MEETING IN THE DANBURY AND LITTLE BADDOW 

 DISTRICTS IN CONJUNCTION WITH THE GEOLOGISTS' 



ASSOCIATION. 



Saturday, July 7th, 1906. 

 Directors : A. E. Briscoe, B.Sc, Miller Christy, F.L.S., W. Cole, 

 F.L.S-, F.E.S., T. W. Reader, F.G.S., and A. E. Salter, D.Sc, F.G.S. 



This meeting was a whole-day one, planned for visiting the commons and 

 woods of this delightful part of ovr county, and, with the assistance of expert 

 members of the- Geologists' Association — particularly Dr. Salter — special 

 attention was paid to the geology of the district traversed.* 



The party assembled at Chelmsford Station soon after 10 a.m., and proceeded 

 in brakes to Great Baddow, where the waterworks belonging to the District 

 Council of Chelmsford were inspected under the direction of Mr. J. Dewhirst, 

 A.M.I. Mech.E. , who had placed out a sectional diagram of the bore-hole and 

 samples of the various strata passed through for the inspection of the members. 

 His remarks are embodied in the following account : 



" The position of this bore-hole is at the outcrop of the clay bed forming the 

 valley of the Chelmer, and is the site' also of a strong spring of water draining the 

 giavel which extends from the site to Galleywood, and which for many years was 

 the source of the supply of water for these works. 



*' The vield of the spring from this gravel formation varies from 60,000 to 

 1 20 coo gallons per 24 hours, and is now supplemented by water obtained from 

 the bore-hole. 



" The surtace level is 97ft. O.D ; the boring is 311ft. deep and loin, in 

 diameter. It is lined with steel tubes of ioin. internal diameter to a depth of 

 350ft., beyond which are 8|in. internal diameter perforated steel tubes. 



" The work of boring was commenced in February, 1891, and was completed 

 in October of the same year.
