Afhandling om Strömsholms Canal och Slusswärk.

4to. (6), 36, (4) pp. With a folding table and a folding engraved map in hand colour, 147 cms in length. Modern marbled boards. First monograph about the just-completed Strömsholm Canal connecting Grangärde (in Dalarna, middle Sweden) with Strömsholm on Lake Mälaren, from where ships have easy access to Stockholm. Work on the 62-mile canal, intended to facilitate transport for the numerous steel works along the waterway, had begun in 1772: based on plans by Johan Ullström, a series of lakes were connected by short canals and a total of 25 locks. The fine map, nearly one and a half metres long, shows the entire stretch of the structure. Earlier the same year, the author Magnus Schenström (1775-1848) had published an eight-page Latin dissertation "De canalibus et catarractis in Svecia generatim, speciatim vero Strömsholmensibus", which he subsequently expanded into the present account of the canal. - Some slight marginal waterstaining, but a good, wide-margined copy.
