148 HIGHWAYS AND BYWAYS. 
Swallows are now gathering in immense flocks, 
alighting on roofs of barns and houses and on telegraph 
wires, where they flutter and cliirp to one another in 
the most social way; they appear to congregate at pre- 
concerted times and places, compare notes in their bird

houses and the telegraph wires for several blocks. 
Three or four species of swallows fly and flock to-

tection. All the insect exterminators sold by druggists 
would weigh little in comparison with the work done 
by these industrious little birds, yet how many of them 
are yearly slaughtered by the thoughtless sportsman,
