When the iintels { or girders are supported at the ends by brick walls or piers they shall rest upon cut granite

 thick, or upon cast-iron plates of equal strength by the full size of the bearings. In
 case the opening is less than twelve feet, the
 stone blocks may be six inches in thickness, or cast-iron plates of equal strength by the full size of the bearings may be used. This requirement shall not apply to the cast-iron

All lintes or girders placed over any opening in the front, rear or side of building, or returned over corner opening, when supported by brick or stone piers or iron columns, shall ! be of iron or steel and of the full breadth of the wall supported. In all buildings here-
 after erected of altered, where any iron or
 steel columns are used to support wall
 or part thereof, whether the same be an ex-
 terior or an interior wall, excepting . wall fronting on street, and columns located be- low the level of the sidewalk which are used to. support exterior walls. or arches over vaults, the said column or columns shall be

 be used as may be approved by the Inspector
 of Buildings Iron posts in front of party
 walls shall be. filled UT, solid with masonry
 and made perfectly tight between the post
 and walls to prevent effettually the passage
 of smoke or fire. Cast-iron posts or columns
 which are to be used for the support of wooden
 or iron girders or brick walls not cast with
 one open side or back. before being set up in place. shall have three-eighths of an inch
 hole drilled in the shaft of each post or eol- umn by the manufacturer or contractor fur-
 nishing the same, to exhibit the thickness
 of the castings; and any other similar sized hole or holes which the Inspector of Buildings or his duly authorized representatives may re-
 quire shall be drilled in the said posts or columns by the said manufacturer or con-
 tractor at his own expense. Iron posts or columns cast with one or more open sides and backs shall have solid iron plates on top of each to prevent the passage of smoke or fire through them from one story to an- other excepting where pierced for the pas- sage of ppes. No cast-iron post or column shall be used in any building of less average thickness of shaft than three-quarters of an inch nor shall it have an unsupported length
 of more than twenty times its least lateral
 dimensions or diameter. No wrought-iron or rolled steel column shall have an unsupported length of more than thirty times it's least J.% 1fy,,Ap nr 1 ia n ch ttc

 steel columns shall have their bearings faced
 smooth, and at right angles to the axis of the column; and when one column rests upon
 another column, they shall be securely bolted together. Where columns are used to support iron or steel girders carrying curtain walls. the said columns shall be of cast-ron, wrought-iron or rolled steel and on their exposed outer and inner surfaces be con- structed to resist fire by having 8 casing of brick work not less than four inches in thickness and bonded into the brick work of the curtain walls, or the inside surfaces of the said columns may be covered with an outer shell of iron having an air space be-
 tween; and the exposed sides of the iron or steel girder shall also be similarly covered in and tied and bonded. When the thickness of the curtain walls is twelve inches the girders for the support of same shall be placed at the floor line of each story, commencing at the line where the thickness of twelve inches starts from, and when the thickness of such walls is sixteen inches the girders shall be placed not farther apart than every other story at the floor line commencing ,t +h.
