wooden girdels, supported by iron or WOod- ] eh coiuAhs, or piers of masonry, are SupStl | luleu lh place of brick partition walls, tho l building shall not exceed ten thousand ieeI | area on the ground floor, except ln case uL ire proQI buildings which may De construct | cd as herenuttcr provided for in section | thirty of this litle In ease the walls l of any building are less than twenty-five | feet apart and less than forty feet in depth, or there, are cross walls which lh. | terSeCL the wall, not more than forty Feet | distant or between the same, or piers or | buttresSeS built Into the walls, the interior walls may be reduced in thickness In just | proportion to the number Of cross walls, l piers or buttresscS, and their nearness to each other; provided, however, that this

 offs to the pottom and the Inspector of
 Buildings is hereby authorized and empoW- cred to decide (eNcept where herein other
 wise provided for) how much the walls | herein mentioned may be permitted to be reduced in thickness, according to the pccu- | liar circumstances of each case, without en- dangerlng the strength and safety of the | building. The walls of churches, theaterS, toundries, machine shops, car or stage houses, armories, public markets not over | two stories In height, and other buildings of l a pu c character, shall in no case be less 1 than Is in this act specified for warehouses; and said buildings shall have, in addition | thereto, such piers or buttresses as, In the IuNSluClit ol tue llSilGClOr Ol lully be necessary to make q safe and substantial | building. 0ne-story structures, not exceed
 ing, height of fifteen feet, may be built | with eight-nch walls when the bearing
 walls are not more than nineteen feet apart, and the length of the elght-inch bearing wall does not exceed forty-fve feet. Curtain walls of brick, built in between iron or steel
 columns, and supported wholly or in part on iron or steel girders, shall not be less than twelve inches thick for fifty feet of the up- permost height thereof, or to the nearest
 tier of beams to that measurement, in any building so constructed, and every lower | section of fifty feet, or to the nearest tier | of beams to such vertical measurement, or part thereof shall have q thickness of four | inches more than is required for the section | next above it, down to the tier of beams nearest to the curb level; and thence down 1 ward the thickness of walls shall Increase
 In the ratio prescribed in section twenty one of this title for the thickness Of found- l alton walls.
 1 The height Of all stories for all given | thicknessea of walls both in this section and section twenty three must not exceed eleven feet in the clear for the basement, | seventeen feet in the clear for the first story, fourteen feet in the clear for the sec ond story, and twelve feet in the clear in all stories above the second. If any story exceed these heights respectively the walls | of such story and the walls of all stories | below the same shall be increased four 1 inches i'll thickness additional to the thick uesses already mentioned.
 | Sec. 25. In all walls the same amount of
 materials may be used in piers or buttresseS. | Curtain walls may be made four inches less | in thickness than is specified respectively | for walls of dwellings, and buildings other | than dwellings, If any horizontal section
 through any part of any bearing wall q in | my building shows more than twenty live per centum area of fues and openings, the said wall shall be increased four inches in thickness for every ten per centum, or frac- | tion thereof, or Hue or opening area Ill eX- cess of twenty-five per ceutum. All piers shall be built of stone or good, hard we'll | burnt brick laid in cement mortar. Every l pier built Of brick, containing less than nine superficial feet at the base, supporting any beam, girder, arch or column on which | n wall rests, or Intel spanning an opening over ten feet and supporting q wall, snail
 at intervals of not over thirty inches apart In height have built into 1t Il bond stone not less than four inches thick, or q castiron plate of sufficient strength, and the full size of the piers. Isolated brick piers shall not
 exceed in height eight times their least di-
 mensions. Stone piers or posts for the sup port of posts or columns above shnll not De
 used in the interior of any building. Where walls or piers are built of coursed stone, with dressed level beds and vertical joints, the Inspector of Buildings shall have the
 right to allow such walls or piers to be built of a less thickness than specified for
 or piers be less than three-quarters of the thickness provided for brick work, In all brick walls every sixth course shall be Il heading course, except where walls are
 
 latter case every sixth course shall be bond
 ed into the backing by cutting the course of the face brick and putting In diagonal head
 CTS behind the same, or by splitting the face brick in half and backing the same with a continuous row of headers. All stone used for the facing of any building and known
 as ashlar, shall not be less than four inches thick Stone ashlar shall be anchored to the backing and the backing shall be of such thickness as to make the walls Gnde- pendent of the ashlar} conform to the thick ness required by sections twenty three and twenty four of this title. Iron ashlur plates used In imitation of stone ashlar on the face
 of q wall shall be backed up with the same
 thickness of brick work as stone ashar Walls heretofore built for or used as party walls. whose thickness at the time of their erection was in accordance with the require
 ments of the then existing laws, but which
 are not in accordance with the requirements of this title, may be used If in good condi tOn for the ordinary uses of party walls, provided the height of the same be not in
 creased In case 1t is desired to increase the height of existing party or Independent walls. which walls are less in thickness than required under this title the same shall be done by q lining of brick work to form a combined thickness with the old wall of not less than four inches more than the thick ness required for Il new wall corresponding with the total height of the wall when so Increased In height. The said lining shall be supported on proper foundations and
 carried up to such a height as the Inspector of Buildings may require. No lining shall be less than eight inches in thickness. and all lining shall be laid up In cement mortar and thoroughly anchored to the old brick walls with suitable wrought iron anchors, placed two feet apart and properly fastened or driven to the old walls in rows alternat- ing vertically and horizontally with each other, the old walls being first cleaned of plaster or other coatings where any lining is to be built against the same. In no case shall any wall or walls of any building bo carried up more than two stories in advance of any other wall, except by permission of 1 the Inspector of Buildings.

The or alteration thereof, shall be strongly brac cd rom the beams of each story, and, when required. shall also he braced from the out side. until the building is inclosed The roof tier of wooden beams shall be safely anchored with plank or ioist to the beams of the story below until the building is iE closed.
 Sec. 26 The walls of all buildings below the curb level, or the first tier of floor beams nearest thereto, shall be laid in cement nor tar and the buckingup of all stone ashlar shall also be laid up with cement mortar or cement mortar and lime mortar mixed but this shall not prohibit the pargnp of the back of the aShlar with lime mortar All other walls built Of brick or stone shall be laid in lime or cement mortar, or in lime and cement mortar mixed.
