possible. The importance of this will be appreciated when it is remem- 
bered that all the worms which mature on this corn and produce moths 
will furnish an additional supply to infest cotton and at the same time 
reduce the number trapped by the corn planted for that purpose. The 
corn cut for fodder should be disposed of in such a way as to insure the 
destruction of the worms found in the plants when cut. Each planting 
of corn which is to act as a trap should be planted soon enough to be 
in good condition for deposition as each brood of moths makes its appear- 
ance. This would require about three plantings for the northern por- 
tions of the cotton belt, -and probably four in the southern. 
The three plantings should occur about the first days of June,' July, 
and August, respectively, and be cut whenever the worms are nearing 
maturity, to be sure to prevent their escape. By this method the 
least possible number of worms reach maturity. This consequently 
reduces their ravages on cotton later in the season to a minimum. This 
minimum is the most that can be hoped for, no matter what may be the 
remedial or preventive measures resorted to. This method would 
furnish a great source of fodder, and would tend to diversify Southern 
agriculture, a result greatly to be desired. 
LIGHTS FOR ATTRACTING THE MOTHS. 
Most of the experiments with lights for trapping the moths have 
proven unsatisfactory so far as economic results are concerned, but 
have been suggestive in that they have clearly marked out what will be 
necessary to make the use of lights more efficient. 
While at Shreveport, Louisiana, in company with Dr. A. R. Booth, 
two kinds of patented lamps were taken into a large field of cotton to 
test their relative values and also to determine if possible the ease 
with which the moth could be attracted to lights. The lamps were 
lighted at 6:30 p. m. Quite a number of moths were seen flying about 
in the field as we passed through it, but up to half an hour after sun- 
down but few insects of any kind were attracted. From that time 
until 8 to 9 p. m. insects of nearly every description were captured, but 
no Boll Worm moths. Sometimes a moth would be seen to approach 
the lamps but was more interested in feeding and depositing, always 
passing by or around without apparently noticing the lamps. 
The lamps had been placed on pedestals high enough to bring them 
above the level of the top of the cotton plants, hoping thereby to 
attract moths from greater distances. In the mean time it was noted 
that the moth seldom attained to such a height during her flights about 
the cotton plants. Accordingly, on the evening of August 8, the same 
lamps were taken into the field, but placed so as to meet the habits of 
flight of the moth. This placed them at least on a level or a little 
below the plane of the top of the cotton plants. It was found that 
more moths approached and came nearer the lamp, and one was caught. 
In most cases, judging from the flight and actions of the moths, the lamps
