but the character of the soil is exceedingly variable, and crops grown; 

 continuously upon a soil draw out one or more of its nutritive principles ; 

 consequently, it can only be reinvigorated by returning to it those ele- 

 ments removed in the crops. 



506. Q. What shall I apply to my cabbage to kill the green worm ? 



A. The cabbage worm is a green caterpillar, feeding on nearly all 

 broad-leaved vegetables, especially cabbage, cauliflower and lettuce. It 

 is the larvse of a white butterfly of European origin. Paris green will 

 poison these caterpillars, but, except in the very early stages of cabbage 

 growth, it is unsafe to apply so poisonous an article to a plant which 

 might enfold the poisonous compound within its leaves and kill those who 

 afterwards ate the plant. Pyrethrum has been found effective. 



507. Q. Are there several ways of preparing kerosene emulsion ? 



A. Yes ; several ways of arriving at tlie same end — as take : One part 

 sour milk, two parts kerosene, thoroughly mixed by rapid agitation till 

 the combination forms a creamy liquid. To this add fourteen parts water, 

 and apply by an injector, or dash over the vines with a broom. The 

 emulsion may also be made with : One quart soft soap, one quart kero- 

 sene, two quarts water mixed by forcible agitation, and diluted with 

 sixteen quarts of water. Apply to the plants forcibly with a syringe. 



508. Q. Can I kill the cabbage louse? 



A. The Downy cabbage louse is a mealy, soft-bodied insect, sometimes 

 appearing in thousands, swarming* like bees upon the leaves of young 

 cabbage, Brussels sprouts and cauliflower. It can be checked off by the 

 application of kerosene emulsion, but it is diflicult to drive it off entirely. 



509. Q. Can the ravage of the onion fly be stopped ? 



A. Equal parts of wood ashes and land plaster dusted very thoroughly 

 on the young plants will generally drive them off. An application of 

 some efficiency is, one part of Paris green, mixed with forty or fifty parts 

 of land plaster or flour.
