a natural cavity containing' a strong natural spring. 4. On entering the cavity, the 

 water rose to the surface with great rapidity, and rose 39 feet 9 inches above. 

 5. The yield was 575,201 gallons ; it has been pumped. 6, 7. No. 8. By Professor

lO. The surface springs in the top gravel were cut oS by a cast-iron pipe driven 

 tightly into the hard shelly limestone. 



The water supplies Bourn and the town of Spalding, 10 miles distant.

The following analysis, by Dr. Campbell Brown, D.Sc, of the beds 

 passed through are of interest in their bearing on beds since discovered in 

 borings to the east : — 



Specimen A. — Hard sandstone composed of angular grains, taken from the pebble 

 beds at 700 feet. 



Specimen B. — Eed sandstone, rounded grain, taken from lower mottled at 1,180 

 feet. 



Specimen C. — Slightly marly sandstone, composed of granular or powdery particles, 

 taken at a dejith of 1,280 feet.

The hardness of the water at 600 feet was less than at the surface or at the 

 bottom. The proportion of common salt increased from 600 to 1,300 feet.
