"Und now I shall bour it into tubes, und see vether vun tube adjacendt to another eggsplodes der secondt tube vhen der virst tube iss--" That was the night Mitkey almost decided to move himself and his family to a more stable abode, one that did not rock and sway and try to turn handsprings on its foundations. But Mitkey didn't move after all, because there were compensations. New mouse-holes all over, and--joy of joy!--a big crack in the back of the refrigerator where the Professor kept, among other things, food. Of course the tubes had been not larger than capillary size, or the house would not have remained around the mouse-holes. And of course Mitkey could not guess what was coming nor understand the Herr Professor's brand of English (nor any other brand of English, for that matter) or he would not have let even a crack in the refrigerator tempt him. The Professor was jubilant that morning. "Der fuel, idt vorks! Der secondt tube, idt did not eggsplode. Und der virst, in _seggtions_, as I had eggspectedt! Und it is more bowerful; there will be blenty of room for der combartment--" Ah, yes, the compartment. That was where Mitkey came in, although even the Professor didn't know it yet. In fact the Professor didn't even know that Mitkey existed. "Und now," he was saying to his favorite listener, "idt is budt a madter of combining der fuel tubes so they work in obbosite bairs. Und then--" That was the moment when the Herr Professor's eyes first fell on Mitkey. Rather, they fell upon a pair of gray whiskers and a black, shiny little nose protruding from a hole in the baseboards. "Vell!" he said, "vot haff ve here! Mitkey Mouse himself! Mitkey, how vould you like to go for a ride, negst veek? Ve shall see." * * * * * That is how it came about that the next time the Professor sent into town for supplies, his order included a mousetrap--not one of the vicious kind that kills, but one of the wire-cage kind. And it had not been set, with cheese, for more than ten minutes before Mitkey's sharp little nose had smelled out that cheese and he had followed his nose into captivity. Not, however, an unpleasant captivity. Mitkey was an honored guest. The cage reposed now on the table at which the Professor did most of his work, and cheese in indigestion-giving abundance was pushed through the bars, and the Professor didn't talk to himself any more. "You see, Mitkey, I vas going to sendt to der laboratory in Hardtford for a vhite mouse, budt vhy should I, mit you here? I am sure you are more soundt und healthy und able to vithstand a long chourney than those laboratory mices. No? Ah, you viggle your viskers und that means yes, no? Und being used to living in dargk holes, you should suffer less than they from glaustrophobia, no?"
