"Oh, he took it all in with open mouth," chuckled Bud. "Every now and then he'd out with a '_si senor_,' which encouraged Professor Wright to go on." "And how did it end?" asked Dick. "Oh, the prof. kept spouting away for an hour or more, showing bone after bone of some he'd dug up (this was before the present occasion) and when he was all through he leaned back with a jolly satisfied smile on his phiz. "But say, Dick," went on Bud, "I wish yon could have seen the look on the dear old prof.'s face when the Greaser pointed to the bones and grunted out: "'Him good plenty much make soup!'" "No! Really?" "As sure as I can throw a rope! The idea of boiling up the million-year bones to make soup! I sure thought the prof. would die! After that he didn't spout his wise stuff to any more Greasers." "I shouldn't think he would." But on this occasion Professor Wright had a ranch more receptive and intelligent audience. For, as I have said, overhearing Dick and Bud discussing the "jaw-breaking names," as the boys termed them, the scientist approached them with a reassuring smile on his face and said: "You are somewhat like the old lady, told of in the book written by Professor Lucas of the American Museum of Natural History. In his introduction he speaks of the necessity for using what are termed 'big' words--that is scientific terms, and he mentions an old lady who said she wasn't so surprised at the discovery of all these strange animals, as she was at the fact that someone knew their names when they were found." "But you don't know the names when you find them; do you?" asked Dick. "Don't you name them after they are found?" "In a way we do, yes," answered the scientist. "But in the case of those already found--and I am searching for specimens of some extinct animals already identified--we have settled upon names. "As Professor Lucas remarks, the real trouble is that there are no common names for these animals. As a matter of fact, when they existed there were no people on earth to name them, or, if there were, the names given by prehistoric man were not preserved, since they wrote no histories. "And, as a matter of fact, those who complain that these names are hard to pronounce do not stop to think that, in many cases, the names of the Dinosaurs are no harder than others. They are simply less familiar and not so often used. You wouldn't call hippopotamus a hard word; would you, boys?" he asked. "It isn't hard to pronounce, but I'd hate to have to spell it," chuckled Bud. "It's easy if you take it slow," declared Dick, and, then and there he spelled it. "Well, you've been to more circuses than I have," countered Bud.
