Preface states the booklet is to remedy the problem that - "young boys...who were good calculators, did not know how to calculate a warp, simply because they did not understand it". Contains the calculation methods for weaving including references to warps, porties, healds, reeds and skeins. E.g. " Bring your woollen yards for one lb. Then divide by one skein for a dram, and the quotient will be the number of skeins thickness". First printed in 1871 but this is the Second Edition with no date. Printed in Huddersfield by J. Broadbent.
