and wherever a footprint is found over one of them it is a on 
either side, leaving the seam as too hard for the instrument. As yet I 
have never met with any footprints in the Western States, that have not

Oct. 26, and Nov 846.)—Mount Hecla is a very regular cone, 
with slopes of wees, eS to thirty degrees; covered with scoria an 
fragments. The height was determined by two observations at 1886°3, 
and 1396-8 metres, which is more than 160° metres less than Serther 
trigonometrical measurements. ‘The great current of 1845 flowed to 
the west-south-west ; the whole length is sixteen kilometers, (near ten 
miles,*) and greatest breadth two kilometers. It is found covering 
declivities of all angles, from 0° to 25°, and every where the surface 
consists of blocks, often of large size, accumulated with some regu- 
larity, and forming a broad band having the lateral slopes thirty-five to 
7 degrees. Over the surface there are numerous fumeroles, about 
no salts were observed excepting sal-ammoniac.

waters were at a temperature of 98° C. = 208° F. 
Experimenting on the great geyser, which is twenty-two metres in 
depth, this geologist found the rier: at one trial 121°°6 C., within
