into Dave's room.

"Now, what do you make out of all we have heard and seen?" breathed
Dalzell tensely.

"Just what the admiral told us," answered Darrin.

"Nothing more?" pressed Dan.

Dave was thoughtful for a few moments before he replied:

"Danny, boy, we have our orders from the commander of the fleet. If we
encounter Mr. Green Hat anywhere in the future, we are to report the
fact. That is the extent of our instructions, and I think we shall do
very well not to think too much about the matter, but to be ready, at
all times, to follow our orders."

"I was in hope that you could evolve something more romantic than
that," returned Dalzell disappointedly.

"It is very likely," went on Dave judicially, "that we have already
had as large a hand in the affair as we are going to have. I doubt if
we shall hear anything more of Mr. Green Hat; even if we hear of his
further deeds, we are not likely to have any personal part in them."

"I'm disappointed," Dan admitted, rising. "I'm going to bed now, for I
have to be up at half-past three, to turn out on watch at eight
bells. You, lucky dog, have no watch to stand until after breakfast.
Good night, Dave!"

"Good night; and don't dream of Mr. Green Hat," smiled Darrin. "You'll
never see him again."

In that prediction Ensign Darrin was destined to find himself
fearfully wide of the mark. Mr. Green Hat was not to be so easily
dropped from the future calculations of the youngest naval officers on
the "Hudson."

None of our readers require any introduction to Dave Darrin and Dan
Dalzell, ofttimes known as "Danny Grin." These two fast friends in the
naval service were members of "Dick & Co.," a famous sextette of
schoolboys in Gridley. Dick Prescott, Greg Holmes, Dave Darrin, Dan
Dalzell, Tom Reade and Harry Hazelton first appeared in the pages of
"THE GRAMMAR SCHOOL BOYS SERIES," in which volumes were described the
early lives of these young American schoolboys.

We found the six boys again in the pages of the "HIGH SCHOOL BOYS
SERIES," in the volumes of which the athletic triumphs of Dick & Co.
were vividly set forth. In the "HIGH SCHOOL BOYS' VACATION SERIES"
were recounted their further adventures.

At the conclusion of their high school careers the six chums separated
to seek different fields of endeavor. Dick Prescott and Greg Holmes
secured appointments as cadets at the United States Military Academy
at West Point, as narrated in the "WEST P
