The saline spring flows into a well, nepr a ridge of high The spring. 

 land, on the sides of which, at some short distance, coals 

 and iron stone are seen cropping- out. The well is about 36 

 feet in depth, and 7.J ^ eet hi diameter, The sides have 

 lately been fenced, to keep out foreign water, which was 

 supposed to run into it, witji a dam of bricks set in clay, 

 and lined with elm boards. 



The bottom is a ferruginous argillaceous sandstone, 

 through which is perforated a hole, whence the water issues, 

 and rises to within about four feet from the surface. 



The sides of the well near the top are covered vyith a yel- The water, 

 lowish ochrey substance. When the water is fresh taken 

 up, it is perfectly transparent and colourless. It is little 

 refractive of light, nor can it be said to sparkle ; but after 

 standing for a short time, numerous small bubbles of air 

 are seen adhering to the bottom and sides of the glass it is 

 taken into. After a time the water becomes rather turbid, 

 and at length a pale ochreous precipitate falls down, leaving 

 the supernatant water transparent. 



In large quantity the water smells of sulphuretted hidro- Its smell. •

When the temperature of the atmosphere indicated 40° of Temperature, 

 Fahrenheit, some water just taken from the well raised the 

 thermometer to 47-|°. At another time, when the tempera- 

 ture of the surrounding air was 75°, water taken from near 

 the surface of the well lowered the thermometer to 50°, and 

 a portion taken from the bottom to 52°.
