are bordered on either side by mountains one or two thousand 
feet high with their tops more or less covered with snow from 
which were flowing glaciers. I could count six extensive glaciers 
in sight above me at one time. In passing we had a favorable 
opportunity to examine the rocks for eyidence of a once existing 
Glacial Period, corresponding to that seen in the north, and Prof. 
Agassiz made: his observations with perfect satisfactory results. 
The mountains on both sides showed unmistakable evidence of a 
large glacial mass of ice once pushing its way south northwards. 
We stopped one afternoon at Glacier Bay to visit the grand glacier 
which is moving slowly down the valley from the snow on the 
mountains, the accumulations of winters, and from which the Bay 
‘Teceives its name. The glacier was at least four miles long, two 
hundred feet thick and one mile wide at the termination. The 
progress of the mass down the valley was ascertained to be three 
tighths of an inch per hour. All the necessary observations were 
carefully made by Prof. Agassiz. From the Sraits of Magellan 
We steamed inland up Smyth Channel and saw, for the first time, 
the Pacifie at the outlet of Gulf of Pénas. Touching at two 
ports on Chiloe Island we went to Lota for coal and arrived here 
on the afternoon of the 11th inst. ` We shall remain here several 
Weeks and there is a favorable prospect for our making a large 
collection of specimens. —J. Henry Braxe. U. S. O. S. Steamer,

We call attention to the card of Mr. Sanborn, the well known
