run elevators and conveyors, and especially in elevating and conveying
middlings, especially those made from winter wheat, their quality is
inured and a loss incurred, by the unavoidable amount of flour made by
the friction of the particles against each other. So much is this the
case that in one of our largest mills it is deemed preferable to move
the middlings from one end of the mill to the other by means of a hopper
bin on a car which runs on a track spiked to the floor, rather than to
employ a conveyor. A mill built as I am going to describe would require
from fifty to sixty horse-power to run it, and including steam power and
building would cost from $10,000 to $12,000, according to location. I
give it as of interest to those among your number who own small mills
and may contemplate improving them.

The building is four stories high, including basement, and thirty-two
feet square. It would be some better to have it larger, but it is made
this small to show how small a space a mill of this size can be made to
occupy. No story is less than twelve feet high. The machinery Is very
conveniently arranged, and there is plenty of room all around. The
system is a modification of the gradual reduction system, the middlings
being worked upon millstones. The first break is on one pair of 9 x
18 inch corrugated iron rolls, eight corrugations to the inch, the
corrugations running parallel with the axis of the rolls. The second
break on rolls having twelve corrugations to the inch, the third
sixteen, and the fourth twenty to the inch, while the fifth break, where
the bran is finally cleaned, has twenty-four corrugations to the inch.
The basement contains the line shaft and pulleys for driving rolls,
stones, cockle machine, and separator. The only other machinery in the
basement is the cockle machine. The line shaft runs directly through
the center of the basement, the power being from engine or water wheel
outside the building. The first floor has the roller mills in a line
