Having laid in a good stock of provisions, Mr. Low secured some stout cedar canoes, and set off on his journey from Lake St. John—he and the Indians. They did not advance with the speed which readers of Fenimore Cooper’s novels would expect. Their rate of progress averaged fifteen miles a day, the responsibility for this dilatoriness lying wholly with the Ashwapmuchuan River. Only every now and then is it a level, composed, and Thames-like avenue of water. In between whiles, after the wont of Canadian rivers, it plays leap-frog down the gradients. On approaching foaming rapids and roaring cascades, Mr. Low and the Indians got out and walked. Carrying canoes, stores, and baggage over portages that are sometimes a mile in length is, of course, a laborious and slow business. On the other hand, it is better to go through with that ordeal than to be whirled over a waterfall that has a sheer drop of sixty feet—to mention one picturesque feature occurring along Mr. Low’s route. I will not dilate upon the glorious mountains and the verdant valleys that came under the explorer’s notice. The lovely lakes—some of them twenty miles and more in length—rather tried his patience. “Many of them are so indented and dotted with islands,” he deplored, “that it is difficult for even the Indian guides to follow correctly the channels.” He noted the millions of dormant dollars existing in the form of timber: the black spruce (most abundant of all), the fir, the banksian pine, the aspen and balsam poplars, the white birch, the cedar, and other useful sorts. “White spruce up to twenty-four inches in diameter are,” he reported, “in many places numerous enough to permit of profitable lumbering if any means existed for transport to the southern markets.” But discerning science did not confine itself to indicating the fortunes in forests that awaited human immigrants. It shed a passing tear over the timber wealth that had been already consumed by immigrants of another genus. “Larch formerly grew in abundance,” Mr. Low reported, “and often they exceeded the white spruce in size,” as was obvious from old trees still standing as skeletons. But about twelve years ago, it seems, those forests were destroyed by a visitation of the European larch saw-fly—that wasp without a waist whose caterpillars have a large appetite, twenty legs, and an interesting way of standing with the hind part of their bodies gracefully curled over their heads. So our European saw-fly was the guilty party, was he? One wonders how in the name of Christopher Columbus he got across.
