Viewer

The manager of a colliery in the North East coalfield — the man who decided how the mine was to be worked and ventilated, and to whom the overmen answered. In the largest collieries he had an under-viewer beneath him.

Historical usage

The word belongs to Northumberland and Durham and to the period before "manager" became the statutory title. Greenwell’s glossary of the coal trade of the two counties gives two definitions a generation apart. In 1825 the viewer is "the person who gives directions as to the method of working and ventilating the mine. In large collieries he has a person under him called the Under-Viewer. From the viewers, overmen receive their instructions." By 1849 the definition has hardened into "The manager of a colliery; one who has the charge of all underground, and generally of all surface, arrangements." The role outlived the word: by the twentieth century glossaries describe viewer as "an early term for the general manager or mining engineer of one or more collieries", and it survives mostly in older records and in the names of the men who held it.

How it worked

A viewer was not tied to one pit. The best of them were consulting mining engineers who reported to a colliery’s owners on several collieries at once, laid out the workings, specified the ventilation, valued the coal and advised on leases. The under-viewer was "the responsible manager of a colliery in the absence of the viewer", and a check viewer was something else again — "a viewer employed by the lessor to see that the provisions of the lease are duly observed", watching the lessee on the landlord’s behalf.

Why it was used

The North East coalfield industrialised earlier and on a larger scale than anywhere else in Britain, and it produced a profession to match before the law required one. A viewer combined roles later split between colliery manager, mining engineer and consultant, and the great names of the trade were viewers: William Hedley, viewer at Wylam, built Puffing Billy and Wylam Dilly there.

Regional variation

Essentially a Northumberland and Durham word. It has no place in Barrowman’s glossary of Scotch mining terms, where the equivalent authority is simply the manager, with an oversman below him. Elsewhere in England the usual words were agent or manager.
