The History of the Several Towns, Manors, and Patents of the County of Westchester (1881 revised edition, Vol. I)
The ministry of England wished to keep the command of New York in the hands of Mr. de Lancey but it was then, as it is to this day, a rule of the English Government never to appoint a native colonist to the supreme command over his own colony. To effect their object in this case without violating their rule, they decided not to appoint any new Governor as long as Mr. de Lancey lived ; he therefore remained the Governor of New York until his death, some three years afterwards, on the 30th of July, 1760."
"On the 19th of June, 1754, Governor de Lancey convened and presided over celebrated Congress of Albany, the first Congress ever held in America, over which he presided. This was a Congress of delegates from all the colonies, which the home government directed the Governor of New York to hold, for the purpose of conciliating the Indian nations who were invited to attend it ; of renewing the covenant chain and attaching them more closely to the British interest, and comprising all the provinces in one general treaty to be made with them in the King's name, and for no other purpose.6 Speeches and presents were made to the Indians who promised to do all that was asked of them, but no formal treaty whatever was concluded. The Congress voted instead, that the delegation from each colony except New York, should appoint one of their number, who together should be a committee to digest a plan for a general union of all the colonies.
