Young scientist
A late nineteenth-century American science primer, published in New York in 1878 by the Industrial Publication Company for young readers, with the Smithsonian Libraries holding this copy. Its pictures are hatched line engravings of mechanical and technical objects, including a cross-section of layered strata with a nail and screw, a pair of split-block clamping diagrams, a tapered pin with a handle, and a row of ornamented cups, showing a designer clean diagrammatic linework with heavy cross-hatching and simple labels.
