With regard to its strength, when there are so many conspicuous examples of the powers of piles to resist the sea in the most exposed situations, any theoretical illustration would be superfluous. But before notice is taken of the works which have preceded and given rise to the proposed plan, a few instances may be stated, such as the Sheers, the Whittaker, the Gun Fleet, and other beacons on the North Coast; and coming nearer to the point itself, the iron beacon on the Black Rock, near Leith, which is about two miles S.E. from the Trinity Pier, has stood alone for years; North Yarmouth jetty, and the Pier at Ostend, on the opposite coast, remain firm, opposed to the sea from the S.E. and N.W. and require no repair but what arises from the decay of the timber; and at Cronstadt, in the Gulph of Finland, there are batteries erected on piles like so many islands, which have remained there from the time of Peter the Great. It may now be noticed, without entering into so wide a field, that the Trinity Pier, which (although on the same principle) is in all respects a more slender and inferior structure to the proposed Pier for Brighton, was erected during the stormy season of the equinox; and even in its unfinished state, while it was of course less capable of resisting the shock of the sea, it suffered no injury; and since its completion, the following reports will show that its strength and security are beyond all question, and what is of as much importance, its utility has surpassed the most sanguine expectations. Copy of a Report from the Directors of the Trinity Pier Company, dated Leith, Sept. 20, 1821:— “These are to certify, that the Trinity Pier was loaded with 118 Pigs of iron ballast, or upwards of 20 Tons, the same that were sent out by Mr. Crichton for proving the said Pier, and that the above ballast was loaded between the piers regularly placed. And we also certify that there was no interruption to the passengers to and from the Steam Boats that were laying alongside at the time it was so loaded. And we further certify, that under all the circumstances of the case, that the said Pier has undergone a more severe trial or proof than was specified in the agreement with Captain Brown; and that the said Pier is in all respects perfect, and in good order. “Given under our hands at Leith, this 20th day of Sept. 1821. (Signed) “ALEXANDER SCOTT, ALEXANDER STEVENSON, Directors of the Trinity Pier.” Copy of the second Report from the Directors of the Trinity Pier Company, dated Leith, the 16th November, 1821:— “Leith, Nov. 16, 1821. “CAPTAIN SAMUEL BROWN, R.N.
