Scientific American, Vol. 87, No. 22 (1902)
This 1902 issue of Scientific American, volume 87, number 22, was a weekly New York magazine for a general readership of engineers, inventors and technically minded readers. Its pictures are black-and-white photographs with printed captions, showing a steam-powered boat in rough water, dredging and river-bank construction work, and a small mechanical bricklaying machine on a brick wall, useful to a designer wanting documentary views of early industrial machinery and labour.
