spread over the plowed field in small handfuls at a distance of 
every few feet. The Paris green should be used at the rate of one 
pound to a hundred gallons of water and the grass distributed late 
in the day so that it will not wither before the worms attack it at 
night. Of course ground must be sprayed which will not soon be 
eaten over by stock. If desirable the poison may be mixed in a 
barrel of water and the green material dipped into it and then dis¬ 
tributed over the ground. The water must be constantly stirred 
to keep the poison in suspension. 
If fresh vegetation is not available arsenic bran mash may be 
used. This is made by the method used for grasshoppers. The 
U. S. Department of Agriculture gives the following directions 
for preparing this insecticide: “Paris green, arsenoid, white 
arsenic, or in fact any arsenical can be used for poisoning this 
bait, and in its preparation, on account of the weight of the poison 
and the fact that it soon sinks to the bottom of the water when 
stirred, it is best to mix the bran with water and sugar and then 
add the poison. The proportions are two or three ounces of sugar 
or a similar quantity of glucose or molasses to a gallon of water 
and a sufficient amount of bran (about a pound per gallon) to 
make, when stirred, a mixture that will readily run through the 
fingers.” About one pound of poison should be used for every 
fifty pounds of bran. Often syrup may be had at the sugar fac¬ 
tories at a very much cheaper rate than the cost of the other 
sweetening materials. Scatter this preparation over the fields late 
in the day, preferably when the ground is bare, either before the 
seed is planted or before it comes up. Dr. John B. Smith is 
authority for the statement that a field may be cleared in forty- 
eight hours by this means. If the beets have already begun to 
come up the bait should be placed in little heaps of a tablespoon¬ 
ful each along the rows. 
A dry mash composed of Paris green 1 lb., equal parts of bran 
and middlings 20 lbs. is recommended by Dr. Forbes. 
Hither of the bran preparations are dangerous to fowls and 
these should be kept off the fields for several days.
