10 July 1656 – 16 July 1656

I returned homeward, passing again through Colchester; and, by the way, near the ancient town of Chelmsford, saw New Hall, built in a park by Henry VII. and VIII., and given by Queen Elizabeth to the Earl of Sussex, who sold it to the late great Duke of Buckingham, and since seized on by Oliver Cromwell (pretended Protector). It is a fair old house, built with brick, low, being only of two stories, as the manner then was; the gate-house better; the court, large and pretty; the staircase, of extraordinary wideness, with a piece representing Sir Francis Drake's action in the year 1580, an excellent sea-piece; the galleries are trifling; the hall is noble; the garden a fair plot, and the whole seat well accommodated with water; but, above all, I admired the fair avenue planted with stately lime trees, in four rows, for near a mile in length. It has three descents, which is the only fault, and may be reformed. There is another fair walk of the same at the mall and wilderness, with a tennis-court, and pleasant terrace toward the park, which was well stored with deer and ponds.

Came home by Greenwich ferry, where I saw Sir J. Winter's project of charring sea-coal, to burn out the sulphur, and render it sweet. He did it by burning the coals in such earthen pots as the glass men melt their metal, so firing them without consuming them, using a bar of iron in each crucible, or pot, which bar has a hook at one end, that so the coals being melted in a furnace with other crude sea-coals under them, may be drawn out of the pots sticking to the iron, whence they are beaten off in great half-exhausted cinders, which being rekindled, make a clear, pleasant chamber-fire, deprived of their sulphur and arsenic malignity. What success it may have, time will discover.
