junction of the Marmaton, and not simply the stream in its 
present restriction. 
Omitting the bottom shales, there can be no doubt as to the 
Well Rock series representing what we now call the Bethany 
limestone. The evidence offered by the Miami county section 
is conclusive. Moreover, the thickness given is only about 
three feet greater than is now generally ascribed to the Beth- 
any of this region. The correlations are in the main wrong. 
It is clearly shown that he mistook the Plattsmouth limestones 
at Lawrence and Leavenworth for the terrane in question. 
Swallow's Spring Rock series, together with the local sand- 
stone is so clearly the exact equivalent of the Thayer shales 
that no question can arise as to the identification. The thick- 
ness, however, was estimated to be over double what it really 
is. Neither is there an}- doubt about the Cave limestone being 
the same as the lola. In Miami county its maximum thick- 
ness is placed at 30 feet, which is the same as recorded for the 
lola a little farther north at Kansas City. 
As for the Stanton limestone, which is named after the 
town of that title in the western part of Miami county, it is 
unquestionably the same as the Garnett of later Kansas 
writers, or the lower member of Broadhead's Plattsburg. The 
lower shaley portion of the Stanton Limestone series cor- 
responds to the Parkville shales, and has ascribed to it about 
the same thickness as is known farther north on the Missouri 
river. The correlation made by Swallow of the Stanton 
limestone, as developed in the original locality on the Marais 
des Cygnes river, and that stratum of the same title in the sec- 
tion west of Topeka is of course erroneous, for it is now 
known that there is a stratigraphical interval between the two 
localities of more than 500 feet which is occupied by the Law- 
rence shales, Plattsmouth limestones, Platte shales and the 
Forbes (Burlingame?) limestone. 
Prosser makes the statement"-^' that Wabaunsee formation 
extends upward from Swallow's No. 154, which is a few feet 
beneath the "Stanton limestone." This cannot, of course, refer 
to the section containing the typical Stanton limestone, but to 
its supposed representative in central Kansas, which is a very 
different thing.
