ity for building purposes, being composed of thick alternating 

 layers of both fine and coarser sand. Some of this is hauled 

 for a distance of fifteen miles. 



The low hills along the east side of the creek show for miles 

 this same structure of sand and gravel, which is covered by 

 layers of ''hardpan" and surface soil of varying thicknesses, 

 from three to fifty feet. In these are found two strata of 

 CaCo. nodules, so common in this region. At the places I ex- 

 amined they were from eight to twelve inches apart, from one- 

 fourth to one and one-half inches in thickness, and from six 

 to twelve feet below the surface. Much of this material was 

 found in the sand and soil about the tusk. 



Last year, in another pit about forty rods north of the tusk, 

 were found most of the bones of a human skeleton, covered by 

 about eight feet of sand and loam. Some other bones were 

 also found, but these had been destroyed, so I have not seen 

 them. According to descriptions given they were bones from 

 the skeleton of an animal of considerable size. 



The tusk was found on the north end of the west quarter 

 of section 6, in Jackson township, seven miles west and nine 

 and one-half miles south of Lindsborg, and one and one-half 

 miles west and four and one-half miles north of Conway, 

 which is near the western limit of the McPherson Eqiius beds. 



We have now in our museum collection one very valuable 

 fossil from this immediate vicinity. It consists of the greater 

 part of the skull of a Megalonyx leideyi Lindh. It was dis- 

 covered a number of years ago by Prof. J. Udden and described 

 by Dr. J. Lindahl, now of Cincinnati, Ohio. The skull is con- 

 sidered to be of great value, since it is one of the few, and, 

 besides, the most complete of any, ever found. 



The tusk has as yet not been reconstructed, but as we have 

 all the pieces it is hoped that we will soon have them replaced 

 and the entire fossil added to the museum collection as a val- 

 uable find from the Equus beds.
