The Land of Little Rain

Whatever goes up or comes down the streets of the mountains, water has the right of way; it takes the lowest ground and the shortest passage. Where the rifts are narrow, and some of the Sierra canons are not a stone's throw from wall to wall, the best trail for foot or horse winds considerably above the watercourses; but in a country of cone-bearers there is usually a good strip of swardy sod along the canon floor.
