me doing two things--having a mouthful
of milk, and then a mad gallop. And he does both very suddenly. He
likes to have his joys suddenly.

A kitten or a puppy dog is different, and is nearly always doing
something. It tumbles head over heels, or chases its own tail, or
keeps frisking about in some way or other most of the time. But the
buffalo calf is not like this; and when you see him standing quite
still, staring at nothing, you can never tell whether he is going to
be hungry for a mouthful of milk the next minute, or whether he is
going to break into a frantic race.

But, you may ask, while he and all the other calves are playing about
like that, is there no danger?

No, there is no danger, for the Papas are taking good care of the
Mammas and the children, as I have told you before.

But, you may say, the Papas do not seem to be doing anything; they are
just feeding and moving along. Then how are they taking care of the
Mammas and the children?

Yes, but look carefully! See how close the horn of one Papa is to the
horn of the next one! Why, there is not more than a couple of yards
between the two! If there were any sudden danger, it would not take
more than two or three steps for them to close up, and stand horn to
horn.

_How Buffaloes Know Danger is Coming--Three Ways_

"But how could they _know_ if any danger were coming?" you may still
ask.

They could know it in three ways: they could _smell_ the danger, or
_hear_ it, or _see_ it. I shall tell you how they do all that.

First, if the danger came from the direction in which the wind was
blowing, they would sniff the air, and so _smell_ the danger. If the
danger were a tiger, the buffaloes could smell him half a mile off;
that is about as far as ten blocks in a city. And if the wind were not
blowing that way, the buffaloes could still smell the tiger five
blocks away. They could smell the tiger, or any other danger, even if
it came from behind.

The second way of finding out the danger is to _hear_ it. As I said a
little while ago, if you should put your foot on a rotten twig, the
buffaloes could hear the sound of it as far off as five blocks. And
even if the danger came from behind, or from the side, or from
anywhere, they could still hear it coming, if it made the least bit of
sound that you and I could not hear.

The third way of finding out the danger is to _see_ it. The buffaloes
do that by keeping a lookout nearly all the time. I shall sho
