subs. phr. (thieves).1. A thief who steals lead from the roofs of buildings. [HOTTEN:Sometimes a journeyman plumber, glazier, or other workman, who, when repairing houses, strips off the lead, and makes away with it. This performance is, though, by no means confined to workmen. An empty house is often entered and the whole of the roof in its vicinity stripped, the only notice given to the folks below being received by them on the occasion of a heavy downfall of rain. The term FLYER has, indeed, of late years been more peculiarly applied to the man who steals the lead in pursuance of his vocation as a thief, than to him who takes it because it comes in the way of his work].
2. Fr. limousineur; gras-doublier; mastaroufleur. Hence TO FLY THE BLUE PIGEON = to steal lead from the roofs of houses. Fr. faire la mastar au gras-double; ratisser du gras double.
