is inclined to think that they were the deposits of a great 
river of the past, occupying the bed of the present Klamath, 
but having its debouchure here. The fact that the gravel is 
flattened and oblong in shape as a rule, the presence of lignite 
in different strata and of river sand in others, would go to 
confirm this theory, although the broken and disrupted charac- 
ter of the mountains back is an evidence of after disturbance. 
I present a fossil vertebra, obtained from the bank men- 
tioned, which may throw some light on the subject. Whatever 
may have been the origin of these deposits, and I do not pro- 
fess from lack of experience to form a definite opinion, 1t 1s 
certain that they offer an inviting field for the geologist and 
will some day demand careful study. 
After the completion of this paper, I received a letter from 
Prof. J. D. Dana, to whom I had sent specimens of the sands 
of Gold Bluff, from which I extract the following remarks : 
“The red grains in the sand are garnet. It is altogether 
probable that the deposit dates partly from the close of the 
Glacial era; that is, the time of melting of the ice in the early 
part of the Champlain period, when floods and gravel-depost- 
tion were the order of the day, and partly from the later part of 
the Champlain period, when the floods were but partially 
i ? 
abated, yet the depositions were more quiet.’

May 15, 1873.—Several shocks of earthquake were felt at 
Vaiparaiso, Chile. They commenced at 12.82 p. M. and lasted 
forty-two seconds. The motion was vertical. Several persons 
were hurt and killed; the Church of the Apostles was injured 
and the Merced was left in a dangerous state. Many other pub- 
lic and private buildings were more or less damaged. Severe 
shocks were also felt at Quillota and Santiago and slight shocks 
at various places as far south as Concepcion. 2 : 
June 29, 1873.—Severe shocks were felt at 5 a. M. in Venice 
and Verona, Italy, and the country north of those cities. sia? 
shocks were most violent about Belluno, fifty miles north 0 
Venice. Here several persons were killed and a church towe? 
was thrown down. In all, twenty-four deaths are reported, a 
a large amount of rty was destroyed. Mr. W. Star 
writes from Venice to the London Times, as follows: ‘There 
were fourteen movements in all, seven forward and seven bac i 
ward, and each movement occupied a second, as regular a0
