LSeptembeb, 



The quantity of coal carried inland by means of railways has 

 i..LTeased. 



The saving- in coal supplied to the city of York, in consequence 

 of Mr. Hudson's railway measures, is not less tlian £30,000 yearly. 

 _ In the south-east of England, which is supplied mostly from the 

 Nortliumherland and Durham coal-fields, the quantity carried up- 

 land by railway may be reckoned as follows: — 



1845, 120,000 tons. 



1846, 162,000 „ 



1847, 240,000 „ 



How trivial this is, may be seen from the quantity of coals im- 

 ported into London, which is thus shown. 



1825, 1,921,091 toni. 

 1835, 2,299,816 „ 

 1845, 3,461,199 „ 



It will be seen that in the supply of the inland districts the rail- 

 ways have proved very effective ; but they have as yet done very 

 little for those districts which are supplied from the sea. This 

 must be attributed to the inability of the railway companies to 

 arive their attention at present to this branch of traffic ; but when 

 they do, a complete revolution must be effected in the supply of 

 coals. The only lines from which we have detailed returns are the 

 Soutli Eastern and South Western, which show a great increase in 

 the (juantity of coal carried. There is every reason to believe that 

 a great traffic is growing up in the Eastern Counties district — not 

 less than 85,000 tons: but the returns do not show this fully. 



No. IV.— COKE TRAFFIC. 



The traffic in coke must be considerable in some districts, but 

 there is a want of detailed returns. It is a lucrative branch of 

 revenue to the Midland Railway Company. 



Tlie following shows the traffic in coke in each year on the 

 under-mentioned lines : —

No. v.— IRONSTONE AND IRON TRAFFIC. 



These form great branches of mineral traffic, but the extent of 

 tliem is very imperfectly expressed in the returns. 



The traffic in ironstone on the following railways in the years 

 ending June 30, 1845, 1846, and 1847, is shown below in tons.

The rates charged for the conveyance of ironstone and iron-ore 

 are as follows : — 



* Eltimsted amouDt. 



* Imperfect returns. 

 The iron carried is mostly pig-iron. 

 The rates for the carriage of iron are as follows :- 



Ballochney, .. 



Lancashire and Yorkshire, 



Marvport and Carlisle, 



Tali'Vale, 



M'isliaw and Coltness,

A considerable quantity of dross and slag are cirried, but there 

 are only returns on the Wishaw and Coltness railway : —

* Half-year, 45,261 tons, 1,002(. t Half-year, 544 tons, 171. 



The rateg for carrying dross are l-i2d. per mile per ton, and for 

 carrying slag l*35rf. per mile per ton. 



The traffic of the Glasgow iron district in coals, limestone, iron- 

 stone, iron dross, and slag carried by railway was in 1846 and 1847 

 as follows : — 



1846. 1847. 



Tons, 2,500,000 2,900,000 



The traffic of the Welsh iron district in coals, limestone, iron- 

 stone, and iron, stands as follows : — 



1844. 1845. 1816. 1847. 



Tons, 212,000 323,000 390,000 441,000 



The traffic of the Furness iron district consists solely in the 

 shipment of ironstone to South Wales, to the e.xtent of 106,301 

 tons in 1847. 



No. VI.— COPPER AND TIN TRAFFIC. 



The traffic in copper and tin ores is confined to the Cornish lines. 

 There are no data now to show this. In 18 lo I estimated it as 

 follows : —
