In reference to the Czech language we must also differ with you. Your argument that you have friends who speak the language does not strike us as very sound. There are numbers of Europeans who have learned Chinese, but that does not alter the fact that Chinese is an abnormally difficult tongue. If you will read our article through again you will see that your zeal for the Bohemians has made you defend them before they were accused. We stated that the governing of Austria is a very difficult task in consequence of the three conflicting elements of which it is composed, and explained the nature and grievance of each element. You must not let your sympathies cloud your judgment. EDITOR. INVENTION AND DISCOVERY. By means of slot-boxes one may buy gum or postage-stamps, be weighed, or have his picture taken. A schoolboy of St. Louis has recently invented a new and practical form of this popular machine. The Martin paper slot-box is to be used upon street cars and railway trains for the sale of daily papers. It has separate compartments for each morning daily, with movable name-slips so that the one box may serve for the sale of both morning and evening papers. Though small and neat, the box will hold forty-five papers. By inserting a penny and pushing a button, any paper desired may be had. The boxes are so arranged that five cents will be necessary to work the button for Sunday papers. The patent papers have been received, and the youthful inventor is superintending the making of the boxes. As soon as a sufficient number are ready they are to be given a thorough trial on the leading lines of cars in St. Louis.
