hn the Natural Hiftory .of Selborne, a book of 
great merit, lately publifhed, the author fays, that 
on the 26th of November, his neighbour faw a 
Martin in a fheltered bottom chacing flies, the 
fun then fhone warm; that on the 4th of Novem-_ 
ber he faw feveral Houfe Martins playing all day 
ng over his fields. He obferves, that from the 
htuation of the Martin’s neft againft a perpendi- 
cular wall, it requires great effort, and judgment, 
firmly to ix the foundation that the fuperftructure 
ay he fecure. For this purpofe the bird clings 
with its claws, and ufes its tail for a fupport like a 
Woodpecker ; and that the materials may not fall 
Dy their weight, in a foft ftate, the intelligent ar- 
chite& advances its work flowly, building only 
inthe morning, and devoting the reft of the day 
‘to amufement, and the chace of infe@ts.
