There he remained three years, engaged in keeping ranche and trading. Becoming satisfied with his success, he returned home in the fall of 1853 and bought a good farm in Pike county, Illinois, where he lived for a few months, when he again returned to California, remaining one year, when he returned to Pike county again and engaged in the mercantile business in Rockport, in which he continued for two years, and then sold out his store and bought into the Rockport Mills, and has made milling his business ever since. He is now sole proprietor of the celebrated Rockport Mills. This flouring mill is said to be one of the best mills on the military tract, being capable of turning out three hundred and fifty barrels of good flour every twenty-four hours.
