APPENDIX I 



Aluminium, with Special Reference to Use for Electrical 



Energy Transmission 



The aluminium industry began in a very modest 

 Historical manner in the early 'eighties' of the last century. 



Several factories were operated on the St. Claire 

 Deville method, of which the one at Salindres, France, produced 2^ 

 tons of aluminium annually. The production increased only slowly 

 to begin with, as will appear from the appended table* showing 

 the world's production in metric tonsf: — 



1880 2.4 1907 19,800 



1885 13 1908 18,600 



1890 175 1909 31,200 



1895 1,426 1910 43,800 



1900 5,000 1911 45,000 



1901 6,900 1912 61,100 



1902 8,350 1913 78,790 



1903 8,200 1914 84,857 



1904 9,300 1915 86,394 



1905 11,500 1916 112,626 



1906 14,500 1917 173,500 



In a reviewj of the international aluminium industry, published 

 in 1917, it was stated that the demand for aluminium had increased 

 greatly during the last few years. While the German, Swiss, French, 

 and British works have had difficulty in extending greatly under 

 war conditions, the aluminium industry in the United States has 

 made enormous progress. The world's production of aluminium 

 during 1917 is estimated at 173,500 metric tons, and, if the extensions 

 and new constructions now in process of execution are taken into con- 

 sideration, the capacity will increase to 200,000 tons in the near future. 

 Such a large production would prevent excessive prices of aluminium, 

 but it is questioned whether sufficient supply of alumina, bauxite, 

 cryolite, etc., will be on hand in time to produce 200,000 tons.

 from Metallgesellschaft, 1903-1912, p. 16; for 1912-17, from Mineral Industr 

 during 1917, p. 10. 



fThe metric ton is 2,204 lbs, but, as these statistics are only close approxima- 

 tions or estimates, it is assumed to be 2,200 lbs.
