"Traffic" is the second of the three lectures published May, 1866,
in the volume entitled _The Crown of Wild Olive_. All these
lectures were delivered in the years 1864 and 1865, but the one
here printed was earliest. The occasion on which Ruskin addressed
the people of Bradford is made sufficiently clear from the opening
sentences. The lecture is important as emphasizing in a popular
way some of his most characteristic economic theories.
