As more people settled in the valleys, there was an inevitable overlapping of claims. The settlers claimed both the water and the land, and they had government deeds to back them up in their claims. But the beaver had prior rights, and gamely adhered to them. A feud arose that is still unsettled between the Old Settlers and the newcomers. In my rambles I continually came upon homesteaders striving to drain the valleys and raise grass for their cattle, while simultaneously the beavers were working to maintain high water. Many of them lost their lives for their cause, but rarely did they forsake a home site once established. In the same sections, where the homesteaders had used aspen for their fence posts, the beavers, no doubt mistaking them for trees, cut them down. Sometimes their pluck and persistence won them the admiration of their enemies. In most cases they won out. One day, far up near the headwaters of the Cache la Podre River in Colorado, I came upon a rancher trying to drain a number of beaver ponds to secure water for irrigation; it was a very dry season and water was scarce. During the day he tore gaps in the dams, during the night the beavers repaired the breaks. When after opening the dams the rancher hurried down to his fields to regulate the flow of water, the beavers, even in the daytime, would swarm forth and plug up the holes. Finally in desperation, the man set traps in the gaps he had opened in the dams. He caught a few beavers and decided that his troubles were over. But the survivors met the emergency. They floated material down from above and wedged it into the breaks, without going near the traps. At this stage of the struggle an old prospector came down from the higher mountains, driving his burros ahead of him. Hearing of the rancher's predicament, he suggested his own panacea for all troubles, dynamite. Enthusiastically, the rancher accepted his proposal. Soon the dams were in ruins. A mile below where the dams had been destroyed an irrigation ditch tapped the river and carried a full head to the green fields. I saw the rancher standing in the middle of the field, water flowing all about him. He looked upstream and chuckled, then leaned triumphantly on his shovel handle. For a long time, he leaned thus, lost in dreams of prosperity. Suddenly he awoke and hurried along his supply ditch. Barely a trickle was coming down it. The beavers had dammed the intake. I once worked for a rancher who had a homestead on the North Fork of the St. Vrain River, which heads south of Long's Peak. He had just finished clearing a patch of ground to raise "truck" on. "We've got to get rid of some beaver," he told me the very first day. He shouldered his shovel and walked down to the dam that sprawled across the meadow for several hundred feet. "I cut her loose," he informed me on his return. "She'll soon dry out so we can put in the crop."
