In the spring of 1750, unable to obtain permission from Cornwallis to take a restricted oath, the Acadians almost unanimously decided to emigrate. On April 19 deputies from several settlements in the district of Minas--the river Canard, Grand Pre, and Pisiquid--appeared before the Council at Halifax and asked to be allowed to leave the province with their effects. [Footnote: Public Archives, Canada. Nova Scotia B, vol. iv, p. 130.] According to Cornwallis, they professed that this decision was taken against their inclination, and that the French had threatened them with destruction at the hands of the Indians if they remained. [Footnote: Public Archives, Canada. Nova Scotia A, vol. xxxvii, p. 7.] On May 25 the inhabitants of Annapolis Royal came with a like petition. In reply to these petitions Cornwallis reminded the inhabitants that the province was the country of their fathers, and that they should enjoy the product of their labours. As soon as there should be tranquillity he would give them permission to depart, if they wished to do so; but in the present circumstances passports could not be granted to any one. They could not be permitted to strengthen the hand of Great Britain's enemy. But in spite of the prohibition, of the forts that were built to enforce it, and of British cruisers patrolling the coasts to prevent intercourse with the French, there was a considerable emigration. A number of families crossed to Ile St Jean in the summer of 1750. They were aided by the missionaries, and supplied with vessels and arms by the French authorities at Louisbourg. By August 1750 we know that eight hundred Acadians were settled in Ile St Jean. CHAPTER VI THE 'ANCIENT BOUNDARIES' By the terms of the Treaty of Aix-la-Chapelle the question of the limits of Acadia had been referred to a commission of arbitration, and each of the powers had agreed to attempt no settlement on the debatable ground until such time as the decision of the commissioners should be made known. Each, however, continued to watch jealously over its own interests. The English persisted in their claim that the ancient boundaries included all the country north of the Bay of Fundy to the St Lawrence, and Cornwallis was directed to see to it that no subjects of the French king settled within these boundaries. The French, on the other hand, steadily asserted their ownership in all land north of a line drawn from Baie Verte to Chignecto Bay. The disputants, though openly at peace, glowered at each other. Hardly had Cornwallis brought his colonists ashore at Halifax, when La Galissoniere, the acting-governor of Canada, sent Boishebert, with a detachment of twenty men, to the river St John, to assert the French claim to that district; and when La Galissoniere went to France as a commissioner in the boundary dispute, his successor, La Jonquiere, dispatched a force under the Chevalier de la Corne to occupy the isthmus of Chignecto.
