“5. One foot of a compact greyish-blue earth.
“6. In tapping this bed, which was four feet nine inches in thickness, and consequently at a depth of about twelve feet, water was first met with. It was found by comparison that the level of the water in the boiling mud spring coincided at this time with that of the water thus discovered. The heat was now very great, and a constant hissing and bubbling could be heard as proceeding from the bottom of the hole which had been made.
“7. Nine inches of greyish-blue earth.
“8. One foot six inches of a similar unctuous earth, containing many small white stones. This was the hottest layer of any yet pierced; the buzzing, humming noise was now much louder than before.
“9. Three feet of the same kind of clay, but much harder and more compact; this layer was also full of small, round, white stones.
“10. Six inches of a violet tinged earth, very greasy to the touch. In this bed the heat sensibly diminished.
“11. One foot six inches of red and blue clay intermingled. The heat continued to diminish very fast.
“12. One foot of reddish-looking clay, the temperature remaining about the same.
“13. Six inches of yellow and red clay.
“14. One foot of a greenish coloured earth, much less coherent than the previous layers. Here the heat again began to increase.
