Those old cows knew trouble was coming before we did. It was late on an August afternoon, the air hot and heavy like it usually was in the rainy season. Earlier we'd seen some thunderheads near the Burnt Spring Hills, but they d passed way up to the north. Fd mostly finished my chores for the day and was heading down to the pasture with my brother, Buster, and my sister, Helen, to bring the cows in for their milking. But when we got there, those girls were acting all bothered. Instead of milling around at the gate, like they usually did at milking time, they were standing stiff$-$legged and straight$-$talled, twitching their heads around, listening. Buster and Helen looked up at me$,$ and without a word, I knelt down and pressed my ear to the hard$-$packed dirt. There was a rumbling, so faint and so low that you felt it more than you heard it$.$ Then I knew what the cows knew$-$a flash flood was coming.
