stream, and began following its course upwaid tow- 

 ard this basin. At a place wliere the temperature 

 was 48*^ Celsinsf, 118.4° Fahrenheit, the rocks and 

 sticks in the water were thickly covered with dark- 

 green algss. A little higher up the temperature was 

 51° Celsius, 123.8° Fahrenheit, and algae were still 

 present, though the fumes of sulphur that rose choked 

 me as I stooped to examine the temperature. We 

 had now come to a thick jungle where the ground 

 was so soft and miiy it was both difficult and danger- •

 the natives was induced by the promise of a large 

 piece of silver to cut away the bamboos and small 

 shrubbery, if I would keep close behind him. Thus

 up, when I ordered him to turn toward the stream. 

 This hot-bog was ceitainly the next place to Tartarua

 gases, but I followed my coolie so closely that he had 

 no time to regret his agi-eement, and at last we 

 reached the bank of the stream, a place was cleared, 

 and fastening my thermometer to the end of a long 

 bamboo, I placed it in the hot, opaque water. Three 

 times I repeated the observation, and each time the 

 merexuy stood at 50^ Celsius, 122° Fahrenheit, but I 

 judged from the rate it fell after the fii'st reading 

 that it stood at 53", certainly not higher, before it 

 was raised into the air. In this spot we had unfortu- 

 nately come among hundi-eds of ants, that came out 

 and bit me until my ankles seemed to be surrounded
