[Note 3] p. 48.—Economic value of eider-down.
According to Stejneger, each nest yields about an ounce and a third. From Greenland and Iceland alone, six thousand pounds, or the contents of seventy-two thousand nests, are yearly exported. Nordenskiöld notes that the quantity of eider-down brought from the polar lands to Tromsöe amounted in 1868 to 540 kilogrammes, in 1869 to 963, in 1870 to 882, in 1871 to 630, in 1872 to 306, and that the total annual yield may be probably estimated at three times as much.
