44.4 per cent came from Europe and 42.6 per cent from South Amer- 
ica. The imports from Argentina exceeded those of any other 
country and amounted to an average of more than 1,228,000 pounds 
annually. 
The average annual imports of bristles for the five years 1905-1909 
were more than 2,800,000 pounds, and during the next five years, 
1910-1914, these imports increased to more than 3,600,000 .pounds. 
China and the United Kingdom supplied 61.2 per cent during the 
five-year period, 1905-1909, and 69.2 per cent during 1910-1914. 
Large quantities also came from France, Germany, Hongkong, and 
Russia. 
Sausage casings. — Sausage casings exported in 1875 were valued 
at $135,000, which increased to more than $1,900,000 in 1893, to 
nearly $4,000,000 in 1908, and for the five years 1910-1914 the value 
ranged from a little less than 4 million to 5^ million dollars, of which 
Germany and the Netherlands received about 60 per cent during 
1910-1914» The quantity exported is only shown for the last five 
years, and ranged from 26 million to 40 million pounds. Imports of 
sausage casings for the last five years were valued at an average of 
$2,634,735 annually, of which $1,637,347, or 62.1 per cent, came from 
the United Kingdom. Three other countries — Argentina, the Nether- 
lands, and Germany — each supplied large quantities of this product. 
Bones, hoofs, and horns. — The bones, hoofs, horns, horn tips, 
strips, and waste exported in 1895 were valued at $288,000. The next 
10 years this had decreased to $181,000, and again decreased to $109,- 
000 in 1914. This product was consigned chiefly to Belgium, France, 
Italy, and the United Kingdom. 
The imports of unmanufactured bones, hoofs, and horns for the last 
five years have annually averaged over $1,000,000. These have been 
supplied chiefly by cattle-producing countries, such as Argentina, 
Canada, Mexico, and Uruguay. Argentina supplied 42.2 per cent of 
this product during the last five years. The cleaned bones imported 
for the last three years were valued at $18,512 in 1912, $40,612 in 
1913, and $5,023 in 1914. The greater portion of these were sup- 
plied by Belgium and Canada. 
Dried blood. — The dried blood imported in 1904 was valued at 
$23,671, and the value of this product did not exceed $100,000 until 
1910, when it was valued at $221,587, and increased to $391,816 in 
1914. Argentina, Australia, and the United Kingdom have been the 
source of more than half of this article during the last five years.
