To Find the Weight of a Given Yarn to be Twisted Witha Yarn, the Weight and Counts Being Known. The problemmay now be put in a different way. There may be a givenquantity of one of the yarns, and it is required to find whatweight will be necessary to twist with it and just use it is obviously the reverse of the above proceeding, and at onceresolves itself into a simple proportion, being dependent only uponthe relative counts; thus 20s and 30s are to eacirother as 2 is to3, and, as the higher number is the lighter yarn, the proportionmust be inverse. Supposing then, that there are 400 pounds of 30s yarn andit is required to find how m
