"Ah." Leaton frowned even harder. "Well, to tell you the truth, I've been thinking about organization myself, this last couple of months. Right now we've got everything jumbled up together-splitting up a bit would help, ah, even out the flows all 'round. Save time and effort. For example, we made up the blowers and hearth and so forth for the glassmaking plant, but there's no earthly reason it should be run as part of Seahaven."
"Exactly," Cofflin said, relieved.
Martha nodded. "Wish that glassworks was more useful than it is," she added. "We've got the glass jars, but you need tight lids for heat canning, though, and it's hard to do that without rubber washer rings."
They all sighed agreement. Everyone had gotten extremely sick of salt fish and meat last winter, even if wild greens had kept scurvy and other deficiency diseases at bay. Nobody had wanted to see another piece of dried dulse by spring, either. The icehouses and bigger vegetable crops would help with that this year, and vary the diet, but it would be nice to be able to put up vegetables and fruits in quantity.
"Terri Susman had an idea about that," Leaton said. "She thinks we can reprocess tires to get good-quality sealing rubber. Have to get the steel wire and the cord out, of course, then chop up and reheat the rubber."
"Have her talk to Martha, then," Cofflin said. She was in charge of screening new Town-backed projects. "We should get on to that before summer, when the truck crops start coming in. Plenty of glass jars available now, if we can get the sealing we need."
Martha made a note on a pad she kept with her. "We'll need sulfur to cure raw rubber, won't we?" she said.
Leaton nodded vigorously. "That's getting to be our problem," he said. "Mechanical things, that I and my people can handle. It's chemistry that we're running into bottlenecks with. I could use some sulfuric acid for pickling and cleaning steel, God knows I could, but we can't make it in quantity-and what we do make is cruddy, full of impurities, and the quality is variable as hell. Same with nitric acid. Here, let me show you."
He pulled a scrap of crinkly-looking cotton cloth from a drawer of his desk and put it in a metal pan on the top. Then he took out a fire-starter, snapped it, and dumped the tinder. The cloth went up with a whoosh, a subdued crackling, and a puff of bitter smoke.
"There's our prospect of nitro powder," he said, exasperation in his tone. "If we could do it, we could get blasting explosive and propellants out of sawdust and cloth scraps, anything with cellulose. But we can't. The acid we make's too dirty, and we can't stabilize the results-it goes off if you breathe on it. The chemistry teacher over at the high school, Cynthia Dawes, she's working on it. Probably get it right in a year or two, but it's the old story, not enough people, specialists especially."
. "Plus we have to be careful about by-products," Martha said. "No PCBs or dioxin in the groundwater here, and I'd like to keep it that way."
Both men nodded; Nantucket was a small island, and its water supply was completely dependent on the underground aquifer. Keeping that unpolluted had been hard enough up in the twentieth. The island didn't have that much fresh water to spare in the first place-if you over-pumped the underground supply it got brackish and then salt-and they couldn't possibly let poisons filter down through the sandy soil into the reservoir below.
"Ontogeny recapitulates phylogeny" Leaton said, and Martha nodded. Jared blinked and shrugged; he got the gist, if not the actual reference. "We're redoing the early Industrial Revolution, only we can't afford to make the mistakes they did. Anyway, smokeless powder's out of the question, for a couple of years at least. Black powder we can do-but there the limiting factor's the raw materials. Charcoal is no problem, but we're just now getting significant amounts of saltpeter from the sewage works. And sulfur, well, the nearest accessible sources are down in the Caribbean."
"Through jungle and up volcanoes," Cofflin added. He'd taken a look at the reports. "It's even less popular than the salt-mining detail. Thanks for that mechanical scoop thing, by the way-it's taken a lot of the heartbreak out of that salt collection."
"Plus it's dangerous," Leaton went on. "Making black gunpowder, that is, no way to avoid occasional frictional explosions, that's why Du Pont got out of the business. Once we're up above the couple-of-pounds-a-batch level, I'm going to move we put the plant out by the old airport."
He sighed. "We're doing the best we can with what we've got… I showed you our Hawkeye addition to the ROATS program, didn't I?"
"No, actually," Cofflin said. "With this job and a kid, some details just don't get through. Captain Alston was satisfied, and I took her word for it."
"Ah. Well, come have a look, then."
Cofflin suspected that the machinist just liked an excuse to get out of his office and get his hands on some machinery; but hell, he didn't like sailing a desk much himself. They followed him out into the main shop, and then into the tangle of outdoor projects on the other side of the main building. Leaton dodged into a shed and brought out a weapon, slinging a leather satchel over one shoulder as well.
"Here it is," he said with diffident pride.
"Hmm."
Cofflin hefted the rifle… better check. Yes, spiral grooves down the barrel. Fully stocked in black walnut, looking a little like a hunting rifle except for the hammer and frizzen pan on the side. He swung it up to his shoulder and looked down the barrel; heavier than an M-16, about nine pounds, but well balanced and with a nice solid feel. Mauser-style adjustable sights.
"Feels sweet," he said. "A flintlock, I see."
"Ayup. We've got another model ready to go into production when we finally get the percussion-cap problem licked. We're going to use a tape primer method, like a kid's cap pistol, only using sheet copper instead of paper."
"How's it work?" Cofflin asked.
"Pull the hammer back to half cock," Leaton said. "Then hold the rifle in your left hand and raise that knob along the back of the stock."
"Ah," Cofflin said.
There was a plunger-shaped brass tube bolted to the underside of the section that had swung up, set so that the head of it would slide into the rear of the chamber when the lever was pushed back down.
"Hmm. Will that give you a tight enough gas seal?"
"Nope," Leaton admitted. "Not by itself. And drawn-brass cartridges are not feasible, right now; too big an operation. Here's what we did instead."
He opened the satchel hung over his shoulder and handed the Chief a round of ammunition. The bullet was shaped much like the rifle rounds he was familar with. Not jacketed, though, and it looked like…
"Plain lead?" he said.
"Slightly alloyed with antimony and tin. Ten millimeter, or point-four-inch, if you prefer."
Cofflin snorted, and Martha gave a dry chuckle. The metric-versus-old-style controversy was taking up a lot of time at the more recent Meetings, with the constitution on hold until the expeditionary force in Britain returned. The question of whether or not to hold Daffodil Weekend was a close second.
The rest of the cartridge was paper, and he could feel the black powder crunching within as he rolled it between thumb and forefinger. The rear felt thicker and stiffer.
"Go ahead," Leaton said eagerly. "There's a wad of greased felt at the base of the round. It packs into the gap between the head of the plunger and the chamber under the gas pressure, and seals it-well enough for one use, anyway."
Cofflin slid the cartridge into the chamber with his thumb and snapped the lever back down; an unseen spring held it snugly in its groove atop the rifle's stock. "Ayup, I see," he said admiringly.
"That's really quite clever," Martha said, her tone neutral.
The men both looked at her. She raised a brow and continued: "No, really. I'm just not an enthusiast. Guns are like tractors or can openers to me-tools. It's a gender thing, I think."
