"Then you mean that Dog, Cast, Have stands for DCH and that DCH stands for a whole sentence?"
"Yes. Oh, do hurry! Never mind, though; they're just answering her with the same thing."
Joan searched through the fluttering pages, looking up and down the columns of signal-letters and their meanings.
"DCF—DCG— Here it is! DCH: Dress. Officers and crews will, the same as yesterday. Why, it really does mean something!" laughed Joan triumphantly.
"Of course it does," said Garth. "That's the uniform order for the day."
"Oh, what fun! I supposed that no one but Admirals, and such people, really knew what the signals meant."
"Anybody can," Garth said. "Of course they don't send war-messages that way, but they don't care who knows about these ones."
"Oh, look!" Joan cried delightedly. "One of the others is doing something! Quick, Garth!"
She snatched up the glasses, while he peered through the telescope.
"Oh, what is it?" he cried. "Mike, on top."
