When transferring combs into frames we temporarily secure them in
position by the aid of slips of wood a sixteenth of an inch thick by
half an inch wide, tacked on each side, and one or more zinc slips as
delineated in the engraving.
All these artificial supports should be removed as soon as possible.
The combs will generally be found firmly fixed in less than forty-eight
hours.
