“May we not presume that the same principles of hydraulics, as to the advantages of a flow over a semicircular bottom, are as applicable to small drains as to large ones?—More so from the flow of water being smaller; the greater necessity for keeping it in a body to enable it to carry away the common deposit.

“Then there is a proportionate loss in having the private drainage made with flat-bottomed bricks or boards?—Yes, there is proportionate loss from the extra cost of cleansing. Semicircular drains of tiles would be better, and cheaper than brick for private houses.”

Supposing that only one-third of the existing tenements require drainage, the saving of 15 per cent. on the expenditure by the execution of the work by contract under the superintendence of a responsible engineer would be more than 1,500,000l. sterling on the outlay, independently of the difference in efficiency.

The necessity has previously been suggested of spreading the immediate cost over a number of years to make the charge coincident with the benefit. Were it left to the option of individuals to repay the cost at intervals of 20 or 30 years, and charge their tenants, as described in a supposed form of notice to them, which I have appended to illustrate the practical working of such a provision, (allowing them either to defray the whole cost at once, or execute the work themselves, under proper superintendence; if they thought they could execute it cheaper,) the immediate advantages of such improvements would then have some chance of being fairly estimated as against the immediate cost and inconveniences of a change, and resistance from latent motives of hostility would be obviated.

But however the charge may be diffused, and to whatever extent opposition on the part of the smaller owners may be obviated by care, it cannot safely be overlooked that in the poorest districts where it is most important that the works should be well executed, the superior direction of such expenditure will, in the ordinary course, fall into the hands of the owners of the worst-conditioned tenements, who have the greatest dread of immediate expenses, and who are under the strongest influence of petty jealousies; for in such districts it is precisely the class of persons who cannot agree to profitable measures of private drainage, who are the owners of the worst tenements, who, having leisure during the intervals of their weekly collections, and from other causes, are most frequently found in honorary offices for the direction of local expenditure. One officer, when asked how it was that in a district where fever had been rife nothing had been done under the authority of the law, which authorized its being cleansed? replied, that the Board had made precisely the same objections that were made when the cholera appeared; when it was proposed to cleanse the district, the answer made at the Board was, that “they did not believe it would do any good:” and those of the officers who were landlords of the weekly tenements said, “Why should we disturb and drive away our tenants?” and those who were shopkeepers said, “Why should we frighten away our customers by representing the neighbourhood as unhealthy?” consequently nothing was done.

The legislature, in making demands for such honorary services, has usually proceeded on the theory which views all those who may be called upon to render them, as persons qualified to understand the whole subject intuitively, and having no other interest or views than to perform the services zealously for the common weal; whereas, in the locality they are viewed in a totally different light, not as public officers, but in their private capacities, as owners or tradesmen, competitors for advantages of various kinds. However unjust this impression may frequently be, it is the impression that commonly prevails; and since all of one class cannot have a share in the administration of such funds, others of the same class, whether owners or tradesmen, view the persons exercising the power as rivals, and distrust their administration accordingly. As an owner, one member of a local Board is strongly indisposed to any line of operations that will apparently improve the property of another; and as an owner, too, he is under the strongest jealousy if he proposes or does anything which may appear to benefit his own property at the public expense.

Neither is such distrust as to trustworthiness from skill and adverse private interests confined to the administration of the public works of sewerage and drainage; it is fortified by the example of the local administration of the works of road construction and repair, a branch of administration so inseparably connected with drainage operations, as to justify and require a joint consideration with them.

Witnesses of the most extensive practical experience lay the greatest stress on the necessity of lifting these important branches of administration out of the influence of petty and sinister interests, and of doing so by securing the appointment of officers of superior scientific attainments, who (subject to a proper local as well as general control) may be made responsible for directing any new expenditure on a scale of efficiency as well as of economy. A competent, scientific, and efficient management, let it be applied to what part of these works it may, can scarcely fail to be immediately as well as ultimately the most economical management. But it will be found on examination that the consolidation of all the structural arrangements, comprising under-drainage and surface-drainage, road structure and repair, under one service, is most required for the sake of efficiency. Division of labour in the arts derives its efficiency from combination, adaptation, and subordination to direction to one end; but that which appears to be a division of labour in local administration is, in fact, an insubordinate separation, weakening the means of procuring adequate skill and power, occasioning obstructions and defective execution, and enhancing expense. Were pins or machines made as sewers and roads are constructed; shafts of pins would be made without reference to heads,—in machines screws would be made without sockets, and, it may be confidently stated, there would not be a safe or perfect and well-working machine in the whole country.

Mr. Telford, in a report on the Holyhead road, makes the following observations:—

“Perfect management must be guided by rules and regulations, and these must be carried into effect by the unceasing attention of a judicious and faithful surveyor who has by actual experience and attention acquired a thorough knowledge of all that is required, and applicable to the general and local state of particular districts, as regards soil, materials, and climate; likewise the sort of wear to which the surface is liable. A person possessed of all these requisites, and otherwise properly qualified to level and set out new lines, &c., where necessary, must receive the remuneration such a character merits, and may always obtain, in this active and industrious country. But however convinced and well-disposed trustees maybe to give this remuneration, the tolls of five or six miles do not afford the means of giving it. The consequence is that the Shifnal Trust (four miles) has hitherto been under the management of a person so little acquainted with proper road business, that it becomes a serious consideration whether it will be prudent to suffer the extensive improvement at Priors Leigh to be entrusted to his care. Until the Parliamentary Commissioners interfered and showed a practical example, the Wellington Trust (seven miles) was managed almost wholly by the clerk; he had a sort of foreman, who appeared to be only partly employed on the road. And on the Shrewsbury Trust (seven miles), as has already been stated, the surveyor and contractor were united in the same person. All these managers proceeded, without regard to any rules and regulations whatever, receiving only occasional directions from some of the most active of the trustees, whose varying opinions served more to distract than benefit the practical operations of the workmen. I must beg leave to add that these observations are applicable to all trusts of similar extent, and are evidences of the propriety of establishing districts of a magnitude to justify a more perfect arrangement, and the employing of a properly qualified surveyor, whose sole occupation should be the road under his care, and who should also be enabled to keep constantly employed a set of workmen thoroughly conversant with road observations, and working chiefly by contract.”—First Annual Report on the Holyhead Road, May 4, 1824. p. 25.
