At any time between the first day of November and the firstday of March of each season, all the apple, pear and quincetrees, in any orchard infested by codlin moth, should be care-fully scraped and all loose bark removed, as follows : Fig. 376. Provide some small ship scrapersand grind two of the edges to a con-cave curve (Fig. 376) so that they willfit the trunk of the tree better than astraight edge can (B and C, Fig. 376).Scrapers having a length of side offour inches will be large enough;. usehandles to suit. Procure a cloth madeof old sacks, or any material conven-ient ; spread on the ground aroundthe tree as far as the scrapings arelikely to fall; then commence on thetree as far up as there is any roughloose bark, and scrape it carefully examine and scrape all crevices in the bark or thoseformed in the crotches of the tree. Continue scraping until. REJfEBIES. 397 you reach the ground. This done, gather the scrapings care-fully off the cloth, so that they can be burned or otherwisedestroyed immediately. Be careful that you do not neglect gathering carefully thescrapings and destroying them, as on this point depends agreat deal of your success. By thus burning the debris takenfrom the trees the larvae hibernating in the debris are de-stroyed. B. After having completed scraping off the loose bark, thetrunk and limbs should be thoroughly washed or sprayed(providing the tree is only treated against the codlin moth).If the woolly aphis or scale insects are present, the whole treeshould be sprayed with No. 11 or No. 12, one pound of eithermixture to each gallon of water used. If .properly applied,this will destroy any larvte on the tree, and also produce anew smooth bark. See
