 this keeps them as yet too cold, or that 

 your hurdle is fo vv^ide that they drop 

 through, or any other inconvenience at- 

 tends this, you may remedy it by laying 

 fheets of coarfe paper, but free from every 

 thing ofFenfive to the worms, round the 

 ^dgQ of the cake of fibres, and as the cake 

 extends with the growth of the worms, by 

 the fame degree you may draw out the 

 papers, flill leaving fome under the edge 

 of the cake, till you find no inconvenience 

 follow from taking them quite away. A 

 little fine hay, fpread thin over the empty 

 part of the hurdle round the cake of fibres 

 on which your worms lie, might anfwer
