The attention of Architects, Engineers, and Builders is called to the
great decline in prices of wrought STRUCTURAL IRON. It is believed that,
were owners fully aware of the small difference in cost which now exists
between iron and wood, the former, in many cases, would be adopted,
thereby saving _insurance_ and avoiding all risk of _interruption_ to
_business_ in consequence of fire. Book of detailed information
furnished to Architects, Engineers, and Builders, on application.
