from the seed and does not cut or tear it off, consequently the 
quality of the cotton is better ; that it produces a greater per- 
centage of lint by cleaning the seeds more perfectly, and does 
more work in a given time than a saw-gin. The brush is made in 
parts and can be easily repaired. It is not made with a self-feeder, 
which, however, might be easily added, but there is not the same 
risk of serious accidents with the needle-points as with the ser- 
rated-saw teeth. The sizes vary from 30 to 60 circles, and the 
price, with condenser, from 237 to 420 dollars. 
My readers will be interested to learn some particulars about the 
machinery for removing the shell and cotton from the cotton-seed, 
which operation results in an article of cattle-food increasingly 
appreciated, viz., decorticated cotton-seed cake. Although this 
trade is a large and extending one, there was only one exhibitor 
of such machinery, Mr. David Kahnweiler, of 120, Centre Street, 
New York, who showed 
several different sized 
machines. That which 
I shall endeavour to 
describe is known as 
the Plantation Huller : 
a two horse - power 
machine, specially de- 
signed to supply a very 
useful position on plan- 
tations where hitherto 
the cotton-seed has been 
supplied to the cattle 
just as it comes from 
the gin, with shell and 
cotton, much to the 
injury of the animals. 
Indeed if such indi- 
gestible matter is passed 
through the system, 
little nourishment can 
be obtained from the 
food, as the shell would 
resist the most powerful 
digestion. 
The annexed ' illustration 
(Fig. 54), showing a section 
of the machine, will enable 
the reader to understand the 
mechanism. 
The feed-roller C is of cast iron in small sections, the surface is toothed or
