information and clicked. Suddenly a red blinking light appeared on the map of the island. It was north of the limestone escarpment but south of the stream that had been humorously dubbed Rio Diviso. The stream bisected the six-by-two-mile island lengthwise, flowing east to west. In the center of the island was a pond they'd called Lago Hippo for obvious reasons.
"Pretty slick, huh?" Bertram said proudly. Kevin was captivated. It wasn't so much by the technology, although that interested him. It was more because the red light was blinking exactly where he would have imagined the smoke to have been coming from.
Bertram got up and pulled open a file drawer. It was filled with small handheld electronic devices that looked like miniature notepads with small LCD screens. An extendable antenna protruded from each. "These work in a similar fashion," Bertram said. He handed one to Kevin. "We call them locators. Of course, they are portable and can be taken into the field. It makes retrieval a snap compared to the struggles we had initially."
Kevin played with the keyboard. With Bertram's help, he soon had the island graphic with the red blinking light displayed. Bertram showed how to go from successive maps with smaller and smaller scales until the entire screen represented a square fifty feet by fifty feet. "Once you are that close, you use this," Bertram said. He handed Kevin an instrument that looked like a flashlight with a keypad. "On this you type in the same information. What it does is function as a directional beacon. It pings louder the closer it comes to pointing at the animal you're looking for. When there is a clear visual sighting, it emits a continuous sound. Then all you have to do is use the dart gun." "How does this tracking system operate?" Kevin asked. Having been immersed in the biomolecular aspects of the project, he'd not paid any attention to the logistics. He'd toured the island five years previously at the commencement of the venture, but that had been it. He'd never inquired about the nuts

and bolts of everyday operation.
"It's a satellite system," Bertram said. "I don't pretend to know the details. Of course each animal has a small microchip with a long-lasting nickel cadmium battery embedded just under the derma. The afferent signal from the microchip is minuscule, but it's picked up by the grid, magnified, and transmitted by microwave."
Kevin started to give the devices back to Bertram, but Bertram waved them away. "Keep them," he said. "We've got plenty of others."
"But I don't need them," Kevin protested. "Come on, Kevin," Bertram chided playfully while thumping Kevin on the back. The blow was hard enough to knock Kevin forward. "Loosen up! You're much too serious." Bertram sat at his desk, picked up his phone messages, and absently began to arrange them in order of importance. Kevin glanced at the electronic devices in his hands and wondered what he'd do with them. They were obviously costly instruments.
"What was it about your project that you wanted to discuss with me?" Bertram asked. He looked up from his phone messages. "People are always complaining I don't allow them to get a word in edgewise. What's on your mind?"
"I'm concerned," Kevin stammered.
"About what?" Bertram asked. "Things couldn't be going any better." "I've seen the smoke again," Kevin managed. "What? You mean like that wisp of smoke you mentioned to me last week?" Bertram asked. "Exactly," Kevin said. "And from the same spot on the island." "Ah, it's nothing," Bertram declared, with a wave of his hand. "We've been having electrical storms just about every other night. Lightning starts fires; everybody knows that." "As wet as everything is?" Kevin said. "I thought lightning starts fires in savannas during the dry season, not in dank, equatorial rain forests."
"Lightning can start a fire anyplace," Bertram said. "Think of the heat it generates. Remember, thunder is nothing but expansion of air from the heat. It's unbelievable."
