Their supply of water will be best seen for purposes of comparison in tabular form, as follows: Railway wells on the high prairie (liurlington and Missouri Railroad). Akron, which is beyond the limits of the field of this investigation, being well upon the prairie west of the sources of the Eepublicau, has also a town well yielding 12,000 gallons a day. The railway well has a wind pump with a 20-foot wheel. The other stations in the table use steam pumps. That at Grant reduces the water to exhaustion, but it is restored again speedily. The well at Grant, and one at Venango, 190 feet deep with 40 feet of water, as compared with Imperial and with Lamar, whose town well is 90 feet deep with 30 feet of water, illustrate the greater depth near the northern edge of the plateau, and the depth at Holyoke illustrates the westerly increase. These facts are further illustrated in profiles (PI. XLII, figs. 5 and 0) taken from Mr. Follett's report' of 1891, which show by the statement of strata passed through that the grit formations come to the surface in all this region, which has been described here...
