Things unknown in 1763.--Had a traveler landed on our shores in 1763 and made a journey through the English colonies in America, he would have seen a country utterly unlike the United States of today. The entire population, white man and black, freeman and slave, was not so great as that of New York or Philadelphia or Chicago in our time. If we were to write a list of all the things we now consider as real necessaries of daily life and mark off those unknown to the men of 1763, not one quarter would remain. No man in the country had ever seen a stove, or a furnace, or a friction match, or an envelope, or a piece of mineral coal. From the farmer we should have to take the reaper, the drill, the mowing machine, and every kind of improved rake and plow, and give him back the scythe, the cradle, and the flail.
