It had been an ideal costume to struggle through the slob ice.
Here was no slob ice to be forged through at full steam, but a solid mass, like a bar of iron, lying across the path.
It was not clear water, but the "slob ice," probably too heavy for a rowboat to pierce, which lay between the pan and the beach.
Then us come t' th' slob ice where th' pan 'ad ground together, an' 'twas all thick, an' that was worse'n any.
On the third day by wonderful luck he gaffed an old seal in the slob ice.
