And be it enacted, That if any building or excavation on any land or place contiguous to any street within the limits of this Act shall for want of sufficient repair, protection, or inclosure, be dangerous to the passengers along such street, the owner thereof shall be liable to a penalty not more than five pounds. And be it enacted, That it shall be lawful for the vestry or district board during such time as any street within the limits of this Act is being made or repaired, or during the making of any sewer or drain by the vestry or district board, or when they shall consider it expedient to close such street, or any part of the same, by such ways or means as they shall think fit. Every vestry and district board shall have full power and authority to pave, if they think fit, any uninclosed space which may have been the forecourt of any house or building in any street, and the same shall thenceforward become the public highway, and whenever the fence or other enclosure shall have been removed, it shall not be lawful for the owner or occupier of the said house or building again to enclose the said space. * * * * * _From the Vestry Clerk to the Clerk of the Metropolitan Board of Works_.
