New York: Printed for the Author by Alexander Niven, 1811. Hardcover. First Edition. 5.5 x 9in. [3] 288 [2]pp. + 18 copper engraved plates. Re-backed cloth over paper-covered boards of the period. FAIR. The boards show loss from along the edges and are well rubbed; scattered light foxing throughout, but heavier on the plates; rough-cut edges with some marginal loss from some margins; a plate with a large chip from the margin, but unobtrusive of image; some large chips of the back blanks; several amateur unfinished architectural sketches on the front blanks in a hand of the period. Otherwise the binding is strong and tight and the text and plates remain unmarked and complete. As pictured.

Tall 8vo, original leather backed boards, illustrated with 18 copper-engraved plates, [18], [ix]-xxxii, [33],-288 pp. Covers rubbed, corners worn, bottom corner of top cover broken off, top hinge weak, spine scuffed; darkening and foxing to contents, occasional dampstains, in rare untrimmed state in the original boards, partially unopened. Plates do not appear to be in correct order, and a couple are not numbered, but all seem to be present. This is a rare American work on bridge building, which presents Pope’s plan to build a "flying pendent lever bridge" over the Hudson River. This is only the second American book on the subject, following Peale’s work, "An Essay on Building Wooden Bridges" (1797). Pope includes a discussion of the history of bridges in different parts of the world, and follows with a description of his flying pendent bridge. While Pope’s bridge design may have been unappreciated at the time, it became the basis for the cantilever bridge.
