the middle portion is sold as block tin, and the lowest portion must be 
further refined. Average English refined tin is from 98.64 to 99.76 
per cent pure. The cost of refining tin in the Straits Settlements is 
said to be about $12 per ton of 2,000 pounds. There is always some 
loss in smelting tin; slags from the furnace seldom contain less than 
5 per cent, and the average loss in smelting is said to be about 9 per 
cent. 
PRODUCTION AND VALUE OF TIN IN 1902-3. 
During the years 1902 and 1903 the total world's production of tin 
is estimated at 90,233 and 92,530 long tons, respectively, as shown by 
the following table. a

Net increase, 2,303 long tons. 
Of this total production only about 30 tons were mined in the 
United States. 
The total consumption of tin in the United States approximated 
39,000 tons, or 13 per cent of the world's output. The production of 
tin last year, as in fact for several years past, has hardly exceeded the 
consumption, and from some of the older districts, especially Banca 
and Billiton, there are signs of a diminution in the output. The 
average price of tin in New York for 1903 was 28.09 cents per pound, 
or about 1^ cents per pound higher than for 1902. The price varied 
during the year from 25.42 cents to 30.15 cents per pound. The total 
amount of tin consumed in the United States was worth at market 
prices over $24,500,000. 
VALUE OF TUNGSTEN AS A BY-PRODUCT. 
Tungsten ores in the form of wolframite occur in association with 
the tin ores in several places in the York region. At present prices 
these ores in the York region evidently have no commercial value, but
