benumbed in great frosts. But in the month of 

 March and the beginning of April, they speedily 

 grow large, and cut a great number of the filaments 

 of wool, to feed and clothe themselves. 



Q. How are the winged moths known? 



A. There are seen upon the fleeces of wool, or in 

 other places, little cases, about a line in diameter by 

 four or five lines in length, and rarely six ; they are 

 a little swelled in the middle, and opened at the two 

 ends. There is a moth in each of these cases, which 

 keeps him under shelter, because he is clothed only 

 with a white, thin, transparent, and delicate skin : 

 the winged moth throws out one third of the length 

 of his body from his case, by the one or other end, 

 for it can turn in the middle, at the place where it is 

 the largest : it can also come out almost wholly. 

 There remains only the hinder part of the body and 

 the two hind legs, which are attached to the case, in 

 such a manner, that the caterpillar can draw it after 

 him, while walking by the means of his other legs, 

 It has only one third of its body without the case, 

 when it cuts off the filaments of the wool ; and 

 turns itself round in different directions, to seize a 

 greater number of them. It is fed by the sub- 

 stance of the wool, and uses it to make and en- 

 large his case ; it on this account partakes of the 

 colour of the wool, of which it eats. There is no 

 doubt, there has been, and still are winged moths 

 in the wool, when their excrement is seen, scat- 

 tered underneath. It consists of little dry and angu-
