Grillet remained a month with his Protestant friends, Lord Willoughby coming occasionally to visit him. From Barbadoes he was conducted to Montserrat, where "Milord, after celebrating Christmas ten days later than we do," notes Grillet, "for the English did not accept the Gregorian Calendar," then handed him over to a Catholic colonel of a Yorkshire regiment, who finally delivered him safe and sound to the French Governor de la Barre. This was the de la Barre who was afterwards to figure in Canadian history. Grillet then returned to his old mission work at Cayenne, for the English had abandoned it, and with Father Béchamel set out to explore the interior, with a view to future missionary establishments. With no other provision than a little cassava bread, and no other escort than a negro and a few Indians, they began a journey of 1920 miles, through forests and swamps and across mountains and down rivers which were continually broken by cataracts merely to find where the Indians were living, so as to send them missionaries later. They had started from Cayenne on January 25, 1674, and returned there on June 27. Both died shortly after. Along both banks of the Oyapoch, throughout its whole course, missions were established by other valiant apostles who, as a French historian relates, had formed the gigantic project of uniting by a chain of stations both extremities of Guiana. Indeed, the church on the Kourou was only an incident in this work. Eleven years before that, Arnaud d'Ayma had fought his way to the Pirioux, the remotest of all the known tribes. There he lived like the savages in a miserable hut, spending every moment among them in studying their language and teaching them in turn the truths of salvation. He then founded a mission on the Oyapoch where he collected the entire tribe of the Caranes. Meantime, D'Ausillac looked after the Toeoyenes, the Maowrioux, and the Maraxones on the Ouanari. Up to the time when de Choiseul, minister of Louis XV, drove the Jesuits out of Guiana, one hundred and eleven of them had devoted their lives to the evangelization of that country.
