able height, as much as thirty-two feet at springs in some places, and in their fluctuations create tide-races, which have to be taken into consideration and carefully allowed for. Thus at the entrance to Churchill there is a tide-race, the velocity of which was estimated to be not less than seven knots.
In the matter of weather, Hudson Strait would seem to compare very favorably with that great highway of commerce, the Strait of Belle Isle, as the following table, which is for the month of August, clearly indicates:
| Belle Isle Strait. |
Hudson Strait. | |
| Number of days on which fog is recorded | 13 | 9 |
| Approximate number of hours of fog | 220 | 102 |
| Days on which snow fell | 0 | 4 |
| Days on which rain fell | 10 | 8 |
| Days on which wind exceeded twenty-five miles per hour, but did not reach forty | 6 | 5 |
| Days on which wind exceeded forty miles | 2 | 1 |
This is a very favorable showing for Hudson Strait, and it is strengthened by the annexed table, affording a comparison between Station No. 1 at Cape Chudleigh and Belle Isle. This table covers the month of September:
| Belle Isle Strait. |
Hudson Strait. | |
| Number of days on which fog is recorded | 7 | 4 |
| Approximate number of hours of fog | 82 | 34 |
| Days on which snow fell | 3 | 8 |
| Days on which rain fell | 15 | 6 |
| Days on which velocity of wind was between twenty-five and forty miles per hour | 4 | 5 |
| Days on which velocity of wind was forty miles or over per hour | 11 | 3 |
So far as weather is concerned, therefore, Hudson Strait enjoys a decided advantage over Belle Isle Strait, and on that ground, at all events, presents no difficulties of such a character that they can not readily be overcome by experienced, careful navigators.
Those portions of Lieutenant Gordon's report which deal with the resources and trade of the region he visited, interesting and important as they are, must be passed over for the present, while we hasten on to what he has to say concerning its natural history. Before doing so, however, it is worth noting that, although Hudson Bay belongs to Canada, its whale and walrus fisheries have been hitherto enjoyed by the Americans altogether, and the fur-trade has been entirely monopolized by the Hudson Bay Company, so that the Dominion practically obtains no benefit from these vast possessions whatever. Lieutenant Gordon accordingly, very properly, presses upon the Government of Canada the necessity of their turning their attention to this unaccount-
