Meyer v. Arthur
ERROR to the Circuit Court of the United States for the Southern District of New York.
This is a suit to recover import duties alleged to have been unlawfully exacted by the defendant, the collector of the port of New York. The articles on which they were charged were white lead, nitrate of lead, oxide of zinc, and dry and orange maineral, imported after the first day of August, 1872. By the second section of the act to reduce duties on imports, passed June 6, 1872, 17 Stat. 230, it was provided that on and after the first day of August, 1872, only ninety per cent of the duties theretofore imposed should be levied upon certain enumerated articles imported from foreign countries; amongst which were the following, as described in the words of the act:--
'All metals not herein otherwise provided for, and all manufactures of metals of which either of them is the component part of chief value, excepting percussion-caps, watches, jewelry, and other articles of ornament;' with a proviso excepting certain kinds of wire-rope, and chains made of steel wire.
The following facts appeared in evidence upon the trial.
Oxide of zinc is manufactured in European establishments, as follows:--
Sheets of zinc ordinarily sold in commerce are placed in retorts. The face of the retort has an opening large enough to admit the sheet. The backs of the retorts are enclosed in a furnace, and the retorts are heated by bituminous coal to a white heat. The action of the heat vaporizes the spelter, which is entirely consumed. The vapor passes out of the mouth of the retort into large pipes, into which currents of air are forced. The vapor combines with the oxygen of the air, and becomes white, snow-like flakes. The current bears these flakes along through the pipes, which terminate in long chambers. At the mouth of the pipes bags are suspended, in which the flakes are caught. No further process is required.
The oxide of zinc in suit was manufactured in this way.
Nitrate of lead is a chemical combination of lead and nitric acid. Lead previously melted and cooled is placed in a vessel filled with dilute heated nitric acid, and subjected to a slight additional heat. The nitrate of lead is formed in crystals upon the side of the vessel. Its form as a commodity in the market is ordinarily that of a white, opaque crystal.
Orange or red lead is made by roasting dry white lead in a furnace, and exposing it to the air which is admitted into the heated receptacle. By this process the white lead loses a portion of its carbonic acid, and absorbs oxygen from the air. Orange or red lead is used by paper-stainers, manufacturers of wall-paper, and for highly-colored cards.
White lead is manufactured as follows:--
Small earthen pots are partially filled with vinegar or acetic acid. Pig-lead of commerce, cast into round perforated plates technically called buckles, are placed in the pots above the acid, and not in contact with it. The pots thus filled are placed in a chamber upon a layer of spent tan-bark. Alternate layers of pots and tan-bark are filled up to the roof of the chamber: air is introduced into the chamber through flues and natural crevices. The tan contains moisture, becomes heated, and evolves carbonic acid. By chemical action the lead is oxidized by the oxygen of the air, and then, in combination with the carbonic acid, becomes a carbonate of the oxide of lead.
The acetic acid does not touch the lead; but its presence facilitates the process of oxidation.
In the course of three months the lead has generally become entirely oxidized, of a white color, but retaining its original shape of a buckle. It is then crushed in rollers, any uncorroded pieces of lead having first been separated from it, then ground and dried. Then, if it is to be sold in oil, it is reground with linseed-oil.
An analysis of the articles in question gave the following results:--
OXIDE OF ZINC.
.......... .100.
ORANGE MINERAL.
acid ......9.
DRY WHITE LEAD.
WHITE LEAD IN OIL.
