After Palm Springs, the land flattened and the color faded from the landscape. For mile after mile, there was only sand and rock, chaparral, power lines, and passing cars. On either side of the road, at the horizon, the land rose to a fringe of foothills that confined the view. Everything was beige and gray and a pale dusty green. California deserts consist, in the main, of pale soils-fawn, cinnamon, sepia, and pink. We passed the state prison, its presence underlined by signs that advised us not to pick up hitchhikers. The speed limit was seventy, but the landscape was so vast that we scarcely seemed to move. Aside from the Salton Sea to the south of us, the map showed only dry lakes.

I said, "How does anything manage to grow out here?"

Dolan smiled. "The desert's a marvel of adaptability. California desert has one rainy season where southern Arizona has two. The rest of the year, you have drought. If you had seeds that germinated right after the rains, the young plants wouldn't survive the hard sun and heat. Lot of seeds are covered with wax that prevents them from absorbing water until a period of time has passed. Once the wax wears off, they germinate, and that's where the food chain originates. Rabbits and desert rats turn the vegetation into animal flesh and that provides dinner for the predators. Snakes eat the rodents and then the bobcats eat snakes."

"Very nice," I said.

"Efficient. Like crime. Everybody's busy eating someone else."

I He went on in this fashion, regaling me with the mating and egg laying habits of various desert insects, including the black widow, the brown widow, and the tarantula hawk, until I sang, "I'm getting sick here." That shut him up.
