In the spring and summer, a pull up the Don, while yet its banks were in their primeval state was something to be enjoyed. After passing certain potasheries and distilleries that at an early period were erected a short distance northward of the bridge, the meadow land at the base of the hills began to widen out; and numerous elm trees, very lofty, with gracefully-drooping branches, made their appearance, with other very handsome trees, as the lime or basswood, and the sycamore or button-wood.--At a very early period, we have been assured that brigades of North-west Company boats, _en route_ to Lake Huron, used to make their way up the Don as far as the "Forks," by one of which they then passed westward towards the track now known as Yonge-street: they there were taken ashore and carried on trucks to the Holland river. The help gained by utilizing this piece of water-way must have been slight, when the difficulties to be overcome high up the stream were taken into account. We have conversed with an early inhabitant who, at a more recent period, had seen the North-west Company's boats drawn on trucks by oxen up the line of modern Yonge-street, but, in his day, starting, mounted in this manner, from the edge of the bay. In both cases they were shifted across from the Lake into the harbour at the "Carrying-place"--the narrow neck or isthmus a little to the west of the mouth of the Don proper, where the lake has now made a passage. We add one more of the spectacles which, in the olden time, gave animation to the scene before us. Along the winding stream, where in winter the sleighs were to be seen coming down, every summer at night would be observed a succession of moving lights, each repeated in the dark water below. These were the iron cressets, filled with unctuous pine knots all ablaze, suspended from short poles at the bows of the fishermen's skiffs, out in quest of salmon and such other large fish as might be deemed worth a thrust of the long-handled, sharply-barbed trident used in such operations. Before the establishment of mills and factories, many hundreds of salmon were annually taken in the Don, as in all the other streams emptying into Lake Ontario. We have ourselves been out on a night-fishing excursion on the Don, when in the course of an hour some twenty heavy salmon were speared; and we have a distinct recollection of the conspicuous appearance of the great fish, as seen by the aid of the blazing "jack" at the bow, nozzling about at the bottom of the stream. _2.--From Tyler's to the Big Bend._
