To quickly assess the difficulty of the text, read a short excerpt:
Tl^-* -' 60+TO = ^'' '^'" 30^^60 = '^- So that both the 40 skeins and 60 skeins twist would be reckoned as 20 skeins. If two yarns of different material are combined — as, for instance, a 2-fold 80's worsted with a 2-fold 60's silk — then they have both, in the first place, to be reduced to the same counts. A 2-fold 50*s worsted is equal to 25 hanks of 560 yards each in a pound, whereas a 2-fold 60* s silk is equal to 60 hanks of 840 yards each to the pound ; so that it is essential to find the... equivalent either of a 2-fold 60's silk in the worsted counts, or of a 2-fold 50's worsted in the silk counts. The silk will be brought to its equivalent in worsted hanks. In order to reduce any two counts to the same basis, bring one of them to yards, and divide by the standard length of the other. Example. — 2-fold 60*8 silk equals 60 hanks, or, in other words, a pound of such silk contains 840 x 60 = 50,400 yards. Now, if this number is divided by the yards in the worsted hank, 560, it will give the equivalent required^ thus : 50,400 h- 560 = 90's worsted.
