Three quarters of a mile north there are a few pegmatite veins in theschist, and 100 yards beyond this contorted bands of schist are found entangled incoarse granite. At the next station, Cutler, on the north shore of Lake Huron, there are largemasses of quartzite showing stratification but greatly bent and folded and cut by dikesof granite and pegmatite. The quartzite must have been more nearly pure quartz than therock which formed the schists to the east, some of which look much like the westernCouchiching. A mile or two west of Cutler, near the flag station Kenabutoh, the sedi-ments have almost entirely foundered in the Laurentian magma forming a well bandedgneiss, but four miles west a large mass of schist in the typical Laurentian has onepart much metamorphosed, while another part still retains its stratification and evenpseudomorphs after staurolite. The original rock must have been Sudbur> (Juartzite and Schist, near Granite, Cutler At Serpent river the schists occur once more without granite, but toward the northare interrupted in places by greenstone or diorite. Two miles beyond there is graychloritic slate with the normal strike of 70° and a vertical dip. but half a mile to thewest this becomes more schistose and passes into green schist like certain Keewatinrocks of the west. This continues for a mile beyond Spragge, the next station, when itis followed by slate and quartzite or arkose containing pebbles of granite. The relationshere are uncertain, and it is possible that these rocks may be Huronian, since theyseem unlike the Sudbury series. The fact that they stand nearly vertical is, however,against placing them in the Huronian. Similar rocks of uncertain age, sometimes in-cluding gray and red slate and occasionally forming a conglomerate crowded withboulders of granite, extend to within a mile of Algoma. To th
