THE RECENT ERUPTIONS OF CO LIMA 76 1 



of the volcano, no more than four or five kilometers from the 

 crater, where they do no harm. The pebbles and the sands, 

 which have rained upon the low and populated districts, have 

 caused no damage to persons or to cultivated fields. 



7. The existence of solfataras in this volcano has not been 

 proved ; sulphur probably forms no part of its emanations. 



8. The scoriae and sands which issue from the crater are 

 stopped in their course by the barrancas (gorges) which exist 

 about half-way up the cone ; these barrancas, existing on all sides 

 and at various altitudes, serve as receptacles and protectors. If 

 the higher ones are filled up, the lower ones receive the dis- 

 charge. As the material is uncompacted, it is easily removed 

 and the barra?icas are cleared by the later rains 



9. As there are no signs that the eruptive power of Colima is 

 augmenting, the inhabitants of the neighboring country may live 

 tranquil 



10. The most violent eruptions have agitated the air sufifi- 

 ciently to produce loud explosions, but have not caused earth- 

 quakes.
