BY THOMAS W. KNOX.

During their stay upon the island of Java, Dr. Bronson and his young travelling companions took a trip on a railway from Batavia to Buitenzorg, in order that they might learn something of the interior of the island. While on this trip the boys observed, among other things, that the trees in some instances grew quite close to the track. Doctor Bronson explained to them that in the tropics it was no small matter to keep a railway line clear of trees and vines, and sometimes the vines would grow over the track in a single night. It was necessary to keep men at work along the track to cut away the vegetation where it threatened to interfere with the trains, and in the rainy season the force of men was sometimes doubled. "There is one good effect," said he, "of this luxuriant growth. The roots of the vines and trees become interlaced in the embankment on which the road is built, and prevent its being washed away by heavy rains. So you see there is, after all, a saving in keeping the railway in repair."

At several of the stations the natives offered fruit of different kinds, and nearly all new to our young friends. They had been told that they would probably find the mangosteen for sale along the road; they had inquired for it in Singapore, but it was not in season there, and now their thoughts were bent upon discovering it between Batavia and Buitenzorg. Two or three times they were disappointed when they asked for it; but finally, at one of the stations, when Fred pronounced the word "mangosteen," a native held up a bunch of fruit, and nodded. The Doctor looked at the bunch, and nodded likewise, and Fred speedily paid for the prize.

Perhaps we had best let Fred tell the story of the mangosteen, which he did in his first letter from Buitenzorg:

"We have found the prince of fruits, and its name is mangosteen. It is about the size of a pippin apple, and of a purple color—a very dark purple, too. The husk, or rind, is about half an inch thick, and contains a bitter juice, which is used in the preparation of dye; it stains the fingers like aniline ink, and is not easy to wash off. Nature has wisely provided this protection for the fruit; if it had no more covering than the ordinary skin of an apple, the birds would eat it all up as soon as it was ripe. If I were a bird, and had a bill that would open the mangosteen, I would eat nothing else as long as I could get at it.

"You cut this husk with a sharp knife right across the centre, and then you open it in two parts. Out comes a lump of pulp as white as snow, and about the size of a small peach. It is divided into sections, like the interior of an orange, and there is a sort of star on the outside that tells you, before you cut the husk, exactly how many of these sections there are. Having got at the pulp, you proceed to take the lump into your mouth, and eat it; and you will be too busy for the next quarter of a minute to say anything.

"Hip! hip! hurrah! It melts away in your mouth like an overripe peach or strawberry; it has a taste that is slightly acid—very slightly, too—but you can no more describe all the flavor of it than you can describe how a canary sings, or a violet smells. There is no other fruit I ever tasted that begins to compare with it, though I hesitate to admit that there is anything to surpass our American strawberry in its perfection, or the American peach. If you could get all the flavors of our best fruits in one, and then give that one the 'meltingness' of the mangosteen, perhaps you might equal it; but till you can do so, there is no use denying that the tropics have the prince of fruits.

"Everybody tells us we can eat all the mangosteens we wish to, without the slightest fear of ill results. Perhaps one might get weary of them in time, but at present we are unable to find enough of them. If anything would reconcile me to a permanent residence in the tropics, it would be the hope of always having plenty of mangosteens at my command.

"You may think," Fred added, "that I have taken a good deal of space for describing this fruit, but I assure you I have not occupied half what it deserves. And if you were here, you would agree with me, and be willing to give it all the space at your command—in and beyond your mouth. But be careful and have it fully ripe: green mangosteens are apt to produce colic, as Frank can tell you of his own knowledge."
