From this determination of Omaha, it seems that 31.9 feet must be 

 axlded to ail the elevations of the U. P. E. E. to give the true height 

 above the sea ; but the range among the results is so large that the 

 leveling across Iowa must be very poor as compared with that of the 

 lines east of the Mississippi Eiver. 



Omaha cannot be considered as well determined as Kansas City ; but 

 this mean of five level-lines is much more probable than the old deter- 

 mination, which rested on barometric observations.
