Rice contains less fatty matter than any other grain, and the 

 greater portion of the fat is contained in the outer coats. John 

 ston found in the siftings or cleanings of rice, from 5 to 5 per 

 cent, of fatty matter.

Varieties of rice from India give a much larger per centage 

 of ash than those grown in the United States. This grain is 

 probably less nutritious than any other ordinarily used by man ; 

 as it contains a comparatively small proportion of glutinous or 

 nitrogenous matter. 



325. The soil adapted for the common rice is of a marshy 

 and wet character, containing much organic matter, which can 

 be overflowed or drained when requisite; but it will grow 

 (though less profitably) on light, moist uplands without irriga 

 tion, when cultivated with the hoe or plow. On wet lands, the 

 embankments and ditches being prepared, the soil is well 

 plowed, the seed sown at the rate of If io 2j bushels per acre, 

 and harrowed in with a light harrow, thickly set with teeth. 

 In South Carolina, from April to May, is the usual season. 

 Immediately after, the water is let on, so as barely to overflow 

 the ground. As soon as the grain begins to swell, the water is 

 withdrawn. When the plant is three inches high, the water is
