pair of shoes. A lighted candle is put into one 
hand, and a spare one suspended to a button of his 
jacket. Every part of the ordinary dress is laid 
aside, and the flannel dress worn close to the skin, 
in order to absorb the profuse perspiration which the 
closeness of the mine, or the labour of mounting the 
ladders may occasion. 
Dr. Maton (to whose excellent Observations on 
the Western Counties we are chiefly indebted for 
this information) observes, that the main vein of ore, 
which is about six feet thick, runs from east to west, 
and dips to the north at the rate of about six feet in 
a fathom. Towards the east it divides into two 
branches, and there is another that cuts the former 
nearly at a right angle, and consequently runs 
north and south, dipping to the east. We are told 
that the depth of the engine-shaft is one hundred 
and twenty-four fathoms, and that the machine 
draws up a column of water at each stroke, fifty- six 
fathoms deep and fifteen inches in diameter. At 
about fifty or sixty feet below the surface of this 
mine, the water that oozes through the different 
strata begins to form a small stream, which, if suf- 
fered to collect, would soon overflow the bottom of 
the mine: this inconvenience is effectually remedied 
by an immense steam-engine, which, as we have just 
observed, raises the water to the surface, and that 
with such force that it runs from the mine like a 
river. 
It may not be improper in this place to add a few 
particulars respecting the ceconomy of tin-mines,
