called, the Rea was sufficient to carry off the surface waters taken to its channel by the many little rills and brooks of the neighbourhood, but as the town increased, and house drainage defiled that limped stream, it became necessary to construct culverts, so as to take the most offensive portion of the sewage to a distance from inhabited houses. A great improvement was looked for after the introduction of the Waterworks, allowing the use of water- flushed closets in the better class of houses, instead of the old style of accommodation usually provided at the end of the garden, but even this system became a nuisance, especially to residents near the river Tame, the receptacle of all liquid filth from our streets, closets, middens, and manufactories, and legal as well as sanitary reasons forced upon the Corporation the adoption of other plans. Our present sanitary system comprises the exclusion, as far as possible, of closet refuse and animal and vegetable matters from the sewers, and secondly, the purification by filtration, &c., of the outpourings of the sewers, after the partial separation therefrom of the more solid constituents. In 1871, when the real sanitary work of the borough may be said to have practically commenced, out of about 73,200 houses only 3,884 were provided with water-closets, the remainder being served by middens, drained and undrained, the greater part uncovered and polluting the atmosphere, while the soakage found the earth and contaminated the wells. From these places in 1873 there were removed 160,142 loads of ashes, &c., the number of men employed being 146, and the cost, allowing for sales, over £20,000, or £55 10s, per 1,000 of the Population. In the following year the Council approved of " the Rochdale system," closet-pans and ash-tubs taking the place of the old style with middens, the contents being removed weekly instead of being left to accumulate for months. At first the new system was far from perfect, and met with much opposition, notwithstanding the certainty of its being a more healthy plan than the old one; but improvements have been made, and it is now generally confessed that the l)ans and tubs are the right things in the right places. The number of pans in use in 1874 was 3,845; in 1875, 7,674; in 1876, 15,992; in 1877, 22,668; in 1883, 37,287, equal to a collection of 1,900,000 pans per year. The sanitary force now numbers 622 men, who, in addition to the above, removed in 1883, from tubs, middens, &c., 128,966 loads of ashes. The chief depot for this accumulation of refuse and rubbish is at the Corporation's wharf, in Montague Street, where over £52,000 has been laid out in buildings and machinery for its due disposal. At first, nearly two thirds of the mass had to be taken by canal into the country, where it was "tipped," the expense being so heavy that it entailed a loss of about 6s. 6d, per ton on the whole after allowing for that part which could be sold as manure. Now, however, the case is different. Extensive machinery has been introduced, and the contents of the pans are dried to a powder, which finds a good market; the ashes, &;c., are used in the furnaces for the drying process, and the residue therefrom, or clinkers, forms a valuable substance for roadmaking or building purposes, &c., in the shape of concrete, paving flags, mantelpieces, tabletops, and even sepulchral monuments being constructed with it, so that in a short time the receipts will, it is expected, more than balance the expenditure in this department of Local sanitary work. The pollution of the river Tame in past years led to continuous litigation until the year 1877, when, as the result of an exhaustive inquiry, it was determined to form a United Drainage District Board, with powers to construct and maintain intercepting sewers sufficient for carrying the drainage of the whole district, com-
