 on some Artesian borings along the line of the Union Pacific Rail- , 

 road in Wyoming Territory, by F. V. Hayden. 



These Artesian borings, seven in number, are located between 

 Rawlins and Green River, and were made by the chief engineer of 

 the Pacific Railroad, Mr. T. E. Sickles. The surface varies in 

 height from 6,224 to 7,100 feet— the latter on the "Continental 

 divide." The beds passed through were Tertiary or Tertiary and 

 Crctacous, and lie in a basin," very nearly horizontal. No. 1 

 counting from the west, near Rock Springs, 1,145 feet deep, stopped 

 at the bottom of the Fox Hill group of the Cretaceous, Kfd 

 afforded a flow at the surface of 960 gallons per hour, or 26 feet 

 above it of 570 gallons per hour. No. -'. near Point of Rocks, 1,000 

 -topped at the top of the Fox Hill group, and afforded 

 nit supply of water at 1 7 feet from surface. No. 3, near 

 , Bitter i r ek, r,',n; feet deep, descended into the Laramie group, 

 the upper part of the Lignitic series, "and yields 2,160 gallons 

 per hour, while flowing 1,000 gallons per hour. The most west- 

 ern, ju>t east of Crestou, 1,105 feet deep, reached to the bottom 

 of the Cretaceous, and yields 2,000 gallons of water per hour; 

 water ten feet from the surface."
