1863. ] The hot springs of Pai in the Tavoy district. 385 
steam which seemed to give off the greater portion of the clouds of 
steam overhead. It rushes out of a hole nearly midway down a cas- 
cade some 6 feet high, with a noise precisely like that of a steam-jet, 
and with such force, that it drives the water of the cascade horizontally 
out 4 or 5 feet. The water which issues from this hole with the steam, 
or at least comes into contact with the steam, was hot enough te boil 
an egg well enough to eat, in 38 minutes. ‘There are several holes 
in the pools above this cascade, but all within 15 yards of it, from 
which hot water bubbles up. The stream above the pools containing 
these bubbling holes, is cold, and the water, close to and around the 
upper or higher holes of the stream, is also cold. The holes from 
which the hot water spouts up are all small: the water from them is so 
hot, that we boiled eggs in all of them, fit to eat in 3 minutes. No 
steam arose from these holes. Thestream itself there is a cold stream, 
until it reaches the hot water springs or holes: from these, jets of hot 
water spout up into it, and the water below them becomes warm at 
once: below the cascade it is hot and continues so, as we proved, for a 
quarter of a mile ; perhaps further on. You will observe that Mason 
records that the temperature of these springs is 198°. We all 
thought it that, if not higher. By an unfortuyate mischance we 
had not a thermometer with us. The water had no unpleasant taste 
or smell. 
There are other large and small jets of steam below the cascade ; 
one about 380 yards lower down is a remarkable one. It escapes 
in a broad column from under a rock with the loud sound of an 
engine blowing off. All the rocks (granite) about the hot water 
are hot: and the ground on which we slept, about 30 yards from the 
stream, and several feet higher than it, became very hot under our 
beds at night. We removed some stones and found the ground hot 
beneath them. We dug a hole near our beds, and steam began to rise 
from it at 8 or 9 inches from the surface of the ground. Two of our 
party heard a rumbling sound several times during the night, which 
may have been thunder, but which appeared to us to be subterranean. 
We walked only about two miles of the way back, and descended 
the rest of the distance in small bamboo rafts, (12 bamboos about 
20 or 22 feet long), to Par Dap: water distance, about 12 miles: 
time occupied, nearly 4 hours. About half way down we collected the 
water in the Soda water bottle, and the labelled stones, on the left
