The two messmates had applied for and obtained leave to run up to Seoul and do a little sight-seeing as well as some shopping. It was believed that the ship would be ordered home soon, and every officer on board wanted some little knick-knacks from the heart of Korea. Bob and "Doc." Liddon, therefore, had half a dozen commissions to execute at the capital, as well as their own purchases to make.

"Now," said the midshipman, leaning back in his seat by the open window as the train began to move, "let's have a few statistics on Korea, old man."

"What do you want to know about it, youngster?" smiled Liddon, who was well used to this sort of appeal.

"Oh, I don't know enough about the place to ask questions," rejoined his companion languidly. "What is there interesting about it, anyway?"

"Well, perhaps the most interesting feature of the history of this country has been, up to a very recent date, its exclusiveness," said Liddon. "You know Korea has always been called 'The Hermit Kingdom.'"

"How big is Korea, anyway?" interrupted Bob, gazing out at the tawny waters of the river Hang-kang.

"Almost exactly the size of Minnesota—or, say, the size of New England, New Jersey, and Maryland. With the sea on three sides, and an uninhabited wilderness on the fourth, this independent little affair has been able to keep out foreigners, up to a very recent day."

"Independent? I thought China——"

"Oh, China holds a sort of suzerainty or protectorate over Korea, but practically it has governed itself. The King, or Sultan, or whatever he calls himself, has always been held sacred—to touch him with an iron weapon was sure death. Of late years foreign merchants have gained a foothold in the country, and travellers have visited it. You know Wiju, at the mouth of the Yalu, was declared an open port only last February."
