So they heat the tire hot, and put it upon the wheel in that state.

Then when it cools it shrinks, and binds the whole wheel together with a very strong grip." "But if they put it on hot, it will burn the wood," said Marco.
"Yes," replied Forester, "it will burn the wood a little.

They can not help that entirely; but they stand ready with water, to pour on, as soon as the tire is in its place, and so cool it immediately, so that it does not burn the fellies enough to injure them." "What are the fellies ?" asked Marco.
"They are the parts of the wooden rim of the wheel.

The rim is made of several pieces of wood, which are called fellies." So Forester took Marco to the wheel, and showed him the parts of which the rim was composed.

While Marco was looking at the wheel, the blacksmith began to push away the burning brands a little from the tire, as it began to be hot enough.
