The stem that found its way so surely to the upper world knows not less surely the way back again; and when its white blossom has opened for the last time, and then wrapped its green cloak about it again, not to be unfolded, the chambered stem coils backward, and carries it safely to the bottom, where its seed may ripen in the soft, dark mud, and prepare for another summer.

THE CARRYING TRADE

Who wants to engage in the carrying trade? Come, Lottie and Lula and Nina and Mary, all bring your maps, and we will play merchants, and see what is meant by the carrying trade.

Lottie shall have the bark "Rosette," and sail from Boston to Calcutta; Lula, the steamer "North Star," from New York for Liverpool; Mary shall take the "Sea-Gull," from Philadelphia to San Francisco; and Nina is owner of the "Racer," that makes voyages up the Mediterranean. Are we all ready for our little game?

Lottie begins, and she must find out what Boston has to send to Calcutta. Don't send indigo or saltpetre or gunny-bags or ginger; for, even should you have these articles to spare, Calcutta has an abundance at home, and you must discover something that she needs, but does not possess. "Ice," says Lottie. "Yes, that is just the thing, because Calcutta has a hot climate, and does not make her own ice: so load the 'Rosette' with great blocks well packed, and start at once, for your voyage is long."

And now we will go with Lula to the North River pier, where her great steamer lies, and see what she intends to carry to Liverpool. Bales of cotton, barrels of flour, of beef, and of petroleum. All very good, so good-by to her. In a few weeks we will see what she brings back.

Come, Mary, what has Philadelphia for San Francisco? Oh, what a load the "Sea-Gull" must take of machinery, steam-engines, tobacco, and oil; and such a quantity of other things, that the "Sea-Gull" will need to make many voyages before she can take them all. We load her at this busy wharf, where the coal-vessels are passing in and out for New York and Boston, and the steamers are loading for Europe, and the little coasters crowding in one after another; and away we go for the voyage round the "Horn," where the "Sea-Gull" will meet her namesakes, and perhaps some stormy winds besides.

Meantime Nina's "Racer" has been stored full of cotton cloths and hardware, and has raced out of Boston Harbor so swiftly that fair winds will take her to Gibraltar in three weeks.

And so you have all engaged in the carrying trade; but as yet you have carried only one way. To complete the game, we must wait for Lottie to bring the "Rosette" safely home with salt-petre and indigo and hides and ginger and seersuckers and gunny-cloth. And the "North Star" must steam her quick way across the Atlantic, and return with salt and hardware, anchors, steel, woolens, and linens. Mary must beat her way round Cape Horn, and home again with wool and gold and silver. And the swift "Racer" must quickly bring the figs and prunes and raisins, and the oranges and lemons, that will spoil if they are too long on the way.

So children may play at the carrying trade, and so their fathers and uncles may work at it in earnest: and so also hundreds of little workers are busy all the world over in another carrying trade, which keeps you and me alive from day to day; and yet we scarcely think; at all how it is going on, or stop to thank the hands that feed us.
