there. They found this supposed drv " pond tilkul by a consid- 

 erable mass of water and according- to then" estimate tive times 

 greater than the upper lake : the ouitlcs attributed the i)resence 

 of this water to the abundant rains which had truly been 

 extraordmary during the " hivernage " of 1851; they asserted 

 that during the previous lenten season this pond had been dry.^ 



The barometer here gave an altitude of 92 1 meters above the 

 level of the sea. Thus this dry pond is at almost the same 

 elevation as the upper vents of the volcano which are in a ravine 

 beyond. Nothing else was found changed in these localities 

 according to the guides, and nothing in the way of fissures nor 

 disturbances. After this last expedition our official work was 

 finished ; we had learned that the action of the volcano did not 

 extend beyond the limits we had explored, and that it was con- 

 fined to the ravine where the Riviere Claire takes its rise and 

 that immediate vicinity. It was useless to examine the north- 

 ern slope of mountain toward Macouba, for the inhabitants of 

 that quarter observed nothing extraordinary except an odor of 

 sulphuretted hydrogen, vvhich, it is said, was perceived even as 

 far as St. Marie. At Macouba the leaves of the trees were 

 coated with only the barest trace of those cinders which caused 

 such a fright in St. Pierre.
