TraiiKportafioii. — In the 'Transactions of the Nova Scf)tian Institute of 

 Natural Science,' 1881-2, and in the 'Canadian Science .Monthly,' .Inly number, 

 the author has fjiven a list of nearly nil tlie accumulations of '(Hacial l)rift' that 

 lie has examined in and around Halifax Harbour. The following, however, have 

 been re-examined recently: — 



1, ThruUi-Ca]) and the beach which connects it with .McXah's Island, Th& 

 boulders in the drift were: ( 1 ) liuulders of Amygdnloidal rocks with Zfolites, which 

 were transported from lilomidon, and Syenites, Syi^nitic gneisses, Diorites, ^c. ; 

 from the Archrean rocks of the Cobeipiid .Mountains was observed also a great 

 mass of quartzite grooved and striated in a striking manner, an obvious part of the 

 machine Avhich ])loughed the rocks of IVjint IMeasant. On the beach, oesides the- 

 abundant quartzite bouhlers, were boidders of common basalt, basalt with olivine 

 and amygdaloids from lilomidon. (!') (iranites, micaceous, normal, and horn- 

 blendic ; Syenites, hornljlendie ; ( ineisses, with magnetite ; Diorites, with magnetite, 

 and Porphyrites from the ("obequid Blount ains. (.j) Sandstones from the carboni- 

 ferous formation of Hants and Colchester counties. 



:.'. In the drift at Point Pleasant were foun<i a line amygdaloid boulder of large 

 size with plenty of smaller ones, and Archiran boulders, .\notner large mass of 

 quartzite, strikingly grooved and furrowed, was also found. 'J'his aceumulation is 

 almost in a line with the Prince of Wales' Tower. 



.'). On Navy Island in 15edford IJasin, eight and a half miles above Thrum-Cap, 

 were collected (l) basalts, common ami chrysolitic, amygdaloiils. (2) Syenites, 

 Diorites with magnetite, hornblendic gneisses, Sic. 



4. On the opposite side were coUected (I) common linsalt and basalt replete 

 with large crystals of olivine and amygdaloids. (2) 11 arnbleiidic gneis.ses with, 

 magnetite. 



5. Not far from the ttqi of the liasin on the same side with Xavy Island, an<l 

 two miles above it, were collected from the drift, basalt, hornblendic gneiss witli 

 magnetite, porjdiyrites, &c. 



The Arcluean boulders of these accumulations have not come from the 

 Cobequid Mountains to the Halifax Harbour over the same course as the 

 Blomidon (triassic) boulders. They are a portion of the transportation which 

 had a sub-parallel course, which had been diverted from the general course S. 40"^ E.. 

 toS. nsis seen by the glaciation at Wellington Station, Intercolonial Railway. It 

 couse(iuently encountered the triassic transportation liefore it reachcu the harbour. 

 The united freight was carried along the harbour to the Atlantic and discharged at 

 Tiirum-t'ap or beyond, and then when the glacier retreated, McNab's Island, Point 

 Pleasant, Ueorge's Island, Navy Island, and other accumulations, were discharged 

 in succession. Thrum-Cap is the ultima thule of the great S.E. glacial transporta- 

 tion of Eastern Canada. 



i. Gleanings fro7ii Outcrops of Silnrlan Strata in Red lliccrValley^ Manitoba^ 



By J. HoYKS Panton, M.A. 



The country nortli of Winnipeg is apparently a very level prairie, but there are 

 several places where Silurian beds crop out— sometimes from beneath the drift ou 

 the banks of the Red River and Cook's Creek ; sometimes as rocks projecting 

 above the prairie level. The beds exposed are Limestones, which are worked for 

 ornamental and other purposes. 



There are four localities on the river banks, sixteen to twenty-one miles north- 

 east of Winnipeg, which the autlior groups together as yielding much the same 

 fauua; these are' between St. Andrews (North) and East Selkirk. The fossils
