His three brothers then engaged in trade, and made considerable pecuniary acquisitions in it.

He himself might have partaken both of their concerns and of their prosperity; but he did not feel himself at liberty to embark in their undertakings.

He considered the accumulation of wealth as of no importance, when compared with the enjoyment of doing good; and he chose the humble situation of a schoolmaster, as according best with this notion, believing, that by endeavouring to train up youth in knowledge and virtue, he should become more extensively useful than in any other way to his fellow-creatures.
