286 Chronicles of Science. | April, 
In our last we referred to the discoveries of silver said to have 
been made in California. We said we should watch the result with 
much interest, and we have reasons now for placing our readers on 
their guard. The reports of some English engimeers who have 
been sent out to examine the district are by no means satisfactory. 
For example, reports of the following description from Austin- 
Nevada are not encouraging :—“ We are on the eve of bad times; 
rascality and bad management have been doing their evil work; 
owners of ‘wild cat’ sold claims at high prices; hundreds of 
stamps will stand idle for months to come,” &., &e. One gentleman 
of eminence in his profession will shortly return to this country ; 
from him we may expect reliable information. In our next we 
hope indeed to furnish a report on the wonderful ‘ Silver-peak” and 
the adjoiing argentiferous district. 
The “ Comité des Houilleres Frangaises,” according to their annual 
custom, have just issued thei “Situation de l’Industrie Houillere 
en 1865.” From this publication we learn that the production of 
coal from the French collieries in all the Departments amounted to 
about ten millions and a-half English tons. The French received 
for consumption, in addition to their own produce, from 
Tons.

They also imported 651,930 tons of coke from these countries. 
The American government have lately published a very impor- 
tant volume, showing the industrial resources of the United States 
and their commercial relations with foreign countries. From this 
we extract the following information respecting the coal produce of 
Eastern Pennsylvania and the bituminous coal trade of Maryland.
