It is probable that these oil-yielding localities have their counter-part in many other places in California, besides those which havebeen mentioned, for the geological formations, constituting these oilmeasures, extend along the Coast Range, from San Diego County toHumboldt County. We have not yet obtained sufficient geological evidence to warrant the expression of anything more than a tentativeopinion, concerning the actual geological horizon of the petroleumformations in the following oil fields: The oil fields on the south sideof the Santa Clara River, those north of Santa Paula, in Ventura.
