Under the Maples by John Burroughs

I have heard a story of a young artist who, after painting a picture of a horse facing a storm, was not satisfied with it, and, feeling that something was wrong, asked Landseer to look at it. Instantly the great artist said to him, "Turn the horse around."

The cow turns her head to the storm, the horse turns his tail. Why this difference? Because each adopts the plan best suited to its needs and its anatomy. How much better suited is the broad, square head of the cow, with its heavy coating of hair and its ridge of bone that supports its horns, to face the storm than is the smooth, more nervous and sensitive head of the horse! What a contrast between their noses and their mode of grazing! The cow has no upper front teeth; she reaps the grass with the scythe of her tongue, while the horse bites it off and loves to bite the turf with it. The lip of the horse is mobile and sensitive. Then the bovine animals fight with their heads, and the equine with their heels. The horse is a hard and high kicker, the cow a feeble one in comparison. The horse will kick with both hind feet, the cow with only one. In fact, there is not much "kick" in her kind. The tail of the cow is of less protection to her than is that of the horse to him. Her great need of it is to fight flies, and, if attacked in the rear, it furnishes a good hold for her enemies. Then her bony stern, with its ridges and depressions and thin flanks, is less fit in any encounter with storm or with beast than is her head. On the other hand, the round, smooth, solid buttocks of the horse, with their huge masses of muscles, his smooth flanks, and his tail -- an apron of long, straight, strong hair -- are well designed to resist storm and cold. What animal is it in Job whose neck is clothed with thunder? With the horse, it is the hips that are so clothed. His tremendous drive is in his hips.
