402 REPORT UPON COTTON INSECTS. 



SOUTH CAROLINA. 



They never appear in dry weather. [Paul S. Felder, Grangeburgh. 



Undoubtedly yes. [James W. Grace, Colleton. 



Wet summers do favor its multiplication. [James C. Brown, Barnwell. 



TENNESSEE. 



Yes, if the rains are not too heavy. [A. W. Hunt, M. D., Perry. 



TEXAS. 



Wet summers certainly do favor their multiplication. [O. H. P. Garrett, Washing- 

 ton. 



Yes; heavy rains injure tho insect. [R. Wipprecht, Comal. 



They do. [S. B. Tackaberry, Polk. 



They do not. [W. Barnes, Cherokee. 



Probably ; but I see when they make their appearance, whether wet or dry, they de- 

 stroy all the plants before they stop. [P. S. Watts, Hardin. 



Yes. [H. J. H. Brensing, Bowie. 



A warm, damp summer, without much heavy rain, is the most favorable to its multi- 

 pliation. [J. M. Glasco, Upshur. 



Only by causing luxurious growth of the plant, while a dry year would make the 

 leaves tough. [P. S. Clarke, Waller. 



Yes, for the reason that the young worms will find during such seasons plenty of 

 acceptable food in the tender leaves. As soon as these get hard and tough in conse- 

 quence of dry weather the worms can no longer subsist on them. [A. Schroeter, Bur- 

 net. 



In August, if the summers have been wet and the growth of the plant unusually 

 large and full of sap. [Samuel Davis, Hunt. 



Yes. [W. T. Hill, Walker. 



They do. [ J. H. Krancher, Austin. 



I cannot say it does; although it was very wet before they appeared in 1846. [C. 

 B. Richardson, Rusk. 



Undoubtedly. [A. Underwood, Brazoria. 



Wet summers are moat favorable for their multiplication. [Stephen Harbert, Colo- 

 rado. 



Yes. [Natt. Holman, Fayette. 



Wet summers have always favored its development and increases its ravages in this 

 locality. [J. W. Jackson, Titus. 



QUESTION 2 d. Effect of different kinds of weather on the eggs. 



ALABAMA. 



Damp and cloudy weather increases the worms. [Dr. John Peurifoy, ] 



The only effect of weather on the eggs is that produced by heat, retarding the hatch- 

 ing or expediting it as the temperature is increased or lessened. Wet~or dry does 

 not affect them only so far as the temperature is influenced by it. [P. T. Graves, 

 Lowndes. 



Hot, clear weather does not seem to favor the propagation of the insect, while 

 warm, cloudy weather seems to favor it. [R. F. Henry, Pickens. 



I do not know ; yet believe wet weather favors their hatching. [R. S. Williams, 

 Montgomery. 



Have noted no change made on the eggs by the weather. [John D. Johnston, 

 Sumter. 



I doubt whether the weather affects the eggs, unless very cool weather does to some 

 extent prevent their hatching. [ J. N. Gilmore, Sumter. 



We are of the opinion that hot, dry weather is most favorable for hatching the eggs. 

 [J. S. Hansberger, Bibb. 



Hot, moist weather is beat suited to hatching of eggs. [ J. A. Callaway, Mont- 

 gomery. 



Dry, hot weather not favorable to the hatching of eggs or increase of worms. 

 [J. D. Dreisbach, Baldwin. 



Extreme dry weather on sandy lands does retard their progress. I think tho reflec- 

 tion of the heat upon the eggs has a tendency to destroy them, whereas on bottom 

 lands the plant protects the egg. [James M. Harrington, Monroe. 



Hatch sooner in wet weather. [Knox, Minge, and Evans, Hale. 



As the eggs are generally deposited on the under side of the leaf and on the more 

 dense part of the stalk, without any positive knowledge on the subject, I am inclined 

 to the opinion that after they are deposited too strong rays of the sun upon the leaf
