chiefly extracted) are hatched in fifteen days, and the little 
whitish caterpillars or moth-worms proceeding therefrom im¬ 
mediately begin to gnaw the substances within their reach, 
and cover themselves with the fragments, shaping them into 
little hollow rolls and lining them with silk. They pass 
the summer within these rolls, some carrying them about 
on their backs as they move along, and others fastening 
them to the substance they are eating; and they enlarge 
them from time to time by adding portions to the two open 
extremities, and by gores set into the sides, wliich they 
slit open for this purpose. Concealed within their movable 
cases, or in their lint-covered burrows, they carry on the 
work of destruction through the summer; but in the au¬ 
tumn they leave off eating, make fast their habitations, and 
remain at rest and seemingly torpid through the winter. 
Early in the spring they change to chrysalids Avithin their 
cases, and in about twenty days afterwards are transformed 
to winged moths, and come forth, and fly about in the 
evening, till they haA^e paired and are ready to lay their 
eggs. They then contriA-e to slip through cracks into dark 
closets, chests, and draAA'ers, under the edges of carpets, in 
the folds of curtains and of garments hanging up, and into 
various other places, Avhere they immediately lay the founda¬ 
tion for a noAv colony of destructive moth-Avorms. 
Early in June the prudent housekeeper Avill take care 
to beat up their quarters and put them to flight, or to 
disturb them so as to defeat their designs and destroy their 
eggs and young. With this vieAv Avardrobes, closets, draA\"- 
ers, and chests Avill be laid open, and emptied of their con¬ 
tents, and all Avoollen garments, and bedding, furs, feathers, 
carpets, curtains, and the like, Avill be removed and exposed 
to the air, and to the heat of the sun, for several hours 
together, and Avill not be put back in their places Avithout 
a thorough bmshing, beating, or shaking. By these means, 
the moths and their eggs Avill be dislodged and destroyed. 
In old houses, that are much infested by moths, the cracks
