Mr. Livermore has been a resident of California nearly thirty years, and, having married into one of the wealthy families of the country, is the proprietor of some of the best lands for tillage and grazing. An arroyo, or small rivulet fed by springs, runs through his rancho, in such a course that, if expedient, he could, without much expense, irrigate one or two thousand acres. Irrigation in this part of California, however, seems to be entirely unnecessary for the production of wheat or any of the small grains. To produce maize, potatoes, and garden vegetables, irrigation is indispensable. Mr. Livermore has on his rancho about 3500 head of cattle. His horses, during the late disturbances, have nearly all been driven off or stolen by the Indians.
