"No more collisions, I hope," his chum ventured. "Do you know, Blake, I've wondered several times whether that one to-day was not done on purpose."
Blake stared at his chum, and then, to Joe's surprise replied:
"And I've been thinking the same thing."
"You have?" Joe exclaimed. "Now I say—"
"Hush!" cautioned Blake quickly, "he's coming!"
The door of their stateroom opened, and Mr. Alcando entered. He had a room across the corridor.
"Am I intruding?" he asked. "If I am—"
"Not at all. Come in," answered Blake, with a meaning look at his chum.
"I wanted to ask you something about making double exposures on the same film," the Spaniard went on. "You know what I mean; when a picture is shown of a person sitting by a fireside, say, and above him or her appears a vision of other days."
"Oh, yes, we can tell you how that is done," Joe said, and the rest of the evening was spent in technical talk.
