SCREW PRESS can be driren by Cattle, as the cotton accumu'ates from the 
Gin, both being under one roof. The screwing of the cotton into compact balee 
iaves heavy freight : say j or | (of a penny) per lb. instead of Id. or 1 ji. It is 
described in the " Tropical Agriculturist." 
CL.\SSING AND SEPARATION.— Besides clean and stained cotton, it will 
be found on observati n that the worst and heaTie-t falb immediately at the back 
of the Gin, containing sand, earth, and dust, while the lighter and better is 
thrown to some distance back : — the two should not be mixed, but packed and 
marked separately, — which the Ginner and packer if only hired is apt to collect 
all in one. When sold in Liverpool the manufacterers often obtain a deduction 
of 2 per cent, and upwards for sand and refuse. 
FANNER AND BRUSHES. — In the Saw- Gin the brus>^e§ sweep the wool 
off the saws, and the arms of the fanners blow it out of the frame, to a greater or 
less distance. The brushes being of hair get worn out, and when this is the case 
the cot-on is apt to be carried round a second or third time, and passing through 
the bars cf the iron frame it gets entangled. It is therefore of importance to 
examine the brushes frequently, and to replace new hair. Spanish broom answers 
very well in place of hair. See that it touches and sweeps the teeth of the saws 
fttUy,— keep the teeth clean and free from rust and damp. 
Prevent if possible the cutting of the seeds on the saws, as the oil stains the 
cotton. For this purpose see that the mass of seed-cotton is a! ways presenting a 
fresh surface to the saws by moving round, which it will do while there is cotton 
on it, and full enough to pass against the saws and front of the box gently with- 
out cramm'ng. — Saw ani Roller Gins may be had at Fa'^cet Co.'s, Iron 
Foundry, Liverpool. 
COTTON OIL.— Oil is got from the c:tton-5eed of America, and sent to New 
York for sale, whenever the seed is not so fresh for sowing. Cattle and goats 
are fond of the seed even three years after cleaning — ^but it should be sirged if 
anv wool remains upon it. To obtain the oil the seed must be first bruised, aud 
then either pressed, or boiled with hotwater, skimmed off and evaprrated. If 
pressed preserre the oil-cake for feeding cattle in England — where Linseed oil- 
cake is worth from £o to £6 per ton.
