"I can't make my legs carry me, Tom, and so we must depend upon you.

Go into the woods there by the creek, and sit down or stand still till you see something in the way of game, and then take good aim before you shoot, for we mustn't waste any of our powder." With this he shook the horn to ascertain how much remained in it, and was horrified to find it empty! Tom remembered that the last time he had loaded the gun he had used the last grain of powder in the horn.
"Well, then," said Sam, "we have only one charge of powder between us and starvation, and it won't do to waste that, Tom.

You can shoot pretty well when you have time enough to take good aim, and I suppose, if you make up your mind beforehand that you won't shoot till you know you can kill what you shoot at, it is safe enough.

At any rate we must risk it.
Remember, however, that you mustn't run the risk of wasting this load in your anxiety to kill the first thing you see to shoot at.

There is plenty of game in the woods, so if you can't get a sure shot at one thing, wait for another.
