Why, it's a machine by which very low sounds, that don't seem to be sounds at all, may be made to grow so loud and clear that you can easily hear them. If any of you come across one of these things, my dears, just take it to some quiet green spot, and coax it to let you hear the grass grow.

There's one feature of the microphone that is likely to be troublesome; it makes loud noises sound hundreds of times louder. Something must be done, therefore, to prevent the use of these machines on any Fourth of July. That would be what nobody could stand, I should think.

A CRAB THAT MOWS GRASS.

Isn't this dreadful? In India—a long way off, I'm glad to say—there is a kind of crab that eats the juicy stalks of grass, rice, and other plants. He snips off the stalks with his sharp pincers, and, when he has made a big enough sheaf, sidles off home with it to his burrow in the ground, to feast upon it.

Ugh! I hope I shall never hear the cruel click of his pincers anywhere near me!

WASHERWOMEN IN TUBS.

Over here, as I've heard, the clothes to be washed are put in tubs, and the washerwomen or washermen stand outside at work. But I'm told that in some parts of Europe the washerwomen themselves get into the tubs. They do this to keep their feet dry. The tubs or barrels are empty, and are set along the river banks in the water, and each washerwoman stands in her tub and washes the clothes in the river, pounding, and soaping, and rinsing them, on a board, without changing her position.

MICE IN A PIANO.

Chicago, Ill.

Dear Jack: I have long wished to tell you of a little incident that occurred in our family.
