As the number of pits was increafed the water augmented, 

 until at length it was judged neceflary to eredt another engine 

 with greater powers than the firft. By thefe two engines the 

 water was drained from a confiderable extent of the Yard-band, 

 Bannock-band and Main-band, feams of coals, which, being thus 

 laid water free, fupplicd the town and export market for many 

 years. 



Thk pit, called Parker's-pit, about half a mile from what is 

 called the Staith, (a place to hold a large quantity of coals) 

 which is near the harbour, was won in the Yard-band feam by 

 thefe engines. 



It was from this pit that the firft waggon-way (as it is 

 called) was laid in this county. A waggon-way is a road for 

 a waggon with four wheels to run upon. It is made with 

 wood laid down faft on each fide of the road at a proper dif- 

 tance for the folid iron wheels of the waggon to move upon ; 

 the wheels are confined from running oif from the wood by a 

 protuberant rim of iron on the interior fide of each wheel. The 

 road is made fo as to have a gentle defcent along its whole 

 length, fo that the loaden waggon runs from the pit to the 

 ftaith without any horfe to draw it ; where the defcent is fo 

 much that the motion would be too quick, a man, who is mount- 

 ed behind the waggon, by prefling down upon one wheel a piece 

 of wood, called the convoy, which is fixed to the waggon for 

 that purpofe, can reftrain the too rapid motion and regulate it 

 properly.
