86 REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 



(4) Early iu June the winds changed their course from east and southeast to south 

 and southwest. The caterpillars present did no harm whatever for full three months. 



Now, let us note the seasons from June to 10th September, when, at this latter date, 

 the caterpillars began to destroy the crops. 



The season from June to 15th July was dry, and the winds south and southwest. 



A rainy season began on the 15th July. We had daily rains until 19th August. 

 The winds continued to come from south and southwest all the rainy season. The 

 caterpillars did no harm in this rainy season, although they were alarmingly present. 



The rain ceased 6 days to begin again on the 25th August. 



The winds veered on the 25th August, or about that day, from south and southwest 

 to east and southeast, and by 10th September all the foliage had been stripped from the ' 

 cotton. 



The summary of these facts is that (1) early in June after a dry May, distinguished 

 by the prevalence of east and southeast winds, the caterpillar appeared ; (2) the cat- 

 erpillar did not then eat the crop, and contemporaneously with its advent the winds 

 changed from east and southeast to south and southwest ; (3) a rainy season put in 

 15th July and was excessive until 19th August, and the winds were south and south- 

 west, and the caterpillar though present did no work ; (4) the rains began again 25th 

 August and the winds were then, for the first time since May^ east and southeast, and 

 by 10th September the caterpillar had destroyed the crop. 



There were two seasons of east and southeast winds only, one in May followed by 

 the caterpillar, another from 25th August to 10th September followed by the cat- 

 erpillar. 



The caterpillar was present from June until 25th August, but did no work, and in 

 that time the winds were south and southwest. 



What effect has the course of the winds on the character of the growth of the cot- 

 ton plant ? and what character of growth in the cotton plant is favorable or unfavor- 

 able to the sustenance of the caterpillar f 



My observation is, the prevalence of east and southeast winds is followed by a rich, 

 juicy, sappy, heavy foliage, never that which precedes a liea.Yj fruitage of hlooms and 

 holls ; and that the prevalence of south and southwest winds is followed by small, 

 pale-green, sharp-pointed foliage, favorable to heavy fruitage of blooms and bolls. 



I have also noted that the caterpillar destroys the rich foliage much more greedily 

 than he does the hard pale-green foliage. 



It is a common remark that a " worm year is never a cotton year, even if the worm 

 did not destroy the crop." 



I never saw a good yield of blooms and bolls with the winds from easjb and south- 

 east. — J. W. DuBoSE, Pihe Eoad, Montgomery County, Alabama.
