The boring was commenced April 11, 1887, and lias a diameter of 12 

 inches. 



Information collected hy Mr. T. S. Stooke, G.U., Shrewshury, 



1. Sundorne estate, near Shrewsbury. Xa. In 1884. 2. 205 feet. 3. Well 

 was sunk 25 feet in depth and yielded a considerable quantity of water, which was 

 not found desirable for use ; consequently a borehole was put down cased with 5 inch 

 tubes to the depth of 88 feet. The borehole was continued to the depth of 76 feet, 

 8 inch diameter. 3«. No drift way. 4. Little or no variation. 4ff . The normal level 

 of water in the well is 4 feet, while that in the borehole is 11 feet. 5. About 

 45,000 gallons ; the quantity used daily is only that required for farm purposes. 

 8. Analysis by Mr. Blunt, M.A. :— There is a reddish turbidity, which quickly settles 

 and leaves the water clear and nearly colourless ; the sediment is sandy. No lead, 

 copper, or zinc is present in the water. The following analysis gives the results 

 obtained from the clear water after subsidence : — 



Grains per gallon 



Total solid contents 50 



Chlorine in chlorides 8'5 



Nitrogen in nitrates 0-0 



Oxygen absorbed 0-012 



These data indicate an entire absence of sewage or other organic matter, but the 

 large amount of solid contents and of chlorine is anomalous, and it was thought de- 

 sirable to determine the hardness : — 



Degrees 



Hardness by Clarke's scale, total -■ 35 



Permanent (after boiling for some time) ... 9^ 



Temporary by difference . 25^ 



It thus appears that more than 25 degrees of the hardness of the water is due to 

 earthy carbonates, and therefore can be removed by boiling or by a precipitating 

 process vTith lime ; moreover it is generally agreed that temporary hardness is of less 

 importance from a sanitary point of view than permanent. The remaining 9| degrees 

 of permanent hardness is due to magnesium, not to lime salts, principally to chloride 

 of magnesium, none in sewage. The chlorides present are all, or nearly all, in the form 

 of chloride of sodium ; it is clear, therefore, that here the chlorides are of mineral 

 origin. On the whole the water must be pronounced pure and wholesome, but some- 

 what hard for drinking, and excessively so for domestic use.
