Nobody can.

People that want to, can go to the expense and trouble of shipping their oils to Europe and back--it's their privilege; but our firm knows a trick worth six of that.

We turn out the whole thing--clean from the word go--in our factory in New Orleans: labels, bottles, oil, everything.

Well, no, not labels: been buying them abroad--get them dirt-cheap there.

You see, there's just one little wee speck, essence, or whatever it is, in a gallon of cotton-seed oil, that give it a smell, or a flavor, or something--get that out, and you're all right--perfectly easy then to turn the oil into any kind of oil you want to, and there ain't anybody that can detect the true from the false.
