290 THE CULTURE 



be remembered that at the lafl tune of clean- 

 ing the hurdles, when the worms are ready 

 to Ipiji, the beds fliould be taken away, 

 otherwife they will make their pods among 

 the ftraw or ftl|^s, where their littei* would 

 foul them, ana there would be a lofs of 

 filk in drawing away the pods ; therefore, 

 at that time the worms muft be laid on the 

 hurdles, without any bedding under them. 



Thus far it f^emed to me neceflary to 

 enlarge on the fubje6l of keeping filk- 

 worms clean in a detach'd chapter, that I 

 might not too much interrupt the method 

 and order of the book ; and I thought it 

 a fubje<5l too material to be omitted, even 

 tho' only one ufeful rule of pra6life were 

 iuggefted by the whole chapter. 



Among fuch a multiplicity of precepts 

 and obfervations, fome things may poffibly 

 have efcaped my attention > one at prefent 

 occurs which is, that an equal continued 

 degree of warmth is what filk worms beft 

 thrive in, and this degree is about the 

 eighteenth of Reaumur s Thermometer, and 

 fixty feventh of Fabrenhaifs, for filk- 

 worms will without any detriment bear 

 fome variation above and below this de- 

 gree. I fliall only juil mention one thing 



more.
