«74 ox REAHING SILK-WORMS IN SCOTLAND. June 8 



continued for a night or two ; for a few nights longer, 

 it was covered with a baiTmat ; and afterwards was 

 ■fuffcred to remain in the garden by day and night, 

 without covering, j^t tlie time I placed thele in the 

 garden, I placed others (a fom.ewhat greater number) 

 in the dwelling houi'e ; botli colonies were fed with the 

 fioie kind of food, which was moltly the leaves of the 

 white mulberry, at the fame time", and in a propor- 

 tionable quantity, and were treated alike in every par- 

 ticular. During their growth, there wa^-- no dilterni- 

 blc dift'eren,ce between them ; they went through their 

 feveral changes, and began to fpin about the fame pe- 

 riod ; indeed the firtlthat they fpun was in the frame in 

 the garden. 



"The weather, during the laft three week?, was very 

 ■wet, and during the ixibole time unfe-afonahly ^old. 

 As fcon as I cbferved one of them in the frame bfgiu 

 to fpin, I took the frame within doors, as the weather 

 was fo wet ; that had it reinamed in its former fitua- 

 tion, 1 (hould not have been able to have attended to 

 the fpinning pf the worms, \vithout great inconve- 

 nience*" 



No difference in the quality, &c. of the filk pro- 

 duced was remarked. 



By means of this portable frame, therefore, filk- 

 'R'orms, in this cli^tiate, can be allowed to enjoy the 

 "benefit of the open air, which is fo conducive to their 

 lic'-ilth, as well as to that of the parfons who attend 

 them, while, by having a proper place provided for 

 their reception, theyxian be removed thither with eafe, 

 -whenever circumfta^ices Qiali render it neceffary. 1« 

 thefe frames, a perfon could with eafe remove twenty 

 thoufsnd of them at once ; and by a proper apparatus, 

 with handles, two perfons could take awav at leaft a 

 Lundred and fifty thou'fand ; fo that in cafe of a thun- 

 der itor-n, the whole might be removed into a place of 

 fafety in a few minutes. 



On feme future occafion, this fubjeft fliall be re,-. 

 i'umcd.
