FOR some years past a rising tide of lecturers and literary men from England has washed upon the shores of our North American continent. The purpose of each one of them is to make a new discovery of America. They come over to us travelling in great simplicity, and they return in the ducal suite of the Aquitania. They carry away with them their impressions of America, and when they reach England they sell them. This export of impressions has now been going on so long that the balance of trade in impressions is all disturbed. There is no doubt that the Americans and Canadians have been too generous in this matter of giving away impressions. We emit them with the careless ease of a glow worm, and like the glow-worm ask for nothing in return.
