John Kilburn, as he looked up and
saw the holes.

Mrs. Kilburn and her daughter were loading the extra guns the while, and
handing them to the men and boys, who kept up such a rapid fire that the
Indians came to the conclusion that there were a large number of men in
the house.

"We shall soon be out of bullets," said Mrs. Kilburn.

A thought came: why not catch the bullets that were coming through the
roof? The balls had nearly spent their force when they came through, and
they hung up a blanket, with thick folds, which stopped them entirely;
and the girl, gathering them as they fell harmlessly upon the floor, put
them into a ladle, melted them, and ran new bullets, which soon were
whizzing through the air, and doing damage to the enemy.

All through the afternoon the fight goes on, the Indians aiming at the
loop-holes. Their bullets pepper the logs around them. One comes in, and
inflicts a ghastly wound in Mr. Pike's thigh, but the Indians do not
know it, and the brave defense is kept up till the Indians, foiled in
all their efforts, defeated, with several of their number dead and many
wounded from the volley fired by Colonel Bellows and his men, and by
those in the house, set Mr. Kilburn's wheat on fire, kill his cattle,
bury their dead, and slink away, not having taken a scalp or a prisoner.
They have only wounded one man.

When everything goes well with the Indian he can be very brave, but when
the tide is against him he quickly loses courage and becomes
disheartened, and so Captain Philip made his way back to Canada, very
much crest-fallen at the repulse received at the hands of two men, a
woman, two boys, and a brave-hearted girl.

About Combustion.

BY

W. J. ROLFE, A.M.

Combustion is only another name for burning, and burning in all ordinary
cases is _oxidation_, or union with oxygen, one of the gases that make
up our atmosphere. It is a _chemical_ change; that is, one by which we
get a new substance entirely unlike any of the substances united. Common
salt, for instance, is formed by the chemical union of a yellow,
bad-smelling gas and a soft silvery metal. When coal and wood are
burned, the chief products of the union with oxygen are carbonic acid
and water. The former is a colorless gas, and the latter is in the form
of invisible vapor, and both go up the chimney and mix with the outer
air. The ash
