"No express train was ever made that's fast enough for me to-night," muttered Lieutenant Dick Prescott between set teeth.

The running lights were out, for it was nearly dark when the "Restless" had left Agua Dulce. Only the movement of a switch was needed to turn them on.

"Ever been to Holmesville?" demanded Dave Darrin, turning almost fiercely on Tom Halstead when he showed his head on deck.

"No, sir."

"Wouldn't know the place by sight?"

"No, sir."

"Nor I, either—from the water front," groaned Darrin. "But surely you have some chart of the river?"

Tom Halstead was already out of sight again. When he came on deck he remarked:

"I've been looking at the chart. Now, I'll know Holmesville to a dot when we sight the place."

"Nice sort of a town some one took the trouble to name after me, isn't it?" grunted Lieutenant Holmes.
