ring rice-starch on a large scale, Patna rice
yields 80 per cent, of marketable starch, and 8.2 per cent. of fibre,
the remaining 11.8 per cent. being made up of gluten, gruff, or bran,
and a small quantity of light starch carried off in suspension by the
solution.

Jones's process may be thus described:--100 lbs. of rice are macerated
for 24 hours in 50 gallons of the alkaline solution, and afterwards
washed with cold water, drained, and ground. To 100 gallons of the
alkaline solution are then to be added 100 lbs. of ground rice, and
the mixture stirred repeatedly during 24 hours, and then allowed to
stand for about 70 hours to settle or deposit. The alkaline solution
is to be drawn off, and to the deposit cold water is to be added, for
the double purpose of washing out the alkali and for drawing off the
starch from the other matters. The mixture is to be well stirred up
and then allowed to rest about an hour for the fibre to fall down. The
liquor holding the starch in suspension is to be drawn off and allowed
to stand for about 70 hours for the starch to deposit. The waste
liquor is now to be removed, and the starch stirred up, blued (if
thought necessary), drained, dried, and finished in the usual way.[44]
Rice is imported into this country in bags of 11/2 cwt., and tierces of
6 cwt., not only for edible purposes, but, when ground into flour, for
cotton manufactures, in aiding to form the weaver's dressings for
warps. Rice-meal is commonly used for feeding pigs.
