Farnham’s Freehold By Robert A. Heinlein

“Maybe I see a way to have running water.”

“If we get running water, I guarantee to provide plumbing fixtures.”

“Really, Daddy? I know what I want. In colored tile. Lavender, I think. And with a dressing table built around-”

“Shut up, infant. Yes, Joe?”

“Well, you know those Roman aqueducts. This stream runs uphill that way. I mean it’s higher up that way, so someplace it’s higher than the shelter. As I understand it, Roman aqueducts weren’t pipe, they were open.”

“I see.” Farnham considered it. There was a waterfall a hundred yards upstream. Perhaps above it was high enough.

“But that would mean a lot of masonry, whether dry-stone, or mud mortar. And each arch requires a frame while it’s being built.”

“Couldn’t we just split logs and hollow them out? And support them on other logs?”

“We could.” Hugh thought about it. “There’s an easier way, and one that would kill two birds. Barbara, what sort of country is this?”

“I beg your pardon?”

“You said that this area is at least semitropical. Can you tell what season it is? And what the rest of the year is likely to bring? What I’m driving at is this: Are you going to need irrigation?”

“Good heavens, Hugh, I can’t answer that!”

“You can try.”

“Well-” She looked around. “I doubt if it ever freezes here. If we had water, we might have crops all year. This is not a tropical rain forest, or the undergrowth would be much more dense. It looks like a place with a rainy season and a dry season.”

“Our creek doesn’t go dry; it has lots of fish. Where were you thinking of having your garden?”

“How about this stretch downstream to the south? Several trees should come out, though, and a lot of bushes.”

“Trees and bushes are no problem. Mmm- Joe, let’s take a walk. I’ll carry a rifle, you strap on your forty-five. Girls, don’t dig so much that it topples down on you. We would miss you.”

“Daddy, I was thinking of taking a nap.”

“Good. Think about it while you’re digging.”

Hugh and Joe worked their way upstream. “What are you figuring on, Hugh?”

“A contour-line ditch. We need to lead water to an air vent on the roof. If we can do that, we’ve got it made. A sanitary toilet. Running water for cooking and washing. And for gardening, coming in high enough to channel it wherever Barbara wants it. But the luxury that will mean most to our womenfolk is a bath and kitchen. We’ll clear the tank room and install both.”

“Hugh, I see how you might get water with a ditch. But what about fixtures? You can’t just let water splash down through the roof.”

“I don’t know yet, but we’ll build them. Not a flush toilet, it’s too complex. But a constant-flow toilet, a sort that used to be common aboard warships. It’s a trough with seats. Water runs in one end, out the other. We’ll lead it down the manhole, out the tunnel, and away from the house. Have you seen any clay?”

“There is a clay bank at the stream below the house. Karen complained about how sticky it was. She went upstream to bathe, a sandy spot.” –

“I’ll look at it. If we can bake clay, we can make all sorts of things. A toilet. A sink. Dishes. Tile pipe. Build a kiln out of unbaked clay, use the kiln to bake anything. But clay just makes it easier. Water is the real gold; all civilizations were built on water. Joe, we are about high enough.”

“Maybe a little higher? It would be embarrassing to dig a ditch a couple of hundred yards long-”

“Longer.”

“-or longer, and find that it’s too low and no way to get it up to the roof.”

“Oh, we’ll survey it first.”

“Survey it? Hugh, maybe you didn’t notice but we don’t even have a spirit level. That big smash broke its glasses. And there isn’t even a tripod, much less a transit and all those things.”

“The Egyptians invented surveying with less, Joe. Losing the spirit level doesn’t matter. We’ll build an unsplit level.”
