CHAPTER XXVII. LEONARD DE CARTIENNE. 

We all three stood and looked at one another for a moment, Milly Hart with her finger still pointing to the vacant place where the photograph had been. Then Cecil broke into a short laugh. 

"We're looking very tragical about it," he said lightly. "Mysterious joint disappearance of Leonard de Cartienne and a photograph of Mr. Hart. Now, if it had been a photograph of a pretty girl instead of a middle-aged man, we might have connected the two. Hallo!" 

He broke off in his speech and turned round. Standing in the doorway, looking at us, was Leonard de Cartienne, with a slight smile on his thin lips. 

"Behold the missing link--I mean man!" exclaimed Cecil. "Good old Leonard! Do you know, you gave us quite a fright. We expected to find you here and the room was empty. Are you better?" 

"Yes, thanks! I'm all right now," he answered. "I've been out in the yard and had a blow. What's Milly looking so scared about? And what was it I heard you say about a photograph?" 

"Father's likeness has gone," she explained, turning round with tears in her eyes. "It was there on the mantelpiece this afternoon and now, when we came in to look at it, it has gone!" 

"I should think that, if it really has disappeared," de Cartienne remarked incredulously, "the servant must have moved it. Ask her." 

Miss Hart rang the bell and in the meantime we looked about the room. It was all in vain. We could find no trace of it, nor could the servant who answered the summons give us any information. She had seen it in its usual place early in the morning when she had been dusting. Since then she had not entered the room.

Rochester ( or ) is a city on the southern shore of Lake Ontario in western New York State. Rochester is the third most populous city in New York, with over 210,000 residents, and its metropolitan area has a population of nearly 1.1 million people. 

Rochester was one of America's first boomtowns, rising to prominence as the site of many flour mills along the Genesee River, and then as a major hub of manufacturing. Several of the region's universities (notably the University of Rochester and Rochester Institute of Technology) have renowned research programs. In addition, Rochester is the site of many important inventions and innovations in consumer products. The Rochester area has been the birthplace to such corporations as Kodak, Western Union, Bausch & Lomb, Gleason and Xerox that conduct extensive research and manufacturing in the fields of industrial and consumer products. Until 2010, the Rochester metropolitan area was the second-largest regional economy in New York State, according to the U.S. Internal Revenue Service, after the New York City metropolitan area. Rochester's GMP has since ranked just below that of Buffalo, New York, while still exceeding it in per-capita income. 

The 25th edition of the "Places Rated Almanac" rated Rochester as the "most livable city" in 2007, among 379 U.S. metropolitan areas. In 2010 "Forbes" rated Rochester as the third-best place to raise a family. In 2012 Kiplinger rated Rochester as the fifth-best city for families, citing low cost of living, top public schools, and a low jobless rate.

CHAPTER XX—LANDING ON CAVE ISLAND 

At the end of a week Dave was more worried than ever. Each day he and his chums went down to the shipping offices and each day returned to the hotel disappointed. Not a word had been heard concerning the missing vessel and those on board. 

The _Golden Eagle_ was all ready to sail on her return trip to the United States, but Phil told Captain Sanders to wait. 

“Perhaps we’ll hear to-day,” he said, and this was repeated day after day. 

It was very warm and the boys were glad they had brought along some thin clothing. They scarcely knew what to do with themselves, and Dave was particularly sober. 

“I suppose Mr. Wadsworth and the rest are waiting to hear from me,” he said to his chums. “But what is the use of sending a message when I haven’t anything to say?” 

Another Sunday passed, and on Monday the boys visited the _Golden Eagle_, and then went with Captain Sanders to the nearest shipping office. 

“Something is going on!” cried the senator’s son, as he noticed an unusual crowd congregated. “Must be news of some sort.” 

“Let us find out what it is!” returned our hero, quickly. 

“The _Emma Brower_ has been heard from,” said a man, standing near. “That’s the vessel that was missing, don’t you know,” he added. 

“What of her?” asked Dave. 

“Went down in that terrible storm we had about ten days ago.” 

“Down!” gasped all of the boys, while Captain Sanders looked the concern he felt.
