When you grow up you should join the Society, and then you would be able to do a great deal for animals. They will love you for your kind little heart as much as we do. You might do something to help your favorites now, by getting all the boys and girls you know to join you in forming Bands of Mercy. These are clubs of young people who pledge themselves to be kind and helpful to all animals. Write to Mr. J.L. Stevens, the Secretary of the American Humane Education Society, Milk Street, Boston. Tell him THE GREAT ROUND WORLD gave you his address, and he will send you information about forming your club, and about the badges and rules. You can do a great deal for suffering animals by interesting other boys and girls in the work, and teaching them that we ought to be even kinder to animals than we are to one another, because animals are dumb, and cannot tell us when they suffer. EDITOR. We have great pleasure in informing our readers that we are about to publish a volume of "GREAT ROUND WORLD Natural History Stories." We know how much our young friends love _true_ stories. This collection will contain only true stories, and has been written by one who was an intimate friend, as she says, of each of these interesting creatures. It has taken several years to collect them, and they are being prepared and illustrated with the greatest care. We publish one story as a supplement, and will be very glad if our readers will let us know if it pleases them. We are constantly having new books sent in to us. We would like to have our subscribers read the books, and write us what they think of them. Letters of this kind will be printed in THE GREAT ROUND WORLD from time to time. Any of our subscribers who have had a letter about some book published may become a "reader"--that is, new books will be given them to read, and write an account of. If the account is well-enough written to be published, the book may be kept; and others will be sent from time to time for criticism of this kind. INVENTION AND DISCOVERY. Some lover of the wheel, who evidently cannot bear to lose the pleasure of wheeling even when the snow lies thick on the ground, has invented a sleigh attachment. This is a runner fastened beneath the driving-wheel of the bicycle. [Illustration] What a great thing this will be! Fancy wheeling away over the snow, propelling our wheels as fast as the pedals can make us go. The bicyclists ought to be very happy this year; so many clever brains are working for their comfort and pleasure. [Illustration] All who ride have been troubled at times what to do with the bicycles when they are standing still. It may be there is damp grass, which would make it impossible to lay the precious wheel down; or there may be a thousand other little inconveniences.
