There is, in the case of such partially explored regions, more excuse for the delineation of the main features on our maps, as these may be useful in imparting general information of a more or less inexact kind. We can scarcely, however, admit that such regions have been explored in any true sense of that term, while they are certainly unsurveyed, and very little confidence can be placed in maps of this kind as guides in travel. When, ten years ago, I struck across from Fort Macleod, on the west side of the Rocky Mountains, with the purpose of reaching Fort Dunvegan on the Peace, through a country densely forested and without trails or tracks of any kind, I had so much confidence in the existing maps of that region as to assume that Dunvegan was at least approximately correct in position on them. As often as possible I took observations for latitude, and each night worked out our position by latitude and departure, till at a certain point I was about to turn off to the north of the line previously followed with the confident anticipation of finding Dunvegan. Just here, very fortunately, we fell in with some Indians, and though our means of communicating with them were very imperfect, we gathered enough to lead us to accept the guidance of one of them, who promised to lead us to the fort, but took an entirely different direction from that I had proposed taking. He was right, but Dunvegan proved to be, as shown on the maps, nearly forty miles west of its real position. Fortunately no very great importance attached to our reaching Dunvegan on a given day, but none the less, this practical experience proved to me very conclusively the desirability of showing features in broken lines, or otherwise indicating their uncertainty when they have not been properly fixed.
It must be confessed, however, that most of the travellers ordinarily to be found in these unexplored regions, being Indians or hunters, traders and others travelling under the guidance of Indians, do not depend on the latitudes and longitudes of places, or on the respective bearings of one place from another. The Indians follow routes with which they have been familiar since childhood, or, when beyond the boundaries of their own particular region of country, go by landmarks, such as mountains, lakes, and rivers, which have been described to them by their neighbours. Their memory in this respect is remarkable; but it must be remembered that among their principal subjects of conversation when sitting about the camp-fire are the distances in day's journeys from place to place, the routes which they have followed or have known others to follow, the difficulties to be encountered on these, the points at which food of different kinds may be obtained, and the features which strike them as being remarkable in the country traversed. Returning, however, from this digression, which began with the statement that accurate maps of such regions as are at present merely traversed by traders and Indians, are not imperative from the point of view of such travellers, it may with confidence be affirmed that such maps and explorations upon which they are based are absolutely essential to civilized society, to show in the first place what the natural resources of these regions are and how they may be utilized, in the second by what highways such regions may be most easily reached.
A glance at the map will show, that while many of the larger unexplored areas may be affirmed to lie to the north of the limit of profitable agriculture, considerable regions situated to the south of this limit still await examination. Large districts, again, in which no farmer will ever voluntarily settle, may afford timber which the world will be glad to get when the white pine of our nearer forests shall become more nearly exhausted, while, with respect to mineral resources, it is probable that in the grand aggregate the value of those which exist in the unexplored regions will be found, area for area, to be equal to those of the known regions, comparing each particular geological formation with its nearest representative. On the grounds alone, therefore, of geographical knowledge, and of the discovery and definition of the reserves of the country in timber and minerals, the exploration of all these unknown or little-known regions may be amply justified.
Taking a line drawn north and south in the longitude of the Red River Valley, which is, as nearly as may be, the centre of Canada from east to west, it may confidently be stated that by far the larger part of the country in which agricultural settlement is possible lies to the west, while the great bulk of the actual population lies to the east of this line. Looking to this grand fundamental fact, I believe it may safely be affirmed that some members of this audience will live to see the day when these conditions with respect to population will be boldly reversed, and in which the greater number of our representatives in Parliament gathering here will come from this great western region.
This disposition of the cultivable land depends partly upon the physical characteristics of the country, and in part on its climatic conditions. Beyond Winnipeg, and stretching therefrom to the west and north-west, is the great area of prairie, plain, and plateau, which, wider near the forty-ninth parallel than elsewhere on the continent, runs on in one form or other, though with diminishing width, to the Arctic Ocean. This is, generally speaking, an alluvial region, and one of fertile soils. Very fortunately, and as though by a beneficent provision of nature, the climatic features favour the utilization of this belt. The summer isothermals, which carry with them the possibility of ripening crops, trend far to the north.
Let us trace, for example, and as a rough and ready index of the northern limit of practicable agriculture of any kind, that isothermal line which represents a mean temperature of 60° Fahrenheit in the month of July. Passing through the southern part of Newfoundland and touching the island of Anticosti, this line runs to the north end of Mistassini Lake, and thence crosses Hudson's Bay, striking the west shore a short distance north of York Factory. Thence it runs westward, skirting the north end of Reindeer Lake, and then bending to the north-west, crosses Great Slave Lake, and touches the southern extremity of Great Bear Lake. From this point it resumes a westward course and crosses the Yukon River a considerable distance to the north of the confluence of the Pelly and the Lewes, turning south again almost on the east line of Alaska. We need not, however, further follow its course, as owing to peculiar climatic conditions on the West Coast, it ceases there to be any criterion as to the conditions of agriculture.
The character of much of the western interior country is such that its exploration and survey is comparatively easy, and it will be observed that here the larger unknown regions are to be found only far to the northward, leaving in the more rugged and inhospitable eastern region vast islands of unexplored country in much more southern latitudes.
It may be said, in fact, that comparatively little of the region capable, so far as climate goes, of producing wheat is now altogether unknown; but it may be added, that increasing as the world now is in population, its people cannot much longer expect to find wheat-growing lands unoccupied in large blocks. The time is within measurable distance when lands with a fertile soil though more or less rigorous climate, in which only barley, oats, hemp, flax, and other hardy crops can be matured, will be in demand, and we are far from having acquired even a good general knowledge of these lands in Canada.
For many of the unexplored regions marked upon this map, however, we can in reason appeal only to their possible or presumable mineral wealth as an incentive to their exploration, and if some of them should prove wholly or in great part barren when such exploration shall have been carried out, it will not be without utility to acquire even this negative information, and write upon them in characters as large as need be, "No thoroughfare."
I will now ask your further attention for a few moments while I run over and make some remarks in detail on the various unexplored areas as indicated on the map. It must first, however, be explained in what manner the unexplored areas referred to have been outlined. All lines, such as those of rivers, chains of lakes, or other travelled routes, along which reasonably satisfactory explorations have been made and of which fairly accurate route-maps are in existence, are given an approximate average width of about fifty miles, or twenty-five miles on each side of the explorer's or surveyor's track. The known lines are thus arbitrarily assumed to be wide belts of explored country, and that which is referred to as unexplored comprises merely the intervening tracts. By this mode of definition the unexplored regions are reduced to minimum dimensions. Neither are any comparatively small tracts of country lying between explored routes included in my enumeration, in which the least area mentioned is one of 7500 square miles; nor are the Arctic islands, lying to the north of the continent, referred to. Because of the empirical mode in which the unexplored areas have thus been delineated, it has not been attempted to estimate with more than approximate accuracy the number of square miles contained in each, my purpose being merely to render apparent the great dimensions of these areas.
