out altogether.

"I don't care," said Caleb to himself, "for I have got the other half
of the salt-cellar;" and he went back for that. It happened unluckily,
however, this time, that, in pulling open the cleft which Raymond had
made in his maple pole, he pulled too hard, and split one side off. Here
was at once an end to all attempts to communicate fire to his chimney by
this method. So, after refitting the split part of his stick to its
place, once or twice, and finding that the idea of uniting it again was
entirely out of the question, he threw the broken piece away, and said
to himself that he must try Raymond's second plan.

He accordingly took the other large piece of bark, which was the one
which Raymond had used for his plate, and laid it upon the fire. As soon
as it began to curl, he laid the end of the stick close to it, on the
side towards which it seemed to be bending,--and in such a way that it
curled over upon it, and soon clasped it tight, as Raymond had predicted
that it would do. He then raised it in the air, and set out to run with
it, so that it should not burn out before he reached the place. But he
ought not to have run. It would have been far safer and better to have
walked along carefully and slowly; for as he ran on, jumping over logs
and stones, and scrambling up and down the hummocks, the top of the
pole, with the blazing roll of bark, was jerked violently about in the
air, until, at length, as he was wheeling around a tree, he accidentally
held the top of the pole so far that it wheeled round through the air
very swiftly, and threw the birch bark off by the centrifugal force: and
away it went, rolling along upon the ground.

The centrifugal force is that which makes any thing fly off when it is
whirled round and round.

Caleb did not understand this very well, but he was surprised to see his
roll flying off in that manner. He immediately took two sticks, and
tried to take up the roll with them, as one would with a pair of tongs;
but he could not hold it with them.

"Well, then," said he, "I must try the third way."

So he began to gather sticks, and put the ends of them upon the fire.
When they began to burn, he took up one; but as soon as he got it off
the fire, it began to go out, and he said that he knew that way to
kindle a fire never would do. In fact, he began to get out of patience.
He threw down the stick, and went off again after Raymond.

"Raymond," said he, "I _cannot_ make m
