wayzgoose: an entertainment given by a master printer to his workmen, marking the beginning of work by candle-light, usually about Bartholomew-tide. The derivation of this term is not generally known. It is from the old English word wayz, stubble. A stubble goose is a known dainty in our days. A wayz-goose was the head dish at the annual feast of the forefathers of our fraternity.
