"I once took a journey to Los Angeles," said Phil. "But I went and returned by the southern route, so this is new to me also."

"I have never traveled anywhere—that is, since I can remember," put in Dave. "But I am sure I am going to like it—that is, if I don't get seasick when I am on the ocean."

"Oh, I suppose we'll all get our dose of that," responded the senator's son.

"Maybe not," said Billy Dill. "Some gits it, an' some don't."

Nightfall found them well on the second portion of their journey to San Francisco. There was an observation car on the train, and the whole party spent hours seated on camp-chairs, viewing scenery as it rushed past them. Now and then, for a change, they would read, and Billy Dill would smoke, and the boys often talked over what was before them.

"My father said I might tell you the object of my trip," said Phil to his chums. "But he does not want anybody else to know of it, unless it becomes necessary for me to say something to the captain. The supercargo of the ship is a man named Jasper Van Blott. He has worked for my father for some years, and my father always thought him honest. But lately things have happened which have caused my father to suspect this supercargo. He sometimes disposes of certain portions of a cargo, and his returns are not what they should be."

"Then you are to act as a sort of spy," said Roger.

"I am to watch everything he does without letting him know exactly what I am doing. And when he makes a deal of any kind, I am to do my best to ascertain if his returns are correct. If I find he is honest, my father is going to retain him and increase his salary; if he is dishonest, my father will discharge him, and possibly prosecute him."

"Have you ever met this Van Blott?" asked Dave.

"Once, when he called on my father two years ago. He is a smooth talker, but I did not fancy his general style. He is supposed to be a first-class business man, and that is why my father has retained him. I do not believe Captain Marshall likes him much, by the way he writes to father."
