The Rough band, the Bellside band, the Calderbrae ironstone, and 

 the remnant of the Mushet black band all lie in convenient proximity 

 to the iron-works, so that the transit of this abundant supply to the 

 furnaces is already provided for bj' canal and railway. 



In the process of ii'on-smelting a large quantity of limestone is 

 used, but as this mineral is so abundant in the country as to place its 

 exhaustion beyond the reach of calculation, I have thought it un- 

 necessary to describe all the vai'ious seams of it tliat lie in and around 

 this district, on all sides. The districts of Campsie on the north, 

 Bathgate on the east, Kilbride on the south, and Hurlet on the west, 

 contain inexhaustible quantities of this mineral. The iron-works con- 

 sume about 250,000 tons a year. 



The supply of coal to these iron-works is a matter of serious impor- 

 tance. The furnaces consume annually about two millions of tons of 

 coal, being about two-thirds of the annual output of the whole district, 

 leaving only about one-third for the manufacturing and household uses 

 of the city of Glasgow and neighbourhood, and for shipment to other 

 places.
