Conrad Starguard - The High-Tech Knight Part 3

"Well, thank you, but I'd hate to impose on a man I've never met. Anyway, there are plenty of people out of work in Cieszyn. I think our best bet would be to go there and put together a construction crew before going to Three Walls."

"Three Walls?"

"I've decided on the name because the valley we'll build in is boxed on three sides by high mountains. G.o.d has built three of our walls. We need only build the fourth."

"A nice thought. Hmm ...at this speed we'll not make Cieszyn by nightfall."

"Right. The girls couldn't stay in the saddle that long anyway. I think we'll call on Sir Miesko and Lady Richeza for the night. There's a stream and a meadow an hour ahead. We'll break there for dinner."

Sir Conrad's language was always colorful. At the meadow, we helped the ladies off their palfreys, unsaddled the mounts, unloaded the mules and hobbled all the animals save Conrad's Anna, who refused it. Conrad treated Anna as an indulgent father treats a favorite daughter, permitting her to race about the woods around the meadow. Only after she had completely circled the meadow twice, once near and once far, did she come in to drink and crop gra.s.s. It was just exuberance on her part, I know, but I had the uncanny feeling that she was searching for possible ambushers.

I turned from these musings expecting to find the ladies preparing dinner, but the fact was that they could barely walk. Conrad himself was busily chopping wood and in a remarkably short time he had a merry fire going. He seemed to be enjoying himself, proud of his woodcraft, and made no suggestion that any should aid him.

Yet seeing him indulge in this woman's work embarra.s.sed the girls such that they limped up and took over the preparation of food from him, which left him free to join me lying on the gra.s.s.

He was silent for a while, so I said, "Share your thoughts, my friend."

"Well, I'm thinking about that coal mine. It's filled with water and we'll need some sort of pump to empty it."

"Another of your windmills?"

"I don't think so. The valley is surrounded by fairly tall mountains with only a small entrance between the two cliffs. There won't be much wind there."

"It sounds easily defended."

"There is that advantage. But pumping that mine is going to be a problem. Wind power is out. There is no stream, so water power is impossible. Animal power?

The area is heavily forested and it will be years before we're self-sufficient in food.

Importing animal feed would be expensive. But, if we have coal, I wonder if we couldn't come up with a crude steam engine. Pistons, cylinders, and high- pressure boilers are well beyond us, but perhaps a condensing steam engine..."

"Sir Conrad, you have lost me again. Please explain how it were possible to raise water with vapors."

"Let's see ...I've explained that matter exists in three phases: solid, liquid, and gas. If you heat a solid enough, it melts. If you heat a liquid enough, it boils."

"That much is obvious."

"Okay. Now ordinarily the gas phase is much larger than the liquid phase. A given amount of material takes up much more room."

"I'll take that on faith."

"You don't have to take it on faith. You have observed it! You've watched a pot boiling. Look there, where the girls are cooking. Steam is going out of the pot, overflowing it. Further, that steam was once water, as, is proved by the way the water level in the pot gets lower as more steam goes out."

"I said I believe you!" I sat bolt upright.

"You said you had faith! What I tell you about science should never be taken on faith! Each and every step should be proved by direct observation. I am trying to teach you how to understand and manipulate the physical universe. I am not trying to teach you a religion! That's not my job!"

"I'm sorry, Sir Conrad. Please continue." He has such a temper! I think he doesn't drink enough wine.

"No, I owe the apology, Sir Vladimir, and in fact there is a certain religious aspect to science. You see, G.o.d made all beings, all things, the whole of existence. He is the Grand Planner, the Master Designer, the Chief Engineer. When we study the world around us, we are studying His works, His thoughts. It's almost blasphemy to ignore that and have faith in the words of a mere man."

I lay back down. "Now, that is a remarkable thought! That it were possible to study the mind of G.o.d by observing His works-in the same manner that I have studied your mind by observing your mills and looms. Incredible! ...I think that it will take me a long time to absorb it."

We were silent for a while and then our ladies called us to dinner. They were still walking stiffly and were not at all cheerful.

"Why such downcast faces?" I asked.

"My love, it is not my face which is troubling me," Annastas.h.i.+a replied.

"Well, cheer up! We shall be at Sir Miesko's in four more hours."

"Four more hours!" came five simultaneous feminine cries.

"Well, I'm sorry," I said. "But there's nothing for it. The fault is all in those sidesaddles you persist in using. With the possible exception of teats on a stallion, they are the stupidest things imaginable. There is nothing to keep the rider in place but the horse's good intentions, an untrustworthy thing at best. Look at that rig! The rider must sling her right knee over a k.n.o.b designed to numb her leg, put her left foot into an inadequate stirrup and then put her right toe under the back of her left knee to obliterate sensation in that member as well. Its sole purpose seems to be to permit a woman to ride while wearing a dress and destroying her body."

"Well ...what are we supposed to do about it?"

"Don't ask me, my love. I am taxed to my abilities being a fighter and a lover. Sir Conrad is our master of technical devices."

Five pairs of eyes turned on Conrad.

"It's obvious. Put on pants and ride on a man's saddle."

"That's scandalous!" Krystyana said. "The very thought that a lady would be seen in a man's clothing..."

"Then there's the key word, pretty girl, 'seen.' Make an outfit that looks like a woman's dress but functions like a man's pants."

"Uh ...I don't follow you."

"Take one of your dresses. Slit it hem to crotch in front and behind. Sew in a fold of cloth between them. If you're careful about it, you can make it look acceptable but still be able to fork a horse."

The girls looked at each other anxiously and then grew a communal grin.

Suddenly, Krystyana said, "But how would you get into it?"

"Well ...you could make it in two pieces, top and bottom, blouse and skirt; or you could slit it down the front and b.u.t.ton it up like one of my s.h.i.+rts."

The grins returned.

"But that's not going to get us to Sir Miesko's. You girls clean and pack the gear while we saddle the horses."

The sun was still high when we arrived. Sir Miesko was out inspecting his fences, but Lady Richeza. greeted us well. She is easily the most courteous and gracious woman in Christendom. She was common-born, like my Annastas.h.i.+a, and seeing her well-run household gave me visions of my own domestic bliss. But Sir Miesko was base-born as well, and knighted on the battlefield for valor. He was not faced with a heroic father and twenty generations of n.o.bility.

Sir Conrad was talking intently with Lady Richeza.

"Yes, Sir Conrad, Gretch arrived safely and the girl's a wonder! This new mathematics of yours is a fascinating thing. I have no doubt that we'll have a dozen good instructresses by Christmas."

"And how about the schools?"

"It goes well. Eight villages are fully committed, and by winter I think that the problem will be the lack of educated teachers."

"A dozen the first year is better than we had hoped. Textbooks?"

"We've made a start, buying supplies out of Cieszyn. But at the rate it's going, we won't have four dozen sets in time."

"That's skinny. Haven't you heard from Father Ignacy?"

"Not yet. But there was a delay in finding a merchant going to Cracow."

"Well, if you don't hear from him in a few weeks, inquire about professional copyists in Cieszyn."

"But that's expensive, Sir Conrad, and we're already close to your budget."

"Well, going over budget is not as bad as blowing the whole project. We need the books."

"Excuse me, Sir Conrad," I interrupted. "What is all this about?"

"Lady Richeza and I are organizing a school system. We'll have a dozen schools going next winter, from Christmas to spring planting."

"Schools? To teach what? To whom? By whom?"

"Schools! Reading, writing, and arithmetic for starters. For Lambert's people. By Lady Richeza's gallant ladies."

"For the peasants? With some peasant women teaching them?"

"Sir Vladimir. May I point out that you show all the signs of being in love with a lowly peasant? That you are under the roof of a man who was born among these unfortunate people? And, while I am at it, that in the long run, the truly important thing is that women bear children and raise them properly-which includes education-and that the best that we males can do is to support them in that function? Now start apologizing and start with Lady Richeza."

d.a.m.n! d.a.m.n and thrice d.a.m.n! But I had sworn to protect the man. Fighting him was out of the question and there was nothing for it but to apologize.

I had only begun when Sir Miesko came in and Conrad called to him.

"Sir Miesko! Say h.e.l.lo to your new neighbor!"

"What? You, Sir Conrad? What is this?"

"Count Lambert has granted me lands adjoining yours."

"Congratulations! But ...that can only be in the hill country. There's not much good farming land up that way."

"True. But I plan to make mortar from limestone and coal, do some lumbering, and perhaps raise some sheep."

"Well, it might work. But how are you going to feed your people?"

"Obviously, I'll have to buy food, which is one of the reasons I wanted to talk to you. I hope to be your best customer. "

"Well, I'd rather sell to you than a Hungarian merchant, but this wants talking. I have a new vat of beer in need of breaching. Let us retire to my chamber."

Lady Richeza was in rapt conversation with Krystyana, with most of the others gathering around. Soon they moved off to the kitchen. I thought I was abandoned, but, no. I had my Annastas.h.i.+a.

Chapter Three.

The next day, on the road to Cieszyn, I said, "Sir Conrad, you were speaking of a machine with vapors..."

"A condensing steam engine. Yes?"

"Tell me the way of it. This is something that you've seen before?"

"Well, I've seen a walking-beam engine in a museum, but what I've seen won't work in our situation. You see there is an existing mine shaft that slopes down at about a forty-five degree angle." Observing my facial expression, he gesticulated, drawing the angle in the air so that I understood. "I don't know how far the shaft is straight, but I think that I have an even simpler mechanism that should work."

"Indeed. I have seen a walking-beam and to my eyes it was no simple thing."

"Have you! Where?"

"At the salt mines near Cracow."

"Sir Vladimir, we are going to have to visit that place. But back to my engine.

Imagine a barrel with two holes in the bottom and one in the top. One of the bottom holes is fitted with a valve that will let water in but not out. It has a long pipe on it that leads down into the water. The other bottom hole has another long pipe on it-say about eight yards long-that leads up to another barrel with another valve on the bottom that lets water in but not out. These valves can be simple pieces of leather that loosely cover a hole."

"I can imagine that."

"Okay. Into the top of each barrel, we run a pipe from a boiler, a big kettle with a good lid. Between the kettle and each barrel we have a valve that is open and shut by hand. Still following me?"

"'Yes."

"Right. Now we open the steam valve which fills the lower barrel with steam. Air in the barrel is forced out into the upper barrel."

"Uh ...oh. You have a fire under the kettle."

"Of course. Now we close the steam valve. Steam in the lower barrel cools, condensing back to water which takes up much less s.p.a.ce than the steam. The valve in the upper barrel will not let air back in so water is sucked up the pipe to fill the lower barrel."

"Uh..."

"Have you ever drunk through a straw?"

"A straw? No, but once when I was ill my mother had me drink hot beer through the shaft of a heron's feather."

"Same thing. As the lower barrel is filling, we purge the top barrel of air as we did the lower barrel. Once the lower barrel is full, we open the bottom steam valve again and close the top one. Thinking about it, these two steam valves could both be worked with the same handle. The water runs out the lower barrel and up to the top one, having been lifted sixteen yards. Closing the steam valve repeats the process."

"Now, I don't know how deep that mine is, but I'm sure it's more than sixteen yards. Still, I see no reason why we can't cascade any number of barrels, each feeding the one above it. We'd only need two steam lines, one for odd barrels and one for even."

"Why, that sounds wondrous, Sir Conrad." We rode a while in silence as I tried to digest it all. Then I said, "But why would you need many barrels? Why not just put a longer pipe on the first one?"
