“We will search every one of them we find,” declared Frank. “There certainly are vast treasures under the sea, and we are not brilliant if we do not find them.”
This revived Bell’s hopes greatly, and he was once more glib and gay.
For miles, however, the Dart now sailed on over unknown depths into which it was not safe to descend.
These were the lowermost depths of the great deep where the pressure would be so great that a huge ship sunken there would be crushed into a shapeless mass.
But it was not likely that many interesting things would be found down there even if the Dart was able to go.
So none were much disappointed.
The sea soon began to change again.
The water seemed a peculiar olive tint, and Frank, who had studied the phenomena, said:
“We are coming to a submarine forest. You shall see.”
His prediction proved correct.
