A man riding a mule, his whip raised, another mule loaded with grass alongside

What you see

Two mules move toward the left. The first all but vanishes beneath an enormous bundle of green grass, with only its head and legs showing. Behind it, a barefoot man rides the second in a striped gray poncho, blue breeches and a white hat, raising his whip high overhead. The curl of the lash closes the composition at the upper right.

The bundle steals the show: a green mass built from short, pointed strokes, like loose blades of grass. The mules are nearly white, with gray shading and dark legs, and the ground is a strip of brown washes. Notice the shaggy brown pelt over the saddle and the raised foreleg of the rider's mule.
