GRASSHOPPERS ON SUGAR BEETS AND TRUCK GROPS. ie | 
hold, usually about 1 gallon. While fresh, the wet fruity mash is very 
attractive to grasshoppers; but when dry or stale it is not eaten. 
The bait is applied by sowing it broadcast on the infested land late 
in the evening or early in the morning. Very early morning is to be 
preferred, as the grasshoppers are then just beginning to feed, and 
they have a longer time to eat before it dries than if it were applied 
at any other time. The bait should not be spread just before a shower, 
as rain washes the poison from the bran flakes, leaving them harm- 
less. Little of the bait is eaten after the first day, even in damp 
weather. Therefore several applications may be necessary to check 
damage by grasshoppers in badly infested fields, or to keep injurious 
numbers from drifting into a field. 
The amount of bait prepared by using the quantities of ingredi- 
ents given in the formula will sow 6 acres of heavily infested land. 
This makes the cost of one application about 25 cents per acre. 
Ordinarily this amount should be spread over about 12 acres, which 
reduces the cost to 15 cents per acre or less. When the bait is to be 
applied a small quantity of known weight should be mixed and 
sown that it may be ascertained how very little is required when 
only 2 to 4 pounds of bran are to be used to the acre. 
Neither domestie animals nor birds can secure enough of the poi- 
soned bait to kill them, if it is scattered evenly as directed. However, 
a few cautions regarding its use may not be out of place. It should 
never be placed in heaps or scattered thickly. The poison and 
mixed bait should be kept out of the reach of children and of domestic 
animals. Utensils used in handling the bait should be thoroughly 
scrubbed before being used for any other purpose. The dry, pow- 
dery poisons should not be exposed to the wind or handled roughly 
or carelessly. The bran and poison should be mixed with a spade 
or wooden paddle. If the hands are used for this purpose enough 
poison may be absorbed by the back of the hands and the forearms 
to cause severe intestinal cramps and diarrhea. However, the writer 
has never known poisoning to occur simply from sowing the wet 
bait barehanded. 
THE HOPPERDOZER. 
The hopperdozer is an old device for using kerosene, crude oil, 
or tar in catching grasshoppers and was developed during the migra- 
tory grasshopper years of 1874-1876. It consists of shallow sheet- 
iron pans, containing the oil or tar, which are mounted on low 
wheels or sled runners. An upright screen at the back catches the 
‘““‘hoppers”’ as the machine is drawn forward. 
The hopperdozer is simple in construction. (See fig. 11.) The pan 
is made by turning up 6 inches of the edge of a sheet of galvanized 
iron, 8 feet long and 30 inches wide. Two inches of the edge is then 
turned down over the pan to prevent slopping, and two partitions
