of ice from the Cradle Mountain and Barn Bluff have flowed 

 clown and eroded the gorges of the Mackintosh and Murehison 

 Eivers and their tributaries, -which at the present time drain 

 these high altitudes, than travelled over their deep-cut gorges 

 a distance of forty miles, to the high land around the peat of 

 Mount Sedgwick'? and to substantiate this Mr. Montgomery 

 savs " there are grounds to believe that the Valley of the 

 Mackintosh has been scoured out by glacial action." _ I now 

 hope Mr. Montgomery will accept this theory, and eliminate 

 all possibility of the conglomerate having been formed at the 

 later period, for the only proof of such ice action is not con- 

 fined to a region where there has been evidently severe glacia- 

 tion at a much later date. 



In the beginning of April this year (1894), while gravelling 

 from Zeehan to my old friend Sprent's top crossing of the 

 Pieman Eiver, I came across an extensive bed of a similar 

 glacial conglomerate to that at Mounts Bead and Sedgwick 

 lying in a low basin-shaped valley about four miles north 

 from the town of Zeehan, and west of the horse track leading 

 to the punt placed on the Pieman Eiver for the use of the 

 Stanley Eiver tin miners. 



The bed, as near as I can approximate^ estimate, is about 

 a mile long by a quarter of a mile wide, and appears of no 

 great depth. I picked up numerous scored pebbles, but in 

 the limited time at my disposal did not obtain any carbon- 

 iferous tossik. Yet I feel positive they are to be found, for 

 the rocks composing the conglomerate and the binding 

 material are identical with those of the former discoveries of 

 Mr. Dunn and myself. 



The height of this bed is between three and four hundred 

 feet above sea level, and if not formed by the agency of 

 floating ice in the Permo-carboniferous age, Mr. Montgomery 

 must allow that the recent glaciers have descended to a much 

 lower level than he anticipated. Finding this extensive 

 deposit at such a low altitude, far from any proofs of recent 

 glacial action, and precisely similar to the other more elevated 

 conglomerates at Mounts Eead and Sedgwick, it is only 

 reasonable to suppose that all belong to the same glacial age 

 and method of deposit, as Mr. Johnston describes it, the 

 ancient glacial epoch of Permo-carboniferous age. 



In these notes I regret to have to dispute the theories of 

 much abler men in the scientific world than myself, but what 

 information I have gathered is from actual observation, and 

 my records only embrace indisputable proofs of glacial action, 

 which I trust will throw more light on the true aspect of this 

 interesting subject. 



In the beginning of July last year (1893) I had occasion to 

 visit the western base of the Craycroft Hills, east of Mac- 

 quarie Harbour ; here I found a huge terminal moraine,
