been very heavy in crops and damage to soil. The loss of live 

 stock drowned would probably have been almost as heavy had 

 it occurred in daylight, owing to the very rapid rise of the 

 streams. The estimate of $100,000 total loss is not far from 

 correct. 



There are oaany other interesting features which should be 

 written up. The weather conditions can be obtained from the 

 weather bureau. The map for the date shows a low reaching 

 into Iowa, but would not warrant a forecast of general rain 

 The energy liberated by so heavy a fall of rain would form an 

 interesting study. I have collected some data concerning 

 similar storms in previous years. The heaviest fall that has 

 come to my notice was fifteen inches, at Wilmington, Del., on 

 the 29th of July, 18 i9. 



THE BURLINGTON ARTESIAN WELL. 



BY FRANCIS M. FULTZ. 



Work was commenced on the Burlington artesian well about 

 midsummer of 1896; but, owing to cessation of operations for 

 somewhat more than a year, it was not finished until midsum- 

 mer of 1898. The well is located in Crapo park, and the 

 expense of putting it down was borne out of the park funds. 



It was expected that a flow would be reached in the St. 

 Peter sandstone at a depth of about 900 feet. This belief w^as 

 based on the flow obtained at the Ft. Madison and Keokuk 

 wells, south of Burlington about twenty and forty miles 

 respectively. As will be seen from the subjoined section the 

 St. Peter was reached at a depth of 950 feet. No flow was 

 obtained, but the water rose to within thirty-eight feet of the 

 surface, and indicated a strong supply. There was no further 

 change of the head of more than a foot or tw^o, although the 

 drilling was carried down to 2,430 feet and passed through 

 at least two other water-bearing strata. 



The diameter of the well is six inches for 1,700 feet and five 

 inches for the balance. No casing is used excepting through 

 the loess and drift. At 1,700 feet a test was made of the 

 capacity. Over 100,000 gallons were pumped out daily for one
