The ordinary postage stamps are in denominations of from 1 cent to $1 and of nineteen kinds. The output is 40,000,000 daily, or something like thirteen billions per annum, with a face value in 1915 of $221,875,000. They are printed in sheets of 400 each, which are divided and subdivided until the sheet contains 100 stamps in which amount they are sent to the post offices for public use. The various processes used in manufacture, the printing, gumming and perforating, are separately performed on the sheets of stamps; those intended for slot machines are printed and perfected on a rotary press which performs all the operations at once. This press, the invention of Mr. Stickney, after seven years of labor, will save 65 per cent of the cost of printing stamps per annum or $280,000, and will completely revolutionize stamp printing from intaglio plates. It combines twenty-three operations in one. It prints, gums and perforates the stamps, cuts them into sections of 100 stamps each, or will finish the stamps in coils of 500 and 1,000 stamps per coil. It turns out the finished product ready for shipment to the postmasters of the country. As an object lesson to further show the tremendous proportions of this postage stamp industry, it may be stated that the daily output would cover approximately eight acres of land if laid flat or make a chain of stamps 703 miles long if laid end to end. The sheets of 100 stamps each sent to post offices in 1915, piled up one upon another, would make a shaft over 6 miles high, and placed end to end would make a strip over 16,000 miles long and as there are ten rows of stamps on each sheet, a strip of single stamps would be more than 160,000 miles long, enough to girdle the earth six times with something over. The paper required to print these stamps for the year 1915 amounted to 1,200,000 pounds, and to make this paper and to obtain this amount, 3,500 spruce trees were ground to a pulp. Converted into lumber this would have built fifty houses complete. The amount of ink required was 670,000 pounds. When the post office inspectors, unannounced, visited the Bureau at the close of the fiscal year of 1915 to check up the accounts, they were found correct to the last one-cent stamp, a high compliment to the excellent accounting system in practice at that institution. Orders for stamps are received daily from the Office of the Third Assistant Postmaster General and shipped by the Bureau. Post Office Inspectors
