"We want the fellows to get the benefit.
We don't want all the profit.

As it is, we shall make a farthing on every tart we sell.

We ought to sell four times as many as Bob did, oughtn't we ?" "Quite that," said they.
"Very well; see how that works out." And Mr Stratton took his chalk and worked out this sum on the black- board:-- 12 bad tarts at 11/2 pence = 1 shilling, 6 pence, cost 9 pence, profit 9 pence.
48 good tarts at 1 penny = 4 shillings, cost 3 shillings, profit 1 shilling.
"You see," said he, "if we can only increase the demand, we shall easily make Bob's profit, and more.

Having good tarts will increase it in one way, and selling cheap will increase it another.

It's worth trying, anyhow." And so the deliberations went on, and the boys' minds gradually took on the new idea.
The thirty shillings, Mr Stratton reported, had been advanced, and Mrs Stratton was appointed a subcommittee to lay it out.
