Autobiography of Sir John Rennie, F.R.S., Past President of the Institute of Civil Engineers / Comprising the history of his professional life, together with reminiscences dating from the commencement of the century to the present time.

by Sir John Rennie

The port of Leghorn consisted of several solid stone piers, which did not appear to be laid out in the most scientific manner, and considerable improvements were in contemplation when I saw it. The great difficulty it has to contend with is the quantity of alluvial matter brought down by the Arno, which spreads along the coast for some distance both to the north and south. This might be obviated by judiciously adopting the principle of open piers, as invented by the Romans, so as to allow the littoral current full scope; this would sweep away the alluvium as fast as it was deposited, and the requisite protection from westerly winds might be easily obtained if the works were constructed on a proper system.

Passing by Carrara, I was much struck by the waste consequent on the clumsy method of working the quarries, and of transporting and loading the blocks. It occurred to me at the time how easy it would be to construct an iron tramway from the quarries to the shore, with a suitable pier furnished with powerful derricks at its termination, and this, with proper machinery for quarrying, all of which would have cost but little, would materially reduce the price of the marble, and consequently increase the demand.

As I passed the magnificent and well-protected Gulf of Spezzia, I thought, “What a splendid site for a naval arsenal!” This idea has now been at least partially carried into effect, and if the works are properly designed and executed, it ought to be one of the finest in Europe.

The morning after my arrival at Genoa I arose early, quite refreshed, and went first to the harbour, which I had always heard was one of the finest works of the kind in the world, and as such my excellent father expected that I should give him a complete account of it. I therefore examined it very minutely, and took great pains in tracing, sketching, and measuring it, when I could do so without being observed, for there was a good deal of jealousy about it. At first sight I was very much struck by the extent and magnificence of the bay, with the fine old town rising like a vast amphitheatre of palaces round it, surrounded by a huge circle of forts which crowned the summits of the hills; and by the great extent and massiveness of the two outer moles, the depth of water enclosed within them being capable of receiving at all times the largest vessels of war. But when I began to examine more narrowly I found that there, was a great error in the design of the main or outer moles. The southern, which was the longest, consisted of two arms, the outer one inclining inward at a considerable angle, whilst the northern mole consisted of a single straight line projecting from the shore in a south-south-west direction, so that the entrance pointed south-south-west, and was consequently exposed to the full effect of the severe gales which blow up the Gulf of Lyons during the winter and autumn months; the consequence is that during severe gales from this quarter a heavy swell sets into the entrance and produces such a strong current throughout the interior of the harbour that vessels in front of the town and under the southern mole can scarcely ride with safety at their moorings. This is a serious defect, and it might be easily remedied, although up to the present I have not heard that anything has been done. In the construction of the works there was nothing particular to find fault with, but there was a serious error committed in the disposal of the sewage; the whole of this was discharged into the harbour, so that in hot weather a most disagreeable effluvia arose in front of the lower part of the town; moreover, it caused the accumulation of a considerable quantity of alluvial matter. This had to be removed by constant dredging, in which convict labour was employed. The alluvium was emptied into lighters and sent out to sea to be discharged. The old arsenal was situated at the south-east corner of the inner harbour; it was quite unequal to the requirements of modern times.

While I was at Genoa an accident occurred by which my old acquaintance the sloop ‘Spry’ was nearly lost. Captain Boswell, having served his time, had been succeeded by another captain, who, contrary to strict rule, had his wife on board. The evening on which the captain had given orders to prepare for sailing there happened to be a grand ball in the town, and the lady persuaded her husband to take her, and defer sailing to the morrow. By this time the ‘Spry’ had left the harbour, and lay at single anchor outside the north mole. During the night a strong gale sprung up from the south. As the ship could not regain her old position the officer in command let go two more anchors, but two cables having parted she dragged her third anchor, and was driven close to the rocks. No assistance could be given from the shore, and, as her position seemed hopeless, the officers and crew took to their boats, and managed to get off in safety. To the astonishment of everybody, however, the last cable held, and the recoil of the waves, so close was she to the rocks, actually prevented her from striking, and so she remained until the gale abated, and the ship was saved. The odd part of it was, that when the crew were about leaving the ship my old friend Dr. Biggar was asleep in the cabin, and when aroused flew into a violent rage, and threw a bootjack at the head of the midshipman who woke him. After several ineffectual attempts, the midshipman was obliged to leave him, and he turned round and slept soundly till the morning. Judge of his surprise when he awoke and found what had happened during the night!

After passing rapidly through France, I embarked from Boulogne, September 23, 1821, in a small packet, during a very strong gale, with about fifty other passengers.

The following day we started with the morning’s tide with about seventy passengers, of whom Colonel Hylton Jolliffe, a friend of my father’s, was one. We left Boulogne about eleven, and reached Dover at 2 P.M.; I directly started by coach for London, and reached my father’s, 27, Stamford Street, the same night. I found him in very bad health, lying upon the sofa in the principal front bedroom; he was glad to see me.

He continued in the same weak state, although in perfect possession of all his great faculties, dictated to me several letters on business, and talked of sundry new works that he was about to undertake, particularly the new London Bridge, and the removal of the old one, which had been for some time under discussion in Parliament; a Bill for this purpose had actually been introduced during the past session, and my father had been requested to prepare a design for it, which he did, and it was very similar to that since executed by myself. My father’s bodily health appeared to decline gradually; he was confined almost to the sofa, and could do little more than walk across the room; in this manner he continued until the 3rd of October. He went to bed as usual, perfectly sensible and composed, and hoped that he would soon be better, as he was most anxious to return to business and make up for lost time. I went to his room on the morning of the 4th of October, and found that a considerable change for the worse had taken place; he seemed to be in much pain, and was walking about the room, evidently scarcely knowing what he was about. I got him into bed, and immediately sent for his physician, Dr. Ainslie, who had known him all his life, but he was unfortunately out of town. The apothecary, Mr. Welbank, came, and we consulted together as to whom we should send for, and ultimately summoned Dr. Roberts, who, although in good practice, had never seen my father, and consequently knew nothing of his constitution or complaints. He did the best he could, but evidently thought the case was very serious. My father lay in bed all day, almost unconscious, although I thought he knew me. I remained with him nearly the whole day, and about five o’clock in the afternoon he appeared to be sinking fast, and breathed very heavily, which alarmed us all excessively. In a short time this ceased, his features began gradually to relax, and he breathed his last at half-past five on the afternoon of the 4th of October, 1821, in the sixty-first year of his age.

The disease which killed my poor father was that of the kidneys and liver, as far as we could ascertain. All my brothers and sisters were assembled round his deathbed. It was a sad, sad sight, and afflicted us most severely; we had, however, the melancholy satisfaction of having done all in our power, though of no avail, to arrest the fatal event. He was universally known and respected; the news of his death spread immediately throughout the town, the public papers were filled with leading articles giving accounts of his public and private life, and everybody deplored his loss. One of the most powerful and touching articles was written by his talented friend Perry, the proprietor of the ‘Morning Chronicle,’ who was then at Brighton in bad health, and died there three months afterwards.
