"Jimmie's a stupid boy. See this fellow." The old man held the locust toward Betty. "With its upper lip, broad, you see; and there is the lower lip made in two scallops, and there's a short feeler on either side, and another pair of soft jaws with a feeler. Hidden away under those parts is a pair of dark-brown, horny jaws which open like two big swinging gates." "What makes them so big?" "The better to eat you with, my dear." The guide worked his jaws until Betty, half afraid and half pleased, screamed and ran behind a tree. "Oh, how they can eat!" growled the old man, "more than any little girl or boy I ever knew! Years and years ago, when your mamma was a baby, they mounted up into the air from the Rocky Mountains and flew eastward in a great cloud. Down they swooped upon the fertile valleys in rustling hordes, and ate everything in sight--grass, grains, vegetables, and bushes. They ate and ate and ate until they had eaten up fifty million dollars' worth of food, and the poor farmer could hear nothing but the sound of the chewing of those ever-swinging jaws. Now, be off, little girl, or my pails won't be clean." "Oh, please, sir, just tell me how they jump and breathe." "Dear, dear, see this fellow!" He had wet a little grain of maple sugar, and a tiny meadow grasshopper which had alighted on his knee was pushing the sweet stuff into its mouth with both fore legs. "Child, you must never," said the old man, savagely, "push your food in that way." "Please, sir," answered Betty, "I never do, because I eat with my fork and my knife. Please, sir, are they happy when they jump?" "Looks like a horse, doesn't it?" asked the old man. "It's made for jumping. Think of all the training it takes to make a jumper of your brother at school. Well, this chap can jump ten times as far. It's born with a better jump than the longest-legged boy you ever saw. But the locust might get its head cut off when jumping if it weren't for this little saddle that covers the soft part of the neck. Mr. Locust can't always look before he leaps, as a little girl can, and the knife edge of a blade of grass would cut its head right off if it weren't for this saddle. See, here are its long leaping-legs, and on the back edge of these are some spines to keep it from slipping, and the feet are padded with several soft little cushions that keep it from chin-chopping itself to pieces when it lands after a long jump. And here, my dear, are little rest-legs just behind the front legs. With these Mr. Locust hangs on to a blade of grass when tired--a fine idea, child; every little boy and girl ought to have some rest-legs like the locust. And the locust has some extra eyes, too." Ben Gile was going so fast now that Betty was listening to him, mouth open, as he pointed with a blade of grass to one thing after another.
