"Possibly it is he," admitted the Marshal. "There have been some shady deals carried through down here lately. Some smuggling and a bad wreck and one or two other things that the United States Government feels should be explained. Someone must explain."

"Well, we'll help you all we can when the time comes," cried Tom heartily. "I'm sure we'll do that."

"Here comes somebody on the wharf," declared Arnold with a hand on Rowdy's collar. "Wonder who it is now?"

"That's the watchman," said Harrison. "He's got the shovels."

As the watchman delivered the implements to the Marshal he was requested to keep an eye on the Fortuna. This he promised to do.

"I have an idea," explained Harrison in parting, "that the parties I am expecting to call will be across the bay, but in case they should come, hold them even if you have to resort to violence."

"A few more and we'd have a load," remarked Jack as the skiff with its unusual cargo pulled away from the Fortuna. I'm glad there are enough boys to go around so we can have one to each oar."

"We have got a crowd, sure enough," admitted Frank. "Did you bring a gun with you in case something might turn up?"

"Indeed I have," replied Jack. "I am pretty sure the others have theirs, too," he added. A vote of the crowd showed he was right. Every member of the Fortuna's regular crew had an automatic.

A short time only was required for the passage across the bay, between the supports of the railroad bridge and around the point to a spot as near the fort as Harrison deemed best to approach.
