Upon the
 south side of the valley, these veins re- appear, dipping to the north Water
 was struck in the discovery shaft at
 depth of thirty feet.
 Passing down the valley, we ride over
 relatively large tracts of the hornblendic
 rock described above. At point about
 eight miles below the discovery, eX g
 amined an outcrop which showed som
 distance up the south slope Of the val i
 ley. This vein was evidently the base
 of the coal series, and Tas distant about
 one hundred feet perpendicularly from
 the limestone. The dSp of both was
 about 8 degrees to the north In a
 ravine near by, the geological succession
 could be clearly traced. Passing out in-
 to the valley, the debris from disintegra-
 ton of the eruptive rock above has GOV
 cred the original surface. The coal vein mentioned was much decompOsed; but
 I found small seam few feet distant, from which l dug out coal in fair state
 of preservation. This coal appeared to be a typical Ignite, with a clean and glossy fracture, and ignited readily when placed upon a fire, and continued bu urn- ing until reduced to ashes of a grayish color. It did not erumble on exposure to heat. An analysis gave the following result: Volatile cOmbustible matter and water .... .47.B Fixed carbon n...-...----.----.--.- LAO Ash.... . s.4 This analysis evidently approximates the | condition of the coal where it has not | been subjected to extraordinary meta | morphic action, although a better quality | may be expected as depth Is attained. | From this point to the river, coal crop | pings have been found at intervals, but | I have not been able to obtain speci- | mems.
 I was able to obtain no fossils from | the coal series except few imperfect | leaves, which could scarcely be identi- fled. l can therefore offer no evidence | as to the age of the coal itself, except to state that such leaves as 1 noticed ap- peared to resemble those of the Tertiary. From the above observations, and from information derived from others, the following inferences seem warranted: The Deer Creek coal series contains sev- eral veins, at least one of which is of workable size. The original area occu- pied by the series was at least thirty square miles. An unknown proportion of this area has been broken up and rem dered valueless by the destructive action of eruptiye rocks. Where 1t has not been so disturbed, the coal IS Q typical Ignite, with a moderate amount of ash indicated, and of good furnace qualities. Through local metamorphic acton, DOT tiOns of the coal veins have been changed into bituminous coal with cOking quail ties, and even into anthracite, with cor increase of ash. After mak- ing due allowance for surface deteriOra- ton, 1t IS still uncertain whether the lat ter varieties sill be pure enough to be of economic value. Such as 1t is, this coal will be brought into competition with wood of an inferior quality and costing from five to ten dollars a cord, the supply of which Is constantly de- creasing. The coal basin itself contains forests of pinOn, which will furnish good supply of mining timber. It is also centrally located with reference to a large number Ct mining districts, con- taining for the largest part base ores which will require processes involving roasting or smelling, or both. The de- velopment of the cOal-fields has been greatly retarded by the fact that they are, or are said to be, upon the San Car los Indian Reservation; such a condition the securing of titles. It is AAN NO NAiC PtOPAC OA LCAlllolN IAAtil - he Government should have a proper survey made, and decide this question. If the coal-felds are on the reservation, the Government should sanction some I ,ourse by which the coal could be made available for the mining interests of the : vicinity. If it is found to be on the res- srvation, it can be cut off without detri- 1. nent to the same, as it is near its south srn boundary. No agricultural land is involved, and to my knowledge there is not single Indian hut within ten or .welve miles of the valley. Neither the present nor future value of the reserva- ion as a residence for Indians will be 7 impaired by such action. Until some hing is done, capital will decline to un- iertake to make this source of fuel .vailable.
