Further discoveries of glaciation, west coast, Tasmania

Through the courtesy of Messrs. E. J. Dunn, R. M. Johnston, and A. Morton I have received the two former gentlemen's and Mr. Montgomery's papers of last year on Glaciation.
First I shall make a few comments on these papers, then relate my own experiences since writing on this interesting and important subject.
Both Messrs. Johnston and Montgomery take exception to my giving Mr. Dunn the honour of being the discoverer of land glaciation in Tasmania. I was quite aware that evidences of boulders, etc., transported by floating ice had been discovered, and surmises made that land glaciation had existed, but I still think that Mr. Dunn was (to use Mr. Montgomery's own words) "the first to bring forward indisputable proofs" of prehistoric glaciers, and this was my meaning when I wrote last year.
With regard to former discoveries enumerated in Mr. Johnston's list of " Principal Sources of Reference," I might rank as one of the early discoverers of evidences, although not mentioned in this list. For in 1883 I visited Lake Dixon, and also passed over Painters Plains, and was struck by the number of scattered granite and greenstone boulders and large boulders of the latter rock resting on the summit of Artist Hill and other prominent heights ; also similar evidences all through the Collingwood Valley.
