She halted again, realizing the young man’s expression of countenance and his attitude with the other girl.  She was quick enough of comprehension to see that this other girl had the advantage of her with the captain of the Seamew as well as with her relatives.

In Ida May’s own artful mind she had decided that a smart girl could easily “twist that fellow around her finger.”  This girl who had usurped her name and identity had already succeeded in doing just that!  The girl from Hoskin & Marl’s halted, the wrathful flush came back into her pretty, insipid face, and she almost screamed: 

“What’s got into you folks?  Are you all crazy?  Why, that fellow knows who I am well enough!  I bet he brought that girl here himself and palmed her off on you.”  She turned to blaze at Cap’n Ira and Prudence.  “He picked her up somewhere—­some low creature!  But I’ll show them both up; that’s what I’ll do.  I’ll make them both sorry for cheating me.  I guess you folks have got a heap of money, and that fellow and that girl are trying to get it all.  But they won’t.  I’ll have my rights or—­”

“Belay that!” exclaimed Cap’n Ira suddenly.  “We won’t listen to no more such talk.  Whatever we have got—­Prudence and me—­and whoever you be, young woman, I cal’late we’ll do about as we please with it.  I think you have broke loose from them that had you in charge.  And they ought to be hunting for you.  Leastways, I guess you’d better be sent back to ’em.”

“I’m her niece, I tell you!” reiterated Ida May, pointing at Prudence, who shrank again from the vehement girl.

Then she whirled on Tunis.  She clasped her hands.  Into her rage was distilled some fear because of Cap’n Ira’s grim words.

“You got to help me,” she said to the younger man.  “You know who I am, and you daren’t deny it!”

No man can pace the quarter-deck—­even of a packet of no greater importance than the Seamew—­without having developed the sterner side of his character.  And Tunis Latham came of a long line of shipmasters who had handled all sorts and conditions of men.  If a skipper does not command the respect of his crew, he’ll not get far!

The grim mask that had settled upon the countenance of the captain of the Seamew might have stayed the tongue of a more courageous person than Ida May Bostwick.  His severe look and manner appalled her.

“See here, young woman, I don’t like your tone; nor do I understand what you mean.  Who do you say this is, Ida May?” he added more gently, looking down into Sheila’s face again.

“She—­”

“I’m Ida May Bostwick.  You know I am!” wailed the visitor.  “Why—­why, you must remember me, Tunis Latham.  Don’t you call her by my name.  I won’t stand it.”

“Mad as a hatter!  Mad as a hatter!” muttered Cap’n Ira to Prudence.

“There’s something the matter with her, is there?” proceeded Tunis thoughtfully, eying the claimant as though she was indeed an utter stranger.  “How did she get here?  What does she want?”
