CHIMNEY SWALLOW. Crass IL. 
to turn the readier in purfuit of their prey. This 
fpecies, in our country, builds in chimnys, and 
makes its neft of clay mixed with ftraw, leav- 
ing the top quite open. It lines the bottom with ~ 
feathers and graffes: and ufually lays from four to 
fix egos, white fpeckled with red; but by tak- 
ing away one of the eggs daily, it will fucceffively 
lay as far as nineteen, as Doctor Liffer has expe- 
rienced. It breeds earlier than any other fpecies. 
The firft brood are obferved to quit the neft the 
laft week in Fume, or the firft in Fal: the laft 
brood towards the middle or end of Auguft. The 
neft being fixed five or fix feet deep within the 
chimny, it is with difficulty that the young can 
emerge. They even fometimes fall into the rooms 
below: but as foon as they fucceed, they perch 
for a few days on the chimny top, and are there 
fed by their parents. Their next effay is to reach 
fome leaflefs bough, where they fit in rows, and 
receive their food. Soon after-they take to the 
wing, but ftill want fkill to take their own prey. 
They hover near the place where their parents are 
in chafe of fies, attend their motions, meet them, 
and receive from their mouths the offered fufte- 
nance. 
It has a fweet note, which it emits in 4ugufe and 
September, perching on houfe tops.
