Colliery survey in progress 1878

Surveyor looking through the sighting arms of his miner's dial towards the assistant's lamp. The assistant has the end hand loop of a surveying chain (22 links equals one chain, remember?) in his hand.

Entitled "surveying under difficulties". Must be catching up with a survey in workings which have flooded in the meantime. Surveyors were usually called in once a month or even longer periods to update the survey rather than being employed full time.
