PLATINUM AND ALLIED METALS.

EXPORTS.
Exports of platinum, as recorded by the Bureau of Foreign and Domestic Commerce2 in 1920, were 1,302 ounces of unmanufactured platinum, valued at $177,115, and manufactures of platinum to the value of $111,014. The exports of unmanufactured platinum were 200 ounces to Canada and 1,102 ounces to Japan. All the manu­factured platinum went to Japan.
CONSUMPTION.
The following tabulation of the information supplied by dealers as to the consumption of platinum, iridium, and palladium in the various industries is of interest in showing the changes due to changed conditions. The jewelers continue to use more than half of the platinum metals consumed, and the electrical industry 19 per cent. The use of palladium-gold alloys by jewelers apparently diminished greatly, for this industry used only one-third as much palladium in 1920 as in 1919.
The total consumption of these platinum metals in 1920 decreased approximately 9 per cent from the consumption in 1919 but increased 22.4 per cent over the consumption in 1918.
Platinum, iridium, and palladium used in the United States in 1918-1920 by consuming industries, in troy ounces.
The consumption of these platinum metals can be arrived at in another way, as is shown in the following table. In using this method, because of the inexactness of certain of the tariff classifica­tions, assumptions have to be made that can not be verified, yet it is of interest to compare the results obtained by the two methods, which check for the year 1920 within approximately 1,000 ounces, or an error of less than 1 per cent.
