Summer Birds of Passage. ATL 
arrives at extremes; in consequence of which, 
every wanderer of the feathered tribe has the 
power of selecting a suoimer residence in the 
temperate zone which is agreeable to its 
feelings and appetite. The different kinds of 
these birds can naturally subsist in places 
where the spring has made less or greater 
advances ; for the redstart precedes the swal- 
low, and the swallow precedes the cuckoo. 
This is the reason why the different species 
travel in distinct parties, resembling the le~- 
gions of a numerous army marching in the 
same direction; the whole body being in mo- 
tion together alternately to the north and 
south. I shall close the Essay with a table 
exhibiting the order of this procession in 
Westmoreland. The first column contains 
the names; the second gives the times of 
migrating northwards, which is when the 
winter birds depart, and the summmer visi- 
tors arrive ; the third gives ‘the times of 
migrating southwards, that is, when the sum- 
mer birds depart, and the winter visitors 
arrive. .
