MEMORANDUM ON THE METROPOLIS SEWAGE AND ESSEX This scheme has for so long been a subject of public interest, now to add more in justification of the prospectus than give a very brief summary of the Parliamentary proceedings in relation to it, and an estimate of the profit likely to accrue to the Shareholders. It was for the necessary powers to construct the works named in the concession that application was made to Parliament: powers also being obtained for the reclamation of the Dengie Flats, and for the construction of the culvert shown by the blue line on the map. should it hereafter be deemed expedient further to develop After the second reading of the bill in the House of Commons, which was supported by the Right Hon. Wm. Cowper, her Majesty's First Commissioner of Works, it was, on the petition of the Corporation f the City of London, first sent before the referees, that the engineering features of the scheme might be thoroughly sifted. They reported as follows: Professor J. T. Way, Member of the Royal Commission on Rivers, the operations of the Company. and of the late Royal Commission on Sewage. BANKERS. Messrs. Glyn, Mills, Currie, and Co. Messrs Sparrow, Tufnell, and Co., Essex. The Bank of Liverpool. The Birmingham Banking Company. Messrs. Baxter, Rose, Norton, and Co. BROKERS. Messrs. P. Cazenove and Co. SECRETARY (pro tem)-Walter A. Michael, Esq. Offices-60, Threadneedle-street. The International Financial Society are authorised to receive subscriptions for the share capital of this Company, which has been incorporated by special Act of Parliament for the purpose of utilisin the sewage of the northern area of the metropolis, the concesion of which has been granted to Messrs. Napier and Hope. The con ession from the Metropoli an Board of Works to Messrs. Napier and Hope, as new confirmed by Act of Parliament is scheduled to the Act, and both may be spected at the Offices of the Company. The concession has been vested in the Company on condition of the payment to Messrs. Napier and Hope, under the provisions of the Act, of £50.000 in fully paid-up shares of the Company, and a amall contingent percentage of the net profits The concession recites that, in the opinion of the Board, the works proposed by Messrs. Napier and Hope are calculated to effect the three fo lowing objects, namely: 1. To divert the sewage from the Thames. 2. To render it innocuous, by its application to growing crops. 3 To realise the greatest money value of the manure contained In it. The first article confers upon Messra. Napler and Hope "the absolute and exclusive right to, and property in, the sewage," for a period of fifty-four years from the passing of the Act, but makes the following provision in reference to the application of the net profits resulting from the sch me after the expiration of four years from the passing of the Act Previous to the expiration of that period ail the profit results to the Company. After deduction of the annual charge for " money borrowed," and of the "working and establishment expenses," the net profit shall be applied 1st. In payment of interest at 5 per cent. per annum on the share capital. 2d. In payment in equal moieties to the Shareholders and the Metropolitan Board of the further profits up to 15 per cent.! 3rd. In division of profits exceeding 15 per cent. and up to 25 per cent. between the Shareholders and the Metropolitan Board in the proportion of one-fourth to the former and three-fourths to the latter. 4th. After 25 per cent. the division again to become equal. The object of these stipulations is, that while the Metropolitan Board are virtually to receive half the profits, yet that, in order to give a greater security, and therefore greater value to the shares, the Shareholders are to have a preference to the extent of 5 per cent., which is made good to the Metropolitan Board between the points of 15 and 25 per cent. at which latter point each party receives 12 per cent., and the division is then continued equally. Thus, the share capital of the Company derives the advantage of the entire capital, approaching three millions sterling, expended by the Board on the north side of the Thames, for the collection of the sewage at the point of its delivery to the Company. At the expiration of 34 years the Board have the right, on giving two years' notice, to require a revision by arbitration of the above apportionment of profits. The concers.on stipulates for the construction of a circuler brick culvert, 9 f. 6 in. in diameter, shown by the red line on the map accompanying the prospectus. and running from the Northern Outfall Sewer to the Eas Coast of Essex, and further, for the reclamation of the tract of foreshore and sand coloured pink on the map (about 7,00 acres): the intention being to irrigate the lands in the district through which the culvert passes, and to utilise the surplus upon the reclaimed land. A contract has been entered into with Mr. William Webster (who has constructed more than one-third of the Main Drainage Works of the Metropolis, including the Crossuess Ontfa 1) for the construction of the works mentioned above, together with the necessary pumping stations, for the sum of 1,853,44el. To this must be added the amount to be paid to Messrs. Napier and Hope in shares, as before mentioned; the cost of land, engineering, Parliamentary and legal expenses, superintendence, and management, together with interest at 5 per cent. per annum on the capital during the construction of the culvert, estimated at a total of 546,5521.; in all, 2,400.000l. The act authorises the Directors to raise the amount of 700 060. in debentures, but of this, as above shown, only 300,000l. will in all probability be required. The Company have the light of taking, without any payment, during the first four years, a much of the sewage as they can utilise. From this source an immediate return may be obtained, so that the return upon capital during construction should be much in excess of the interest provided. On payment on the 2nd October next of the 101. per certificate then due. the certificates of 100l. will be exchanged for registered shares of 101. each. According to the calculations made the eventual revenue of the Company is estimated at about 720,000l., and the working expenses and management at 50,0001. Applications in the annexed form should be left with the bankers, who will not, however, receive any applications unless accompanied by a deposit of 21. per certificate on the number of certificates applied for. In cases where no allotment is made the deposit will be returned in full, and should a smaller number than is applied for be allotted the balance returnable to the applicant will be applied towards payment of the amount due on allotment. In cases where an allotment is made the deposit paid on application will be liable to forfeiture if the balance due on allotment be not paid within the term fixed by the letter of allotment and the allotment will be liable to cancellation. Default by subscribers in due payment of the 101. per scrip certificate, payable on 2nd October, 1865, will in like manner render the scrip certificates subject to cancellation, and the amount theretofore paid thereon to forfeiture. Prospectuses and forms of application may be obtained from the bankers and brokers, and at the offices of the Company, No. 60, Threadneedle-street, E.C., London. "The referees are of opinion that there are no objections in an engineering point of view, and that the estimat is suffieien:," The referees were M. D. Hassard, Esq., M.P.; Sir William Gibson Craig, Bart.; and C lonel Stuart, M.P. The proposed undertaking was then inquired into by a select committee of the House, who received a special instruction from the House to "inquire into tha m at useful and profitable means for disposing of the metropolitan sewage on the north side of the Thames." After a long and patient inquiry, the committee summed up their report as follows:-" Upon the evidence, your committee are of opinion that the scheme hich has been submitted to them is a useful and profitable mode of applying the sewave of the northern portio of the metropolis, and they have no reason to suppose that any more useful or profitable scheme could be devised." The committee consisted of the Judge Advocate General. Mr. Avrton, Dr. Prady, Mr. Clay, Mr. Knight, Mr. Taverner, John Miller, Mr. Paget, Mr. Belater Booth, Colonel Smyth, and Mr. Turner. In the discussion which ensued on the presentation of the report to the House, Sir George Grey and Mr. Henley both expressed their approval of the scheme. The scheme was again inquired into very fully by a committee of the House of Lords, where the bill passed through all the different stages, and laving received the royal assent is now an Act of Pa liament, and has become law On the division in the House of ords upon the third reading, 49 peers voted in favour of the bill, and only four against it, his Royal Highness the Prince of Wales being one of the 49, and giving to this bill the countenane and support of his first vote ever recorded in the House of Lords. Of the value of sewage as a manure, there is, as stated in a leading article upon this scheme. published in the Times ofthe 2nd March last, no dispute." The only question in regard to the sewage of Londen eing, as the Times says, whet' er that value is "400,000 or 4,000.000l. a year." This latter figure is the estim te of Baron Liebig and the Corporation of the City of London for the sewage of both sides of the metropolis; or roughly. about 2 666,6661., a the yearly value of that porti n of the sewage which has become the property of the Company by virtue of their agreement with Messrs. Napier and Hope, but the direc ors concur with these gentlemen in believing that this estimate is greatly exaggerated. However, the culvert which the directors have contracted for is of an internal diameter of 10 ft., instead of 9 ft. 6 in.; and by means of the greater carrying power thus obtained, together with the means at their disposal for storing the sewage in the reservoirs of the Metropolitan Board, they will be enabled to utilise at least 120 000.000 tons of sewage per annum, and from this they look for an eventual net profit to be divided with the Board of upwards of WATER POISONED BY LEADEN PIPES "The above engraving represents accurately a section of a leaden pipe, which was employed for a short time in conveying water from a well on the grounds of Mr. Dick, of Bonchurch, Isle of Wight. The water has cut these deep pits almost through the pipe, and not only upon the portion which we have illustrated, but has formed similar chasmi throughout the entire length."-Expositor. POISONED WATER PREVENTIBLE BY THE USE OF GUTTA-PERCHA TUBING. The Gutta Percha Company have been favoured with the following letter: From DR. MURRAY, Hull. "It is impossible to conceive of anything more injurious or destructive to the health of the community than the use of leaden pipes for the conveyance of water The poisonous salts of lead thereby communicated are most insidious and subtle. I hail with gratitude the substitution of Gutta Percha Tubing. I have had the leaden pipe of my own house removed, and its place supplied with one of Gutta Percha. Nothing can be better. I have also recommended it to others, who have adopted the expedient." RESISTANCE OF FROST. The Gutta Percha Company have been favoured with the following Letters in reference to the non conducting properties of Gutta Percha Tubing in the resistance of Frost: From J. ARMSTRONG, Esq., M.D., Gravesend. "My private house, which was supplied with your Gutta Percha Tubing some five or six years ago, has never required the sligutest attention; winter passed that we were not deluged in consequence of and previously, there was no the bursting of the leaden pipes." From HENRY BROWN and SONS, Western Works, 108, Rockingham-street, Sheffield. "We have now a positive proof of the frost-resisting properties of the Gutta Percha Piping. On our premises we have a leaden Pipe and a Gutta Percha one lying side by side. The leaden one has been completely frozen up at least ten days, and the Gutta Percha one is still unaffected." tions are fully developed and in full working the return from the EVERY VARIETY of GUTTA PERCHA ARTICLES Company's own land should be not less than 216,000l. and this would absorb 35 millions of tons of sewage, leaving 85 millions available for sale to the farmers along the line of culvert, which, in the same ratio of value, would produce not less than 510,000l. a year, making a total of 720.0001.; and this figure is singular y borne out by the experience and opinions of those most conversant with the MILL BANDS subject, and is quite within the estimates given in evidence before the Houses of Parliament. One farmer. Mr. Wagstaff, of South Oxendon, who farms 1.200 acres on the line of culvert, stated upon oath that he would be prepared to give 2d. per ton for such quantities of the sewage as it suited him to take a value strongly SOLES insisted upon by many high authorities; at which rate the yearly value of the whole would be no less than one million sterling. Another rugh estimate of the realisable value of sewage which has been given in evidence by many authorities, namely, one penny per ton all round, would produce 500,000l. a year. 80 that the estima ed return of 720,000l. arrived at by independent FIRE-BUCKETS calculations is as near as possible the mean between these two SHEET |
