Report of the Commissioner of Patents for the year ..
This is an 1849 annual report of the United States Patent Office, printed in Washington for the House of Representatives, listing patents and agricultural matters. The single plate is rotated sideways on the page and shows a pen-and-ink drawing of two large cylindrical wooden or woven vessels, one tall and one lower, with a striped domed object between them and a figure at the right. A designer might take its hatched, shaded line work and its heavy, cylindrical forms as a model for mechanical or agricultural device illustration.
