Freckles's dad, that everyone calls Doc Watson, is a pretty good fellow for a human, and he doesn't mind you hanging around the store if you don't drag bones in or scratch too many fleas off. So I'm there considerable in right hot weather. Under the soda water counter is the coolest place for a dog in the whole town. There's a zinc tub under there always full of water, where Doc washes the soda-water glasses, and there's always considerable water slopped on to the floor. It's damp and dark there always. Outdoors it may be so hot in the sun that your tongue hangs out of you so far you tangle your feet in it, but in under there you can lie comfortable and snooze, and when you wake up and want a drink there's the tub with the glasses in it. And flies don't bother you because they stay on top of the counter where soda water has been spilled. Circus day was a hot one, and I must have drowsed off pretty quick after lying down. I don't know how long I slept, but when I waked up it was with a start, for something important was going on outside in Main Street. I could hear people screaming and swearing and running along the wooden sidewalk, and horses whinnying, and dogs barking, and old Si Emery, the city marshal, was yelling out that he was an officer of the law, and the steam whistle on the flour mill was blowing. And it all seemed to be right in front of our store. I was thinking I'd better go out and see about it, when the screen doors crashed like a runaway horse had come through them, and the next minute a big yellow dog was back of the counter, trying to scrouch down and scrooge under it like he was scared and was hiding. He backed me into the corner without seeing me or knowing I was there, and like to have squashed me. No dog--and it never struck me that maybe this wasn't a dog--no dog can just calmly sit down on me like that when I'm waking up from a nap, and get away with it, no matter _how_ big he is, and in spite of the darkness under there I could see and feel that this was the biggest dog in the world. I had been dreaming I was in a fight, anyhow, when he crowded in there with his hindquarters on top of me, and I bit him on the hind leg. When I bit him he let out a noise like a thrashing machine starting up. It wasn't a bark. Nothing but the end of the world coming could bark like that. It was a noise more like I heard one time when the boys dared Freckles to lie down between the cattle guards on the railroad track and let a train run over him about a foot above his head, and I laid down there with him and it nearly deefened both of us. When he let out that noise I says to myself, “Great guns! What kind of a dog have I bit?”
