In each case he took two buckets full of gravel, poured them out onto a tarpaulin, and coned and quartered. This is a process of sample-taking. He piled the gravel into a cone, then quartered it with a shovel blade, took the two opposite quarters of his choice, remixed them, and made another cone. Then he quartered that one, working down till he had a cross-section of the sample weighing two to three pounds. Then this went into a polyethylene-lined canvas bag after drying; the bag was sealed and carefully labeled. In a month he had fifteen hundred pounds of sand and gravel in six hundred bags from the beds of the seventy streams. Then he started on the mountain itself.
He already believed his sacks of gravel would prove to contain, under laboratory examination, quantities of alluvial tin, minute particles washed down from the mountain over tens of thousands of years, showing that there was cassiterite, or tin ore, buried in the Crystal Mountain.
He divided the mountain faces into sections, seeking to identify the birthplaces of the streams and the rock faces that fed them in the wet season. By the end of the week he knew there was no mother lode of tin inside the rock, but suspected what geologists called a disseminated deposit. The signs of mineralization were everywhere. Beneath the trailing tendrils of vegetation he found faces of rock shot through with stringers, half-inch-wide veins like the capillaries in a drinker’s nose, of milky-white quartz, lacing yard after yard of bare rock face.
Everything he saw about him said “tin.” He went right around the mountain again three times, and his observations confirmed the disseminated deposit, the ever-present stringers of white in the dark gray rock. With hammer and chisel he smashed holes deep in the rock, and the picture was still the same. Sometimes he thought he saw dark blurs in the quartz, confirming the presence of tin.
Then he began chipping in earnest, marking his progress as he went. He took samples of the pure white stringers of quartz, and to be on the safe side he also took samples of the country rock, the rock between the veins. Three months after he had entered the primeval forest east of the mountains, he was finished. He had another fifteen hundred pounds of rock to carry back to the coast with him. The whole ton and a half of rock and alluvial samples had been carried in portions every three days back from his working camp to the mam camp, where he now lay waiting for dawn, and stacked in cones under tarpaulins.
After coffee and breakfast the bearers, whose terms he had negotiated the previous day, would come from the village and carry his trophies back to the track that called itself a road and linked the hinterland with the coast. There, in a roadside village, lay his two-ton truck, immobilized by the absence of the key and distributor rotor that lay in his knapsack. It should still work, if the natives had not hacked it to bits. He had paid the village chief enough to look after it. With his samples aboard the truck and twenty porters walking ahead to pull the lurching vehicle up the gradients and out of the ditches, he would be back in the capital in three days. After a cable to London, he would have, to wait several days for the company’s chartered ship to come and take him off. He would have preferred to turn north at the coast highway and drive the extra hundred miles into the neighboring republic, where there was a good airport, and freight his samples home. But the agreement between ManCon and the Zangaran government specified that he would take them back to the capital.
Jack Mulrooney heaved himself out of his cot, swung aside the netting, and roared at his cook, “Hey, Dinga-ling, where’s my bloody coffee?”
The Vindu cook, who did not understand a word except “coffee,” grinned from beside the fire and waved happily. Mulrooney strode across the clearing toward his canvas washbucket and began scratching as the mosquitoes descended on his sweating torso.
“Bloody Africa,” he muttered as he doused his face. But he was content that morning. He was convinced he had found both alluvial tin and tin-bearing rock. The only question was how much tin per rock-ton. With tin standing at about $3300 per ton, it would be up to the analysts and mining economists to work out if the quantity of tin per ton of rock merited establishing a mining camp with its complex machinery and teams of workers, not to mention improved access to the coast by a narrow-gauge railway that would have to be built from scratch. And it was certainly a godforsaken and inaccessible place. As usual, everything would be worked out, taken up or thrown away, on the basis of pounds, shillings, and pence. That was the way of the world. He slapped another mosquito off his upper arm and pulled on his T-shirt.
Six days later Jack Mulrooney leaned over the rail of a small coaster chartered by his company and spat over the side as the coast of Zangaro slid away.
“Bloody bastards,” he muttered savagely. He carried a series of livid bruises about his chest and back, and a raw graze down one cheek, the outcome of swinging rifle butts when the troops had raided the hotel.
It had taken him two days to bring his samples from the deep bush to the track, and another grunting, sweating day and night to haul the truck along the pitted and rutted earth road from the interior to the coast. In the wet he would never have made it, and in the dry season, which had another month to run, the concrete-hard mud ridges had nearly smashed the Mercedes to pieces. Three days earlier he had paid and dismissed his Vindu workers and trundled the creaking truck down the last stretch to the blacktop road which started only fourteen miles from the capital. From there it had been an hour to the city and the hotel.
Not that “hotel” was the right word. Since independence, the town’s main hostelry had degenerated into a flophouse, but it had a parking lot, and here he had parked and locked the truck, then sent his cable. He had only just been in time. Six hours after he sent it, all hell broke loose, and the port, airport, and all other communications had been closed by order of the President.
The first he had known about it was when a group of soldiers, dressed like tramps and wielding rifles by the barrels, had burst into the hotel and started to ransack the rooms. There was no point in asking what they wanted, for they only screamed back in a lingo that meant nothing to him, though he thought he recognized the Vindu dialect he had heard his workers using over the past three months.
Being Mulrooney, he had taken two clubbings from rifle butts, then swung a fist. The blow carried the nearest soldier halfway down the hotel corridor on his back, and the rest of the pack had gone wild. It was only by the grace of God no shots were fired, and also owing to the fact that the soldiers preferred to use their guns as clubs rather than search for complicated mechanisms like triggers and safety catches.
He had been dragged to the nearest police barracks and had been alternately screamed at and ignored in a subterranean cell for two days. He had been lucky. A Swiss businessman, one of the rare foreign visitors to the republic, had witnessed his departure and feared for his life. The man had looked through Mulrooney’s belongings and contacted the Swiss embassy, one of the only six European and North American embassies in the town, and it had contacted ManCon.
Two days later the called-for coaster had arrived from farther up the coast, and the Swiss consul had negotiated Mulrooney’s release. No doubt a bribe had been paid, and no doubt ManCon would foot the bill. Jack Mulrooney was still aggrieved. On release he had found his truck broken open and his samples strewn all over the parking lot. The rocks had all been marked and could be reassembled, but the sand, gravel, and chippings were mixed up. Fortunately each of the split bags, about fifty in all, had half its contents intact, so he had resealed them and taken them to the boat. Even here the customs men, police, and soldiers had searched the boat from stem to stern, screamed and shouted at the crew, and all without saying what they were looking for.
