Kilaiica and Manna Loa. 



rower and thicker stream liad formed a crust and become black in less than a quarter 

 of the distance. In places the lava met upward inclines, then the cooling, but still 

 flexible, crust, made a dam and carried the fluid part up and over a rise of some feet. 

 The little lava spring was an epitome of a full lava flow, and was more instru6live 

 than the immense fiery floods that from time to time break out from these volcanoes 

 and flow for many miles. Later in the evening this insignificant flow became more 

 active, covering twenty acres and giving more light than the lakes themselves. 



FIG. 84. HATH HOUSE ON THE SUI<PHUR B.\NK, 1S80. 



Over one of the steam cracks near the Volcano House, on the northeastern bank, 

 and in close proximity to what remained of the sulphur bank, had been built a very 

 rude steam bath. A hut of ample dimensions, a box with a stool in it, and loose boards 

 to fit around the neck of the bather, with a wooden sluice from the steam crack to the 

 box and a slide to regulate the admission of steam, constitute the entire apparatus. 

 Seated in the box late that evening, in utter darkness, while the attendant had gone 

 outside with the lantern to get a pail of cold water, I heard, in the stillness, sounds 

 deep down in the steam crack, rumbling and hard noises totally unlike the soft hissing 

 or sputtering of the steam. Fearing that my imagination lent strength if not being 

 to these sounds, I went to a crack outside and, at the risk of pitching in head-first, 

 listened carefully. The same noise was heard distinctly, not unlike that of an earth- 

 quake, but feebler. [520]
