" Mr. Riley, a St. Louis, Missouri, Services Rendus a La Viticulture 

 Francaise, 1873," encircled by " Ministere de TAgriculture et du 

 Commerce." 



The following is Mr. Riley's acknowledgement : 



St. Louis, Feb. 23, 1874. 

 Emile Karst, Agent Consulaire de France : 



My Dear Sir. — Your favor of to-day is at hand. Knowledge, to the 

 seeker after it, brings with it a reward far higher and more lasting than 

 any outward token. Yet am I gratified to receive this testimonial of 

 appreciation from the French Republic ; because it shows that, while 

 endeavoring, as a servant of the State of Missouri, to do what lies in my 

 power for the advancement of agriculture within her borders, my efforts 

 have been appreciated elsewhere. It illustrates that science — the true 

 interpretation of nature's workings, and mighty lever to civilization and 

 progress — is not local, but sheds her bright beams among all nations. It 

 proves that the discovery of any fact tending to promote the comforts 

 and conveniences of human existence, or, as Bacon so tersely expresses 

 it, hiimanis comviodis insefvire, belongs not to one State alone, but to the 

 world. Yours respectfully, 



C. V. Riley, State Entomologist.

 vine-growers as showing the good effect of an application of soot for the 

 destruction of the grape-vine root gall-louse. However, not having tried 

 the soot ourselves, we can only give the experience of others, and add 

 that Dr. Erni, formerly chemist to the Department of Agriculture, in a 

 letter from Berne, Switzerland, has also highly recommended the use oi^ 

 soot for the same insect. 



" M. Rogier, mayor of Poule Gard, exhibited to the central society of 

 agriculture the results obtained by the use of soot in the treatment of 

 vines attacked by the phylloxera. A young vine attacked by this insect 

 in 1869, was treated with soot put at the foot or root of each stem, in the 

 quantity of a half kilogram, (about one and one-tenth of a pound.) The 

 vine recovered. The following years all the stems which composed it 

 were smoked with soot. This vine has a remarkable vigor, while the 

 neighboring vines were dead or seriously injured. All vines treated with
