'Bout half way, thar's a big break in the path.
Hit's jess a long step acrost hit.

Take one step arter I say thet I'm acrost; the feel keerfully with yer left foot fur the aidge o' the break, an' then step out ez long ez ye kin with yer right.

That'll bring ye over.

Be shore o' yer feet, an ye'll be all right." Harry trembled more than at any time before.
