in pulling the fibres, the surface of A is fluted, as represented in 

 fig. 1 ; but the flutings, and, in short, all parts, of its acting sur- 

 face, are kept very highly polished or burnished. 



The capacity of this gin on fine cotton is 125 lbs. per day, and 

 handles the fine sea island cotton (as stated by all planters and 

 factors who have used it or seen it in use,) in a perfect manner.

Machinery for Manufacturing Seed Cotton into Yarn. 

 George G. Henry, Mobile, Ala. 



The judges to whom this subject was referred reported, that 

 they examined the machinery aifecting the improvement in the. 

 manufacture of yarns, for which Mr. Geo. G. Henry, of Mobile, 

 has obtained a patent and is the proprietor of, and they find thar 

 it affects its purpose, in a manner both complete and convenient. 



A gin, constructed so as to act in connection with a lapper ot a 

 cotton factory, and a lapper constructed to act in connection wUn 

 a gin, are made, and form one machine. We have seen sfed 

 cotton, very leafy and trashy, fed to it; it gins the cotton Iroi;. 

 the seed, and the brush throws the lint on the cylinder of the 

 lapper, which j^asses it continually to the beater, and this again 

 throws the cotton to another cylinder, and thus passes the cotton 

 through rollers, which finally roll it on a beam, and makes a lap, 

 and in this form is prepared for the card. The gin is so con- 

 structed that the feed can be enlarged or diminished; and we have 

 also seen clean cotton fed to it, and a lap obtained, as before 

 described. 



Our attention was called to the fact, that in even running the 

 very leafy and dirty cotton through this machine,, the usual dust 

 and flyings of the gin, or the devil or lappers of the factory, was 

 not discernible. 



The brush of the gin throws leaf and motes down as usual, and 

 the beater also does; but it is very obvious that this machine does 

 not break up and pulverize the fibre to the point it takes in the 

 preparation, as it is broken and pulverized by the machinery used 

 in the factories to bring it to the same point, a lap. To illustrate
