REPORT 0F OIL EXPERT

In response to a request of the Yu- ma Commercial Club one of the most progressive business organizations in the territory, r. l.. Griffin, an oil ex- pert of many years successful eX- peience in locating profitable oil fields has prepared report on the oil fields of northern Arizona, copy of which was received by the Phoenix Board of Fade yesterday.
 Because the matter of developing oil in Arizona is of paramount inn portance to all sections of the terri tory. no matter where the oil may be found in paying quantities. the in formation contained in MT. Griffin's report will be read with interest all over Arizona. Such a development of oil would mean the investment of many millions in the territory.
 The report in part is as follows:
 My examination extended over a period of some five days on the ground, and was confined to that sec tion East of the Verde river and op- posite to the town of Jerome, and south below Camp Verde. and east ward in many places from seven to fifteen miles.
 Having examined in times past many sections of the great Colorado River Plateau country. with it's un- rivalled sand stone formations. and its conditions favorable for local oil districts or fields, especially those of the San Juan region of Utah, being just over the northern boundary of Arizona, and situated about one hundred and seventy five miles north of the Verde region; it was no stretch of the imagination to connect the Verde field with this great az gregate formation, as the southern extension of the great San Juan oil field.
 Using the Verde River as a di- vissional line, the formation changes from an igneous one on the west to d sedimentary formation on the east, and a sedimentary formation is the first requisite for an oil field or belt
 This formation consists of large measures of sand stone. lime, and shale being also the usual forma- tions encountered in any oil field The tertiary formation in which the oil measures of Gala are found. are here entirely eroded away and an older formation, the cretaceous is eX posed to view; in this, you may expect to develop a grade of refining oil much superior to the California pro duct
 The age then geolOgically of the formation to the east of the Verde river is favorable for oil, and the quality should be good.
 "One of the prime conditions neces- sary to make an oil field possible. in any formation, is. how it lies to the world.
 "All sedimentary formations have been built by sea action, and were necessarily built up stratum by stat um, lying parallel and level. Before a commercial oil district could be a possibility, ages must elapse, these thousands of feet in depth must needs have been elevated by a pressure from beneath, from the position of a level, to one known as 'anti-clines. and mono-clines," the surface per chance may become a forest, grass land, or later. improved farms.
 With the lapse of vast periods of time the oil that may have been generated in and under millions of acres of land is driven and gathered in certain belts in accordance with the lay of the land as it has been changed from the position of level to that of an incline.
 "The man who studies and detects the favorable places for an oil field does not need to be a college, nor a technical man; but he should be familiar with formations and the nec- essary requirements to detect where the drill should be used to test out those favorable places.
 Coming to the point of an abso- lute test, there is not a geologist in the world that can tell for certain that any given spot in an unproven field will result in oil being devel- oped.
 ''The drill is the only absolute test; The value of an expert so called, IS that, if he understands his business. he can be of great assistance in both determining the probability of oil. and also can select the more likely place to make the test.
 "There are many things that, com bined. assist one to a determination as to whether any certain section is or is not favorable for oil. only few of these can be stated in a letter, but desire to to write as to give as much informntion as possible to those who
