Old penny boats, new-brushed,
Till they looked quite smart and clean,
Their bows plebeian pushed
More nobby craft between.
"Give 'em coke!" the captains cried; and each one
Charged his furnace to the lips,
Till steamers, yachts, and ships,
The funnel's clouds eclipse—
Dark and dun!
In vain! in vain! in vain!
