s to have succeeded in obtaining the means of prosecuting
his original invention; for in his Metallum Martis, published in 1665,
he describes himself as living at Green's Lodge, in Staffordshire; and
he says that near it are four forges, Green's Forge, Swin Forge, Heath
Forge, and Cradley Forge, where he practises his "perfect invention."
These forges, he adds, "have barred all or most part of their iron with
pit-coal since the authors first invention In 1618, which hath
preserved much wood. In these four, besides many other forges, do the
like [sic ]; yet the author hath had no benefit thereby to this
present." From that time forward, Dud becomes lost to sight. He seems
eventually to have retired to St. Helen's in Worcestershire, where he
died in 1684, in the 85th year of his age. He was buried in the parish
church there, and a monument, now destroyed, was erected to his memory,
bearing the inscription partly set forth underneath.[17]

[1] As late as 1790, long after the monopoly of the foreign merchants
had been abolished, Pennant says, "The present Steelyard is the great
repository of imported iron, which furnishes our metropolis with that
necessary material. The quantity of bars that fills the yards and
warehouses of this quarter strikes with astonishment the most
indifferent beholder."--PENNANT, Account of London, 309.

[5] Mr. Parkshouse was one of the esquires to Sir Ferdinando Dudley
(the legitimate son of the Earl of Dudley) When he was made Knight of
the Bath. Sir Ferdinando's only daughter Frances married Humble Ward,
son and heir of William Ward, goldsmith and jeweller to Charles the
First's queen. Her husband having been created a baron by the title of
Baron Ward of Birmingham, and Frances becoming Baroness of Dudley in
her own right on the demise of her father, the baronies of Dudley and
Ward thus became united in their eldest son Edward in the year 1697.
