THE SCENT
Man sees with his eyes, hears with his ears, smells with his nose, tastes with his mouth, and feels with his fingers. One man's eyes see better, another man's see worse. One hears from a distance, and another is deaf. One has keen senses and smells a thing from a distance, while another smells at a rotten egg and does not perceive it. One can tell a thing by the touch, and another cannot tell by touch what is wood and what paper. One will take a substance in his mouth and will find it sweet, while another will swallow it without making out whether it is bitter or sweet.
Just so the different senses differ in strength in the animals. But with all the animals the sense of smell is stronger than in man.
When a man wants to recognize a thing, he looks at it, listens to the noise that it makes, now and then smells at it, or tastes it; but, above all, a man has to feel a thing, to recognize it.
But nearly all animals more than anything else need to smell a thing. A horse, a wolf, a dog, a cow, a bear do not know a thing until they smell it.
When a horse is afraid of anything, it snorts,—it clears its nose so as to scent better, and does not stop being afraid until it has smelled the object well.
A dog frequently follows its master's track, but when it sees him, it does not recognize him and begins to bark, until it smells him and finds out that that which has looked so terrible is its master.
Oxen see other oxen stricken down, and hear them roar
