rate per 1,000 per annum — Census 1891—was 13.28;
Population estimated—was 12 42. The corrected Death rate
(i.e., taking away the 11 Deaths occuring in Orsett Union

per Inhabited
House.
2.6 acres to 1 person. In no part is there any great
overcrowding of houses. I do not know the number of
inhabited houses in the district, but estimate the number of
inhabitants per house at between 5 and 6.
Chief Geoligical
Features
The Geological formation underlying the district is
chalk, which crops out at Grays and Stifford. Thanet sands
occur on the uplands of Aveley, Grays, Little Thurrock,
Chadwell-St.-Mary, and West Tilbury. Woolwich beds at
parts of Orsett, South Horndon-on-the-Hill (Pump Street),
and North Stanford-le-Hope. London Clay crops out at
Bulphan and the adjoining parts of Orsett, Horndon-on-theHill
and Laindon Hills, Corringham and Fobbing. Patches
of Bagshot beds occur at Laindon Hills (the top) and Dry
Street, Fobbing. Brick Earth and Gravel at various places.
Alluvial deposit on the whole South border of District and
greater part of the Eastern boundary, and at Orsett and
Bulphan Fens.

are Marsh lands, varying in width from a few yards (at
Purfleet) to miles on the South-East and East. At the
