ALARMING SUBSIDENCE AT BARRY DOCK. DEEP WATER LOCK DAMAGED. SIDE WALL GIVES WAY. The Entrance Rendered Useless. DOCK MEN PANIC-STRICKEN. THE EXTENT OF THE DAMAGE. Barry lu<k," which n few y.>trR ago was quite a local proverbialism, is "out just now. First there wan the collapse of tbe Yale of Glamorgan viaduct ai Port bkerry-a. very costly matter then there came a dividend luwer than the customary Barry 10 percent., and now a serious misfortune has occurred at the low- water entrance, which has placed the Barry Docks in a position of superiority over all their rivals in the Bristol Channel. At an early hour on Sunday morning it was found that the heavy stonework of the east side of the inner lock had bulged outward, that a cavernous hole about 12 feet in diameter had been made by a subsidence of the earthwork which separates the old basin from the low-wat^r entrance, and that a brick ground-floor building near at band, used by the hydraulic men, had been so rudely disturbed as to produce several zig-zag patterns in the front elevation and to cause one of the doors to fall below its normal level by a few inohes. It was about five o'clock that the first indication of a subsidence was discovered. At this time there were three gatempn. a hydraulic engineer, aud a Board of Trade officer in different rooms of the small brick building. One of these was dozing on the cushion seat when be heard the walls crlick, and suddenly the floor failed beneath him. Bushing out he awoke his com- panions, who went to the hydraulic engineer and the Board of Trade officer's rooms. The last-mentioned—a man named Jenkins—was terror stricken, and called from the inside that he was unable to open his room door. After repeated attempts he got out, and by throwing stones on the tiled roof the hydraulic engineer was awakened. At first none of the men would venture outride, as the earth was in process of gradually subsiding, but after groping in the dark one of them got safely out of the building. It was thought that an earthquake had taken place. A gafeman named Owen ran across the lock to Captain Jones, the deputy dookmaster on duty, and, white with fright, told him that the cabin had fallen in. Captain Jones dis credited the statement as being ridiculous, but on going out the serious nature of the extra- ordinary occurrence became apparent. The water was low in the lock at the time, and a small coasting steamer, the Test, was awaiting to enter. The vessel was stopped, and the gates having been closed water was sluiced into the lock to prevent tbe wall on the east side in front of the sunken ground from falling in. OFFICIALS QUICKLY ON THE SOBHE. The company 8 omeiais, ]j £ r j, Bell, tbe resident engineer; Mr Waddel] his chief assistant; Captain R. Davies, the doo/fema^er and Mr J. H. Hosgood, locomotive superin- tendent, were early on the scene, the whole staff of engineers beii g alxo summoned. Every precaution was taken to prevent any person from going over the subsided ground, and the stuff of nock police were kept busily engaged until barriers had been erected to safeguard tbe general public, who, in the course of the day, visited the scene in bundrerts. A rumour had farly got abroad that tbe lock bad actually collapsed, and the wildest excitemfnt prevailed unril the exact nature of tbe occurrence was ascertained. Many persons travelled from Cardiff and Penarth to learu the exact factb of tbe case. SURVEYING THE DAMAGE. Mr Bell and bis staff were busily engaged for a couple of hours in tbe morning in surveying the damage, with the object of ascertaining, if possible, its extent. It was found that the ground had subsided about two feet, and that the wall of the lock, consisting of huge blocks of stone, had been forced forward above the high water mark exactly 15 inches. Until the water in the lock has been run out it cannot be known whether the wall now submerged has suff- red in the same degree at the bottom, and nothing can consequently be known as to the extent of the damage, which, in any case, is admitted to be very great indeed. THE CAUSE UNKNOWN. In the course of a conversation with one of our representatives Mr Bell said it was impos- sible at the present time to say what was the cause of the subsidence. A slight cavity far beneath tbe surface of tbe ground ruigbt account for it, but there are so many other possible causes that to offer any theory would be idle. It is true that a spring was found at the bottom of the lock at the time of its construction, but, as far as can be judged, tbe subsidence is a good distance from that spring. Every precaution was taken at the time of construction against any damage being done by this spring, which comes up at the bottom of the lock. INTERVIEW WITH THE GENERAL MANAGER. Seen by one of our reporters, Mr Richard Evans, the general manager of the Barry Rail- way Company, said the subsidence was a great misfortune, and might take months to rectify. Asked as to tbe probable cause, Mr Evans said he would not pretend to even conjecture. This was a matter for bir John Wolfe Barry, the designer of the docks aud consulting engineer to the company, to decide after consultation with Mr Bell and other specialists. Bore holes would probably be driven to ascertain the nature and extent of the subsidence, and only after this had been done would it be wise to say anything as to the remedy. In the meantime, of course, the company would revert to tbe method of working the traffic of the docks by means of the old entrance. CONSTRUCTION OF THE LOOKS. The low-water entrance occupied five years in construction, the work being slow in conse- quence of the bed of rock that was encountered from the dock gates to the outer channel. The length of tbe entrance is 647 feet, and 65 fefet wioe, and is divided into two locks. Apparently the OHter or seaward, lock is unaffected by tbe 1an" subsidence. It is the east sJde of the inner lock that effected. All the gates remain in working order. The fact that the deep-water lock entrance had a rt ck foultdatlOn was considered a piece of good fortune, for, although it added largely to the c. st. it was expected to ensure a degree of stability far in excels of f-nytbing at any other dock in the Channel. The walls and everp pait of the entrance were of a 1 ke enduring character —mawive and thoroughly workmanlike. It iSt therefore, all the more surprising that a defect as grave as it is totally unexpected should manifest itself in so short a time. It is note- worthy that on the Pembrokeshire coast subrid- ences similar to this at Barry Dck are comparatively common. G'eat holes are to be met with on the cliffs, due to the operation of springs or to the in-wash of the sea, the sub- strata being worn away and the surface collapsing to an extraordinary extent. These cavities are startling to the tourist who un- expectedly comes upon them. The presence of one or m(,re springs near the site of the subsdence at Barry Dock suggests the theory that similar disintegrating forces have been in operation here. It is fortunate that the occurrence does not in any way effect the old entrance, and that the traffic of the docks at Barry will be carried on with the characteristic facility for which Barry is famous. It is not at all probable that the deep-water entrance itself is materially inter- fered with, but in any event the officials are wise, while awaiting expert advice, in not incurring any risk until the damaged wall is repaired. WHAT THE GATEMFN DECLARE. One at least of the com party's gatemen de- clared to the deputy dockinaster (Capt. Jones), on duty at the time, that he noticed that the ground outride the door of the cabin had sub- sided somewhat even on Saturday afternoon. Although this was regarded by him at the time as being a trivial matter not worth mentioning, it. clearly indicates that there was some dis- turbance beneath the surface, but whether it was of a terraqueous character cannot for the moment be ascertained. MR BRERETON ON THE SCENE. This eniilient partner of Sir John Wolfe Barry has been on the scene throughout the week making an exhaustive survey of the damage, while diving operations have been conducted with the same object. Nothing has yet been ascertained, how- ever, to indicate the precis extent of the damage, or the probable length of time that will be ( ecupied in restoring it to its former state. Statemeuts have appeared in a less-informed daily local press, but these should be taken cum grano salis until the engineers are in a position to report, which they are certainly not at the present time. In all pro- bability some statement will be made at the meeting of shareholders on Friday.
