He undid the side door, and the policeman, very cautiously, came in. And there, in the kitchen, by the light of one candle, with the mewing and the screaming going on like a dozen steam sirens, twenty waiting motor-cars, and half a hundred squeaking pumps, four agitated voices shouted to the policeman four mixed or wholly different explanations of the very mixed events of the evening. Did you ever try to explain the simplest thing to a policeman? _Curiosities._ Copyright, 1904, by George Newnes, Ltd.

[Illustration] "There is a blacksmith's shop at Llancayo, near Usk, Mon., that possesses an extraordinary window. The framework of the window consists of a cart-wheel let into the wall, with panes of glass between the spokes."--Mr. W. Marsh, 1, Church Street, Monmouth. CURIOUS ADDRESS. "I send you a post-card which I received in the ordinary way by post from my brother, who lives at Sutton Scarsdale, a scattered village near Chesterfield. You will notice that the card was posted at 7.15 p.m. on the 5th October, and it was delivered during the evening of the following day. The address looks a mixture of Greek and German, but on inspection it will be found that each letter is spelled out in full. The pencilled words were inserted by the Post Office officials. The Post Office is often the object of complaints for tardiness in delivery, but I think great credit is due to it for its cleverness and promptness in this case."--Mr. John Alderson, 12, Albert Road, Stroud Green, N. [Illustration] A DISTORTING MIRROR. "While staying in Jersey I visited a point called La Corbière, where I noticed a mirror in the form of a ball standing out in the open on a pedestal. Objects reflected in it were so clear that I determined to photograph it, with the result that rather curious shapes were given to myself and friend." Mr. C. S. Wilson, 18, Milton Road, Swindon. [Illustration] HOME-MADE MOTOR-CAR. [Illustration] "This original auto was made in the winter of 1886 by Mr. Philbrick and Mr. J. Elmer Wood in Beverley, Mass. It had double engines, porcupine boiler, kerosene fuel, and only three wheels--two of which were thirty-six inches in diameter, and the front, or steering-wheel, twenty-six inches. It was used on the road with great success, carrying about three hundred pounds of steam, but wanted some changes, which even at that early date we could easily see. The machine is still existing at Beverley, though it is now, of course, somewhat dilapidated after so many years of wear."--Mr. J. Elmer Wood, Beverley, Mass. AN AUTOMATIC BASEBALL PITCHER.
