Snails

Platform protectors against snails, slugs, sow-bugs (or wood lice) and crawling (not flying) insects may be made by placing boards on tins for legs which stand on greased bricks or in pans containing a little  oil of any kind. Seed pans and flats placed on these  platforms will be safe from visitation and the seedlings they contain from attack so long as the greasiness continues or the oil remains. 

Slugs and snails often do serious damage to plants during wet seasons and in damp situations. Lime and  wood ashes will control them. These materials exhaust their supplies of slime, weaken and kill them.  They may also be trapped with bits of freshly cut  carrot placed in damp spots at evening and visited  in early morning. Poisoning their food with arsenate  of lead is also effective.
