DEAR READERS OF "ST. NICHOLAS:" I live in a city of iron and steel manufactories. I will do my best to tell you how an ax is made. The works are a beautiful sight at night, with their huge, glowing furnaces and the forms of the brawny workmen, passing between us and the light. In one furnace they are heating pieces of cast-iron, about twelve inches long, four inches wide, and one-half inch thick. A workman takes a pair of long pincers, draws from the furnace one of the red-hot pieces of iron, and passes it to another workman. This workman is standing before two large wheels, which revolve slowly, and which have several notches in them. The piece of hot iron is placed between these wheels, with one end in a notch, and the iron is bent double, bringing the two ends together, making it look somewhat like a clothes-pin, except that the clothes-pin should have a hole at the head, like in the piece of iron, for a handle. The ends of the bent iron are next hammered together, after which the coming ax is again heated. It is then taken to the steam hammers. The first hammer joins the parts of the iron firmly together, while the second, having on its face the mold of an ax, gives the iron the same shape. The sides are then made straight and even by a circular saw. But an ax in this shape could never be used to much effect, for cast-iron cannot be ground down to a fine enough edge. Steel can be ground, however, and so a piece of steel must be added to our iron ax. Two workmen take hold of the blade with pincers, and while one holds a sharp tool on the broad edge, the other strikes with a sledge. Into this split thus made, a piece of steel is slipped, and a steam hammer joins them firmly. After this, the ax is tempered, sharpened and polished; and, when the blade is furnished with a handle, the ax is ready for sale.--Yours truly, "THE DOCTOR." * * * * * The following is sent to us as written, without help, by a little girl nine years old. THE HISTORY OF A CAT. I am the family cat. I am not so very pretty, but they all like me very much. I have a pretty baby-kitten, and I have a daughter named Tortoise-shell. She is a pretty and good cat. She also has a baby-kitten prettier than mine. Mine has such big eyes that its little face does not look as cunning as my daughter's baby-kitten's face. My mistress is very good to me sometimes, but sometimes she pulls my tail and makes me mad, and I scratch her and then she slaps me back; but when she is good to me, and pets me, and gives me cake, then I purr to her. Once my mistress' brother had a dog given to him. This dog's name was "Captain." I did not like him one bit. My mistress' brother's friend tried to set the dog on me, but he would not come near me; so the boy let him alone.
