Thefe which my laft fly laid looked at fir II large and full, but in a few days they began to (hrivel and be indented in the mid- dle, as did all the reft. However, I folded them ,all up in feparate papers and laid them by, to fee if any would hatch the fpring fol- lowing. The' male fly is lefs than the female, but his colours are brighter and more beawtiful. In the fpring of the year 1767, I examined the eggs, and found them all dry, and not likely to produce worms ; from whence I concluded th...ey had not been impregnated by the males. This was a disappoint- ment to me. But being ftili of opinion, that they might be propa- gated, I determined to make another trial with more caution and cir* cumfpettion. Accordingly, L fet out in •fearch of cocoons, and gathered feveral of them both from the fwamps and upland. Thofe from the iwamps I got chiefly oft! the alder; thofe from the upland, off On the native Silk-Worms of Norths-America* •ff the wild crab-tree, and the tiburnum or blaclc haw butties* Thcfc pods I placed as I had the Others, before my garret window, where the fun might fhine on them, asfoon as it arofe.
