First edition of an illustrated report on water management, published by three leading technical officers on behalf of the water board of Rijnland, here complete with all four appendices, sometimes lacking. In their report, Frederik Willem Conrad (1769-1805), Arie Blanken Jansz. (1766-1824) and Simon Kros (1746-1813) evaluate the several possibilities of connecting the river Oude Rijn with the North Sea. In 1803 a research commission chaired by Conrad came up with the present report, providing a definite scheme and an acceptable calculation of the costs. The water board accepted the proposals later that year and preparations for realizing the drainage canal commenced. In 1807 the outlet was completed, providing Rijnland with an excellent facility that proved its great benefits in the long term. The report includes several printed appendices and 18 engraved maps, profiles and technical drawings. Besides 2 overview maps, they include engravings showing several tracks of the proposed channel, detailed cross-sections, and profiles of soil test bores and the instruments used.
The edges and corners of the boards are slightly scuffed. The leaves are only slightly browned, the margins of a few plates are slightly soiled, otherwise in very good condition. Bierens de Haan 945; Kemper 1603; Saakes IV (1804), pp. 19, 50.
