with an opening at its base for a line and 

 plummet. The usual form of a trench for 

 drainage is shown under Drainage. The 

 broader spade A is used for making the 

 upper and larger part of the trench, and 

 the narrower spades i; and c for forming 

 the lower and smaller part in which the 

 drain pipes are laid. The tool D shows 

 the shape and form of the implement for 

 clearing loose earth from the bottom of the 

 trench along which the pipes are laid. 



Draining Materials. 



The materials employed for drains are 

 very varied ; brushwood, rubble, stones, 

 bricks, and pipes being all in use. In clay 

 countries it is no unusual thing to form 

 pipes with the clay itself, by inserting an 

 arched framework of wood, and withdraw- 

 ing it when consolidated. The best and 

 cheapest drains, however, are drain-pipes, 

 which are now obtainable everywhere on 

 moderate terms. 



Dredger for Lime and Soot. 



For caterpillars, slugs, &c., a dressing or 

 sprinkling of lime or soot is most useful, 

 either when applied to themselves when 

 visible or to the plants on which they feed 

 or the plants they frequent. Salt is also a 

 deadly poison to slugs. The difficulty that 



most people find is in procuring means for 

 the application of the powder. An old 

 flour dredger that is past 

 kitchen use will answer 

 the purpose admirably; but 

 if nothing of this kind is 

 available, a dredger can be 

 easily made out of a cylin- 

 drical tin can, as shown in 

 the accompanying illustra- 

 tion. At A the perforated 

 cover is shown in plan. 

 To make this, the cover 

 should be placed on its 

 outer surface on a piece of 

 hard wood or lead, \vith

most. Pmd the centre, and 

 with a pair of compasses trace some fine 

 circles, as shown in the illustration. Then, 

 with an old bradawl that has been sharpened 

 to a point, make holes in the tin along the 

 circles that have been described, driving 

 the bradawl point through the metal by 

 striking a smart blow on the handle with a 

 hammer.
