10. WELLINGTON’s GALLERY is not attractive. 
11. Hese’s SprING is about four feet in diam- 
eter, and one foot. and a half in depth. Its 
water is charged with sulphuretted hydrogen. 
Twenty years ago, as we are informed by 
Dr. Wright, there was no sulphur in this 
Spring, and at the present time, when it has 
been undisturbed for several hours, pure water 
is found upon the surface, and sulphur water 
at the bottom, indicating the fact that it is 
supplied with sulphur water at the bottom and 
pure water near the surface which come from 
entirely different sources. 
Kyeless crawfish have been found in Hebe’s 
Spring. 
_ At the distance of half a mile beyond Hebe’s 
Spring, the Pass of El Ghor communicates 
with a body of water, the extent of which is 
unknown, called the Mystic River.
