The colony required slave owners who wanted to free their slaves to pay a tax of £200 per person, then an amount much higher than the cost of a slave. In 1715 Governor Robert Hunter argued in London before the Lords of Trade that manumission and the chance for a slave to inherit part of a master's wealth was important to maintain in New York. He said that this was a proper reward for a slave who had helped a master earn a lifetime's fortune, and that it could keep the slave from descending into despair.
