Recalls a clatter
Of hoofs where traffic is flashing in rows;
In this line the speaker reminisces of the time when his work was needed, hes references the “clatter of hoofs where traffic is flashing in rows” referring to a time when the street beyond his place of business was not filled with cars, but with horses.(this can be further inferred from line five “Or the hiss when a new shoe toughens in water”) This line also shows the speakers resentment of change, and how the modern world finds him obsolete.
