Der neue und merkwürdige Pflug, der keinen Führer braucht : erfunden von Jean Joseph Grangé, einem gemeinen Ackerknechte aus Harol, im Departement der Vogesen in Frankreich$naus dem Französischen übersetzt von Carl Ernest Mayer
An 1834 German translation, by Carl Ernest Mayer from a French original, published by Mörschner und Jasper, describing a self-guiding plough invented by Jean-Joseph Grangé, a farm labourer from Harol in the Vosges. The first picture is a red wax seal showing a standing robed figure with lettering around its edge, and the second is a set of numbered engraved plough diagrams in four figures, showing wheels, beams, and handles in side and plan views. For a designer, the engraved plates offer clear mechanical line drawings of a wheeled implement, useful as technical illustration references.
