pur- 
poses with 1 pound of Paris green to 50 gallons of water, or with 
2 pounds of arsenate of lead to 50 gallons of water. In case the 
Paris green is used on tender plants, like corn, 2 pounds of freshly 
slaked lime should be added to 50 gallons of the mixture. This 
is to prevent burning the tender plants. Where spraying is not 
practicable, the use of the poisoned bran bait, mentioned on 
page 10 of this publication, is strongly recommended.
