142 FIFTY YEARS IN WESTERN CANADA gathered was co-ordinated between points whose latitude had been duly determined, and thus it was that Father Morice obviated the necessity of a sextant. It can readily be realized that, in the course of twenty-one or twenty-two years’ explorations, the results of the missionary’s operations were consider- able. He ascended to the very source of the Black- water River and crossed the divide which separates its valley from the basin of the Pacific. He explored and mapped the important Nechaco River from its very mouth to its triple headwaters, namely, Lakes Morice, in the south, Dawson just north of it and Emerald still farther north. He likewise travelled over the Stuart River from mouth to source with inter- vening lakes (Stuart, Tremblay and Tatla) up to the Driftwood River, which, with the Tache and the Middle Rivers, form but one fluvial artery. He furthermore explored the Bulkley to its source in Loring Lake. That swift mountain stream had previously been called Morice in its upper reaches by a man who never was but many miles from the point where it receives the real Morice, a humble forest stream which is twice crossed by the telegraph trail.° He crossed by boat, on horseback or on foot, prac- tically the whole width of British Columbia, from the mouth of the Skeena up to Hazelton, thence to Babine, after that to Bear Lake on foot, and finally—always on foot—to Fort Grahame, within view of the Rockies and on the Finlay, which he then descended to the point where it receives the Parsnip. Going up this last river he reached the Pack, which he ascended up to Mc- Leod’s Lake. From this point he many times covered the eighty-five or ninety miles overland which separate 6 V. the end of next chapter.
