Two pages from The Textile Mercury of 10 January 1891. The main piece describes the conversion of India Mill, Darwen, from wheel gearing to rope driving, covering the engines by Musgrave and Sons and the Lambeth cotton driving rope made by Thomas Hart of Blackburn, with its construction and breaking-strain tests. The second page begins a 'Bleaching, Dyeing, Printing, etc.' section with a piece on alizarine dyes on wool and weathering tests, and the start of a piece on printing insoluble azo-colours on cotton.
