on the weight in drams (avoirdupois) of a skein containing 1000 yards. A
skein, thus weighing 5 drams, is technically called 5-dram silk. The number
of yards of 1-dram silk to a pound must accordingly be 256000. The formulas
for figuring the amount of silk required for a piece of cloth are as
follows:

Warp Calculation

_Multiply_: Number of ends×length×count
-----------------------------
_Divide by_: 1000 yards×256 drams

[Page 72]
Filling Calculation

_Multiply:_ Picks×xply×width×length of piece×count
-------------------------------------- = lbs.
_Divide by:_ 1000 yards×256 drams

The result in both cases will be in pounds.

The system of grading the silk which is in vogue in Europe, and which is
employed by a number of mills on this side, is as follows:

1 skein of 500 meters, weighing 0,05 grams = 1 denier international
or 1 " 476 " " 0,053 " = 1 " Turin system
or 1 " 476 " " 0,051 " = 1 " Milan "

The warp calculation, taking the international denier, would run:
