All who were fit to walk went in procession from the fort to the statue, singing penitential psalms and the Litany and celebrating Mass.
Some days after this religious service Cartier met the interpreter, Domagaya, and to his surprise found him perfectly well and strong.

He asked him for an explanation, and was told that the medicine which cured this disease was made from the leaves and bark of a tree called ameda.[9] Cartier then ventured to say that one of his servants was sick of this unknown disease, and Domagaya sent for two women, who taught the French people how to make an extract from the balsam fir for drinking, and how to apply the same liquid to the inflamed skin.
The effect on the crews was miraculous.

In six days all the sick were well and strong.
[Footnote 9: This tree was the balsam fir, _Abies balsamea_.] Then came the sudden spring.

Between April 15th and May 1st the ice on the river was all melted, and on the 6th May, 1536, Cartier started from the vicinity of Quebec to return to France.

But before leaving he had managed to kidnap Donnacona, the chief of the Huron settlement, and six or seven other Amerindians, amongst them Tainyoanyi, one of the two interpreters who had already been to France.
