UNITED STATES. 



. end of August. In general, the produce of rice is 

 from 1200 to 1500 lbs, to the acre. 



The rough rice is carried by a set of elevating 

 buckets, from the lower, into the upper story, of the 

 machine house, from whence it falls into a rolling 

 screen; which separates the sand and gravel from 

 it; and pours it clean into the hopper. From the 

 hopper it passes to the mill stones, where the chaff 

 is separated from the grain, and is afterwards blown 

 away by a wind fan. The milled rice is then dis- 

 charged into a bin, placed above the mortars, hav- 

 ing funnels communicating therefrom to the mortars. 

 The rice is then introduced into the mortars by the 

 funnels, and is there beaten by pestles weighing 

 about 230 lbs. which strike the rice from 32 to 44 

 times in a minute. When the rice is sufficiently 

 beaten, it is taken out and throwm into a hopper, 

 from whence by a set of elevating buckets, it is car- 

 ried up to another rolling screen, where the small 

 rice and flour are separated from it. The whole 

 rice then passes through a funnel, under the friction 

 of a brush, which takes off any flour which may still 

 . acjhere to the grain ; it thence falls into a wind fan, 

 which winnows it clean, and discharges it into a bin. 

 from whence, by funnels, it is received into barrels ; 

 and in some mills is even packed in them by mecha- 

 nical operation. The dispatch and neatness of the 

 v^^ork done by these mills, is extremely pleasing; 

 particularly when we consider the small attendance 

 necessary for working them. 



The cotton of the United States may be ranged in 

 three classes, viz, nankeen^ green scecl^ and black
