Large quantities of starch are now made from this grain in Ohio; an establishment near Columbus consume 20,000 bushels of corn annually for this purpose.  The offal of the grain is given to hogs, 500 to 600 head being annually fattened therewith.  The quality of the starch is said to be superior to that of wheat, and commands a higher price in New York.

A corn plant, fifteen days after the seed was planted, cut on the 3rd June close to the ground, gave of—­

Water                 86.626
Dry matter            10.374
Ash                    1.354
Ash calculated dry    13.053

By the above figures it will be seen that nearly 90 per cent, of the young plant is water; and that in proportion to the dry matter, the amount of earthy minerals which remain, as ash, when the plant is burnt, is large.  This excess of water continues for many weeks.  Thus, on the 5th July, thirty-three days from planting, the relations stood thus:—­

  Water 90.518
  Dry matter 9.482
  Ash 1.333
  Ash calculated dry 14.101
  (Ash very saline.)

Before green succulent food of this character is fit to give to cows, oxen, mules, or horses, it should be partly dried.  Plants that contain from 70 to 75 per cent. of water need no curing before eaten.  The young stalk cut July 12, gave over 94 per cent. of water.  Such food used for soiling without drying would be likely to scour an animal, and give it the cholic.

The root at this time (July 12) gave of—­

  Water 81.026
  Dry matter 18.974
  Ash 2.222
  Ash calculated dry 11.711
  (Ash tastes of caustic potash.)

Ash of the whole plant above ground, 6.77 grains.  Amount of ash in all below ground, 3.93 grains.

So late as July 26, the proportion of water in the stalk was 94 per cent.; and the ash calculated dry 17.66 per cent.  The plant gained 21.36.98 grains in weight in a week preceding the 6th September.  This was equal to a gain of 12.72 grains per hour.
