There was another general rush, to look through the tubes, and the Pavilion rang with shouts of delight, through which the Professor’s anxious tones could scarcely be heard. “Keep the door of the Microscope _shut_!” he cried. “If the creature were to escape, _this size_, it would——” But the mischief was done. The door had swung open, and in another moment the Monster had got out, and was trampling down the terrified, shrieking spectators. But the Professor’s presence of mind did not desert him. “Undraw those curtains!” he shouted. It was done. The Monster gathered its legs together, and in one tremendous bound vanished into the sky. “Where _is_ it?” said the Emperor, rubbing his eyes. “In the next Province, I fancy,” the Professor replied. “That jump would take it at _least_ five miles! The next thing is to explain a Process or two. But I find there is hardly room enough to operate—the smaller animal is rather in my way——” “Who does he mean?” Bruno whispered to Sylvie. “He means _you_!” Sylvie whispered back. “Hush!” “Be kind enough to move—angularly—to _this_ corner,” the Professor said, addressing himself to Bruno. Bruno hastily moved his chair in the direction indicated. “Did I move angrily enough?” he inquired. But the Professor was once more absorbed in his Lecture, which he was reading from his note-book. “I will now explain the Process of—the name is blotted, I’m sorry to say. It will be illustrated by a number of—of——” here he examined the page for some time, and at last said “It seems to be either ‘Experiments’ or ‘Specimens’——” “Let it be _Experiments_,” said the Emperor. “We’ve seen plenty of _Specimens_.” “Certainly, certainly!” the Professor assented. “We will have some Experiments.” “May _I_ do them?” Bruno eagerly asked. “Oh dear no!” The Professor looked dismayed. “I really don’t know what would happen if _you_ did them!” “Nor nobody doosn’t know what’ll happen if _oo_ doos them!” Bruno retorted. “Our First Experiment requires a Machine. It has two knobs—only _two_—you can count them, if you like.” The Head-Cook stepped forwards, counted them, and retired satisfied. “Now you _might_ press those two knobs together—but that’s not the way to do it. Or you _might_ turn the Machine upside-down—but _that’s_ not the way to do it!” “What _are_ the way to do it?” said Bruno, who was listening very attentively. The Professor smiled benignantly. “Ah, yes!” he said, in a voice like the heading of a chapter. “The Way To Do It! Permit me!” and in a moment he had whisked Bruno upon the table. “I divide my subject,” he began, “into three parts——” “I think I’ll get down!” Bruno whispered to Sylvie. “It aren’t nice to be divided!” “He hasn’t got a knife, silly boy!” Sylvie whispered in reply. “Stand still! You’ll break all the bottles!”
