If the crank shaft of a power loom makes 119.441 revo-lutions a minute .i.e so many picks or threads what length time must it work succes-sively to produce a piece of [cloth?] 29 yards long with 84 pick or threads in 1 inch

Or

When the Warp and filling are the same it may be worked in one operation by [multipleing?] the count of reed by the pricks in 1 inch and the length of the piece and the inches width at the reed for a dividend. Then multiply the number of hanks in 1 yard by the number of yarn for a divisior and the product will be the answer

The weight of yarn is required in the following manner

Rule

Multiply the length of the piece required by the count of the reed and the product by the wedth at the reed for a dividind for the warp dividind 840 yds 1 hank divisor

Then Multiply the length of the piece by the picks 1 inch then by the inches wide at the reed for a dividend for filling andivid by the number of yds in one hank then add the two products together and divide by the number of yarn and the decimals by the [or?] lb
