Dan gave his friends what he considered good advice during the passage, and when the boat was nearing the slip on the Jersey side, summed up his instructions with a statement which electrified them all.

"You fellers are to hang 'round Weehawken till 'long towards dark, when Plums must come down to the ferry-slip. I'm goin' back to New York to fix up my business, so's I can stay with you till the worst of the trouble is over."

"Are you countin' on runnin' away with us?" Master Plummer asked, in surprise.

"That's jest the size of it. You fellers don't seem to know scarcely anything at all about takin' care of yourselves, an' if I don't 'tend to business you'll both be in jail before to-morrow mornin'. I'm goin' to size up things 'round perlice headquarters to-day, an' then come over to look after you. Jest as soon's the boat touches the slip, you two take a sneak, find some place where you can hide till night, an' then watch out for me."

Five minutes later, the fugitives stepped on Jersey soil, and Master Fernald's scouts were deployed to guard against an attack from the enemy until the two boys were lost to view in the distance. Then the amateur detective said, in a tone of grim determination, "Now, fellers, we'll go back, an' size up the cops in New York."
