The trained flea is one of nature's marvels. Everyone says so. A Bobby Burns might well write a poem on this "wee, timorous, cowerin' beastie," except that the flea is not, strictly speaking, timorous or cowering. A flea, when it is in good health and spirits, will not cower worth a cent. It has ten times the bravery of a lion--in fact, one single little flea, alone and unaided, will step right up and attack the noisiest lion, and never brag about it. A lion is a rank coward in comparison with a flea, for a lion will not attack anything that it has not a good chance of killing, while the humble but daring flea will boldly attack animals it cannot kill, and that it knows it cannot kill. David had at least a chance to kill Goliath, but what chance has a flea to kill a camel? None at all unless the camel commits suicide. And dogs! A flea will attack the most ferocious dog and think nothing of it at all. I have seen it myself. That is true bravery. And not only that--not only will one flea attack a dog--but hundreds of fleas will attack the same dog at the same time. I have seen that myself, too. And that multiplies the bravery of the flea just that much. One flea attacking a dog is brave; one hundred fleas attacking the same dog are therefore one hundred times as brave. We really had to give the dog away, he was carrying so much bravery around with him all the time. Think of educating an animal with a brain about the size of the point of a fine needle! And that was what Professor Jocolino had done. The flea is really one of nature's wonders, like Niagara Falls, and Jojo the dog-faced man, and the Ca�on of the Colorado. Pull? For its size the educated flea can pull ten times as much as the strongest horse. Jump? For its size the flea can jump forty times as far as the most agile jack-rabbit. Its hide is tougher than the hide of a rhinoceros, too. Imagine a rhinoceros standing in Madison Square, in the City of New York, and suppose you have crept up to it, and are going to pat it, and your hand is within one foot of the rhinoceros. And before you can bring your hand to touch the beast suppose it makes a leap, and goes darting through the air so rapidly that you can't see it go, and that before your hand has fallen to where the rhinoceros was, the rhinoceros has alighted gently on top of the City Hall at Philadelphia. That will give you some idea of the magnificent qualities of the flea. If we only knew more of these ordinary facts about things we would love things more.
