till it comes within their reach. They no sooner per- 

 ceive the frefli food than they abandon the rubbifli be- 

 low, and creep through the mefhes, so as to fix them- 

 selves upon the leaves ; then by gently raising the frelk 

 baflcet, and drawing out the board below, (which 

 ought to be made to slip out, like the slip bottom of 

 a bird's cage,) you get ofF all the excrements and de- 

 cayed leaves, without incommoding the worms in the 

 smallest degree; and along with the litter you will draw 

 off* an inch or two in depth of the foulest mephitic 

 vapours. To get entirely rid of these, the board, 

 when thus taken out, fhould be carried without 

 doors, and there cleaned ; and the slip board immedi- 

 ately replaced to receive all the excrements and offals. 

 After it is replaced, the wire frame that had been ele- 

 vated a little, may be allowed to descend to a convenient 

 distance above the board, without touching it. Thus 

 will there be left a vacant space for the mephi- 

 tic air to fall below the worms, so as to allow them to 

 inhabit a wholesome region of the atmosphere. 



When a frefli supply of food is to be given, before 

 cleaning, the wire frame ought to be let down as close 

 to the board as can be safely done, and another wire 

 bottomed frame put over it, with frefti leaves, as before 

 described. When the worms have abandoned that in 

 their turn, let the slip board, together with the low- 

 er wire frame, be drawn out and removed ; and so on 

 afi often as nccefsary. To admit of this alternate 

 change, every table, consisting of one slip board, 

 ought to have two sets of wire-bottomed frames of 

 the same size ; the slip board to be always put into 

 its plsjce immediately after it is cleaned, and the wire
