This water is one of the purest commonly found, and with care to avoid surface contamination would be most suitable for domestic and for table For brewing purposes, however, and especially for ale-brewing, it is FIG. 2.-Section of Llanrhaiadr (Pentre Meadows) Bore-hole. June 14, 1875.

too soft, and therefore cannot be recommended, though for stout-brewing it would offer some advantages, and should a suitable supply not be obtainable additional hardness might be added to the water artificially.

There is some slight evidence of organised impurity, indicating admixture, to a small extent, with surface water, which would need to be guarded against if the supply were adopted.

Prestatyn Wells. Analysed by Dr. LLOYD ROBERTS, August 10, 1888.

Rectory Well (Pump), Prestatyn.

Chlorine: 64 parts per 100,000 = 4.48 grains per gallon.

Bronwylfa Garden, St. Asaph.

Surface well, in red sand.

Deep Well at Hafod-y-Green, Trefnant.

About 90 feet deep.

Analysis made by Dr. CAMPBELL BROWNE, December 15, 1877.

This water contains a little organic matter and the remains of oxidised animal matter of some kind; but the quantity is not large, and probably the water might be easily kept sufficiently pure so far as these constituents are concerned. It contains a very excessive proportion of common salt, and a considerable proportion of chloride of calcium and sulphate of calcium and other phosphates. If this can be accounted for by the infiltration of sea water through the sand, or by the occurrence of salt deposit in the rock, the saltness may be considered not to affect the wholesomeness of the water; if the saltness cannot be accounted for in this way the water must be considered a suspicious one.

1. At the Shropshire and Montgomery Counties Lunatic Asylum, Bicton, near Shrewsbury. 1a. In 1891 and 1892. 2.267 feet above Ordnance Datum. 3. Depth of well 117 feet, diameter 6 feet. Depth of bore-hole 190 feet, diameter 8 inches. 3a. 107 feet to the top of Storage Heading; length, 31 feet; contents, 11,400 gallons. 4. Water stands about 105 feet below the surface before pumping, and is lowered about 2 feet when the usual day's supply is pumped. The ordinary water level is restored in about three hours. a. 106 feet was the point of water level in the well; but when the bore-hole was put down the level was raised nearly 1 foot in the well, to which point it barely rises now. 5. In May 1893 the duplicate engines and pumps were worked together, pumping off 7,200 gallons per hour, at the rate of 172,800 gallons in the twenty-four hours, with the following results, the valve controlling the supply from bore-hole being fully open, viz.— Ft. in.

No further reduction in the water level was made. The average quantity pumped is about 45,000 gallons daily. 6. Only as before referred to Query 4a. 7. Not affected by rainfall. The water stands about 5 feet above the summer flow of the River Severn. 8. Analysis by Mr. Blunt, Public Analyst for Shropshire :

An approximate analysis of solids gives the following results :

This is an excellent drinking water, free from all trace of animal contamination; it is, perhaps, a little hard for general purposes, as is the case with all the water of the district. Water used for laundry purposes is softened.

9a. A steadily increasing yield of water was met with from 106 feet. The greatest increase was from the bore-hole below 150 feet, which caused the water level to rise in the well. 10. Yes. 11. Yes, the well is lined with iron cylinders to the depth of 85 feet. 12. The Permian measures outcrop about 700 yards south of the site. 13. No. 14. No. 15. An old well under the asylum buildings has been abandoned and filled in on account of the surface water finding its way into it.

1. Hinnington, on the Hatton Estate, about 2 miles south of Shifnal, Salop. 1a. Tube wells driven in 1889. 2. 172 feet O.D. approximately. 3. Three 2-inch tube wells are driven to the depth of about ten feet, and connected by a horizontal pipe under the ground surface. за. 4. Water stands about two feet under the surface of the ground outside the tube. a. Wells; it is lowered only ths of an inch while pumping. On ceasing to pump the ordinary water level is at once restored. 5. The yield of water flowing freely through the pipe connecting the tube wells together was found to be 64,800 gallons in the twenty-four hours. Pumping into a storage reservoir containing 30,000 gallons takes place twice during the week; the daily consumption is about 3,000 gallons. 6. Water level does not vary, (7) and is not affected by rainfall. 8. Analysis.

'A pure and excellent water both for drinking and general domestic use.'

The Permians outcrop about one mile on the west. 13. No. 14. No. 15. No. 16. Wells on the north-east of the estate, after being deepened on several occasions, have been abandoned on account of the steadily decreasing water levels in the Bunter beds, occasioned by the pumping operations at the Cosford well and bore-hole of the Wolverhampton Corporation Water Works.
