in refervoirs built of brick, and lined with 
clay, the waters which are found in the 
higher workings. TThefe are conduéted 
upon a wheel, which, by means of a tri- 
ple crank, ie pullies, and of chains, 
moves three pumps to raife the waters of 
one pit ; and thefe run, together with thofe 
which turn the wheel, to another pit, at 
which is placed a fire- engine. Iris alfo 
farther neceflary to raife the waters which 
are colleéted in thefe deepeft parts of the 
mine, where they are at work évery day, 
purfuing the dip of the ftratum ; and they 
take the following method: 
- “Fhey Rave made, in feveral places where 
the dip is.moft regular, and the roof moft 
folid, a double waggon-way, like thofe 
upon the furface, only fmaller: the four- 
wheeled carriages, which go upon thefe 
ways, are fimply a box, made water- 
tight, and higher behind than before, in 
proportion to the dip of the ftrata; fo 
that tne upper furface is always horione 
tal; and it is clofed exaétly with a lid, 
thatthe water may not be loft. It has a 
valve in the bottom, which is eafily open- 
ed by a lirtle [Fr. warlet] placed above 
the li id, in the manner deferibed below. ~ 
At the upper end of the waggon-way 
is.a gin, from which, by means of pulleys, 
2 ftrony rope is carried along the maddle 
of each. way, fupported all along by fmall 
wooden rollers ; there are two horfes in 
this gin, which draw up the carriages 
from a diftance of two hundred fathoms — 
more or lefs, according to the fituation. 
At the lower extremity of the road, where 
the waters colleét,a workman is conftantly 
vaifing them, by a common pump, intoa 
arge “ciftern ; from which they are con- 
veyed by a cock, into the body of the car- 
riages, when they arrive at the place. 
When a carriage is filled, the workman 
blows ahorn, the found of which may be 
heard at the gin. Then the boy who 
driv es the horfes, fets them a- -going, and 
thus ‘brings up a carriage full of water, 
Ww hile an empty one is defcending by the 
other. w ay. When it is near the place 
where the valve is to be opened, it meets a 
piece of wood, which, by the help of a 
cord, rings a bell placed near the horfes, 
which immediately ftop, The boy then 
he ai is them gently, and knows the number 
cf fteps which they haye to make, to ar- 
rive at the place where the carriage is to 
empty ifelf. Over the referyoir which i is to 
reccivye the water, theré is a fmall wooden 
rolle r, at which, when the chariotis arrived, 
the warlet [Q. clack] of the valvé meets 
the roller, which ‘overtets it, [ Fr, feefaws]

the carriage goes no farther. The car- 
riage is prevented from running back, by 
a forked iron drag; but for greater fecurity, 
there is a fort of barrier, which itops the 
carriage at this place, and gives notice to 
the horfes, who walk very flow from the 
moment that they heard the bell, The boy 
then goes to the place where the carriage 
has emptied itfelf, takes up the iron-drag, 
and puts it on a hook ; he waits till the 
found of the horn informs him that the 
other carriage is full, on which he returns 
to his horfes, drives them in a contrary 
direétion, and brings the loaded carriage 
up the other waggon-way, while that which 
has juft been emptied, defcends. 
In places where they are working, they 
have carriages compofed of two chelts, one 
for bringing up the water, the other for 
drawing the coal, There are alfo fome 
which bring up only coal. 
In places where they are working upon 
the direétion (or level) of the feam, they 
conftruét waggon-ways for four-wheeled 
carriages [at ‘Ne weafile called trams] upon 
which they place the batkets [corves]. 
Thefe are drawn to the pit by horfes, in 
order to be raifed to the furface. All the 
coal is raifed by pits from one bed to the 
other; for which purpofe, many gins are 
creéted within the mine. ‘There are alfo 
many places where as yet no waggon -Ww2ys 
are made; and here they place the corves 
upon fledges, which, according to the 
nature of ioe place, and i its diftance from 
the pit, are drawn by men or by horfes.
