ARTESIAN WELLS IN DORSET AND ELSEWHERE. 197 



Other Artesian Wells and Borings in Dorset. Owing to ics 

 proximity to Bovington I would briefly allude to the Spyway 

 Boring. This is situated on a low exposure of London Clay 

 in Moreton plantation close to a keeper's cottage, and only a 

 few feet above the level of the Frome valley. The following is 

 an account of the boring : * 



1. Sand and Clay (Tertiary) . . . . goft. 



2. Chalk .. .. .. iizft. 



Total boring . . . . zozft. 



The result is stated to have been unsatisfactory, so that at 

 this place ii2ft. of Chalk was penetrated without obtaining 

 water. It is presumed that the goft. of Tertiaries belonged 

 mainly to the Reading Beds. The distance from the Bovington 

 Borehole may be about 2 miles, N.W. 



Messrs. Eldridge Pope and Co.'s well at Dorchester, f The 

 operations were conducted in 1880-1. The mouth of the well 

 is on the north side of the London and South- Western Railway 

 Station, and probably about 25oft. above O.D. The total depth 

 bored in this case was 597ft., wholly in the Chalk. A well was 

 dug for 7oft. and the rest completed with 6-inch tubes. The 

 water-level at the time work was finished stood at 45ft. Sin. 

 below the surface hence this well is " sub-artesian " like the 

 one at Bovington. The yield obtained was 3,000 gallons per 

 hour. The first indications of having struck a supply of water 

 appear to have occurred after the boring rod had passed 

 467^. Hence in this case nearly 5ooft. of Chalk was pierced 



* Supplied by Mr. Kellaway, smith, of Bere Kegis, who executed the work 

 several years ago. 



f For the particulars subjoined I am indebted to Mr, Alfred Pope and to 

 Messrs. Le Grand and Sutcliff.
