granite (collected for another purpose) , and likewise a piece of the 

 Utopia ledge (secured for comparison with the medallion), and 

 knowing that a formation rarely remains entirely uniform for so 

 great a. distance, I thought that an expert comparison of the afore- 

 mentioned two specimens with the medallion stone might settle 

 whether or not the latter was obtained on the Island or at the Lake. 

 I was able to secure a fragment of the medallion from a partly loose 

 flake on the back, and I sent all three specimens to the Directing 

 Geologist, Mr. (now Dr.) William Mclnnes, of the Geological Survey 

 of Canada, with a statement of the interest of the problem, and a 

 request for an opinion on the relationship of the specimens from the 

 experts of the Survey. Under date October 30, 1915, Dr. Mclnnes, 

 to whom I am greatly indebted for this understanding aid, reported 

 as follows: 



In reference to the specimens: IM, from the back of a stone medallion; 2U, 

 from a ledge at Lake Utopia, and 3D, from Dochet Island; submitted for an opinion 

 regarding the identity of IM with either of the other two; there are no sufficiently 

 marked differences observable in these specimens to allow their being separated 

 with any certainty. 



VVe have had thin sections made from the specimens and I am glad to be able 

 to send you a memorandum by Dr. W. H. Collins in reference to them. 



"Memorandum in reference to thin sections of granites from specimens sub- 

 mitted by Dr. W. F. Ganong, by W. H. Collins. 



Thin sections marked IM, 2U, and 3D. 



All three are biotite granites much alike in composition and might easily 



belong to the same mass. 



i Section 2U is somewhat fresher than the others and contains notablj' more 



biotite and titaniferous magnetite. If a distinction is to be made, I should 



say that IM and 3D are probably the same, and different from 2U." 



Thus it developes that the medallion granite is nearly if not 

 quite identical with that of both Utopia and Dochet, with a balance 

 in favour of Dochet. This unimpeachable testimony, accordingly, 

 is wholly favourable to the possibility that the original stone slab 

 was obtained on the Island, which fact fits naturally with the sup- 

 position that it was carved there. Incidentally,, this identity of the 

 medallion granite with that of the Utopia-Dochet belt practically 

 settlers any question that the medallion is local work, and not brought 

 from a distance. 



The question is now natural whether the St. Croix colony is 

 known to have included any persons of sufficient skill, provided 

 with adequate tools, to carve the stone. This would be probable 

 from the character of the expedition, but is also attested by direct 

 evidence, for Lescarbot, who knew the colony intimately, states
