Tom concealed it in an old wallet, as he thought it was less likely to attract attention there than in the new case he formerly used. Still he did not relax his vigilance, and his sleep for the next few nights was uneasy, as he awakened several times, thinking he felt a hand under his pillow.
At length Ned suggested that one of them sit up part of the night, and keep an eye on Tom's berth. This was agreed to, and they divided the hours of darkness into watches, each one taking a turn at guarding the precious map. But they might have spared themselves the trouble, for no further attempt was made to get it.
"I'd just like to know what Andy Foger's plans are?" said Tom one afternoon, as they were within a few miles of Seattle. "He certainly must have made up his mind quickly, after he saw the map, about going in search of the gold."
"Maybe his father proposed it," suggested Ned. "I heard, in our bank, that Mr. Foger has lost considerable money lately, and he may need more."
"I shouldn't wonder. Well, if they are going to Sitka, Alaska, to assemble their ship, I think they'll have trouble, for supplies are harder to get there than in Seattle. But we'll soon be on our way ourselves, if nothing happens. I hope all the parts of the RED CLOUD arrive safely."
They did, as Tom learned a few hours later, when they had taken up their quarters in a Seattle hotel, and he had made inquiries at the railroad office. In the freight depot were all the boxes and crates containing the parts of the big airship, and by comparison with a list he had made, the young inventor found that not a single part was missing.
"We'll soon have her together again," he said to his friends, "and then we'll start for Alaska."
"Where are you going to assemble the airship?" asked Mr. Damon.
"I've got to hire some sort of a big shed," explained Tom. "I heard of one I think I can get. It's out at the fair grounds, and was used some time ago when they had a balloon ascension here. It will be just what I need."
"How long before we can start for the gold valley?" asked the old miner anxiously.
