Scientific American, Vol. 77, No. 7 (August 1897)
An issue of the weekly Scientific American, published by Munn & Co. in New York in August 1897 for inventors, engineers and technically curious general readers. The illustrations are wood-engraved technical views, including a sectional elevation of a garbage reduction plant showing inclined conveyor, bolted tank digesters, timber framing and hatched ground line — useful for machinery outlines, cutaway conventions and fine parallel-line shading.
