A short 1849 Scientific American item on John Pepper of Portsmouth, New Hampshire, and his improved power knitting looms (machines), as seen in operation at H. and J. Crane's establishment. It compares weekly output of English hand stocking looms with Pepper's earlier rotary looms and his newest plain and ribbed looms. It also notes that the new looms can handle stronger yarns and run in independent sections of any width. A small woodcut of a knitting machine accompanies the text.
