cannot fly, and are therefore obliged to run in^ 

 to the woods s but then the moor-berries and 

 bilberries are ripe, from whence they are 

 abundantly fupplied with food. Whereas the 

 young do not moult the firft fummer, and 

 therefore, tho' they cannot run fo well, are 

 able to efcape danger by flight. 



The reft of the birds who feed upon infedls 

 migrate every year to forreign regions, in or- 

 der to feek for food in a milder climate -, while 

 all the northern parts, where they live well in 

 the fummer, are covered with fnow. 



Infects in the winter generally lye hid with- 

 in their cafes, and are nouriflied by the fur- 

 rounding liquor like the foetus of other ani- 

 mals, from whence at the approach of fpring 

 they awake, and fly forth to the aftonifhment 

 of every one. 



However all animals which lye hid in win- 

 ter, do not obferve thefe laws of falling. Some 

 provide fl:ore-houfes in fummer, and autumn, 

 from which they take what is neceflfary, as 

 mice^ jays^ fquirrels^ bees,
