Among the resources of Great Britain to which she is mainly indebted for her pre-eminence as a manufacturing nation, and without which she would not have been able to make anything like the progress she has made, or to bid defiance to foreign competition as she may always do, are her mines of coal and iron. The total produce of all the British ironworks was found, after a careful estimate, to be, in 1823, 442,066 tons; in 1825, 581,367 tons; in 1828, 653,417, and in 1830, 702,584 tons. In 1844 the quantity reached 1,500,000 tons. The quantity of tin produced in England in 1820 was 3,578 tons; in 1834 it was 4,000 tons. In addition to the quantities used at home, there was a considerable exportation of tin plates, the value of which in 1820 was about 锟?61,000, and in 1840 it was more than 锟?60,000. The produce of the copper mines in Cornwall was much greater than that of the tin mines; for while in 1820 it was only 7,364 tons, it had increased in 1840 to 11,000 tons. The increase during 60 years had been threefold, and the value annually raised exceeded 锟?,000,000 sterling. In the year 1820 the quantity of coals shipped from the port of Newcastle was more than 2,000,000 tons. In the year 1840 it had increased to nearly 3,000,000. From the port of Sunderland the quantity shipped in 1820 was considerably more than 1,000,000. In 1840 it was 1,300,000 tons. Large quantities were also shipped from the port of Stockton. The chief coal districts have naturally become the chief manufacturing districts; and as the coal is on the spot, it is impossible to estimate the quantities consumed in working the factories in Lancashire, the West Riding of Yorkshire, Nottingham, Derby, Birmingham, Wolverhampton, Leicester, Coventry, and Staffordshire. The town of Sheffield alone, it was estimated in 1835, required for manufacturing purposes about 515,000 tons of coals. Dr. Buckland, in his address to the Geological Society, in 1840, stated that "the average value of the annual produce of the mines of the British islands amounts to the enormous sum of 锟?0,000,000, of which about 锟?,000,000 arises from iron, and 锟?,000,000 from coals." The Master said, 淭he years of parents may by no means not be kept in the memory, as an occasion at once for joy and for fear.?

We went on and turned down a little street and there was another little house and we asked for Mademoiselle Bellevallee and we were sent into a little corridor and we knocked and went into a moderate sized room in which was a very large bed and a piano and a little tea table and Fernande and two others.
