to meet the steamer. People who are going to smuggle anything rarely take pains to conceal their contraband goods till they are nearing port. We know something about the matter, you see. Moreover, we know would-be smugglers who don't make a profession of it are very careless, talkative about what they are going to smuggle, and apt to give themselves away. By sending a good, smart spotter ahead we learned all about the people we've exposed."

"That game may work very nicely with amateurs. But it would not go with a professional smuggler by any means."

"I quite agree with you," assented Harry.

"Well," said the Collector, "I'm quite satisfied with your performance, Mr. Brady, and am convinced that you are the very men to run down the big smuggler I am so anxious to see arrested."

"We'll do our best," said Old King Brady.

The Collector and the inspectors then went away.

As they were leaving the pier, the quick, keen eyes of Harry observed a young girl on the steamer acting in a mysterious manner.

She was standing in the gangway, peering out one of the port holes and sharply watching the departing officials.

Every time one of them chanced to glance back, she suddenly dodged down behind the bulwark out of sight.

She was a beautiful girl of about sixteen, handsomely clad in a short dress and zouave waist of fine silk, while a stylish big Gainsborough hat with black ostrich plumes crowned her short, yellow, curly hair.

Her skin was as white as milk and she had a pair of big brown eyes, a pretty little Grecian nose and rosebud lips.

Young King Brady was charmed with her beauty, yet his suspicions of her actions were aroused to the fever point.

He touched his partner on the arm and pointed at her.

"See there!" he exclaimed. "What can she be up to?"

"We'd better keep an eye on her, Harry," returned the old detective, after a careful survey. "It looks to me as if she were up to some trick. She wouldn't be watching those inspectors' departure that way unless it was of vital importance to her."

"But surely she can't be so silly as to think there are no officers left here. Everyone knows that a couple remain constantly on the watch in their office at the entrance to the dock."

"Ha! What's that? She's waving her handkerchief to that man who is coming out on the pier from West street."

Young King Brady gazed keenly at the person in question and suddenly recognizing him he exclaimed in excited tones:

"Why, it's Paul La Croix, the diamond smuggler!"

"So it is, by thunder!"

"And this beautiful girl must be his daughter, for she greatly resembles him."

"Harry, I believe that pair are up to some crooked work!"

"We can find out by watching them."

La Croix now went aboard the steamer and joined the girl in the gangway.

CHAPTER III.

CAUGHT IN AN ELEVATOR.

The Bradys felt convinced that the smuggler and his daughter were working some scheme to take some valuables ashore, duty free.

Closely watching the pair they saw them enter the cabin.

Following them in, the Bradys observed the pair gliding swiftly down a passage, out on which opened the doors of several staterooms.

La Croix and his daughter entered one of these rooms.

Rushing forward, the Bradys listened outside the partition and heard the man ask:

"Did you geet eet, Clara?"

"Yes, papa," replied the girl in a low, pleasant tone of voice. "After I left you on Maiden Lane, I came right here and mingled with the throng waiting to meet the various passengers. As soon as the gangplank was down, I slipped aboard and met the steward. He had the parcel and gave it to me."

"Open eet so we can distribute ze jewelry about our pairsons. Zen we geet ze sings ashore ver' easy, an' no wong weel see ze package bulge out our
