ELECTRICAL CAUSES OF TIE EARTHQUAKE

SIR On the 10Th of August, 1854, pointed
mt IN the co ums of THE TRIBUNE certain indications
tending to that the Of the earthquake then
felt were rather than volcanic 1t was observed
thai previous and the EARTHQUAKE IN England the
cables had much troubled By electric storms Ger
tain pecuariies in the phenomena OF yesterday seem
TO support this theory. Downtown In New lorK tue
,hock was distinctly felt. Here the soil is sand and
gravel with large bouders Around Union square

there had been any sucn III
fourh-s, in fifth fat, tremor of any kind was per-
cepble. Again, IN Brooklyn. a. in 1884 the shaking
was greater than Ia New-York II the shocks are the
result Of the passage OF wave OF electricity from one
area Of tho earths crust another the difference OF
movement may lie accounted for by the difference OF
geological formation Tho current Wou!a pass go
through rocky formation, causing but little mOvement
