1873  (1904)  One night's delay, and again we were on the endless trail; on along the great silent river . . . amidst the great diamond-shaped islands where the snow lay deep and soft in "shnay" and "batture."
1896  (1898)  We continued through the winding chenals (anglicized as schnys), among low islands, where we ran uncomfortably close to sunken rocks.
1909  A narrow channel is called a "she-ny," evidently a corruption of the French chenal.
1961  . . . around Bryson and Campbell's Bay [Ottawa Valley] . . . one still hears the expression "The Shnye"--seemingly holding onto the "ch" of "chenal."
