MISCELLANEOUS NOTES AND OBSERVATIONS. 
117 
The bottom of the boring is 510 feet below Ordnance datum. The 
well and boring are 56 yards from the old well and boring made in 
1873, and the two wells are connected by a tunnel at a level 
of 147 feet above Ordnance datum, so that the water from the new 
boring passes to the old well, where it is pumped out. The yield 
from the new boring is about 600,000 gallons a day. The work, 
which took three months to complete, was carried out by Messrs. 
Hill and Lester, of Great George Street, under the superinten¬ 
dence of Mr. John E. La Trobe Bateman, C.E.— William. Verini,

Section at the St. Albans New Water Works.-— The boring operations 
which have been going on recently at the bottom of Holywell Hill 
have resulted in a continuous supply of excellent water at a depth 
of 150 feet, at a temperature of 50° Eah., the quantity obtained 
being 16,000 gallons per hour. The boring is lined down for the 
first 50 feet with screwed round wrought-iron tubing. The strata 
passed through were as follows:— 
Surface mould 
Gravel, sand, etc. 
Chalk flints 
Bed gravel and sand 
Chalk and flints ... 
Hard flint

The pumping work is being carried out by Messrs. G. Waller 
and Co., of the Phoenix Engineering Works, Southwark, for the 
local Water Company, of which Mr. A. E. Phillips is engineer.—

Section at the Sewage Farm, Watford Fields. —A chimney-shaft 
has lately been built at the engine-works, and as a somewhat deep 
excavation had to be made so as to get a solid foundation, I thought 
a notice of the section would be of interest. I may remark that 
the situation is so low, being below the level of the Eiver Colne, 
and the soil so porous, that great difficulty was found in keeping 
out the water—at least 100,000 gallons being pumped per hour. 
It was noticed that water rose in the sumpt hole higher than the 
water in the adjoining ditch, only 10 feet from it. The section 
was as follows:—Broken ground, 3 feet; clay and soil, 18 inches; 
peat bog, 4 feet 6 inches,; then flints and gravel. Some bones, 
probably of the red deer, and some stags’ horns, were found in the 
peat bog. I think there can be no doubt that this was the bed of 
a lake. The gravel is water-worn, but higher up it is angular. A 
few drifted fossils are found in it.—A. T. Brett , M.D ., Watford.
