Grocott & Ward, comps. Grocott’s Familiar Quotations, 6th ed. 189-?.

Tread

To tread the walks of death he stood prepared,
And what he greatly thought, he nobly dared.
Pope.—The Odyssey, Book II. Line 312.

And so to tread
As if the wind, not she, did walk,
Nor press’d a flower, nor bow’d a stalk.
Ben Jonson.—Vision of Delight.
