182 Mr. Forster on Earthquakes-—Salisbury. 
In giving the Newark system a specific name all expression 
of relationships with other terranes in this country implied in 
the names heretofore in common use, is avoided. Certain por¬ 
tions of this system may be more or less definitely correlated 
with portions of the Red Beds of the Rocky Mountain region, 
but to say that the Newark system as a whole is synchronous 
with the Red Beds, or with the Red Beds and the intimately as¬ 
sociated Jurassic rocks, is to carry inference far in advance of 
observation. 
I also claim an absolute divorce of the rocks of the Newark 
system from the copper-bearing rocks of Lake Superior, and 
from the red sandstone of Maine and New Brunswick with 
which they have sometimes been correlated. Whether the rocks 
just referred to are closely related in age to the Newark system 
or not is immaterial at present, as they are mentioned simply 
as examples of what is not included under the name here pro¬ 
posed. 
MR. FORSTER ON EARTHQUAKES* 
By R. D. Salisbury. 
Somewhat more than a year ago Mr. W. G. Forster, manager 
and electrician to the Eastern Telegraph Company, Zante, is¬ 
sued a somewhat lengthy paper (68 pp.) on Seismology, which 
seems not to have attracted that attention to which it is entitled. 
Some of the foreign periodicals spoke slightingly of the paper, 
though failing, at the same time, to give an adequate idea of its 
contents. This was perhaps not to be wondered at, since that 
portion of the paper which is of especial interest—the record of 
Mr. Forsters own observations—is prefaced by a lengthy dis¬ 
cussion concerning the theory of earthquakes, which seems not 
to have found much favor, and which has perhaps deterred re¬ 
viewers from a complete perusal of the paper. The facts which 
Mr. Forster records, are however, of so much importance, that 
it seems fitting to give them wide circulation through the 
columns of an American journal. 
Located in the midst of a region where seismic disturbances 
are frequent and often severe, and holding an official position
