Edinburgh, printed by W. Burness 1851. Quarto publisher's printed green wrapper (frayed); 25pp, largish folding tinted lithograph; wood engravings through the text. An attractive copy. ¶ An appealing and rare trade puff. The frontispiece is a captivating tinted lithograph view of a Dredge bridge in an idyllic setting, with leisurely boaters and fishers on unruffled waters as the sun sets behind a hill, and though a heavily laden old woman trudges across the bridge she seems as sturdy, unbowed and as calm as the bridge itself. The success of James Dredge's patented suspension bridge was due to the suspension chain tapering in toward the centre of the bridge and the suspension rods being set obliquely towards the centre rather than being vertical. It had to overcome 'unusual opposition and prejudice' but by 1851 several had been built - in England, Ireland, India and Jamaica - and a handul of these survive. By arrangement with Dredge and Stephenson, Young and Company would now manufacture the bridges and the engineers would design and supervise construction. Much of this pamphlet is devoted to reprinting various papers - a couple by Dredge - examining, explaining and praising the design.AUD 750.00 [Appr.: EURO 532.25 US$ 574.64 | £UK 459.5 | JP¥ 63908] Book number 7563
