First of all, Kiliaen van Rensselaer's patroonship of Rensselaerswijck wasn't even acquired until 1631. It wasn't until the early 1650s that a Van Rensselaer (Jan Baptist) set foot in the New World. Also, brickmaking didn't come until the 1650s; the "yellow bricks" so often mentioned came from ships' ballast probably bought from the brickyards near Wijk bij Duurstede in the Netherlands. I suggest that Fitch's source for this statement be checked. Charles Gehring New Netherland Project >>> [log in to unmask] 02/07/03 15:30 PM >>> To Historians All! In "American Building: The Historical Forces That Shaped It" by James Marston Fitch a line on page 13, reads as follows: "In 1628 the canny Rensselaers were producing the favorite Dutch yellow brick on their estates near Albany, N.Y., and selling them to all comers for fifteen florins a thousand." My question : How can "fifteen florins" be converted to a 2003 monetary value? Leo Dodd Historic Brighton
