Semn-. fly this year is attacking pbbatons .with avidity. When first noplants 1 affected should lie with one or'oilier of the underf ' "mentioned sprays. Bordeaux mixture lyK'n is one .of the most efficacious. This is mixing:4lb bliicsfono, GU) fresh • . ro'che lime, and fiOgal. water. Where . potatoes are attacked, Ibis is probably ' C.tKe l)est remedy, as spraying with this V ' mixtiire will ward'off the potato blight, ! :' ;'\vhich may attack the plants later on. r* .Irish blight is hardly likely lo bo at all prevalent t-liisiyear, unless the wea- • flier changes and we have more humid % atmospheric conditions than at present obtain;; For preparing this spray the ® : Agricultural' Department give the fol- "■ * lowing directions: —Dissolve 'lib sulV\* ''j-pliate of copper in Siigal. water, slake X 7% the; 51b lime slowly, and make up to )>; ■...25ga1;,- strain this milk of lime into Vthe>solution of copper, stirring briskly. !

This is made as ;V' : follows:—Kerosene 2gal., common soap " ' ; jib, boiling water Igal. Place the soap \ in'the water, which should by preferehce .be. rain-water. Hard water is \ «n'suital)lc, but if only such is to be 'v -v had, make it soft by adding some soda. " poil till the soap'is thoroughly (lis- '■.
