A short dictionary entry on the yarn-tester, an instrument for measuring the breaking strength of yarn. It explains how a skein of yarn is passed over two hooks and strained with a hand-wheel and screw until it breaks, while a weight rising along an arc and a dial index show the breaking load. Two engravings show a yarn-testing reel and the yarn-tester.
