Councillor Kuddenklau inquired by whose authority the Government was asked to validate the objections made by the Council to the assessment roll. It had never beea before;

ft". . == "the Council, and it seemed to him that a gi-eat deal of busineaa was being done outside the Council which ought not to be. The Chairman said that he knew nothing of the matter ; in fact he waß surprised when he read in the papers what had been done. Perhaps the Town Clerk could give some information on the matter. The Town Cleric : I received instructions from his Worship the Mayor to telegraph to Wellington. Councillor Jan>Aßon : I thmk the matter rests' with the M-Avr. sChe matter the\Kjjppped. "PINi-NCE. The Town Clerk reported as follows : — Seceipts for tlio week ending Api-il 13 — £226 10s ; for the week endina: April 20, £91 12s ; total £318 11s Id.

The tender of Mr G-eorgo Ebort for sweeping the side eli-vnnels, cleansing culverts, &c, for twelve months, for £750, was accepted. , TltE BUILDING- BY-LAW. Tttr Fail' attended the Council on behalf of Messrs Taylor and "Eowloy, and asked permission to continue the erection of a building of wood and ivon which, in ignorance- of tho byrlaw, had been begun in High street, near tfce Borough hotel. He might state that Messrs Wilson and. Sawtell had ei-ecfced a similar 'building two years ago. "On the motion of Councillor ]6riggs, •seconded by Councillor Toomer, it was resolved, that Mi- Farr's request be refused, •and that the provisions of the by-law be •enforced. , The City Surveyor was instructed to include in his fortnightly report all- applications to ■pnt up new buildings within tho city. The City Surveyor said that Mr Anderson, of tho Canterbury Foundry, wished to jnit up temporary offices in Cashel street until he ©ould build new ones in Liohfield street. The Surveyor was instructed to see that the provisions of the Act were enforced. " '■'■' ' HOUB OF MEETING-.

To h'.s Worship tic Mayor and ths memberj of the -r- City Council. • <}ontltiin3n,— ln Mr Cl^rTi's rsporh on the pl*ns fm: the -water sv.pyly of Chvisfclmrch, he states mat they have fail'jil to comply witht- c conditii>n» oPthe competition as regards onai-tity and pres--Bure..

Mr Clark say 3:-" Tho heighb of the column of ■water which will furnish HI.-; cubic feet per minute, an*l a jet 100 ft high, hi*jh, is 149 ft, or 40n. otpressurc is requiced to overcome the friction of th&w^turin p;iS3i;ii; tho water through the amall nozzles p? the Fi:--i I l*-it-;ado. ! The w must be taken iit a height in tie river as nt A in the diagxain, .iWliifjli 'nhaii be suflicien--. to force the water tl^ro'irh o. jjipe oi sufficient Size to furnish 1U.4 «übic i'eet per mjuut-' at'the top of the coluuin BC, 140 ft lii^'i ht Ca' Jipdral-sq.vin.re; jm 1 in ca'culntiujj the sizo of tho pips, the inclination taken into caJcnJ.i-.au must be the lino AO und not AO, as sp^ne-ii'3 *o have beou done in every caso. •■* 12-incH pipe, as proposed in several of the Bciienisa, would discharge somewhat more than the 1114 'c;i\iic feet per minute at B if it there had an Open cud and no pressure was required. By my celciilition the'neurcst point on tho river where the reqnisit » o'ovation cuu be obtained is II miles from CkxißtcUiu-cU ; thg olovatiou is there 195 ft, and the inel'.r-;- .loji oi.rain-3 i iliei-e issaiiiciei't-b'i collect the ■water fr.nu the riv.->r and discharge it through a pipe loiii in diameter at the elevation of 140fr,. Aecordiu^ to this calculatiDn, there « uot on* 1 of the echemi-awhich will .comply with this condition aat-og. .-diiHty andpresaiirs from the Waimakariri ■eia source of supply." Ifqw Mt Clark, ic-m tho ahoye st-itenient, would 32)&ke''it cpiicnr, that the competitors havn heen misr t%kep. in their calculations.; ab regards my own calculi'-io:. I have, I liiaintiiu, iiiade n » such mistake, I>".t I itn.-it admit that either Mr Clark or myself hvr,\ mado a -mistake as to tho reading of tk^ conditions attached to the water supply eoinpptuaon by the City Council. Aud I. \muk.-it .is l^r' Clark who Ms misread these conditions, for this reason: At the comm<>nc^ineht of hi-< report he quotes verbatim the conditions of the City (Council, ua advertised, regarding the supply aud pressnro, l»ut a little lower down he condenses •them -as follows :—" Briefly stated, these are - that •one inillLu gallons per day, suitable for domestic >pprposcs nhall be supplied' at a pressure capable of -giving v. jet of 100 feet high, in the centre o£ tlie •city," There can he no misapprehension as to Mr Clark's meaning, but his version of the conditions is, I wish t& point out, a different one to that issued by the Council. As the Council puts tlie conditions I cannot rend them to mean that it the whol^ of the ■«ater were drawn off as fast as it entered the pipes it'eliould be capable of throwing water 100 feet high, but that under pressure it shouid ho capable of •throwir.£ 11 jet the requirpd height. So you will see that Mr Clark has altered the "wor-i syr of the conditions, which enahles him to Bay .that we are deficient both in quantity and •pressuto. Ah a competitor, Tdo not think it would be good' taste in me to oiticise any of the competing sohenies, but with Mr Clark I feel no such restraint, aad ths mor-' so because his schp.me seems to directly Compete with mine, so far as nuturul filtration, supply aud force are concer.. cd. "When speaking of any scheme he Bays, "In one *?oheme an ingenious proposal is mad*- to obtain the water from cylinders BOnk ob an island in the river bed." Mr Clark then proceeds to sty that the filtration is limited to the eectioual area of the cylinders, which is an expensive arrangement as a great miiuber of cyliuders would bo required. Now, before I decided on having nine (9) cylinders as proposed, I ft.-?certainoii from actunl esperj snentthe rate at which water would rise through an -artesian wi-11. 1J inch t ore, tapped six feet helow the greatest height at which it would How. I found the discharge to be between ten aud eleven gallons per minute, that is to sny 70 pipes, 1J inch bore, would supply something more than the million 1 gallons required. But the .-.ectionil area of one 33 Inch cylinder would be equal t.> tho united sectional areas of 578 artesian 1^ inch -pipou, and if the water entere'l tho larger cylinders in theWaimakiriri at tie same rate as it enters the ordinary artesian pipes. <mo cylinder would bo far more thau BnJfieioiif; to deliver the required quantity. But it is quite certain that the r*ue o' ingress per square inch ofsecfcibn'al aiea would be much less in the. larger cylinder than in th-3 smaller inpe. There ia, so fur as I know, no rulu by which the differe/ce could he calctiifited. T^e'iovo that the inimbcr of cylinders (0) I have named i 3 co..B : .derahl.y more than need bo used. This question mi^ht, however, ho easily solve! if ifc should ho thought worth while to f-->lvo it, by sinlting one of thorn to the dsnth I have mentioned, und as I have already" propos'.?*t, and a-? Mr Clark also' propose?, with iv-j.i'-et to tLe trench to Tihich reference will \>B mad.o hereafter, pumping it rut and so ascertain the ralo nt wliioh the wa'or conies into it. MrClark olj°orves " at various ppviods of time the WuiSnatyrJ! i river has ocoupiod tliiTerent positions over thp eniii- plain and ho 3 brought ilov/n the jjebbles mid si-id with which its present bed i-* strewn, aud which extend over theplain tiudcrthe surface mould. The Htre:*.Ti ' art vepreeonted by tvhati* visible, is but ft small -jt.ii-n oi' th<> entire iiu^ntity, a larga portion passing ilirou^'h the shiagh? and sand, not only in the 1>B(T o:' tlie river, hut morfi or less in the plain through v/hiuh it flows. If a trench be cut in the plain of sufficient depth be'ow the surface of the stream, and poxalkl to its course tie water

will collect therein, and be naturally filtered ; and if the trench so dvg 1 be contiuued with the fall of , the plain, 20 to 28 feet per mile, a stream of na ur- , ally iiltered water will be obtained, which '• can be carried by a 15in. pipo to Christchurcli, and be delivered with the required pressure if it commences eleven miles from the city. I am unable to say what would bo ' the length of such a trench to collect lll"4 cubic ■! f««t per minute, but 1 have assumed that half a mile ! is amply sufficient, but if not it can be extended to any required length. An implement has lately been inven'jrd ■ Messi'3 Bruce and BatlioV . uxeaj to.: or — by which pebbles, gravel, sand, &c, can ' be readily an*l cheaply excavated under water; it" this be done to a depr.h of 3 or 4 i'eef. below tbe water level, and stoneware pipes with op an joint** be l»\id in the trench covered wibh lino shingle, t.bo encr.ince of f-atid -will bt> prevented, a'*d th.j water colli?c.etl will -be. free from all vegetable and susi podded impurities. ■ " The excavation of such a trench, 12 to 15 feet deep, with- the requ site land, I estimate v/iil cost ; about £.3.30 ii, or much less tban the filter of ordinary construction f.ir on» million gallons per day, witu spare area; while tho necessity lor any d.ims or reservoirs, or iutei't'erouce with tho 'river, will bo avoida'l." . ■ .Now it will be se^n from the above quotation, thai Mr Llirk has gone about one mile higher up the river than I have to gaiu a greater pressure, iiiud has adopted a citoti-water trench outside the rivor bank to collect ;.is supply of water, in preference to using cylinders as adopted in my scheme. Mr Clark proposes to take his .supi-1? of wator from a point on the bank of th* Wuhnak-iriii eleven nukstVo-.n Uhristehurch, and ::t a height of 1 OS lees above hk-3*t water, marlr, or ISJ feot> iibjve the centre ol tbe City. His i 3 quite eonvet as to the river being 19u feot abov-) Jiigii water mark eleven mil us from Christoliurch, and also us to that spot, being 1-.-2 t'eet above the oi-ntiv of t o City. Ho i« also riaht when he says. '• ii the troiich so du^'ba contiu'iod with, tlio fall oi thi pl;t;no, 2.0 to 2$ i'eet pur luilo, a stream o£ iiatnrally liltorail water will be obitninacl." He is right ss ong ;is his trench runs parallel with the jiver, but not i; the trench were cntufc /ight angles with the rive.-, i ti-'m't thmk tb. it Mr Clark wo.ild a; tempt: ;o construct bis works with In ;;. quarter of a raila from the rivor ; if so ho must allow for the water lulling :i3 it runs- or filier.-s through tho sliingle at right, angles from tho river to the tr nch. Itwi.l bo seen by my quotation that IVlr Clark c:'.usid rs that his tr,:uch will req'ui;o 3 1 >ba dug ab:mt 15 feet ueyp, and so farlbjlieveheisrigrit, buc •he oniita t> di-duc this 15 t'eeo from lSi leet that he reqaii-os for pr-.-ssurci. Hut this I consider is only an oversight, and I. will uot dwell upon it, an is* doss not :iUer the jiducipls of his ucheme. He "\fill only .have to go a little higher up the stivainto get the require I height. But thc-ro is another dldiculty tLai Mr Clark has overlooked, probably from tho absence oi: local linowled^o", and that is, when the whole of ;ho river runs under tbe n'-rfch bank, as I ha.'.*e known it do sevoral times iv winter within thi last t!5 yem-c', particularly at th.v times when a aroat portion of the river run dowu what is known as the north branch of the Waiuiakariri. . . Mv Clark's- citoh-ivater trench would then bn at leas:, one aud a half jnilea froia the stream, and buforj the water coxtli lilter thronyrh. t-lic jrrarel that •'italics at light angler, from tho .strcnui, it woul>i.be ut the least £0 feac below t.ho bottom of the tronc i. Iveuturo to suagest that it* Mr Clare had been award of the diilienlty now referred to « irh resp ct to the trench, he would not 'have vecommeuded it.i.v praleronce to my proposal, on the score ot cheapness. , I have infc'.'ntioiially avoided proposing to construct any w .rks near the bank of the river, ihe safety oi winch wouid bo dependent uijon. tho. uLabi;iti - ol the bank. Sly Ins; objoctiou to Mr Cla- k's scheme is its filtration. • He depends for his supply of -srater upon tho surface water ot' the river, at least upon the np;>er str.'itnai not exceeding threw or four feet in daiicb. '('but, in tisne of fr^sues, comes down loadod wi-h mud, aii'i 1 greatly question if it would be thorouyhly iiltered. 1 aido very much question if fuie sand would not find its iv.i.y into ihe earthenware i>!»d3 that ho'pro-poo-s i >luy lojigitudiually :n tho crea-h. If s~j it wenll bo >.oeessary to have:L Sf-coud trench to use while the other is being cleaned. iliiefly btaterl tbe dillereute batweon Mr Clark's scheme iii;d mine is — First -Mr Clurk reads the .c- ; >ndi'ions to maan that a large suj>ply of watar is reqairad with a greater pressure, so he gives a u 5-ii. eh maiu where I projiote a 12-incii o c, and to fjit;ii :i greater j)Assure tlim I have giv^n he, koub hbxh r up the riVor. .s Suu.'nd— Mr Clark get.s hi.-; Rupply Irom a trench cut outside the'rivor, that cauo-ly »!r i.v/.itti supply from the aiirfao^* -river water, while 1 propo'o to draw mine f rom a curivnt rtiuiiiug 25ft below the, sur ace oi ! the river.
