The base of the formation was not seen in the interior region. The thickness 

 of the formation, consequently, was not ascertained. The sandstone 

 series was found to be extremely fossiliferous, and in it the fossils are 

 beautifully preserved. Fossils were found at two horizons — in the 

 north bank of the Bogachiel river in a bluish-gray rock in section 22, 

 township 28 north, range 14 west of the Willamette meridian, and in 

 the bluff south of the abandoned channel of Ma.vfield creek on the south 

 side of the Bogachiel river, in sections 28 and 29 of the township and 

 range above. But fossils were obtained only from the latter location, 

 as the former was below the surface of the water of the river at the 

 time visited. Below is a description of the fossils obtained. 



"Fossils of the Quillayute Formation (Lower? Pliocene) Exposed in 

 the \'icinity of Quillayute, Wash." [There follows a two-page compari- 

 son of the Quillayute formation fossils with the fossils of other regions, 

 with the final conclusion, page 205, that:] "Consequently, this [the 

 comparison-results] would seem to place the formation at the bottom 

 of the Pliocene. Following is a description of the fossils." [Here follow 

 twenty-two pages — from pages 205 to 226 — describing the fossils of the 

 Quillayute formation.] 



I am unable to find anything in my article that states that 

 the Quillayute fossils described by me were found in a Devil 

 Club swamp or that they were found in glacial drift. More- 

 over, on page 589 (of the cited article) Messrs. Arnold and 

 Hannibal state that the Empire formation in the Empire dis- 

 trict, Oregon, is composed of "about 500 feet of beds, sand- 

 stones at the base, grading upward into massive shales, 

 partially organic in character." 



To quote from my article, paragraph on the Quillayute 

 formation above mentioned (page 203) : "In the interior re- 

 gion, where exposed along the Bogachiel river, it (the Quil- 

 layute formation) is composed of sandstone and bluish-gray 

 shale ; the coast exposures are all conglomerates or a coarse 

 gravelly rock resting unconformably upon the older rocks 

 exposed here." 



My description, accompanied by the description of fossils 

 obtained, shows conclusively that the Quillayute formation is 

 a tN-pical Empire sandstone and shale.
