They visited two offices without success, and then came to a place located on a corner, with doors on both streets.

"h.e.l.lo!" cried Roger. "There is Mr. Van Blott just ahead of us! Is this the shipping firm with which Mr. Lawrence does business?"

"I don't think it is," answered Billy Dill.

"Then what is he doing here?"

"Must have a little business of his own," said Dave. "But I don't care.

Come along." Just then he was thinking only of his personal affairs.

They entered the office, which reeked of tobacco smoke and the smell of rum. In the rear was another office, and they were just in time to see the supercargo go into this, shutting a part.i.tion door behind him.

Looking around, Dave saw a clerk at a corner desk looking over some papers with an elderly German.

"I will be at liberty in a few minutes," said the clerk, in broken English. "Please to take seats," and he pointed to a couple of low benches set against the wall and the part.i.tion.

Billy Dill sat down on the bench along the wall and Dave and Roger upon that next to the part.i.tion, which was not over seven feet in height.

Save for the rattling of the papers at the corner desk the office was very quiet, and the boys readily heard the talk going on behind the part.i.tion.

"So you really have some goots on board?" came in a somewhat German voice. "I vos afraid you vould not bring any."

"Didn't I say I'd bring them, Baumann?" returned Jasper Van Blott. "I've got them, and the only question is, how am I to get them here, and when are you going to pay me?"

"I pay so soon as de goots is here," said the German shipping agent. "I not pay a dollar before."

"But you will send your men down to the dock?"

"Oh, yes, I do dot. Vot dime you vonts dem, hey?"

"To-morrow morning at eight o'clock, sharp. Tell them to watch me, and when I wave my handkerchief they can come forward and get the goods."

"How many poxes vos dere?"

"Sixteen, all told. You want to be careful and caution your men. I don't want Captain Marshall to learn what I am----"

The boys heard no more, for at this juncture the clerk came forward, having finished his work at the corner desk.

"What can I do for you?" he asked, blandly.

"I am looking for a man who is supposed to have left Cavasa Island by steamer, or sailboat, about two months ago," said Dave. "His name is Dunston Porter. Can you tell me if he shipped from here?"

The clerk looked over a book he drew from a desk.

"I see nothing of the name," he said, after a pause.

"You would have the name, if he had taken pa.s.sage from here?" questioned Roger.

The clerk nodded. Then, when he found that he could do nothing more for them, he dropped into an easy chair, lit a black-looking cigar and took up a newspaper.

"There is one more shipping office," said Billy Dill, as he led the way to the street. "We'll go there."

"Dave, did you hear that talk in the back room?" questioned the senator's son, as they were hurrying down the street.

"I did."

"What do you think of it?"

"I think the supercargo is up to some game, and we must tell Phil and Captain Marshall."

"That's just my idea, too, Dave. Let me see, the name of the firm was Baumann & Feltmuller, wasn't it?"

"Yes."

They were soon at the last of the shipping offices. Here the clerk could scarcely talk English, and they had to call in the services of a gentleman who chanced to be present and who could speak the native tongue. A booking list was consulted, and it was announced that Dunston Porter had taken pa.s.sage for Nanpi, on Sobago Island, just six weeks before.

"Six weeks!" cried Dave. "I hope he is there still. Now, how can I communicate with him, Roger?"

"You can send him a letter," answered Roger. "But you must remember that the _Stormy Petrel_ is going to Nanpi as soon as her cargo for this town is unloaded."

From the shipping clerk they learned that Dunston Porter had gone to Sobago alone--that is, without his partner, Mr. Lemington. A further searching into the shipping lists revealed the fact that the partner had sailed for Australia seven weeks past.

"I reckon they dissolved partnership," observed Billy Dill, "an' one went his way, an' tudder the other way. An' I likewise guess they didn't git thet treasure."

There was now nothing to do but to return to the bark, and this they did without delay. The boys found that Captain Marshall had gone ash.o.r.e on business, and so called Phil aside and related to him what had been heard in the office of Baumann & Feltmuller.

"You are right--there is something in the wind," said the shipowner's son. "I wish the captain was here, so I could consult with him."

"He'll be back soon, won't he?" questioned Roger.

"He said he might not be back until late this evening."

Phil was interested in what Dave had to tell about Dunston Porter, and said he would urge the captain of the _Stormy Petrel_ to set sail for Nanpi at the earliest possible moment.

It was not until ten o'clock that Jasper Van Blott came back to the bark. He immediately walked up to the first mate and the pair engaged in conversation for some time. Then the supercargo went to bed, and Roger and Dave did the same. Phil sat up, reading and awaiting the captain's return.

It was almost seven o'clock when the country boy sprang up and awakened the senator's son. Both hurried into their clothes and then into the cabin, where they met Phil, whose face was full of worry.

"What's the matter?" asked both.

"Captain Marshall hasn't come back yet."

"Hasn't come back?" e.j.a.c.u.l.a.t.ed Dave. "Do you mean to say he stayed away all night?"

"Exactly; and I don't know what to make of it."

"Did he say he might remain away?" came from Roger.

"No."
