well at this locality, having a depth of 529 feet, cased 260 feet, 
owned by Mr. Tallant, was found, on the same date, to have a 
pressure of seven and one-half pounds, or a head above the

tion of these two wells was not determined, but the surface eleva¬ 
tion at the Tallant well is estimated at about six feet above sea.
