But it was Johnny’s first creation, the Amazing Toddy Machine, which was the most famous and enduring. Although very few people actually saw it, its reputation was widespread, and its products enjoyed even farther afield. At the heart of this new invention was a large glass tank in which the various raw components were mixed. Everything could be seen clearly in this tank — the initial chemical reaction, the colour, the consistency — and regulating the process was made easier. Nothing was left to chance. The transparency of the machine allowed the brewer to intervene if he thought something was going wrong. The tank was sealed, so any impurities (not to mention animals) could not find their way in. As the system grew, Johnny found a way of increasing the output dramatically — more glass tubes were attached, linking more tanks together, all bubbling away at various stages of ferment. At some point a distillation mechanism was added, ensuring the final product was as clear and smooth as spring water. For a while, purely as a novelty, the toddy was filtered through layers of mangrove wood charcoal, drip by slow drip. People were puzzled by the taste of this, but fascinated too, and soon even more glass tubes and tanks were added. At its height, the machine was said to have resembled a tiny crystal mountain, sparkling with a life of its own.
Johnny’s gift for machines has always been evident to me. Even as a young child, I knew that while other people could perhaps take apart a car engine and then reassemble it, not everyone could do it as Johnny could. It wasn’t so much what he did but how he did it — steadily and gently, with a rhythm all his own. The parts of the engine fell away into his hands like pieces of silk; he held greasy steel bolts the way you or I might hold a newborn chick. I used to watch him fixing things. Whenever he repaired a clock — that was my favourite. His short peasant’s fingers, clumsy in every other way, would suddenly move with all the delicacy of a silk weaver’s. Where other men might have used tweezers or screwdrivers or other tools, Johnny seemed only to use his fingers, touching each part of the clockwork. I always pretended to be doing something else — passing through the room or reading a book. He never knew I was watching.
THE TODDY MACHINE was the beginning of a particular episode in Johnny’s life that goes something like this: Armed with this gift, this knowledge of machines, Johnny becomes well known. People all over the Valley hear about the toddy, they hear about the young man who made it. The mines need people to work in them, but these are hard times for the Chinese mines. They have been in the Valley for fifty, sixty years, since long before the railway was built between Port Weld and Butterworth. They are big, open-cast mines with old-fashioned gravel pumps. But it is not good for them now, because new mines have opened all over the Valley. British mines.
What makes these British mines different is that they do not need many hundreds of coolies to work in them. This is because they have, at the heart of the mine, a mechanised colossus never seen before in these parts. It is called a Dredging Machine, and it does the work of a thousand coolies. It sits astride the mine as the goddess Guan Yin herself sat on a vast lake, floating for all eternity. The Chinese fear this machine, for they do not possess one. The British do not need many men, they simply need a few good ones. Of all the Chinamen in the Valley, only one will be able to understand the Dredging Machine, and it does not take long for the British to learn of his existence.
