The principal insects treated are the Wheat Midge, the Army Worm, the 

 Wheat Stem-maggot, the Bean Weevil, the Clover Cut- worm {Mamestra 

 <r(/o//»), and Cut-worms in general. We sympathize with Mr. Fletcher 

 concerning the poor quality of paper and press-work used in the Domin- 

 ion reports which we have seen, aud assure him that we consider his 

 reports worthy of much more attractive form. 



THE PYRETHRUM INDUSTRY. 



Welearii from the Calif or nia Florist and Garden for March, 1889, that 

 (luring the year 1888 there were imported into the United States from 

 Dalmatia aud other places between 200 aud 300 tons of dry Pyrethrum 

 flowers, while California's product was 52 tous. 



A NEW USE FOR THE FLUTED SCALE. 



A writer in a recent number of the Florida Disijatcli suggests that 

 inasmuch as there is a probability of overdoing the orange business in 

 Florida (as it is estimated that that State will in the next five years be 

 able to supply, a box of oranges for every man, woman, and child in the 

 United States), a good way to limit the production would be to intro- 

 duce the Fluted scale {Icerya pnrchasi) into Florida! 



CODLING MOTH NOTES. 



Mr. D. B. Wier, in the Orchard and Farm (California) for March, 1889^ 

 in a general article on " Orchard Work," in which he summarizes the 

 remedies for the Codling Moth, suggests that every large orchard should 

 have a store-house or packing-house or building that can be made moth- 

 proof, into whicn all api^les and pears should be taken as soon as gath- 

 ered. Packages of these fruits should never be left outside of this build- 

 ing over night. He suggests simply the covering of all openings in the 

 building with fine wire gauze and the use of as few windows as conven-. 

 ient. The moths issuing from the fruit will fly to the windows, where 

 they may be destroyed every morning. This suggestion is a good one, 

 as we have shown in our article on the Codling Moth in the Annual Re- 

 port of this Department for 1887, pages 97 and 98, where we quote the 

 experience of Mr. DeLong, of California, who killed upwards of 15,000 

 moths in this way. 



Prof. E. A. Popenoe gives a detailed account of his experiments in 

 spraying apple trees with arsenical combinations in the first annual re- 

 port of the Kansas Experiment Station, a review of which is published 

 in the Industrialist for April 20, 1889. His experiments seem to have 

 been carefully carried on aud comi)arisous made with uusprayed trees. 

 His best results were obtained with a mixture of 1 ounce of Paris green 

 to 20 gallons of water. By the use of this two thirds of the crop was 

 saved at the expense of damage amounting to 8^ i)er cent, of the foliage.
