IMPROVED FAN MILL. 



Junction, Rensselaer Co., Jfov. 23, 1846. 



Mr. T. B. Wakeman — Yours of Nov. 1st, informing us that we 

 were awarded the first premium of a silver medal, at the late Fair of 

 the American Institute, for the best fan mill, has been duly received. 

 The required description may be given in a few words. 



The mill is the ordinary size and construction, as to the exterior ; 

 the interior is a new improvement. It is used to clean all sorts of 

 grain and seed raised in this country. Its cost is, for No. 1, with 7 

 sieves, 16 by 19 inches, $21; up to $27, for size No. 4, with 7 

 sieves, 19 by 22 inches. 



They are as durable as cotton machinery, with the same care; easy 

 to be repaired. The amount of labor saved is one-half, as it cleans 

 all kinds of grain and seed clean with one operation. It is the only 

 mill known to the inventor, that will take cockle, chess, and smut 

 from wheat, at the same time it is chaffed. 



Your ob't servants,

MANUFACTURE OF UNROTTED HEMP. 



Louisville, February 23, 1847. 



Dear Sir — You made an inquiry of me, some time since, in rela-

 the necessity of doing so, in the staple, can be obviated, or is render- 

 ed unnecessary, I herewith inclose a sample of unrotted hemp, to es- 

 tablish the fact. 



I have been engaged with others, for some years, in perfecting 

 machinery that would break and clean unrotted hemp, feeling con- 

 vinced that if the article could be so obtained, it v.'Ould prove in 

 cordage, or fabrics, much stronger than that obtained by the uncer- 

 tain process of either dew or water rotting. 



You will find, on examination of the sample herewith sent of un- 

 rotted hemp, that it has the singular property of being drawn into a 

 very fine sliver, or fibre, this you can prove, by taking hold of the 

 two ends of the sample, and drawing them until the elongation com-
