following year on page 75 of the same publication. This section 
was carefully studied and measured with the Locke level by the 
writer and the result compared with Professor Cragin’s in the fol- 
lowing section. The first column gives Professor Cragin’s numbers, 
the second the thickness as he determined it, and the third the 
writer’s numbers. 
Ajong the Champion draw, a short distance south of Belvidere, 
are fair exposures of the Red Bluff sandstone with numerous large 
spots of greenish-white sandstone in the midst of the red. It is 
very friable, crumbling readily in one’s fingers. At the top of the 
red sandstone are yellowish shales similar to those seen in the 
section of Walker creek, Stokes, and Black Hill. Near the base of 
the Cheyenne sandstone, especially in the bed of the draw are 
efflorescences of sulphur, salt, and other minerals. The Cheyenne 
sandstone is very irregularly bedded at this locality, an excellent 
idea of which is given by the picture of Oross-Bedding in Cheyenne 
sandstone, near Belvidere—Plate X VII—which is a photograph of 
the eastern bank of the Champion draw. The bottom of the picture 
represents the lower part of the Cheyenne sandstone with its layers 
nearly horizontal, while in the upper part of the bluff the beds are 
very much inclined. This portion represents the middle and upper 
parts of the formation. 
No. 5 of Cragin’s Belvidere section, which he has lately named 
the Champion shell-bed is the same stratum as No. 4 of Hill’s sec- 
tion at Stokes’ hill. This stratum weathers to a dirty iron-yellow 
color and contains immense numbers of Gyphaea sheils with other 
fossils, and plenty of gypsum. In some places it is mainly a shell 
rock, containing little gypsum, but composed almost entirely of 
fossil shells. Then comes the black paper shales, above which are 
quite prominent layers containing immense numbers of Cyprimeria 
and J'urritella shells, while the upper part of the hill is composed of 
yellowish argillaceous shales alternating with thin layers of pinkish, 
shaly Ostrea limestone. 
The total thickness of the Cheyenne sandstone in this section is 
40 feet above which are 123 feet of Kiowa shales the top of which is 
not shown. This indicates a thickness of over 163 feet for tie
