A good runner wins as many races with his head as with his feet. All college crows which recently competed on the Hudson were made up of muscular giants but in the stern of every shell there was a little fellow a'hold of the rudder strings. He also times and counts the stroke. The muscle of the crow would be useless without the brains of the coxswain.
Brains weigh more than beef.
David slew Golioth. The same is true in the animal world. He is no larger than a man's finger and weighs about four ounces. In Alaska he is found in the same range with the huge brown bear. The Alaska brown bear is the largest of all living carnivora and famous as a fighter, but if the little weasel were increased to the size of the brown bear and his stock of bravery increased in like measure one weasel could whip all the bears in Alaska and likely would.
