■which is only capable of carrying one tub, and runs in iron mre gaiides In 

 order to work the new shaft efficiently, a 3G-inch double cylinder engine has been 

 put down, with a 20-feot winding drum ; and the head-gear, which is in course 

 of construction, will, when complete, be some 60 feet high. The columns and 

 girders are of iron, and were made by the Whitehaven Shipbidlding Company. 

 They are, however, being put up by the Granary Yard hands, under the super- 

 vision of Mr. Hetherington. Hitherto the ventUation of William Pit has been 

 by furnaces, but the ventilation of the Whitehaven collieries on the south side 

 having been so successfully adapted to the French patent known as Guibal's fan. 

 it has been determined to ere(;t one for the ventilation of both Henry Pit and 

 William Pit. On visiting the fan case we found that it was in a forward state, 

 and when complete, the present shaft into William Pit will be converted into an 

 air shaft, and the whole of the coals will be drawn from Henry Pit. At present 

 Henry Pit is being ventilated by a small Guibal fan, some 10 feet in diameter, 

 and will be driven by a 30-inch double cylinder, disconnecting engine. The 

 steam to drive the winding engine and the fan engine will be generated in five 

 large boilers immediately against the face of Bransty quarry, and the flue goes 

 to a chimney which has made its appearance in the field above. Amongst other 

 improvements on the pit top has been the erection of new screens. The whole 

 of the frame work is made of iron, and when complete wUl be very commodious ; 

 and as soon as Henry Pit shaft is ready to draw the whole of the coals a new 

 inclined plane from the pit top to the screens wUl come into operation. The 

 tubs will rvtn upon an inclined plane, both from and back to the pit top, a steam 

 lift at the screen end raising the tubs a sufficient height to enable them to find 

 their way back to the pit top alone.
