“The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. And I knew we’d get into that rotten stuff pretty soon. Probably at the next gas station. We had sampled almost everything else, and now— yes, it was time for a long snort of ether. And then do the next hundred miles in a horrible, slobbering sort of spastic stupor. The only way to keep alert on ether is to do up a lot of amyls—not all at once, but steadily, just enough to maintain the focus at ninety miles an hour through Barstow.”
