A line in long array where they wind betwixt green islands,/They take a serpentine course, their arms flash in the sun—hark to the musical clank • Behold the silvery river.in it the splashing horses loitering stop to drink,/Behold the brown-faced men,each group,each person, a picture, the negligent rest on the saddles,/Some emerge on the opposite bank, others are just entering the ford — while,/Scarlet and blue and snowy white,/The guidon flags flutter gayly in lhe wind.
