"What?" yelled the old man. "You dare to invade my grounds and disturb me at my labors for such a reason? Reporters! My scientific research work is not for publicity, sirs; and futhermore I want it understood that I am not to be dragged from my laboratory again for the purpose of entertaining you or any others of your ilk. Get away!" Without further ado the window was slammed down, a shutter closed on the inside, and once more the silence of the dead descended upon the spot. The two men grinned ruefully at each other, Handlon finally breaking the stillness. "My idea of the world's original one-sided conversation. We simply didn't talk--and yet we're supposed to be reporters. You've got to hand it to the Proff, Horace, for the beautiful rock-crusher he just handed us." "You didn't think we had anything easy, did you?" said Perry irritably. "He'll change his tune presently, when--" * * * * * Handlon's jaw dropped. "You don't mean you're going to take any more chances! Would you rouse him again after the way he treated us with that gun? Besides, the train...." Perry bent a scathing glance at his companion. "What on earth has the train to do with our getting the Professor's confession of crime or whatever he has to offer? You evidently don't know Bland--much. I deduce that a lot of my sweetness has been wasted on the desert air. Once more, let me assure you that if you propose to go back without the Proff's mug on one of those plates you might as well mail your resignation from _here_. Get me?" The other wilted. "I wonder," Perry ruminated as he stared in the direction of the shed wherein the canine monstrosity had disappeared. "Do you suppose that you can get a snap of the old boy's mug if I can get him to the window again? If you can do that, just leave the rest to me. I've handled these crusty birds before. What say?" "Go as far as you like." The photographer was once more grinning as he unslung his camera and carefully adjusted a plate in place. Everything at last to his satisfaction he gripped flash pan and bulb. "I'm going to make some racket now," announced Perry grimly. "If Kell shows up, work fast. He may shoot at you, but don't get excited. It's almost dark, so his aim _might_ be poor." At this suggestion his companion showed signs of panic, but the other affected not to notice this. There came a deafening hullaballoo as Perry beat a terrific tattoo on the ancient door. Followed a deep silence, while Perry leaped back to stand in front of Skip and his camera. After perhaps a full minute's wait he once more opened up his bombardment, to jump quickly back to the camera as before. This time he had better success. The window was again opened and the muzzle of the blunderbuss put in its appearance. Handlon stood close behind Perry as he silently swung the camera into a more favorable position for action. The face at the window was purple with wrath.
