Installment No. IX of the series "Weaving" in Engineering (Sept. 18, 1874), on shedding: how a weaver ties up headles (heddles) to treadles on a hand loom for twills and satins. It explains the draught and tie-up plan, treadling order, and the long and short marches (countermarch) arrangement. It also classifies six types of shed (through, rising, rising and falling, double), describes ways of holding down headles with weights or springs, and ends with the "Jack-in-the-box" shedding motion invented by Theodore Jennings around 1840.
