ACKNOWLEDGE THE CORN. An expression of recent origin, which has now become very common. It means to confess, or acknowledge a charge or imputation. The following story is told as the origin of the phrase:
 
Some years ago, a raw customer, from the upper country, determined

to try his fortune at New Orleans. Accordingly he provided himself with two flat-boats—one laden with corn and the other with potatoes—and down the river he went. The night after his arrival he went up town, to a gambling house. Of course he commenced betting, and his luck proving unfortunate, he lost. When his money was gone, he bet his “truck;” and the corn and potatoes followed the money. At last, when completely cleaned out, he returned to his boats at the wharf; when the evidences of a new misfortune presented themselves. Through some accident or other, the flat-boat containing the corn was sunk, and a total loss. Consoling himself as well as he could, he went to sleep, dreaming of gamblers, potatoes, and corn.
 
It was scarcely sunrise, however, when he was disturbed by the “child of chance,” who had arrived, to take possession of the two boats as his winnings. Slowly awakening from his sleep, our hero, rubbing his eyes, and looking the man in the face, replied: “Stranger, I acknowledge the corn—take ‘em; but the potatoes you can’t have, by thunder.”—Pittsburgh Com. Advertiser.

“I acknowledge the Corn.”
This is the origin of the phrase “I acknowledge the corn:” In 1828 Mr. Stewart, a member of Congress, said in a speech that Ohio, Kentucky and Indiana sent their haystacks, cornfields and fodder to New York and Philadelphia for sale.
 
Mr. Wickliffe, of Kentucky, called him to order, declaring that those States did not send haystacks or cornfields to New York for sale.
 
“Well, what do you send?” asked Stewart.
 
“Why, horses, mules, cattle and hogs.”
 
“Well, what makes your horses, mules, cattle and hogs? You feed one hundred dollars’ worth of hay to a horse. You just animate and get upon the top of your haystack and ride off to market. How is it with your cattle? You make one of them carry fifty dollars’ worth of hay or grass to the Eastern market. How much corn does it take, at thirty-three cents a bushel, to fatten a hog?”
 
“Why, thirty bushels.”
 
“Then you put thirty bushels into the shape of a hog and make it walk off to the Eastern market.”
 
Then Mr. Wickliffe jumped up and said: “Mr. Speaker, I acknowledge the corn.”
