[Owing to the difficulty of identifying lights on a coast,the least number that can be employed is the best; hut ifsome distinguishing mark can be fixed to a lighthouse, bywhich all possibility of mistake is prevented, some objec-tions to frequent lights would he removed.—S. C.]

any height within its range, supporting itself with safety!independently of any attachments.
The machine consists of a series of hollow rectangularframes, sliding one within another, after the manner ofthe tubes of a telescope; mounted upon wheels, andhoisted or lowered by ropes and pulleys, by means ofwinch handles, turning a barrel, round which are twistedthe lower ends of the ropes of the second frame. By ®repetition of this arrangement each frame is raised out ofthe frame below it, at an equal rate with all the others,but the absolute velocities of all the frames successivelyare in arithmetical progression.

The accompanying two diagrams are in illustration 0a new system of working railways, intended to dispen swith all break of gauge.
The plan suggested is to convert the narrow-gang „railways into broad-gauge lines, by laying down rails 0the seven-feet width on the outer sides of the presennarrow-gauge railways, so as to form them into four-ramixed-gauged lines, until the traffic be entirely transfe rf nfrom the narrow-gauge to the broad-gauge rails, wheninner or narrow-guage rails would be permanently rmoved. The new form of carriage here proposed, ashown in the diagrams, has three pairs of large whenplaced on the outer sides of the body.
