 rufhes were put round the bottom of this 

 w^edge, fo as to keep the lower part from 

 dropping, and the ends ofthe rufhes were 

 drawn upwards, between the fides of the 

 drain and the wedge, it would be an im- 

 provement to this lafl method. Where 

 either of thefe methods are made ufe of,
