1863. ] The hot srings of Pai in the Tavoy district. 383 
Account of a visit to the hot springs of Pai in the Tavoy district. 
Ly Capt. J. F. Stevenson, Deputy Commissioner. 
(Communicated by T. OLDHAM, Esq., F. R. 8.) 
T have the pleasure of sending with this letter, a case containing four 
quart bottles of water and conferve, one soda water bottle of the same, 
and two packets of stones, which I collected a few daysago at the hot 
springs near Paz in this district. 
The four quart bottles ant the packet of stones not labelled, are 
all from the remarkable springs which I believe to be partially, 
(but I should say inaccurately,) described in Mason’s Tenasserim, 
page 18. He says that “ According to Phillips they are hotter than 
any on record out of volcanic regions, ‘with the questionable excep- 
tion of three springs in China, which probably exceeded the tempera- 
ture of the air from 70 to 120 degrees.’ The principal spring at Pai, 
—for there are several, is in alittle sandy* basin in the midst of granite 
rocks, on the margin} of a cold water stream, where it bubbles up 
from three or four vents, and on immersing the thermometer into 
one, the mercury rises to 198°, within fourteen degrees of boiling 
water. Its location is ratber peculiar, not being in a valley like the 
others I have seen, but on the side of a hill more than a thousandt 
feet above the level of the sea, and surrounded by large masses of 
coarse-grained granite recks, which seem to have been detached from. 
the summit above.” 
These springs are in a small mountain stream called by the people, 
the hot-water stream, (Ye boo Hkyoung,) and about 2 miles from 
the Pai river. 
The soda-water bottle and the second packet of stones are labelled. 
They are from a small spring on the bank of, and quite close to 
the Paz river. 
The Paz river is about 65 miles south from Tavoy town, near 
the Mergui boundary. It rises in the range of hills which intersects 
this district between the Tenasserim and the Tavoy river valleys,
