University, Mississippi, from which is quoted the following: “In the 
southern part of the State reports show that on account of injury by 
Boll Worms and shedding, due to wet weather, the cotton crop will 
be short from 30 to 40 per cent. of last year’s yield. * * * In the 
northern section the Boll Worm did no material damage.” It may fur- 
ther be added that upon application to Mr. George E. Hunt, chief sig- 
nal officer U.S. Signal Service, New Orleans, Louisiana, for weather 
crop bulletins and the names of observers who had reported much 
damage to cotton by Boll Worm last season, he replied that no material

damage was done from that source and none had been reported by any 
of the volunteer or other observers. From this information as also the 
facts shown by the preceding tables it is quite evident that the depre- 
dations upon cotton by Boll Worms have been greatly overestimated. 
If the statements of planters living in the regions where observations 
were made are accepted, the Boll Worm was fully as numerous if not 
more so than in previous years. Nearly all agreed that the damage was 
fully up to the average, others thought it above the normal, but none 
estimated it as being lower than usual. These statements together 
with the almost daily reports obtained from interviews that *‘ one-fourth 
or one-third of the crop was being ruined” (?) led to above careful stud- 
ies. The results simply show that on the whole the planters fail to dis- 
tinguish the Boll Worm ravages from those of other insects, from phys- 
iological phenomena of the cotton plant, and lastly, from some of the 
fungoid diseases. In order to assist the planters in this matter a few 
observations have been added at the close on “ Other insect ravages 
easily confused with those of the Boll Worm.”
