I beg the reader to remark, that the power which exists in the tool to increase the productiveness of labor, is the basis of the solution which follows.
At the end of ten days, James had in his possession an admirable plane, which he valued all the more for having made it himself.

He danced for joy--for, like the girl with her basket of eggs, he reckoned all the profits which he expected to derive from the ingenious instrument; but more fortunate than she, he was not reduced to the necessity of saying good-bye to calf, cow, pig, and eggs, together.

He was building his fine castles in the air, when he was interrupted by his acquaintance William, a joiner in the neighboring village.

William having admired the plane, was struck with the advantages which might be gained from it.

He said to James: _W._ You must do me a service.
_J._ What service?
_W._ Lend me the plane for a year.
As might be expected, James at this proposal did not fail to cry out, "How can you think of such a thing, William?
Well, if I do you this service, what will you do for me in return ?" _W._ Nothing.
