The cruizey was all the lamp Thrums had in those days, though it is only to be seen in use now in a few old-world houses in the glens.

It is an ungainly thing in iron, the size of a man's palm, and shaped not unlike the palm when contracted, and deepened to hold a liquid.

Whale-oil, lying open in the mould, was used, and the wick was a rash with the green skin peeled off.

These rashes were sold by herd-boys at a halfpenny the bundle, but Cree gathered his own wicks.
The rashes skin readily when you know how to do it.

The iron mould was placed inside another of the same shape, but slightly larger, for in time the oil dripped through the iron, and the whole was then hung by a deck or hook close to the person using it.
