scarce = in short supply OR barely or hardly (by a small margin)
...In one day there scarce can be Those perils wrought whose dread yet haunteth me.†
But like a thing nailed down The burning gold held fast the anadem, And through her locks, the more she scattered them, Came fire the fiercer, till to earth she fell A thing save to her sire scarce nameable, And strove no more.†
...I scarce understand......O God, thou hast broken me!†
