well to be described, was begun under the direction of Mr. Mi:lne, 

 collector of the customs for the port. The spot fixed upon is 

 opposite to the termination of a street leading to the harbour, 

 and has about six feet of water, at high water, in ordinary 

 tides. 



After the workmen had boied through twenty-eight feet of 

 vcrv solid clay, and afterwards through fifteen feet of a creta- 

 ceous flinty gravel, of a very concrete texture, the auger was 

 perceived to strike against the solid rock ; but as they were not 

 able to make any impression upon it, the work was given up for 

 that tide, without any appearance of water from the first. In 

 an hour or two afterwards, the bore was found filled to the top 

 with fresh water, of the most limpid appearance: it soon flowed 

 over, and was even projected some inches above the summit of 

 the bore, in a stream equal to its calibre. When it was ascer- 

 tained that the water was of the purest quality and taste^" per- 

 fectly fit for washing, and every culinary purpose, the bore was 

 properly secured bv an elm stock, ten feet long, and perforated 

 with a three-inch auger, driven to its full length: a copper tube, 

 well tinned on both sides, of a circumference to admit its being 

 passed through the bore of elm stock, and thirty-two feet in 

 length, was then forced to the bottom of the bore, so as to rest 

 on the rock. The upper part being properly puddled round the 

 elm stock, and the well thus completed, the following singular 

 circumstances were observed, and have continued with great 

 uniformity ever since. 



As soon as the surface of the sea water in the harbour, during 

 the flowing tide, has arrived at a level of forty-nine or fifty inches 

 lower than the top of the bore, the water begins to flow from it 

 in a stream equal to its calibre, the impetus of which is increased 

 as the tide advances, and may be observed to be propelled with 

 much force after the bore is overflowed by the tide. The dis- 

 charge continues from four to five hours, L e. till the tide in re- 

 turning falls to the same level where it began to flow: at this 

 point, it ceases com})letely till the next flood shall have regained 

 the same level, when the same phsenomena recur, in the same 

 succession, and without any variation, but what arises from the 

 different degrees of elevation in the tides. The rule appears to 

 be, that the column of spring water in the bore is always sup- 

 ported at a height of forty-nine or fifty inches above the level of 

 tlie tide, at any given time. This at least was the result of 

 t very observation I made during several successive weeks, in the 

 months of July and August last ; and I am assured by Mr. Milne, 

 on whose ingenuity and habit of accurate observation I can place 

 i!ic firmest reliance, that his habitual experience, for three years
