326 Mr. Vulliamy’s Account of the Means 
workmen had got to the depth of 236 feet, the water was judged 
not to be very far off, and it was not thought safe to sink any 
deeper. A double thickness of steining was made about 6 feet 
from the bottom upwards, and a borer of 5^ inches diameter 
was made use of. A copper pipe of the same diameter with 
the borer was driven down the bore-hole to the depth of 24 
feet, at which depth the borer pierced through the rock into 
the water; and by the manner of its going through, it must 
probably have broken into a stratum containing water and sand. 
At the time the borer burst through, the top of the copper pipe 
was about 3 feet above the bottom of the well : a mixture of 
sand and water instantly rushed in through the aperture of the 
pipe. This happened about two o’clock in the afternoon, and 
by twenty minutes past three o’clock the water of the well 
stood within 17 feet of the surface. The water rose the first 
124 feet in eleven minutes, and the remaining 119 feet in one 
hour and nine minutes. The next day several buckets of water 
were drawn out, so as to lower the water 4 or 3 feet ; and in 
a short time the water again rose within 17 feet of the surface. 
A sound-line was then let down into the well in order to try 
its depth. To our great surprise the well was not found by 96 
feet so deep as it had been measured before the water was in 
it; and the lead brought up a sufficient quantity of sand to 
explain the reason of this difference, by shewing that the water 
had brought along with it 96 feet of sand into the well. Whe- 
ther the copper pipe remained full of sand or not, is not easy 
to be determined ; but I should rather be inclined to think it 
did not. 
After the well had continued in the same state several days, 
the water was drawn out so as to lower it 8 or 1 o feet ; and
