like the Barn Swallow, under the eaves of barns and other build- 
ings. The gourd-shaped nests of both species may occasionally be 
seen in peaceful commingling on the same barn. 
The last member of the Swallow family to arrive from the 
south is the Bank Swallow, Riparta riparta. This is the least 
pretty of our swallows, also the smallest. It is brownish-gray 
above, and white below, with the exception of a dusky band across 
the breast. It can be recognized at once by its nesting habits. 
What it loses by its lateness in coming, it makes up doubly by its 
energy in nesting No sooner has it come than it digs into 
the nearest sand bank, without any delay after its long 
journey from the south, and this, without taking into consider- 
ation the nearness of boys or other evil agencies, that will at once 
render unvailing its best efforts. In a sand pit at Ottawa, when 
its nests were destroyed by the breaking down of the sand walls 
by the men hauling the sand away, they would nevertheless 
set to work digging new tunnels in the same banks. When 
ground was broken for the foundations of the new Victoria 
Museum at Ottawa, these Bank Swallows came in numbers, bored 
into the sides of the excavations and did not in the least mind the 
men working a few feet away from their nests. By the dusky 
band across their breast they can be told from the Tree Swallow ; 
their twittering is also more rasping than that of the other swal- 
lows. 
The sixth and last swallow, the Rough-winged, Steleidopleryx 
serripennis, is found in some places in south-western Ontario only. 
It is much like the Bank Swallow, but may easily be distinguish- 
ed from it by the dusky gray of throat and breast, being the 
darkest of the smaller swallows. 
Now a reader may ask, What about the Chimney Swallow ? 
Where does that comein? Answer: The Chimney Swallow is 
no swallow at all but a Swz/t, belongs to an entirely different 
order, far removed from the swallows in classification and by 
structure. But, since it is associated with the Swallows in the 
popular mind, we will here introduce it. 
The Chimney Swift, Chelura pelagica, is an inhabitant of 
our cities like the Purple Martin, and, like the Cliff Swallow, has 
adapted itself to and made use of the changed conditions wrought
