Grady Coa/.— The lowest coals found through the Cherokee and 

 Creek Nations will be discussed under this heading, though it is 

 doubtful whether they represent the northern continuation of the 

 Grady bed, or whether they all belong to the same bed. The 

 northern and eastern limit of the Cavaniol group, as outlined on 

 the accompanying map, shows the approximate outcrop of this coal 

 bed. The following local developments were seen : About one 

 mile east of Little Salisaw creek, and one-fourth of a mile south of 

 the Kansas City, Pittsburgh & Gulf Railroad, this bed of coal outcrops 

 and has been worked to some extent by stripping. The coal is said 

 to be one and a half feet thick and of good quality. The strata 

 overlying the bed dip 15° to 20° north-northwest. About three 

 miles southwest of Salisaw Station the same coal outcrops along 

 Coal creek. It is one to one and a half feet thick, and has 

 been mined by stripping. This coal was, in the summer of 1896, 

 being used by blacksmiths in Salisaw, who pronounce it an excellent 

 one for their work. The mines were all filled with water at the 

 time the writer visited the place. Along the south side of Spaniard 

 creek, at the Weber's Falls-Muscogee road crossing, the coal bed 

 is ten to twelve inches thick and is mined for local demands. The 

 bed dips north-northwest about 12°. Going from this point toward 

 Muscogee, the synclinal basin is crossed at right angles and the coal 

 outcrop is again seen about four miles southeast of Muscogee. The 

 eastern end of this synclinal fold lies near Braggs, where the bed 

 has been worked a little. It outcrops along branches about two 

 miles south of Braggs, and is four to six inches thick. It is said to 

 underlie Braggs at an average depth of about thirty feet and is six 

 inches thick. Five miles west of Muscogee and one mile south 

 of the Arkansas river, this coal has been worked a little. At 

 that place the coal is eight to twelve inches thick. It outcrops 

 again four miles north-northwest of Adair, along the side of an 

 east-facing escarpment. Where it was seen (the Ross coal bank), 

 the coal is seventeen inches thick, underlies a gray shale and is 

 apparently rather high in ash and sulphur. 



This coal outcrops along Log Cabin creek, about three miles 

 west of Welch, where it is said to be about two feet thick, and is 

 mined for local demands. 



McAlester Coal Bed. — This coal outcrop is approximately located 

 on the map from near Starvilla to Dirty or Elk creek, northeast of 

 Checotah. One and a half miles northwest of Starvilla the coal
