At this very moment, Sandy, Leander, Gilbert and Dink were together, in Sandy's little garret room. Sandy closed the door carefully, locked it, and called his companions about him in the middle of the room. "Boys," he whispered, "afore I sez anythin', I wants yer to gimme yer word, honor bright, an' cross yer heart three times, that yer won't spout a syllable of what I tells yer to a soul." All were agreed, and the boy began: "Now, it's this 'ere way. My boat wuz stolen an' left, right below the upper bridge, an' I foun' footprints an' this 'ere piece of ribbon, which Gil knows b'longed to his sister, for she wore it round her hair. Willie Bagner's skiff's bin stolen, an' I believe the party that took it hez got little Lily, because I foun' the hoop I give her, an' this envellup in the same place, an' it seems to me the galoot whose name's on it is hid somewhere up the river, an' I'm goin' after him if I has to go alone." "But you won't go alone, while I'm alive," insisted Leander, intensely excited. "An' I'm goin', too, even if I never come back," added Dink, taking it for granted that he was needed. "And you must take me," said Gilbert imploringly. The four boys grasped one another's hands, and Sandy declared in a solemn tone: "We'll stick together to the bitter end." "What's your plan?" asked Leander, with great interest. "Without breathin' a word to a soul, to-night about nine o'clock we wants to leave the boat-house, you an' Dink in one skiff, an' me an' Gil in t'other, an' sneak up the river, an' try so nobody won't see us. When we gits to the upper bridge, paddle in as close to the Causeway on the right, as we kin, huggin' the marsh all the way. Jest before we git to Beaver Dam, there's a deep gut that runs 'longside of it fer a hundred yards or more. Foller me in there, Leander, an' stay hid till I sez move. Don't speak a word, from the time we push off till I sez so. Beaver Dam is the lonesomest creek in the world, an' mebbe Gil's little sister is kept in one of them ol' shacks what muskrat hunters live in, in the spring an' summer. If them galoots is in there, they're mighty apt ter come out late at night, when they don't expec' nobody's roun'. Of course, nacherelly they have some plan about gettin' paid fer little Lily, an' they ain't a-goin' to stay in hidin' without tryin' to find out the lay er the land, an' jest how hot the police is on their trail. My idee is to go an' lay in ambush fer 'em all night. If they don't come out, we'll explore in the mornin', an' if we don't find 'em hidin' roun' Beaver Dam, then we'll lay low all day, an' push up the river to-morrow night. But somehow, I think that's the place they would pick out to hide in. 'Tain't one person out er a million that would know how to git through Beaver Dam without gittin' lost, an' I'm a recollectin' I took Tom Foley through there onct an' that's why I'm goin' there to-night. I knows it so well, I could go through with my eyes shet.
