reached in Paris in 1738, when the famous works of Vaucanson appeared. The Flute-Player (see cut) is the most celebrated of them all. It is said that the idea came to Vaucanson one day in the Garden of the Tuilleries while looking at the statue of a faun playing on a flute.

In the counties of Kent and Essex, in western Ontario, many farmers have abandoned sugar-beet raising to engage in the production of tobacco. Last year the crop was very profitable in this section, bringing the planters an average of $104 per acre. The average yield was 1,300 pounds to the acre, and the average price about 3 cents per pound. One farmer, on something less than six acres of land, raised a crop which sold

When President Roosevelt set foot on foreign soil at Colon, Isthmus of Panama, he broke another historic precedent. No other President ever left his native land during his term of office. Although his stay on the isthmus was so short, President Roosevelt made a careful first-hand investigation of the work under way, showing the same eager spirit and half-scornful disregard of personal comfort, which have distinguished him on so many other occasions. All along the canal zone he talked with the men, took a hand at running their machines, heard their complaints and suggestions, and inspired them with something of his own bubbling energy and enthusiasm. It is said to be his greatest ambition to go down into history as the President who built the Panama Canal.
