Swift Travellers.

| we talk a great deal about the speed
| OF our railway trains and of our ocean
| greyhounds, but we are apt to over
| look the fact that there are some swift
travellers where no rails have ever
been laid and no steamship has
steered her COURSE. The carrier pigeon
will fly at least thirty miles an hour,
and some have been known to travel
at the rate of sixty or even ninety
miles an hour. Wild pigeons often fly
hundreds of miles day to feed, re-
turning to their roosts at night,
Audubon says they travel mile a
minute s~> s. -.
Is Water-fowls, gulls, terms and petrels
literally fly on the wings OF the wind,
It surprised in a storm. They will rise
high in the air, facing a gale and
making little progress forward as
well as upward. Then they will sud
denly descend with rapid fight to-
ward one side Of the storm-swept path,
but falling off at the same time in the
direction of the blowing wind. Once
more they will sweep around and face
the storm, ascending heavenward, and
striking desperately out toward the
direction Of the storm, until finally
they work themselves to one side of
the storm center. ~ .- ~. =
During tremendous wind storms
birds may sometimes be seen fiying
overhead at a great height. When
this is noted it may be taken for
granted that the upper air is com
paratively quiet, and that the storm is
confined chiefly to the lower regions.
It is when the storm extends too high
up that they drift away with the wind,
or fly away on the edge of the hurri-
cane. Migrating birds fly over dis
tances SO great that they must needs
have great strength as well as great
speed in flight. . Bobolinks often rear
their young on the shores Of Lake
Winnipeg and like true aristocrats go
to Cuba and Porto Rico to spend the.
winter. To do this, their fight must
twice cover a distance of more than
$500 miles, or more than fifth of the
circumference of our earth each year.
The little redstart travels 1000 miles
twice a year. What wonderful mech

to propel itself through the air during

for it. sWims mile in less than two
minutes, and any horse could be left
behind in a long race, for the fish
can cover thirty miles in an hour
When leisurely ascending rivers, with
frequent rests in attractive pools, it
averages from fifteen to twenty-five
miles a day. In leaping, the salmon
can easily beat the horse, for salmon
have leaped up waterfalls twelve feet
high, and he prepares for a leap i1st
as a boy does, with a short, sharp run.
If the water at the foot OF the dan, or
fall is not deep enough to allow this
