IEON FIELD ROLLERS. 
Plate XI. 
These are shown in plate, and are made of cast-iron, in cylindrical sections of one foot in 
lengtli, and as many sections as desired are fitted upon a shaft of the required length. 
§ 104. The Field Rollers are usually 30, 24 and 20 inches diameter, and generally of five to 
seven sections, having a wood plank box or tray above, which may be loaded with stones to 
increase the weight when more is required ; a strong tongue is also attached for drawing it. 
Each section revolves independently of the others, which greatly facilitates turning about 
with the roller, and avoids the shoving or tearing up the ground when turned. 
§ 105. The use of a Roller is too little understood by farmers generally. It levels and 
smooths plowed land, and when seeded to grass, it forces sods and small stones into the 
ground and pulverizes the lumps of earth, compresses the light soil at the surface around 
the seeds sown, thereby erasing a quick germination and growth. It prepares the ground by 
making a smooth surface for the scythe, mowing machine or horse rake. 
By thus compressing the surface, many kinds of injurious insects are deprived of shelter, 
which otherwise would find habitations among the lumps, stones and loose earth, to the 
greater injury of the growing crops. 
By rolling land in the spring after the frost is out, the earth is pressed hack around the 
roots from which it has been raised by the action of freezing, and often preserving the entire 
crop, while from the openness and exposure it would have been destroyed. 
For light lands which are too porous to retain a proper degree of moisture to protect 
vegetation from the scorching effects of a burning sun, the Roller is indispensable, often 
saving the entire crop, and always greatly increasing it. 
Although this compressed surface in all soils extends to a very slight depth, it is a sure 
preventive of the beating down of the earth by heavy rains ; as the crust, for such it really 
is, will withstand the force of the heaviest rain and hail storm, allowing the water to filter 
gently through it, without drowning and solidifying the earth beneath, as without the Roller.

HORIZONTAL SUG-AR CANE MILL, 
FOR POWER. 
Plate X. 
§ 107. The introduction of the Sugar Cane Plant in the Northern States, for the double 
purpose of food for stock and producing molasses, is of the most recent date. 
Although the experiment is as yet but partially made, the results thus far, where they 
have been conducted upon any system or with any reliable data, are very flattering. The 
importance of the plant, if for stock alone, makes it a valuable acqiiisition. 
With the knowledge already gained from the experiments made, it is not saying too much 
when it is stated, that less cost for outlay for the requisite apparatus to carry on this branch 
of business is required, than for machines for sowing, reaping and threshing *a crop of wheat, 
and the farmer can make a large production of molasses of the purest quality for the market. 
The Mill for expressing the juice is the most important of all the apparatus, and upon it 
depend the very success and profit of the undertaking. The considerations most necessary 
in a mill are its ability to press the juice clean from the cane, and the capacity to perform. 
The process necessarily consumes a constant and vast amount of power, and without 
strong machinery, and stronger power to drive it, little can be done. As Emery's Horse 
Power is susceptible of producing any desired degree of force for different purposes, the 
Proprietors have constructed a mill adapted to the business, which can be driven by a band 
from the Two-horse Power, and operate with the maximum force of the horses. 
The Mill is illustrated as in operation, in Plate X. It is constructed with three horizontal 
rollers, all strongly geared together, and driven by a powerful pinion and band wheel. The 
rollers are made adjustable to any amount of pressure required. 
The Mill is complete in itself. When used, it is mounted upon a substantial wood frame, 
with a wooden feeding hopper. The juice being received in the basin below the rollers, is 
conducted to the outside by a spout for the purpose. 
$ 108. The Mill, as mounted, will, with the Two-horse Power, press from sixty to one hun- 
dred gallons per hour, varying according to the maturity and yield of the cane and the 
closeness of the rollers, and consequently dryness of the pressed cane or bagasse. 
A treatise on the subject of its cultivation, manufacture, &c, will be furnished on appli- 
cation, post paid, for twenty-five cents ; the work contains the latest and most reliable 
information appertaining to the subject, up to and including last harvest. 
Price of the Mill, mounted on wood frame, $120; weight, about 500 lbs. 
Price of the Mill, not mounted, 100; weight, about 3U0 lbs.
