APPENDIX II ANSWERS TO CIRCULAR. 393 



bam insisted, as well as I can remember, that the cotton-worm was wafted here during 

 times of high rains, from certain quarters of compass, from Central America or other 

 more southern countries, where it was always to be found, and where the cotton plant 

 grew perenially. My experience is, that during dry summers and falls, the worms 

 never appear early enough to destroy the plant before a fair crop is made. [Douglas 

 M. Hamilton, West Feliciana. 



The insect is 7iot affected by the weather. [Dr. I. U. Ball, West Feliciaua. 



When the worms appear, neither wet nor dry weather affects them any way. [John 

 A. Maryman, East Feliciana. 



MISSISSIPPI. 



Warm, cloudy and wet weather always favorable to the coming of the insect. [John 

 C. Russell, Madison. 



Rainy spring and summer always produces this worm. [J. W. Burch, Jefferson. 



I cannot say they are affected by weather. Some of the years mentioned as destruc- 

 tive years were just opposites, as for instance, 187 (5 and 1878; 1876 was cool and dry, 

 1878 wet and very warm. [C. F. Sherriod, Lowndes. 



Extremely heavy rains destroy some of the worms, and perhaps some of the moths. 

 The worms cannot endure exposure to the unobstructed rays of the sun in the warm 

 part of the day. The influence of these two causes is not large enough to be of much 

 importance. [C. Welch, Covington. 



1 think showery weather in June tends to increase their breeding considerably ; cool 

 weather at that time and later assists. The plant must be growing so that there are 

 tender leaves on the top of the plant to favor their increase. If not growing and the 

 leaves become toughened from hot dry weather the worms do not damage it. [Daniel 

 Cohen, Wilkinson. 



Cloudy and wet weather in July and August invariably brings the fly. If we have 

 a, seasonable July, nay one or two good rains and none in August, we always make fair 

 crops of cotton. [Kenneth Clarke, Chickasaw. 



The moth seems to delight in warm cloudy damp weather, leaving its retreat more 

 readily when the atmosphere is in that condition. In clear weather and hot sunshine 

 they keep very close until twilight, when they may be found flitting from plant to 

 plant. The larvae, like the moth, seems to prefer cloudy hot weather, but hot dry 

 weather does not seem to check their devastations. Heavy rain- storms certainly do 

 check them. Cool weather seems to retard their operations. [Dr. E. H. Anderson, 

 Madison. 



May and June very wet, cloudy, and moderately warm will invariably bring this insect 

 in such numbers that (the same conditions 1 continuing in July and August) the crop 

 will certainly be destroyed. Any careful observer can, by the close of June, any year, 

 at any given locality, decide whether the Aleliu can iucraise to such numbers as to 

 damage the crop seriously during the succeeding months. This has been done annually 

 lor the last thirty years without a single failure. [D. L. Phares, Wilkinson. 



Rainy weather and hot sunshine alternating. [VV. Spillruan, Clarke. 



I know from long experience and close observation that continuous rains in the 

 month of July bring to notice the worms. The winter has nothing whatever to do 

 with the appearance of this destructive insect. [George V. Webb, Amite. 



NORTH CAROLINA. 



Wet weather seems to produce them when it is very warm. [F. J. Smith, Halifax. 



SOUTH CAROLINA. 



When the worm does appear here, it is in a wet warm summer, and it appears first 

 in black soil, which is low and damp. In gray soil they never come until after they 

 have grown and been propagated on the darker soil. [Paul S. Felder, Orangeburgh. 



Moist and.cloudy weather is most favorable to the rapid development of the in- 

 sect. [J. W. Grace, Colleton. 



Dry hot weather is unfavorable to the growth, production, and activity of the 

 worm. [James C. Brown, Barnwell. 



TENNESSEE. 



So far as I have observed, the weather exerts a decided influence upon the cotton 

 caterpillar. [A. W. Hunt, M. D., Perry. 



TEXAS. 



Dry hot weather is unfavorable. [R. Wipprecht, Comal. 



The only effect is heat advances, cold retards maturity. [W. Barnes, Cherokee. 



Wet sultry weather most favorable to the increase of the worm. [S. B. Tackaberry, 

 Polk. 



I do not believe the weather has much to do with them, because this has been the 

 wettest year for a long time past, and they did very little damage in this part of the 

 country. [P. S. Watts, Hardin.
