wliich is placed a lighted glass lantern. The moths being attracted by the 

 light dash against it and fall into the pan and are destroyed before deposit- 

 ing their eggs upon the tender leaves of the plants. I have never used the 

 lantern on my plantation, the above described poison did the work so com- 

 pletely, that I thought it unnecessary to try any other remedy, bnt I have 

 no doubt that it will prove beneficial if properly used. 

 Hoping some of the above items may be of benefit to the cotton growers, 

 I remain, very respectfully,

Dear Sir, — In answer to your circular of December Ist, would say I 

 have planted cotton since 1865. I have had worms on my cotton every 

 year since, except 1870. They have never done me serious injury except in 

 hot damp seasons. They have generally appeared about middle of July, 

 and when injury has resulted from them, it has been when they have in- 

 creased to the third crop, about 15th of August to the 10th of September. 

 I can form no idea as to whether we will have them or not any season, 

 their appearance being the first indication. 



I have used Paris green and the "Texas Cotton Worm Destroyer," both 

 are serviceable. I like the " Texas Cotton Worm Destroyer " best, it is much 

 cheaper and more easily prepared for use. It is however almost impossible 

 to protect a large crop with either, the time is so short, they destroy it so 

 rapidly and you must have dry weather for either to be elFective. 



Very respectfully, 



J. W. HARROW.

 J. Curtis Waldo, Esq. 

 Dear Sir, — Your communication has been received and in reply I 

 would state that I have been planting cotton for 30 years, and the first 

 season that I remember to have seen the worms, was in the year 1840. The 

 caterpillar requires a wet season to accumulate, as such weather is de- 

 structive to their natural enemies, the ant, and also an insect called the 

 Ichneuman, which feeds ravenously upon the cotton worm. After the 

 butterfly, the first signs of the approach of the cotton worm is in the shape of 

 a green worm, which is generally called the for© runner. I think they leave 

 the germ on the plantation, though they are capable of migrating. I have 

 used arsenic in dry weather with good results, but if a rain should follow 

 the application, in a few hours it will destroy all good effect. I have also 

 used the Paris green to a considerable extent, this is the most popular 

 remedy, but I have found it non-effectual under continual rain. The 

 remedy should be used when the first worm is seen. I have during the 

 past season used the arsenic and Paris green both in solution. The great 

 difficulty lies in applying the poison, as it should be done by machinery, 

 so that the man or horse would not come in contact with the poison. I 

 think a light cart could be so constructed as to sprinkle 3 rows at a time 

 and as lightly as desired. By this a cart could be made to sprinkle 30 acres 

 in a day. 



I think Paris green mixed with flour and applied with a sifter is the 

 most effectual and lasting manner of applying the poison, though of course 

 it is the most expensive. 



If the poison was used when the fore runner makes his appearance, and 

 every planter could be forced to use the poison, then I have no doubt but 

 the worm could be entirely exterminated, but where one man uses the 

 remedy and his neighbor does not, it keeps up the presence of the worm, 

 ready to devour several times during the season. 



Yours, respectfully, 



WM. V. KEARY.
