"Well, what were you going to say about that collision?" asked Joe of Blake when Mr. Alcando had left them, at nearly midnight.
"I don't think it's exactly safe to say what I think," was Blake's response. "I think he is—suspicious of us," he finished in a whisper. "Let's watch and await developments."
"But what object could he—"
"Never mind—now," rejoined Blake, with a gesture of caution.
Several busy days followed the sinking of the Nama. The moving picture boys went through the Miraflores locks, making some fine films, and then proceeded on to the Pacific Ocean breakwater, thus making a complete trip through the Canal, obtaining a series of pictures showing scenes all along the way. They also took several views in the city of Panama itself.
Of course theirs was not the first vessel to make the complete trip, so that feature lost something of its novelty. But the boys were well satisfied with their labors.
"We're not through, though, by any means," said Blake. "We have to get some pictures of Gatun Dam from the lower side. I think a few more jungle scenes, and some along the Panama Railroad, wouldn't go bad."
"That's right," agreed Joe.
So they prepared to make the trip back again to Colon.
Once more they were headed for the locks, this time to be lifted up at Miraflores, instead of being let down. They approached the central pier, were taken in charge by the electrical locomotives, and the big chain was lowered so they could proceed.
