TABULATION AND DESCRIPTION OF NEW DATA ^27 



A. P. Low has given (20, page 310) an elevation of 180 feet for the 

 high beach at Kachvack Bay. Evidently Low did not find the summit 

 level, and the figures of A. S. Packard, 200 feet for the highest beach 

 of the coast, are also beneath the Summit (24, page 310). But Low's 

 beach elevations for the coast of Hudson Strait (22, page 47 L), 405 

 feet, are in good accordance and are used for the 400-foot isobase of that 

 coast. 



Of these beaches he said : 



"The terraces at Dyke Head lie in a small valley at the bottom of a cove 

 facing the strait, and afforded one of the best examples of terraced beaches 

 seen on the coast, the heights being 405, 330, 275, 255, 220, 175, 90, and 85 feet.'" 



His figures for Ungava Bay, 300 to 325 feet, must be of inferior water 

 levels. 



For the Hudson Bay coast the only available figures are those of Low. 

 His* description of the successive levels in the district of Eichmond Gulf 

 (21, page 41 L) seem accurate and discriminating, and his reiterated 

 statement (22, page 46 L; 23, page 81 D) that the marine summit is 

 700 feet or over is relied on for the position of the isobase of that value. 



In his papers on the wide region west of Hudson Bay, J. B. Tyrrell 

 has noted high-level beaches which he discriminates from those of Lake 

 Agassiz and of other glacial waters (30, 33). He found beaches which 

 he regarded as marine up to 490 feet near Doobawnt Ijake, northwest 

 of Hudson Bay; and up to 600 feet south of Nelson River, between Lake 

 Winnepeg and Hudson Bay (30, pages 190-193 F). It appears probable 

 that the ice displaced the shallow waters of Hudson Bay, and that the 

 isobases should lie across the bay, but the present information is too 

 meager to justify the westward projection over that area. 



For Newfoundland it seems necessary to recognize an independent area 

 of glaciation and uplift amounting to at least 600 feet. The observa- 

 tions of Daly and others are for the coast, but the interior of the island, 

 where the ice-burden was greater, must have suffered more movement. 

 In a personal communication Professor Daly expresses confidence in the 

 practical accuracy of his figures for Cape Rouge Harbor, 505 feet, and 

 Kirpon Island, 450 feet plus ; but he hopes that the level at Saint John, 

 which he estimated at about 575 feet, may be more leisurely and precisely 

 measured (39, pages 257-259). 



Besides the figures by Daly on the northeast coast, we have some sug- 

 gestive ones by Tyrrell on the west coast. Writing of a. visit to New- 

 foundland during the summer of 1917, he says: 



"In Newfoundland the last glaciation, which was very strong, waKS from the 

 center outward both eastward and westward. If the glacier from Labrador
