than in the previous year. 
Iron. — The Iron Ore produce of Yorkshire is especially 
important. The remarkable district of the North Riding, 
which has formed the subject of Professor Phillips's lecture, 
yielded, in 1857, the following quantities of Ore : —

The produce of these districts, in 1856, was 1,197,417 
tons, showing an increase of 216,738 tons. 
The distribution of these Ores along the lines embraced 
by the North Eastern Railway is interesting and important. 
For this and other Mineral returns I am especially indebted 
to Mr. Kitson, of Leeds, one of the directors, and to
