England's treasure by foreign trade

"THE love and service of our Country consisteth not so much in the knowledge of those duties which are to be performed by others, as in the skilful practice of that which is done by our selves; and therefore (my Son) it is now fit that I say something of the Merchant, which I hope in due time shall be thy Vocation: Yet herein are my thoughts free from all Ambition, although I rank thee in a place of so high estimation; for the Merchant is worthily called The Steward of the Kingdoms Stock, by way of Commerce with other Nations; a work of no less Reputation than Trust, which ought to be performed with great skill and conscience, that so the private gain may ever accompany the publique good."
