 PRESCOTT, Dec. S.-"In my ex perience, covering nearly every oil field of this continent, l have never seen any other untested location that presented so many favorable features as this one.'
 This is what R. Ronald Sager, a Standard oil geologist wrote in sum- marking his report on the Chino val ley field, where a boom is now pre- vailing and where a number Of com- panies, chief among which is the New York Chino Valley Oil Syndicate, are making preparations to drill in the im- mediate future. Two companies al- ready have rigs on the way to the field and others are engaging in financial campaigns with the same end in view. Sager who is known from coast to coast as a man whose opinions on oil fields are very much worth while, agrees with Etienne Ritter and other noted geologists who have inspected Chino valley, although he had not seen their reports. Excerpts from his re- port follow:
 T learn that this district has been under favorable consideration for the prospects of oil for a period of about ten years past, and that reports from oil geologists and reputable practical oil men have been more or less favor able to this district. Notable among the geologists who have recently re- ported favorably upon the Chino val lev oil stratification is Dr. Etienne A. Ritter, mining engineer, doctor or sciences, member of the American h. stitute of Mining Engineers and of the Institute of Mining and Metallurgy.
 Tn T. IS N, R. 3 w., there has been a well drilled, reaching a depth of practically 1900 feet. I learned from local history that this well was started a number of years ago by local people and as a result of lack of knowledge of the formation they would be likely to encounter, they were compelled to give up drilling at about 1900 feet. l am satisfied from the statements and data available that the well was drilled through 100 feet of oil sand, and that the showing for paraffin oil of high gravity was remarkably good.
 There is an abundance of evidence in this field of the cretaceous Times, with their various contents, to insure a base from which oil and gas are created. There are many indications of the porous sandstones and shales to collect the oil, and convey same, also the necessary strata of rock to form an impervious or oil-tight cover for oil- bearing sandstones and shales.
 This oil structure is located on an extensive anticline of carboniferous limestone called the Black Forest area. Nearly all the geological formations found there are exposed in the Grand Canyon of the Colorado to the north west, and again in the Jerome mining district to the southeast.
 Tn making an approximate estimate of the thickness of the various forma- tions, one can only try to strike general average of the exposures at the Grand Canyon and Jerome. would estimate that it would be more than 25oO feet to the bottom of the sedimentaries or possible oil forma- tions included in this anticline, prob- ably a considerable less depth.
 The fact that no proven oil well has as yet been discovered in Arizona is no indication that there should not be oil in the state. As I have hereto fore stated the various attempts made to drill have no bearing from the | standpoint of thorough test"
