HIS fpecies appears in Great-Britain 
near twenty days before the martin, or 
any other of the fwallow tribe. They 
leave us the latter end of September ; and for a 
few days previous to their departure, they af- 
femble in vaft flocks on houfe tops, churches, 
and even trees, from whence they take their flight. 
It is now known that fwallows take their winter 
*' V* 
quarters in Senegal\ and poflibly they may be 
found along the whole Morocco fhore. We are 
indebted to M. Adanfon * for this difcovery, who 
firft obferved them in the month of OSiober , after 
their migration out of Europe , on the Ihores of 
that kingdom : but whether it was this fpecies 
axone, or all the European kinds, he is filent,

The houfe fwallow is diftinguilhed from all 
others by the fuperior forkinefs of its tail, and by 
the red fpot on the forehead, and under the chin. 
Its food is the fame with the others of its kind, 
infe&s \ for the taking of which in their fwiftefl: 
flight, nature hath admirably contrived their fe- 
veral parts ; their mouths are very wide to take 
in flies, &c. in their quickeft motion ; their wings 
are long, and adapted for diftant and continual 
flio-ht: and their tails are forked, to enable them 
to turn the readier in purfuit of their prey. This 
fpecies builds in chimneys, and makes its nefl: of 
clay, leaving the top quite open.

T H E martin is inferior in flze to the 
former, and its tail much lefs forked. 
The head and upper part of the body, 
except the rump, is black glofled with blue : the 
bread, belly and rump are white : the feet are co¬ 
vered with a fliqrt white down. This is the lecond 
of the fwallow kind that appears in our country,

It builds under the eaves of houles, with the lame 
materials, and in the lame form as the houfe Iwal- 
low, only its nefl: is covered above, having only 
a fmall hole for admittance. We have allb feen
