tertiary marl in places very wide apart; e. gr.,west of Garden City, on the Cimarron 

 river, in Meade county, in Comanche and Barber; and we are inclined to think an 

 isolated patch near Wellington, in Sumner county, also belongs to it. This being 

 so, the future maps must recognize the tertiary formations in the south as far east 

 as the sixth principal meridian. As we show elsewhere, this fact is of economic value 

 as bearing on the water supply of the west. In one place the tertiary grit yielded 

 abundance of a pretty fossil univalve. 



In the wild region stretching west from Medicine Lodge into Comanche county 

 another problem has to be worked out, viz., whether the red rock and the gypsum 

 belong to Cretaceous or older formations, Triassic or Permian. The beautifully 

 variegated sandstones referred to by Professor Cragin in a printed notice of a run 

 through Barber county I am inclined to consider as undoubtedly Dacotah, but in the 

 only place where I got at their base they seemed to rest on the eroded surface of the 

 Red Rock. On the other hand, in the west part of Sumner county we found a red 

 clay intercalated with the well-known Permian strata. This clay was so like the clay 

 of the Red Rock series that it seems to be a premonition of it. The line of contact 

 of the undoubted Permian and the Red Rock series runs through Harper and King- 

 man counties. That line calls for investigation. 



There are many matters of interest that will be dwelt upon by investigators of 

 the southwest: caves in the gypsum, the habits and habitats of animals, great fossil 

 remains; but one of the greatest wonders to be made known will be the story of 

 EROSION, which a geologist able to read his record will have to transcribe and illustrate 

 so that others may understand how hills and mountains are carved out of the dead 

 level of the prairies, and how the hardest rocks marked by the stylus of the ages are 

 read like rolls of ancient seers. 



ON THE OCCURRENCE OF BROMIDES AND IODIDES IN THE WATER 

 OF AN ARTESIAN WELL AT INDEPENDENCE, KAS. 



BY PROF. E. H. S. BAILEY, LAWRENCE, KAS. 



Some time since, in boring for coal, a well 1,091 feet in depth was sunk at Inde- 

 pendence, Kas. The well proved to be of value in furnishing a strong mineral 

 water. This brine has a specific gravity of 1.0.52, and issues at a temperature of 

 62° F. The well is piped for 400 feet, and the water is pumped from a depth of 

 about 300 feet. 



On analysis the water was shown to contain the following constituents, expressed 

 in grammes per liter:
