do so, and said that I might add that the ordinary waste in harvesting wheat in Virginia, through the carelessness of the negroes, beyond that which occurs in the hands of ordinary Northern labourers, is equal in value to what a Northern farmer would often consider a satisfactory profit on his crop. He also wished me to say that it was his deliberate opinion, formed not without much and accurate observation, that four Virginia slaves do not, when engaged in ordinary agricultural operations, accomplish as much, on an average, as one ordinary free farm labourer in New Jersey.
Mr. Griscom is well known at Petersburg as a man remarkable for accuracy and preciseness; and no man's judgment on this subject could be entitled to more respect.
Another man, who had superintended labour of the same character at the North and in Virginia, whom I questioned closely, agreed entirely with Mr. Griscom, believing that four negroes had to be supported on every farm in the State to accomplish the same work which was ordinarily done by one free labourer in New York.
A clergyman from Connecticut, who had resided for many years in Virginia, told me that what a slave expected to spend a day upon, a Northern labourer would, he was confident, usually accomplish by eleven o'clock in the morning.
In a letter on this subject, most of the facts given in which have been already narrated in this volume, written from Virginia to the New York Times, I expressed the conviction that, at the most, not more than one-half as much labour was ordinarily accomplished in Virginia by a certain number of slaves, in a given time, as by an equal number of free labourers in New York. The publication of this letter induced a number of persons to make public the conclusions of their own experience or observations on this subject. So far as I know, these, in every case, sustained my conclusions, or, if any doubt
