Gun sleighs in Canada.
--It is stated that the Canadian troops have had a new addition to their armament of a curious character. Fearful that an attack might be made upon them during winter — at which time the snow lies deeply on the ground for many weeks, and that thereby their movable artillery might be rendered comparatively useless — contracts have been made for building gun sleighs. One of these contracts has recently been awarded to a carriage building firm in Montreal.
