ON THE CIRCULAIION OF UNDERGRODND WATERS. 305 



Particulars of well-boring, given hy Mr. Henry Mellish, of HodsocJc Priori/, 

 WorJcsop, carried out at the same. [For questions see Appendix.^ 



1. Situated at Hodsock Priory, Work- 

 sop (Notts), on the formation marked f 1 

 on the map of the Geological Survey. 



Xa. Bored March, 1891. 



2. .5.5 feet. 



3. Sis in. borehole ; depth, 94 feet ; 

 no well. 



4. Water stands about 3 feet from 

 surface ; permanent pump not yet fixed, 

 but on completion of bore we tried it 

 with a centrifugal pump, which we 

 worked for the best part of a day and a 

 half. It raised the water at a rate 

 estimated at from 110,000 to nearly 

 1.50,000 gallons per 24 hours; when 

 running at the higher rate it lowered the 

 ilevel in the bore from 3 feet to 18 feet 

 (below the surface ; the level recovered in 

 B, few minutes on stopping the punnp. 



5. See 4. 



6. No data. 



7. Water in the bore stands about 

 1 foot higher than the water-level in the 

 surrounding soil. A mill-dam a few 

 yards away has its level some 6 feet 

 above water in the bore. 



8. Copy of analysis enclosed. 



9. About 6 feet of soil above the 

 rock, the rest all in red sandstone, with 

 a little marl in places, apparently in beds 

 a few inclies thick. 



9(1 and lO. Water throughout ; stands 

 abo It 4 feet from surface. 



11. Surface water kept out by iron 

 tubing to a depth of 55 feet. 



12. Not to m)'' knowledge. 



13. 14, and 15. No. 



Copy of Analysis. 



Grains per gallon. 

 Total solid residue 18-48 



Cuntaining — 



Oxidisable organic matter ....... -02 



Chlorine (equal to chloride of sodium, 1-48) . . . -90 

 Nitric acid as nitrates ....... 3'85 



The water also contained — 



Free ammonia -000.5 



Albuminoid ammonia ....... -001 



Hardness according to Clark's scale 13 



The water was bright and clear, and quite free from colour and 

 deposit ; it left on evaporation a residue which was white, and did not 

 blacken at all on heating strongly. 



The water has a mere trace of organic matter in solution, and hardly 

 any ammonia, and it is a beautifully pure supply for drinking purposes. 

 It not being excessively hard makes it also serviceable for general 

 domestic purposes. (^Signed) J. Augustus Voelcker.
