Ov the northern bank of the Saline river in the northern part of 
Saline county the Dakota (including the Mentor beds) forms the 
upper part of the river bluffs. Five miles north of the city of Sa- 
lina, in the western part of Cambria township, the base of the Da- 
kota is between 90 and 100 feet above the level of the Saline river, 
Or approximately 1300 feet above sea level. On the Salina sheet of 
the U.S. topographic map the 1306 foot line has been taken as the 
approximate line of division between the Permian and Cretaceous 
systems for that part of the sheet north of the Saline river. From 
the south side of the Saline river to the ridge southeast of Brook- 
ville the line on the map is only an approximation; but from that 
point along the ridge south of Bavaria, east of Soldier Cap mound, 
near Falun and around the northern, eastern, and southern flanks 
of the Smoky Hill buttes the line was traced with some care. To 
the south and east of Smoky Hill river in the northern part of 
McPherson county, on the western side of the divide between the 
Smoky Hill river and Gypsum creek, the line was traced by Mr. 
Beede. In Saline county the writer traced the line down the western 
and up the eastern sides of the divide between the Smoky Hill river 
and Gypsum creek into the northeastern part of McPherson county, 
in Delmore and Battle Hill townships. The line around the divide 
between the Smoky Hill, Cottonwood and Arkansas rivers in the 
northeastern part of McPherson and northwestern corner of Marion 
county was mostly traced by Mr. Beede, as well as the line in the 
western part of Marion county and the northern part of Harvey 
between the Permian and Tertiary or Quarternary sand. Mr. Beede 
also traced the greater part of the boundary of the deposit of sand 
in Marion, Harvey, Reno, and McPherson counties. 
THE UPPER PERMIAN FORMATIONS. 
MARION. 
The upper fossiliferous strata of the Permian consist of thin 
buff Jimestones, shales and marls, containing in places beds of 
eypsum and salt. These strata have been described by the writer 
under the name Marion formation! for which Professor Cragin,
