They went up the bank and thence into the mill.
The man who owned the boat, was tending the mill.

When he wanted a log, he would take the end of a long chain down a sloping plane of planks which led to the water, and fasten it to a log.

The other end of the chain was fastened round an axle in the mill, and when all was ready, the man would set the axle in motion by the machinery, and that would draw the log up.

When the log was in the mill, the man would roll it over into its place, on a long platform of timber, where it was to be sawed.

Then he would set the saw machinery in motion, and the platform would begin to move forward, and the saw at the same time to go up and down, sawing the log as it advanced.
