ing millet at the same date as wheat may endanger the seed in 
some soils, but farmers have told me this season that they have 
raised millet planted that early. Some workers have suggested 
planting millet between the wheat and corn or about the corn field 
thus protecting the latter crop. This pest has but few enemies and 
given favorable climatic conditions increase almost without natural 
check. A predatory bug is said to prey upon it and among the 
birds it is claimed that meadow larks and black birds have a fond- 
ness for it in spite of its peculiar “bedbuggy” odor so disgusting 
to man, and the stomach of a single quail examined in Nebraska 
was found to contain over 500 specimens of this pest all eaten in 
one day. 
OUR EXPERIMENTS AD THE STADION: 
On May 28th the Agricultural Department of the Station com- 
plained to the Entomologist that the bugs were then threatening 
to seriously injure some experimental plats in the nursery. I 
found them then copulating and egg laying, which lasted as late 
as June 2nd. The wheat was young and the question arose as 
to how the plats were to be saved. On May 3tst, millet was 
planted around and between the plats. Carbon bisulphide was 
used June 2nd, canvas covered frames having been made to cover 
portions of the plats, and we having first tested it on other wheat ; 
the idea being that if we could by several applications kill off the 
bugs at that time on the wheat the young millet would attract 
other bugs which might be seeking food from the outside. The 
treatment was only partially successful and its use was aban- 
doned. The reader will understand of course, that the methods 
adopted here were practicable only when used on a small scale 
and could not be applied on large fields. It was then decided to 
use kerosene emulsion. We had found that one part emulsion to 
ten parts of water did not injure wheat upon which it was first 
tried. On June 21st and later the emulsion was used on the ex- 
perimental plats at the strength of one part to ten parts of water 
and an examination was made June 30th to note its effects. While 
some of the leaves around the roots appeared a little burned, on 
the whole the grain looked very well. A goodly proportion of 
the bugs were killed by this treatment. Upon July 23rd the emul- 
sion was again applied but to the outside rows only. On July
