The next day, still sailing to the west, he reached so fine an anchorage that he was induced to land and plant a cross there in honour of St Servan.

Beyond this again was an island 'round like an oven.' Still farther on he found a great river, as he thought it, which came sweeping down from the highlands of the interior.
As the boats lay in the mouth of the river, there came bearing down upon them a great fishing ship which had sailed from the French port of La Rochelle, and was now seeking vainly for the anchorage of Brest.
Cartier's careful observations now bore fruit.

He and his men went in their small boats to the fishing ship and gave the information needed for the navigation of the coast.

The explorers still pressed on towards the west, till they reached a place which Cartier declared to be one of the finest harbours of the world, and which he called Jacques Cartier Harbour.

This is probably the water now known as Cumberland Harbour.
The forbidding aspect of the northern shore and the adverse winds induced Cartier to direct his course again towards the south, to the mainland, as he thought, but really to the island of Newfoundland; and so he now turned back with his boats to rejoin the ships.
