Not only did Penn obtain a grant of land possessed of rare and diversified natural beauty, extreme fertility, mineral wealth and richness of all kinds, but he showed great sagacity in encouraging ambitious men of education and affluence, and artisans of skill and taste in many lines, to colonize it. To these facts are due the quick prosperity which came to Philadelphia and which has made it to this day one of the foremost manufacturing centers in the United States. Textile, foundry and many other industries soon sprang up to supply the wants of these diligent people three thousand miles from the mother country and to provide a basis of trade with the rest of the world. Shipyards were established and a merchant marine built up which soon brought to Philadelphia a foreign and coastwise commerce second to none in the American colonies. Local merchants engaged in trade with Europe and the West Indies, and these profitable ventures soon brought great affluence and a high degree of culture. By the time of the Revolution Philadelphia had become the largest, richest, most extravagant and fashionable city of the American colonies. Society was gayer, more polished and distinguished than anywhere else this side of the Atlantic. Among the skilled artisans attracted by the promise of Penn's "Sylvania" were numerous carpenters and builders. Penn induced James Portius to come to the new world to design and execute his proprietary buildings, and Portius was accompanied and followed by others of more or less skill in the same and allied trades. While some of the building materials and parts of the finished woodwork were for a time brought from England, local skill and resources were soon equal to the demands, as much of their handiwork still existing amply shows. As early as 1724 the master carpenters of the city organized the Carpenters' Company, a guild patterned after the Worshipful Company of Carpenters of London, founded in 1477. Portius was one of the leading members, and on his death in 1736 laid the foundation of a valuable builders' library by giving his rare collection of early architectural books to the company.
