s per inch to be drawn on 4
shafts, we must give each shaft 25 heddles per inch. There are generally
between 25 and 45 heddles per inch on one shaft.
8. REDUCTION OF THE FILLING
Here we state the number of picks per inch, give directions as to doubling,
if such is necessary, and if more than one color or shuttle is used, the
rotation thereof.
9. CALCULATION OF WARP AND FILLING
The system adopted in this country for specifying the size of silk is based
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 endsxlengthxcount
-----------------------------
_Divide by_: 1000 yardsx256 drams
[Page 72]
Filling Calculation
_Multiply:_ Picksxxplyxwidthxlength of piecexcount
-------------------------------------- = lbs.
_Divide by:_ 1000 yardsx256 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:
ends in warpxlengthxdenierx0,05 gram
--------------------------------------
_divided by:_ 500 meters
for the filling: Picks per meterxxplyxwidthxdenierx0,05 gram
---------------------------------------------
_divided by:_ 500 meters

Sir Thomas Henry Hall Caine CH, KBE (May 14, 1853August 31, 1931), usually known as Hall Caine, was a British author. He is best known as a novelist and playwright of the late Victorian and the Edwardian eras.

From that point on, MacGrath never looked back, writing novels for the mass market about love, adventure, mystery, spies, and the like at an average rate of more than one a year. He would have three more of his books that were among the top ten bestselling books of the year. At the same time, he penned a number of short stories for major American magazines such as The Saturday Evening Post, Ladies Home Journal, and Red Book magazine. Several of MacGraths novels were seriali
