Slavery thereafter tended to expand. The Edict of October 1727 concerning the American islands and colonies and therefore including Canada in the preamble spoke of the islands and colonies being in a condition to support a considerable navigation and commerce by the consumption and trade of Negroes, goods and merchandise, and the measures taken to furnish the necessary Negroes, goods and merchandise. It was decreed that only such Negroes, goods, and merchandise should be received by the islands and colonies as should be brought in French bottoms. Very explicit and rigid regulations were made to that end.
Some of these slaves were too vindictive to be good servants. There is given by Abbé Gosselin in a paper in the _Transactions, Royal Society of Canada for 1900_, an account of a mutiny of part of the garrison at Niagara incited by a Panis probably in the service of an officer at the post. Some of the mutineers were sentenced to death but made their escape while the Panis, Charles, was sent to Martinique with a request to the authorities to make him a slave and to take every precaution that he should not escape to Canada or even to the English colonies. A female slave of color belonging to Mme. de Francheville who had been bought in the English Colonies set fire to her mistress' home the night of the 10-11 April 1734, thus causing a conflagration which destroyed a part of the city of Montreal. The unfortunate slave was apprehended and tried for the crime then and for long after a capital felony. Being found guilty, she was hanged June, 1734.
The increase in the number of slaves made necessary some regulation concerning their liberation. September 1, 1736, Gilles Hocquart, the Intendant already mentioned, made an ordinance concerning the formalities requisite in the enfranchisement of slaves. Reciting that he had been informed that certain persons in Canada had freed their slaves without any other formality than verbally giving them their liberty, and the necessity of fixing in an invariable manner the status of slaves who should be enfranchised, he ordered that for the future all enfranchisements should be by notarial act and that all other attempted enfranchisements should be null and void.
