APPENDICES. 271 



73 degrees, tlieir transition would be too rapid, and their 

 productiveness would be lessened. On the other hand, 

 if the temperature be below 66 degrees, the development 

 of the moths is tardy, and their produce equally falls 

 below the due proportion. 



The moths should begin to issue from the cocoons in 

 about fifteen days. The female deposits her eggs upon 

 sheets of paper, or strips of linen, which are then hung 

 in a cool situation, and when dry are preserved in an 

 airy place, and securely shielded from damp and vermin, 

 that premature hatching may be avoided in the winter 

 months. 



Some fair specimens of cocoons were shown me a 

 short time since by an Englishman, who spoke very 

 sanguinely of what might be done in Bermuda with the 

 silkworm. 



THE END.
