OF THE STATE ENTOMOLOGIST. 19 



conclusions which Mr. Glover deduces from them correspond, how- 

 ever, not only to the mass of testimony elicited by my own corre- 

 spondence, and found in the clippings sent by Mr. Langdon, but to 

 the experience had of this insecticide in the more northern States, as 

 already detailed in these pages. I give these conclusions in Mr. Glo- 

 ver's own words: 



Of the seventy returns reporting actual experiment, a large pro- 

 portion, at least four-fifths of all, declare the success, either full or 

 partial, of the application of mixtures of Paris green or other arseni- 

 cal compounds, when they are properly applied. Some are content 

 with the simple declaration that it is an efiectual remedy. Where it 

 is most generally used it is most approved. In New Iberia, La., where 

 a machine that will powder 15 to 18 acres per day is in use, it is said 

 that fifty planters have found it successful. In Wilkinson, Mississippi, 

 where a simple compound of Paris green and flour was used, "rows 

 treated with the compond were healthy and vigorous, while neglected 

 rows beside them were destroyed." In Landry, Tex., "one application 

 of Paris green in solution resulted in ten additional bales in a field of 

 35 acres, over the rate of production in other fields where none was 

 used. " A similar result is reported from Montgomery, Tex., by the 

 use of Paris green mixed with lime or plaster, or eveji fine sand, where 

 " a neighbor has picked already ten bales of 500 pounds each from 13 

 acres, while freedmen on the same farm lost their whole crop by re- 

 fusing to use it." The correspondent in Worth county, Ga., declares it 

 ''was death to everything that eats theleaves that have been sprinkled." 

 Some correspondents enjoin the necessity of repeated applications to 

 meet the appearance of successive broods of worms, as enough are 

 left after the most careful application to perpetuate the noxious race. 

 In some cases, caution is suggested not to make the application after 

 the bolls are open, lest it become "' dangerous to picker and ginner. " 

 In the cases of failure mentioned there appears no evidence that the 

 application was properly and persistently made, and with a pure article 

 of Paris green. In some cases where it killed both worms and plants, 

 it is very evident that the proportion of Paris green was too large or 

 applied too heavily. " * * % * * 



It has, in short, proved most satisfactory, wherever properly and 

 intelligently used. 



The following item will give an idea of what it costs to use this 

 remedy on a large scale. Mr. J. R. Maxwell, of Alabama, writes to 

 the Southern tanner : "'I have been successful in the use of Paris 

 green on the Cotton-worm. I had one hundred acres of cotton on 

 swamp land that would have been ruined, but on their first appear- 

 ance I commenced on them. I put eight hands on mules, with two- 

 gallon watering pots, and had ten more hands and two wagons engaged 

 in keeping them supplied with water and poison, and went over my 

 cotton twice ; up one side of a row and down the other, going thus 

 twice to each row. Poison, labor and all cost me about three hundred 

 dollars. It has saved me at the very least twenty bales of cotton. I 

 used the poison by putting to each canful of water half a tablespoonful
