' A society for the education of the blind has been lately

 land from the sudden rolling down of huge fragments of 

 rock and other component parts of the mountains in the

 Subterranean passages, or by the medium of the atmo- 

 sphere ? How does it happen that the above unusual phae- 

 nomena take place at the same moment i"
