 1. North-east portion of Leamington. 2. 20-5 ft. 3. 80 ft. deep, 8 ft. diameter ; 

 234 ft. deep, 18 in. diameter. 4. Normal level 20 ft. below surface. 5. 750,000 

 galls, per day. 6. Works not yet completed. 7. Top of water is 26 ft. above 

 river Learn. 8. Analysis attached; water remai'kably pure and sq/i;, whereas sur- 

 face-wells contain very hard water. 



Analysis of loater from the new bore-hole, by Dr. Horace Swete, taken from a 

 depth of 200 ft. from surface. Water very clear, almost as clear as distilled water 

 — the smallest point being easily read at a depth of 2 ft. Temperatm-e at well, 

 50° Fahrenheit \ requires no filtration.

This water is an extremely pure specimen, even for a deep well, and requires no 

 filtration. It contains less than one. tenth of the amount of organic matter than the 

 present town supply, and is not only a softer water for domestic purposes, but 

 the deposition of carbonates causing incrustation in boilers is considerably less in 

 quantity. .

9. Map of strata previously sent, consisting of sandstone of various thickness divided 

 by marls. 10. Yes. 11. Yes. 12. Not within a mile, where one is known south 

 of Borough, and another two miles k-est. 13. No. 14. Yes, in the valley half a 

 mile south. 15. Yes ; the first experimental boring was discontinued in consequence 

 of finding, under the saliferous marls, very salt water, one layer of this marl being 

 more than 100 ft. thick.
