Read it through once

And there were little villages, with neat stations well placarded with showy advertisements—mainly of almost too self-righteous brands of “sheepdip.” If that is the name—and I think it is. It is a stuff like tar, and is dabbed on to places where the shearer clips a piece out of the sheep. It bars out the flies, and has healing properties, and a nip to it which makes the sheep skip like the cattle on a thousand hills. It is not good to eat. That is, it is not good to eat except when mixed with railroad coffee. It improves railroad coffee. Without it railroad coffee is too vague. But with it, it is quite assertive and enthusiastic. By itself, railroad coffee is too passive; but sheep-dip makes it wake up and get down to business. I wonder where they get railroad coffee?
