the direction of Omahu, the depth of the wells diminishes with 

 great regularity. Thus, at Meeanee the wells are 160 ft. deep. 

 at Roseneath (midway between Meeanee and Taradale) they are 

 100 ft., whilst they vary from 60 ft. to 90 ft. at the latter place. 

 At the site of the old Farndon Hotel the artesian well is 135 ft. 

 in depth, at West Clive water is reached at 130 ft., at East Clive 

 90 ft., and at the Grange and in the vicinity of the Big Bush 

 at depths varying from 60 ft. to 85 ft. The variation in depth 

 at the places named corresponds to what might have been ex- 

 pected from the troughing of the beds in the directions indicated 

 already. 



It will be noticed that the increase in the depth of the first 

 water-bearing bed from Pakipaki to the sea corresponds in a 

 striking manner to the. slope of the plain between Roy's Hill 

 and Te Awapuni. as also to the increase in the depth of the sea 

 along the area of depression. But we are led to assume that the 

 same saturated bed supplies the whole of the wells of the first 

 series by reason of the fact that they all have the same height 

 of flow above sea-level, if allowance is made for friction in the 

 different wells, as they deepen between Pakipaki and the sea. 



Perhaps the best illustration of troughing and of the same 

 source of supply is to be found in Napier itself. It is not necessary 

 to refer in any detail to the number of wells within the Borough 

 of Napier, but so long ago as 1888 several 6 in. wells were put 

 down in Monroe Street. At the first well in the street towards 

 Clive Square, and 24 chains from the hills, a 6 in. well was put 

 down, and water was struck at 156 ft. A second well was put 

 down 14 chains further along the street in a south-east direction, 

 and water was struck at 196 ft. The value of these wells from 

 a scientific standpoint was enhanced by the fact that three 

 years earlier a well had been put down at the junction of Has- 

 tings and Munroe Streets, which is just 19 chains further to the 

 south-east, so that three wells in the same straight line gave 

 the following depths : First well, 156 ft. ; second well, 196 ft ; 

 third well, 240 ft. ; whilst 33 chains separated the first and 

 third wells. The same water-bearing beds clearly supplied the 

 three wells, as the height of flow was similar, and the striking of 

 water in the second well perceptibly influenced the flow in the 

 first well, as it did also the flow of other wells in the immediate 

 vicinity. It seems to me that the upper water-bearing area 

 over the district is connected, but it is certain that there are 

 also areas where water is available which appear to be isolated 

 and very limited in extent. Thus, in the case of Havelock, the 

 wells between Hastings and the bridge that crosses the old bed 

 of the Ngaruroro in the direction of Havelock are clearly con- 

 nected, but the wells that have been sunk in Havelock itself are 

 of varying depths, and must either belong to a second water-
