Saguenay
2 of the 6 encyclopedias on this shelf carry an entry for Saguenay. Both are reproduced below, so you can see where they agree and where they differ.
Collier's New Encyclopedia (1921)
a river of Canada, in the province of Quebec; formed by two outlets of Lake St. John, which unite about 9 miles below the lake, from which point the river flows S. E. and falls into the St. Lawrence at Tadousac harbor; length about 100 miles. For many miles of the latter part of its course the banks are very lofty, and in some parts there are precipices more than 1,000 feet high. Ships moor at rings fixed into some of the precipitous walls of rock, the water being so deep as to be unsuitable for anchorage. The Saguenay is navigable for vessels of any size to Ha Ha Bay, a distance of about 50 miles to 60 miles from the St. Lawrence, and at high water for vessels of large dimensions from 15 miles to 18 miles farther. It is visited by a great many tourists on account of its remarkable scenery.
Aiton's Encyclopedia (1910)
sag-e-na, a river of the province of Quebec. It enters the St. Lawrence through a deep canon at the Bay of Tadousac, 125 miles below Quebec. It drains Lake St. John. The greater part of its course lies between precipitous, rocky walls. As far as Ha-Ha Bay, at the foot of Chicoutimi Falls, the head of navigation, the channel has a remarkable depth of from 100 to 3,000 feet. The scenery is romantic and impressive. There is excellent salmon fishing. During the summer season, the Saguenay is visited by thousands of tourists. Steamers are taken usually at Montreal or Quebec. See Labrador
What Has Changed in the Last Century
Both accounts treat the Saguenay as a scenic tourist run — Aiton's in 1910 praises its "romantic and impressive" walls and "excellent salmon fishing," while Collier's in 1921 notes ships mooring to rings in the rock because the water is too deep to anchor. Within a few years the river became one of Canada's great industrial waterways: Alcan built the aluminium smelter and company town of Arvida in the mid-1920s, and the Shipshaw hydroelectric plant was completed during the Second World War to feed it. The old towns along the banks, Chicoutimi and Jonquière among them, were merged in 2002 into a single city called Saguenay, and a catastrophic flood in July 1996 destroyed hundreds of houses in the valley. The lower river and its beluga whales are now protected within the Saguenay–St. Lawrence Marine Park, established in 1998, and cruise ships call at Ha! Ha! Bay, which the encyclopedias knew as the head of navigation.
