form of the plant has been developed, which is capable of 
growing in ordinary dry soil. This is known as “Upland” 
and of it also there are many cultivated varieties. 
Rice differs from other grains in being completely and 
closely enclosed in its husk or hull, which must be broken 
before it can be removed. This is a far more difficult 
process than the ordinary winnowing of other grains, and 
has led to the invention of special machinery, the process 
being usually performed, in this country, in factories to 
which the crude rice is taken for that purpose. It is thus 
possible for the entire industry of rice production to be 
controlled in any given district by a combination among 
these millers, especially if the price of imported rice is 
increased by a tariff. 
After the removal of the hull, the rice is usually subject 
to a polishing process, by which the outer layers are ground 
off. This not only gives the rice a more showy appearance, 
but it removes the eggs of a fly deposited in the surface of 
the grains of most rice, which would otherwise hatch out 
before the rice is used. This process removes the most 
nutritious portion of the grain. 
As a food, rice is far less nutritious than other grains. 
It contains a very large percentage of starch, but little 
of the more valuable nutrients, fats and albuminoids. 
This is largely due to the removal of the outer layers in 
polishing. In oriental countries, in many of which rice 
is the chief food, this treatment is rarely employed, the 
rice being consumed before the insects have time to hatch.
