THE CAMBRIDGE WATER SUPPLY.

Mb. Gwynneth, G.E. has now finished the necessary calculations in reference to the four streams or sources of supply inspected by Messro. Houghton, Hewitt, and Kirkwood on Friday and Saturday last. The result of his observations which we append in a tabular form, includes estimate of the probable cost of bringing- the water from each source to the English Church Cambridge, the disr tance from town of each, their altitude above the site of the English Church,, pressure per square inch, and quantity which can be delivered per diem of ten hours with the estimated cost of each scheme. To the report which Mr. Gwynneth lias supplied to the committee he appends a commentary on the adaptability of each scheme their probable defects which urge against their being adopted, and other features which show strongly in their favour. He thinks there is not muoh difference in the quantity of water running in streams inspected witto the exception of the Karapiro which at the altitude of 190 feet he , says is a splendid stream, even at this present dry season. The water in each stream he says is of very good quality and he strongly recommends the adoption of the Karapero stream as the source of supply, if the money can bo obtained for it, as it will be a never-failing supply. As to the others, he says, " though probably sufficient for the next ten or twenty years, if the population trebles in that time, they may be found insufficient." As to which scheme shall be adopted, he leaves this entirely with the people who have to pay for it, to consider. If the comparatively enormous cost of the Karaporo scheme prevents the ratepayers from adopting it, lie recommends Hally's Creek R8 the next best, where there is a good site for a reservoir, two streams being adjacent to each other, and capable of being connected. The quantity of water he thinks is greater at Pukekura than at any of the other sources, but there is no means of supplementing it by caeting 1 another stream into it, being at m altitude of 200 feet, but at each of the other streams this can be done. At the end of his report he says: — "I have estimated each stream .separately, as accurately as pobsibie from the data at my disposal, but on au accurate survey being mado of whichever scheme you may decide upon, a moro reliable estimate can be made."
