erratic blocks and scored and planed surfaces ^o, it might have 

 taken place only a few years ago ; in some places where the peaty 

 material can be stripped off' the abraded surfaces, the face of the 

 rock is as fresh-looking as though the work had been done but 

 yesterday. I do not consider this glaciation could have been 

 older than of tertiary date, and it may very well be recent in age. 



Glacial Conglomerate. 



Quite distinct in character from the above, and differing 

 entirely in age, origin, and method of deposit, is a remarkable 

 conglomerate that occurs on the south side of the track between 

 Mt. Reid and Moore's Pimple, and about equidistant from each ; 

 the site is marked by a shallow hole, and it is 3,000 feet above 

 sea level, high above the observed morainal deposits, etc. The 

 conglomerate consists of a great variety of sandstones, igneous 

 rocks, shales, etc., nearly all well rounded and also beautifully 

 striated ; the pebbles and boulders are of non-local origin, unlike 

 the morainal matter above described, and it rests upon Devonian 

 sandstones. There is a marked similarity in the nature of the 

 cementing material, and in the character of the embedded pebbles 

 and boulders, to the glacial conglomerate found at Wild Duck 

 Creek, Victoria, and to the Dwyka congolmerate of South 

 Africa, and they probably all belong to a very ancient 

 epoch, either near the close of the Palaeozoic period, or else the 

 commencement of the secondary era. This particular outcrop is, 

 apparently, of no great thickness, and not very extensive, 

 but further search should discover more such outcrops, and their 

 relations might eventually be determined as regards the older 

 Devonian series, and also the more recently accumulated rocks.
