‘Just,’ he says, ‘as the leading physician of the day may give his services to great numbers of poor patients when these are gathered in a hospital, although he could not practically visit them in their own houses, so the simple fact of a number of clients gathered into a group will enable the leading engineer to give them the benefit of his advice.’
But it was his opinion that only ‘continual supervision could secure the householder from danger due to defects in sanitary appliances.’ He had in his eye a case precisely similar. The following passage in one of his first lectures, afterwards repeated frequently, conveys the essence of Professor Jenkin’s theory, as well as a graceful acknowledgment of the source from which this happy idea was derived:—
‘An analogous case occurred to him,’ he said, ‘in the “Steam Users’ Association,” in Lancashire. So many boilers burst in that district for want of inspection that an association was formed for having the boilers under a continual course of inspection. Let a perfect boiler be bought from a first-rate maker, the owner has then an apparatus as perfect as it is now sought to make the sanitary appliances in his house. But in the course of time the boiler must decay. The prudent proprietor, therefore, joins the Steam-boiler Association, which, from time to time, examines his boiler, and by the tests they apply are able to give an absolute guarantee against accident. This idea of an inspection by an association was due,’ the lecturer continued, ‘to Sir William Fairbairn, under whom he had the honour of serving his apprenticeship.’ [288] The steam users were thus absolutely protected from danger; and the same idea it was sought to apply to the sanitary system of a house.
To bring together a sufficient number of persons, to form such a ‘group’ as had been contemplated, was the first step to be taken. No time was lost in taking it. The idea hitherto roughly blocked out was now given a more definite form. The original sketch, as dictated by Jenkin himself, is before me, and I cannot do better than transcribe it, seeing it is short and simple. Several important alterations were afterwards made by himself in consultation with one or two of his Provisional Council; and as experience suggested:—
‘The objects of this Association are twofold.
‘1. By taking advantage of the principle of co-operation, to provide its members at moderate cost with such advice and supervision as shall ensure the proper sanitary condition of their own dwellings.
‘2. By making use of specially qualified officers to support the inhabitants and local authorities in enforcing obedience to the provisions of those laws and by-laws which affect the sanitary condition of the community.
‘It is proposed that an Association with these objects be formed; and that all residents within the municipal boundaries of Edinburgh be eligible as members. That each member of the Association shall subscribe one guinea annually. That in return for the annual subscription each member shall be entitled to the following advantages:—
‘1. A report by the Engineer of the Association on the sanitary condition of his dwelling, with specific recommendations as to the improvement of drainage, ventilation, &c., should this be found necessary.
‘2. The supervision of any alterations in the sanitary fittings of his dwelling which may be carried out by the advice, or with the approval, of the officers of the Association.
‘3. An annual inspection of his premises by the Engineer of the Association, with a report as to their sanitary condition.
‘4. The right, in consideration of a payment of five shillings, of calling on the Engineer, and legal adviser [290] of the Association to inspect and report on the existence of any infraction or supposed infraction of any law affecting the sanitary condition of the community.
‘It is proposed that the Association should be managed by an unpaid Council, to be selected by ballot from among its members.
‘That the following salaried officers be engaged by the Association:
‘1. One or more acting engineers, who should give their services exclusively to the Association.
‘2. A consulting engineer, who should exercise a general supervision, and advise both on the general principles to be followed, and on difficult cases.
‘3. A legal agent, to be engaged on such terms as the Council shall hereafter think fit.
‘4. A permanent secretary.
‘It is also proposed that the officers of the Association should, with the sanction of the Council, have power to take legal proceedings against persons who shall, in their opinion, be guilty of any infraction of sanitary regulations in force throughout the district; and generally it is intended that the Association shall further and promote all undertakings which, in their opinion, are calculated to improve the sanitary condition of Edinburgh and its immediate neighbourhood.
‘In one aspect this Association will be analogous to the Steam Boiler Users’ Association, who co-operate in the employment of skilled inspectors. In a second aspect it will be analogous to the Association for the Prevention of Cruelty to Animals, which assists the community in enforcing obedience to existing laws.’
Towards the end of November, 1877, this paper was handed about among those who were thought most likely, from their position and public spirit, to forward such a scheme, so clearly for the good of the community. Nay more, a systematic ‘canvass’ was set on foot; personal application the most direct was made use of. The thing was new, and its advantages not perfectly obvious to all at a glance. Everyone who knows with what enthusiastic earnestness Jenkin would take hold of, and insist upon, what he felt to be wholesome and right will understand how he persisted, how he patiently explained, and swept away objections that were raised. One could not choose but listen, and understand, and agree.
On the evening of 2nd January, 1878, or, to be more correct, the morning of the 3rd, two old school-fellows of his at the Edinburgh Academy walked home with him from an annual dinner of their ‘Class.’ All the way in glowing language he expounded his views of house inspection, and the protection of health, asking for sympathy. It was most readily given, and they parted from him with pleasant words of banter regarding this vision of his of grafting ‘cleanliness’ upon another quality said to be a growth, in some sort, of this northern land of ours.
But they reckoned hardly sufficiently on the fact that when Jenkin took a thing of this kind in hand it must be; if it lay within the scope of a clear head and boundless energy.
Having secured a nucleus of well-wishers, the next step was to enlist the sympathies of the general public. It was sought to effect this by a series of public lectures. The first of these (one of two) was given on 22nd January under the auspices of the Edinburgh Philosophical Institution. It was apparent to the shrewd lecturer that in bringing before the people a scheme like this, where there was much that was novel, it was necessary first of all that his audience should be aware of the evils to which they were exposed in their own houses, before unfolding a plan for a remedy. The correspondence already referred to as having been carried on in the summer of the previous year had shown how crude were the ideas of many persons well informed, or considered to be so, on this subject. For example, there are few now-a-days who are not aware that a drain, to be safe, must have at intervals along its course openings to the upper air, or that it must be ‘ventilated,’ as the phrase goes. But at the time spoken of there were some who went so far as to question this principle; even to argue against it; calling forth this forcible reply—’Here is a pretty farce. You pour out a poison and send it off on its way to the sea, and forget that on its way there its very essence will take wings and fly back into your house up the very pipes it but recently ran down.’ A properly ‘trapped’ and ventilated drain was the cure for this.
And the lecturer proceeded to show that in Edinburgh, where for the most part house construction is good and solid, but, as in other towns, the bulk of the houses were built when the arrangements for internal sewerage and water supply were very little understood, many serious errors were made. ‘But,’ the lecturer went on to say, ‘Sanitary Science was now established on a fairly sound basis, and the germ theory, or theory of septic ferments, had explained much which used to be obscure. This theory explained how it was that families might in certain cases live with fair health for many years in the midst of great filth, while the dwellers in large and apparently clean mansions were struck down by fever and diphtheria. The filth which was found compatible with health was always isolated filth, and until the germs of some specific disease were introduced, this dirt was merely injurious, not poisonous. The mansions which were apparently clean and yet fever-visited were found to be those in which arrangements had been made for the removal of offensive matter, which arrangements served also to distribute poison germs from one house to another, from one room to another. These mansions had long suckers extended from one to another through the common sewer. Through these suckers, commonly called “house drains,” they imbibed every taint which any one house in the system could supply. In fact, arrangements were too often made which simply “laid on” poison to bed-rooms just as gas or water was laid on. He had known an intelligent person declare that no harm could come up a certain pipe which ended in a bed-room, because nothing offensive went down. That person had never realised the fact that his pipe joined another pipe, which again joined a sewer, which again whenever there was an epidemic in the neighbourhood, received innumerable poison germs; and that, although nothing more serious than scented soap and water went down, the germs of typhoid fever might any day come up.’
