Dowpot Syke and Guttergill Mine

Overview

Dowpot Syke and Guttergill are two adjacent lead workings on Alston Moor, near Garrigill, listed together as a single mine in the 1888 List of Mines — and, confusingly, entered twice in that list with the two names in either order. Both were already named lead groves two centuries earlier: they appear in surveys of the Derwentwater estate mines drawn up for the Greenwich Hospital commissioners in 1735 and again in 1737, among a long list of Alston Moor workings that included Guttergill, Dowpott Syke head and the moss on its eastern side.

History

Alston Moor's lead grounds passed to the Greenwich Hospital after the Derwentwater estates were forfeited following the 1715 rising, and the surveys the Hospital's officers drew up in the 1730s are the earliest documentary appearance of these two workings. John Watson's memorial to Thomas Corbett of 18 July 1735 lists Guttergill and Dowpott Syke head — and, separately, the moss on the east side of Dowpott Syke head — among the groves of the estate. Nicholas Walton's letter to William Corbett of 14 October 1737 lists both again. Watson's memorial is also a window on how the ground was held and worked: proprietors either worked the mines themselves or granted tack notes and leases to adventurers who paid no fixed rent but a fifth, sixth or seventh dish of all well-washed ore, the Derwentwater family having generally used the latter method at a fifth. A lessee who failed to work with four men a day for twenty days in a year — Sundays, holy days and violent storms excepted — forfeited the lease and paid twenty shillings a month for the discontinuance. Watson proposed tightening this to eight pickmen with monthly written returns of every miner employed, and a forfeiture of the lease plus £9 for every week of hushing without written licence, on the grounds that though hushing was an easy way to get ore it did damage to all mines and veins for later adventurers. By 1888 the two names were still being worked as one concern.

Geology

The workings lie in the Alston Block, the central portion of the Northern Pennine Orefield, where lead ores occur in mineral veins occupying faults through the Carboniferous sequence. No description of the specific veins at Dowpot Syke or Guttergill has been located. The names themselves are those of the becks and gills the workings follow, which is the usual pattern on Alston Moor, where a vein was commonly named for the water that first exposed it.

Workings

No description of the workings has been located. The 1735 memorial's concern with hushing on the estate — and its proposal to fine lessees £9 a week for hushing without licence, because of the damage it did to the sills of a vein for later working — indicates that surface hushing was in common use on these grounds at the time, whether or not it was practised at these two particular groves.

Closure

No closure date has been located. The pairing was still listed as a working mine in 1888.

What remains

No account of the present state of the workings has been located.

Recorded claims

Individual factual claims, each attached to the source(s) that support it below. Where sources disagree, both are kept.

• Guttergill and Dowpott Syke head are both named among the lead groves of the Derwentwater estate on Alston Moor in John Watson's memorial to Thomas Corbett of 18 July 1735, which also separately lists the moss on the east side of Dowpott Syke head. ¹
• Both Dowpot Syke and Guttergill appear again in Nicholas Walton's letter to William Corbett of 14 October 1737. ²
• Adventurers on the Derwentwater grounds paid no fixed rent but a fifth, sixth or seventh dish of all well-washed ore, the family generally taking a fifth; a lessee who failed to work with four men a day for twenty days in a year, Sundays, holy days and violent storms excepted, forfeited the lease and paid twenty shillings a month for the discontinuance. ¹
• Watson proposed a forfeiture of the lease and £9 for every week a lessee hushed a mine without written licence, on the grounds that though hushing was an easy way to get ore it damaged all mines and veins for later adventurers unless the sills were left entire. ¹
