chains in a direction N. 10° E. from the east side of the outlet. 

 The top of the moraine rises to a level of 6340 feet, about 160 

 feet above the surface of Lake Merewether. The exact depth of 

 the lake is not known, but it is thought by local residents to be 

 not less than 40 feet in its deepest part, in which case the 

 terminal moraine is probably about 200 feet in height. 



It is difficult, however, to draw the line (if any exists) between 

 this terminal moraine and the remarkable moraine now to be 

 described. If the spur to the west of the outlet of Lake Mere- 

 wether be ascended further to the west, it is found to lead up to 

 one of the most interesting glacial features in the whole Kosciusko 

 region, a wonderfully perfect mioraine, even more like a huge 

 railway embankment than the smaller one already described near 

 Townsend's Pass. This remarkable feature has already been 

 referred to by one of us (Mr. Helms) in an earlier paper (7, pp. 357- 

 358). 



This moraine is about 29 chains in length, measured along the 

 top of the ridge, its width at the top being uniformly about 16 

 yards. Its trend from its western end, where it abuts against 

 the junction line between the slate and granite, is first E. 5° S. 

 for 15 chains, then E. 7° S. for 14 chains. It is bounded on 

 either side by steep slopes, its summit is nearly level, and its 

 altitude is about 6,550 feet, that is just 400 feet above the level 

 of the surface of Lake Merewether. The whole amount, how- 

 ever, of the material between these levels is not moraine, as to 

 the S.W. of Lake Merewether the grooved granite surfaces can 

 be traced up to a level of 6,280 feet, where they disappear under 

 the moraine. The remainder, therefore, of the slope between 

 6,280 feet and 6,550 feet, in all a thickness of 270 feet, may be 

 looked upon as moraine, so far as the northern slope of the 

 moraine is concerned. 



As regards the southern slope, grooved surfaces of granite out- 

 crop the levels up to 6,330 feet, so that on this side the moraine 

 material may not be more than 220 feet in thickness. The 

 number of beautifully glaciated boulders in this moraine is 

 remarkable. A cart-load of such boulders could be collected 

 from the moraine by a couple of men in half an hour. The
