Directions for Obtaining and Applying the Chinch-bug 
Infection. 
Infected bugs will be sent to. anyone on application. 
The infected bugs received from the Station should be used 
to start infection-boxes in the following manner : 
CHARACTER AND LOCATION OF INFECTION-BOX. 
Make a box of seven-eighths inch material (matched white 
pine is best), about 24x36x6 inches. Make the cover tight-fit- 
ting, so that the bugs cannot readily escape. Weather-strips 
tacked about the upper edges of the box, so that the cover 
presses tightly against them when closed, will be found of ser- 
vice in keeping the bugs in. A heavy chalk-line drawn inside 
the box on the sides near the upper edge will greatly assist in 
keeping the bugs in the box. 
It would be well for each farmer to have two boxes, and, after 
the first box has become well started, he should start the second 
from infection obtained from the first. 
Place the boxes so as to exclude them from the sun and wind. 
A basement room is a good location. 
TO START THE INFECTION IN THE BOXES. 
Sprinkle the boxes thoroughly with water inside and out. 
Place an even layer of garden-soil in the boxes, half an inch 
deep. ‘The soil should be free from leaves or anything liable to 
decay. Sprinkle the soil until it is moistened through, but not 
muddy. Put athin layer of green wheat or corn over the soil 
in the boxes, and distribute over this, at regular intervals, five 
or six of the white-fungus-covered bugs. Now put into the 
boxes healthy bugs from the field until they are somewhat 
crowded, but not packed over one another. Lastly; close and 
fasten down the cover. 
Examine the boxes daily, and sprinkle the sides and soil as 
often as they appear to be getting dry. Do not, however, make 
the soil muddy. As soon as the white-fungus-covered bugs be-
