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. Header, 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 our 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.1
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
gravel which extends from the site to Galleywood, and which for many years was
the source of the supply of water for these works.
" The yield of the spring from this gravel formation varies from 60,000 to
120,000 gallons per 24 hours, and is now supplemented by water obtained from
the bore-hole.
" The surface level is 97ft. O.D ; the boring is 311ft. deep and 10in, in
diameter. It is lined with steel tubes of 10in, 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.
" The strata passed through are as follows :—
