the worms beginning to die in about twelve hours after application. In 

 forty-eight hours they did no further damage, and in about sixty hours 

 all were dead, while the plants remained fresh and green. On some small 

 patches where the compound was not applied, the forms were eaten up as 

 clean as if swept by afire. I consider that you have by far the best pre- 

 paration yet discovered for the destruction of the cotton worm, cheap, 

 portable, and efficacious.

COL. D. D. WATERS MAKES A CONCLUSIVE AND COMPARATIVE 



TRIAL. 



Clear Creek, Texas, Sept. 15th, 1874. 



Messrs. Preston & Robira : 



The worms having made their appearance all over my field of cotton, I 

 used your Texas Cotton Worm Destroyer on five rows in the centre, on one 

 side of the five rows arsenious acid dissolved in boiling water, and on the 

 other side Paris-green and flour, mixed with the solution of arsenious acid ; 

 I failed to destroy the worm, the cotton being entirely destroyed. Your 

 compound as well as the Paris-green mixture killed the worms, with the 

 very important difference that on the portion to which the Paris-green 

 mixture was applied it caused the cotton to shed its holU and squares. The 

 five rows to which the Texas Cotton Worm Destroyer was applied there 

 was no shedding, and the cotton continued to make until frost killed the 

 plant. I do not hesitate in saying that your compound is perfect in every 

 respect. 



Yours truly, 



D. D. Waters. 



Col. Waters is well known to all Texans as one of the first gentlemen of 

 his section of country. 



We now present a letter to the patentees of the Texas Worm Destroyer 

 from Judge William J. Jones, a gentlemen of much reputation in the 

 agricultural and literary world. In early life Judge Jones was for many 

 years the editor of the leading journal in Mobile, and since he has devoted 

 himself to planting has been a frequent contributor to leading agricultural 

 and political papers. He was the first to introduce the culture of sea- 

 island cotton into the State of Texas, and is in all respects abundantly able 

 to speak knowingly of all that pertains to the culture of cotton. 



Virginia Point, Texas, August ith, 1874. 

 To Messrs. Preston & Robira: 



I take great pleasure in responding to inquiry with regard to my experi- 

 ment with your Cotton Worm Destroyer on my growing crop of cotton, 

 On the first appearance of the worms I used Paris-green to exterminate
