During his residence here he has also paid considerable attention to the citrus culture, having a ranch of 160 acres in Colusa County, where he had at one time a nursery of 5,000 orange trees; but they were destroyed by the rabbit pest two years ago. During the present year (1889) he set out on his land about thirty acres of peaches. He also has ten acres of choice land at the town of Escalante, at the mouth of Capay Valley, which was planted in 1889 to citrus fruits.
