With the elevated of the street, they offer little or no obstraotion to gas and over-crowded system of tramportation, is a fact conceded by railway built, all of those encumbmacesmay be removed fnm water pipes or sewers. 2. Upon each iron croi^head, fitted to the top of columns and hdd seonrely in its place by substantial yet ornamental brackets, is* placed a cross-tie of wood with intervening pads of India rubber, to deaden the noise, and prevent crystallin- tion and wear of iron from the content vi¬ brations wbkb, through a too rigid at- ■> tachment of parts, would be communi¬ cated from the movement of the cars, pp ' By a simple form of rail-chair, combinad with straps, bolts and nuts, the entire cross- head and rails at each column are firmly A JouKSAL OF MrP>*»NG, all; but upon what plan can a reform be best obtained? The {tho streets, and by an easy combination of attachments, abet- j clamped, with the use of only four bolts and nuts, thus spectacle which New York presents, of a population packed ter support for each is supplied. The form of these columns, i rendering the insertion of new ties, new pads, or new into cars as sardines in a box; of hours lost, where minutes as seen in Figs. 6 and 7, combine great .strength with sim-I iron cross-heads an easy matter. 8.

They are formed with iron, with or without steel face, have a depth of twelve inches, choked by multitudes of vehicles, H moving often at snail’s pace, is dis- ■ graceful and insufferable. It is im- I possible that this state of things shall long continue. The need of increased facilities for dty travel is too great, and presses too sore upon all for longer delay on the subject. It is not a question of this or that company, but of the plan which will yield most speedy relief.

These columns are inches, and are distingnisbed for ligbtnese, with safficimit buildinp, with a car upon the track.
