locality. Quite a number of wells have been put down to supply the 
heavy demands at the works and in the paddocks. The older wells, 
my informant stated, have altered considerably. They alter immediately 
after гаш. During last season some of the wells ceased to flow. 0 
shower of rain starts dry wells, and increases the flow of others. All 
wells are down from 90 ft. to 100 ft. Mr. J. C. Crawley, of Longlands, 
situated between Pakipaki and Havelock North, stated, “ The flow alters 
in dry weather and immediately after rain." Mr. Buick, of the same 
district, reported having two wells, and that, following rain, a change is 
noticeable in the flow in about two days. Mr. C. Livingstone, another 
settler in the same district, reported having three wells, and that as the 
rivers increase in volume the wells flow stronger, reaching maximum 
strength when the Te Aute Lake is at its highest. 
Thus all owners of wells in the Pakipaki and Longlands distriets 
report a diminished flow in summer and an increase of flow following 
rains. In some of the returns from owners of wells reference is made 
to the occasional deposit of sand, and in several instances to the appear- 
ance of small crustaceans in the water. In most of the older wells a 
diminution of flow is remarked. In the Meeanee district a well throws 
up sand at intervals, and a little sulphuretted hydrogen is given off from 
water of wells that have been turned off for any length of time. Following 
the flow of water in a new well in Munro Street, Napier, it was noticed 
that if a piece of sacking was placed on the top of the pipe and hit 
smartly with a mallet the water for a minute afterwards was of milky 
whiteness. 
In two cases reference was made to the effect of high and low tide on the 
flow, one well being near the Shore, the other at Havelock. The lack of 
regular observation and the general intensity of flow seaward may account 
for the absence of information in this direction. 
In the case of a diminution of flow following a period of dry weather and 
of a return to normal conditions following rain, more facts would be welcome, 
especially in the case of wells extending from Napier to Clive Grange and 
in the Greenmeadows and Taradale districts.

It is likely that each river flowing across the plain does a share in 
supplying water to the underlying beds, but not by surface soakage. Water 
falling ав Tain on a definite area does not remain on that area unless retained 
in à basin; and soakage into beds can ensue at the outcrop of beds only.
