When a farmer has been at the expense and trouble of raising a crop
of sugar-cane, he wants to get the most out of it he possibly can, and to
that end he must have the best appliances he can get for the purpose.
The Cane Mill
The first consideration is the mill. It should be of the most approved
style, and capable of getting at least 75 per cent. of the juice from the cane.
There are several excellent makes on the market, from a light one-horse
mill up. The size should be decided by the amount of cane to grind, but
it never pays to get a small mill. The three-roller vertical type gives the
The location of the mill should be arranged high enough aboye the
position of the evaporator to enable the juice to be run by gravity in a
pipe from the straining tub to the evaporator. This saves time, and gives
a constant supply of juice ready for the evaporator.
The Foundation of the Mill
The mill must be set on a solid foundation, and this foundation brace-l
in such a way that it will be impossible for the mill to move from position
while at work. The best foundation, under ordinary conditions in this State,
consists of lightwood posts, not less than fourteen inches in diameter and
ten feet long, set in the ground at least five feet deep. The proper setting
of these posts is quite important. Holes must be dug for every individual
post with a slant towards the center, so that when the mill is set on top
of them it will be on a level. Therefore all the holes must be dug to the
same depth, with a post-hole digger if possible. We want as small a
hole as will take the post, for the smaller the hole the better able we will
be to make a solid job of the necessary tamping after the post is in place.
In setting these posts so as to get them perfectly solid, sand or soil must
be tamped all around each individual post, and plenty of water poured on
during the tamping process to help make them solid in their places, so that
none of them will move when grinding begins. Then brace them thoroughly
from the inside with 2 by 4 scantling material.

Setting the Mill in Position
In setting the mill in position on top of these posts, a good plan is to
bolt a couple of pieces of 2 by 6 inch, about 3 feet long, to the base of the
mill, and then bolt these pieces to the top of the posts, either by lag
screws or set-in bolts. This makes it easier to level up the mill, and helps
the solidity of the whole.
If the posts are ten feet long, and are set five feet in the ground, a
space of five feet is available for the juice tub and the necessary straining
Straining the Juice
The first step towards getting a high-grade syrup is the clean and
thorough straining of the juice as it leaves the mill spout. A tub made
from the half of a syrup barrel answers well for the strainer. A hole should
be bored in the side of the tub large enough to admit the end of the juice
pipe, and the junction should be made tight so as not to leak. The tub
should be placed on a platform to get it up close to the mill spout. A
piece 6\ fine wire-cloth should be tacked over the hole at the end of the
pipe in the tub, to act as a strainer. This should be fitted on so that it
can easily be taken off for cleaning, which will often be necessary. If "black
moss" can be had in quantity, an excellent juice filter can be made by
filling the tub with it; but it must be renewed several times daily. It can
be used over again if it is washed and dried, and then the dust shaken
from it. On top of the tub and held in place by a wire hoop, a double
thickness of cheese cloth should be used. This will also require to be
often renewed. On top of all a piece, about 18 inches square, of ordinary
window wire netting should be laid, to catch the rougher parts as the
juice runs from the mill spout.
This gives us three strainings and a filtering, which should make the
juice clean enough for evaporating.
