There is reason to believe that the spot he had in mind to do this is the island which he had noted in his voyage of 1603, but to which he later gave the name of St. Helen.[23] This is most probable in view of his late marriage five months before with Hélène Boullé, for it could not have been given, as other names in the river had been, owing to the coincidence of a church feast day with the day of discovery, for Champlain arrived at Place Royale on the 28th of May and the feast of St. Helen fell on the 18th of August following, when he was in France. We know that Champlain had gone to the "Sault" in 1603, but he makes no mention of the site of Montreal in his account. However, with regard to the year of 1611, he gives us many interesting details. From these excerpts from the account of 1603 we may, therefore, sum up the following conclusions: (1) that (according to Laverdière) the place where Champlain "came to an anchor on the North Shoare over against one small island," was the little island formerly existing opposite the Place Royale (which was not, however, named till 1611) and now joined to the main land by the present harbour piers; (2) that incidentally he thus indicates the site of the present harbour of Montreal; that Champlain was the first to note that Montreal, or Hochelaga, was an island, this being deduced from his description of the great island (not named by him) "on the north side which continueth some fifteen leagues in length and almost as much in breadth," etc; (3) that the "mountain neere the said Sault which discovereth farre into the country" is the same as that named by Jacques Cartier as Mount Royal while "the Little River which falleth from the said mountain into the lake" is the Rivière des Prairies; (4) that while he gives no names beyond that of Sault yet he has left us a very clear indication that he was familiar with the site of the present Island of Montreal. From the above quotations there is no explicit mention of the suitability of the Island of Montreal as a future trading post, yet there is little doubt but that Champlain had it in his mind as such when the occasion should serve.
