It is for them to prove that _production_ and _sale_ are synonymous terms, which if they cannot do, I have a right to accuse them, if not of playing upon words, at least of confounding them.
Let me be permitted to exemplify my idea.
Suppose that several New York speculators should determine to devote themselves to the production of oranges.

They know that the oranges of Portugal can be sold in New York at one cent each, whilst on account of the boxes, hot-houses, &c., which are necessary to ward against the severity of our climate, it is impossible to raise them at less than a dollar apiece.

They accordingly demand a duty of ninety-nine cents upon Portugal oranges.

With the help of this duty, say they, the _conditions of production_ will be equalized.

Congress, yielding as usual to this argument, imposes a duty of ninety-nine cents on each foreign orange.
Now I say that the _relative conditions of production_ are in no wise changed.
