Tons
From a statement of the amount of copper ore from
the mines of Cornwall and Devon sold by ticketing
in the quarter ending the 31st March, we find that
the total amount sold is 36,890 tons, which realised
192,356/. 11s. 61, giving an average price of 5/.45. 3d.
per ton. The produce is 7 81-100 per cwt., requiring
12 tons 11 cwt. of ore to produce one ton of fine
copper. Compared with the returns of the previous
quarter there is a decrease of 2,453 tons of ore,
and 17,666/. in amount. The tUirer comparison,
however, is with the corresponding quarters
of previous years. In the March quarter of 1850,
the grass amount realised was 221,0301. 19s. on
37,608 tons, giving an average price of W. 17s. 64.
per ton. In the same quarter of 1819, 36,093 tons
were sold for 188,5071. Os. lid., which shows an ave-
rage rate of 11. 6s. 91d. per ton. The present return
is therefore 718 tons, or 28,6751. 7.. lid. less than

In the corresponding quarter of 1850, 8,690 tons
were sold fur 121,7111. 65., and in 1849, 7,893 tons
realised 97,7811. Is. lid. ; so that the present return
shows a considerable decrease us compared with the
corresponding figures of the two previous years.
