"Well, you might try a little surface or placer mining," replied Gabe. "That looks like a good place to dig," he went on, pointing to a gravelly spot, about a hundred feet from where he had decided to pitch the tent. "You boys can be miners for a while until I get camp in shape. But don't be disappointed." Eagerly unpacking their picks, shovels and washing pans, the boys hurried over to where the old miner had indicated. As the method they were about to use may not be familiar to all of my readers I will briefly describe it. The kind of gold they hoped to find is known as free gold--that is, it exists in little grains, sometimes only as large as a pin point or a pin head, and, again, the size of a walnut. It is mixed in with the dirt or gravel, and is usually washed to its resting place by some flood. Other gold is held in ores, or hard rocks, which must be crushed and specially treated before the precious metal can be extracted. The kind of mining the boys were about to undertake is very simple. Acting under Gabe's advice, they first loosened the top soil with their picks. This they threw aside, as it was not very likely to contain gold, which, being quite heavy, would be washed by the rains below the surface. After digging down a little way, the boys came to some fine gravel. This, Gabe had told them, might contain fine grains of gold, but to determine that point they had to wash the dirt. For this purpose the simplest means are common iron pans, circular and rather shallow. Another method is by a wooden "rocker," which will be explained later. Filling their pans half full of the gravel, the boys let water run in from a near-by mountain stream. They now had a mixture of very moist mud. This they agitated in the pans by a peculiar circular motion, the object of it being to cause the heavier grains of gold to sink to the bottom of the pan. Repeated applications of water, and shakings of their pans, soon washed out most of the gravel in the pans, which were tilted at a slight angle to permit this. At length there was only a little fine dirt left in the bottom of the pan. "I think I see something yellow!" exclaimed Jed, greatly excited. "Don't think--make sure," called Gabe. "Here, I'll do it for you." He was almost as excited as the boys. The gold fever was on him again. Taking Jed's pan, he let some more water run in it. Then with a gentle whirling motion he threw this water out by degrees, the fine sand and gravel going with it. Then there remained in the bottom of the pan a little heap of glittering yellow grains. "Gold! It's gold!" murmured Gabe. "Boys, we've struck our first pay dirt!" [Illustration: "Gold! It's gold!" murmured Gabe] CHAPTER XVI LOST "Hurrah!" yelled Jed, capering about. "We're in luck! Gold, Will! What'd I tell you? I knew we'd find it!" and he began dancing about like an Indian, or a cowboy celebrating a holiday.
