of Mount Etna, in 1819. ^31 



gmoke vomited from the diiferent mouths at the time of the 

 eruption. This circumstance caused many who observed it 

 from a distance to believe that a new aperture was formed in 

 that place. The original high mouth, or truncated cone, does 

 not send forth any more cinders or smoke, neither are the 

 roarings heard so strongly as at first. TPie lava occupies little 

 space in the valley di Calanna ; it is exactly between the Acqua 

 Grande, and Acqua Rossa. The smoke, mixed with dust, ascends, 

 as yesterday. 



26</t. — The lava does not advance more than sixteen feet an 

 hour ; at 5 p. m., smoke is discharged from the higher mouth, 

 mixed with the finest sand, which falls at a great distance. 



27ih. — The lava runs to day much quicker in the above-men- 

 tioned valley, having increased in quantity, by the junction of 

 several small streams. The smoke, mixed with sand, continues, 

 and is driven, by the force of the wind, beyond Cape Pachino. 

 It is singular, that no smoke appears from the great crater. 



28</t. — The cone is swallowed up on the north-west side, 

 opposite the high Bicorne, so that the explosions of scoria 

 come from the enlarged mouth, and the smoke and sand from the 

 broken cone itself. Towards five in the morning — the west wind 

 forces the smoke and sand on the other side, so that we are thus 

 liberated from these dismal and severe showers. All the vicinity 

 of the original higher mouth, which had been, until to-day, 

 covered with a quantity of scoria and fragments of stones, upon 

 which it was not possible to walk without danger, is now covered 

 by the sand that has fallen there, in such a manner, that it re- 

 mains level, like the surface of tlie Piano del Lago. The lava 

 does not make so much progress in the valley di Calanna. 



30i/t, and July \st. — The lava in the above-mentioned valley has 

 ceased to advance ; in the night, at ten minutes before twelve, an 

 earthquake was sensibly felt, but more in Catania than upon Etna. 

 The motion seemed to oscillate from south to north. 



2nd. — The lava within the valley di Calanna begins to cool, 

 and the highest mouth roars but seldom.
