Short Cross

See Chase. — M.

The shortest and also the broadest bar that divides a chase into quarters; there is a groove in the upper side of it to admit the spurs of the points to be pressed into it without injuring their points. This cross is dovetailed in the middle of the sides of the chase, for folios, quartos, and octavos, without the long cross for folios; there is another dovetail in the rim of the chase, leaving about two thirds of the chase on one side of the short cross and one third on the other; the cross is fitted into these dovetails for twelves, and separates the offcut from the other part of the sheet. I would always place the short cross in the middle of the chase for eighteens, where the margin will admit it, as it divides the pages more equally, and makes the form safer when locked up; in this case the cross occupies the place of a gutter instead of a back.
