AN OCEANIC PERTURBATION.

'■■ A remarkable fluctuation of the tide occurred yesterday, and attracted a great deal of attention. The pulsation of Old Ocean was, . in fact, quite abnormal/ indicating a feverish restlessness that has not been notice, able here sipce the so-termed, tidal wave; of 1868. This time a disturbance in the waters of the Harbour was first; remarked - about daybreak by fishermen in the pursuit of their calling about the banks. The tide was ob>, served to rapidly recede, and then as suddenly to flow several feet; up the banks. An hour or two srfterwards Mr Fletcher, of Mansford Bay, was astonished to bhserve the watef rapidly ebb away far below spring tide low water mark, exposing the lower part of his slip, which had not been laid bare since the disturbance. of 1868. ; About 9 o'clock a strange tidal turmoU waß noticed, at the pier of the Quarantine Island; Firat the .tide J ebbed, it beiajg then about low water^ and I then it flowed, and so continued rising: and falling from 7in. to ,18inl About half-past -nine o'clock the attention of • the Harbour Master was directed to the tidal fluctuation at the piers, and there, until long past noon, scores of persons we're converted into close observers pf the phenomena. The tide pulsar tions were very apparent, up and down, up and down, and that, too, with a strong flood tide running, the rise sometimes being as much as 15in. to 20!n. in half as many minutes, whilst the ebb was nearly as great. This action and reaction stirred the Harbour to its depths* ahd rendered tbe water quite tnrbid, whilst the vessels at anchor in the stream were slued about by the changing tide, and once the tide, then being strong flood, took quite a half cant to ebb. This was particularly noticed by our representative, who happened to beailoat at the time. . He also timed and measured one of.the pnlsations, and found 'the rise: to' be quite 15ih. in about eight minutes,: whilst the recoil was!about;,9in. in a similar time. A tidal disturbance was

also noticed at the Heads. Telegraphing iri the afternoon to the Harbour Master, Pilot Kelly said that a Btrcng ebb tide was running at Hobart Town Point, whilst the "vessels at anchor and the light-ship were swung at flood. He thought it was caused by the heavy sea on tbe bar. From this it would seem that the fluctuations were-not closely observed at the Heads/which is to be regretted, as they would doubtless have been more decided there. ""'.'.".*.."."

| Napier, May Uth. A special telegram to the Telegraph states that there was a great tidal disturbance all through last night at Gisborne.'. This morning, at a quarter to three o'clock, at threequarter ebb tide, the tidal wave came over the bay and rose Sft above the top ofthe hull of the Go-a head. The men,-to save their own lives, had to fly to the rigging. The wave struck the bar partially ahd broke j .it cevertheless caused a sudden rise in the river of from three to four feet, overflowing the banks on the low-lying portions. At 9.30, a second and a heavy wave ran up the river, causing great alarm. At 9.45, there was another, and almost immediately after? wards a.fourth. The weather is fine/,with a fresh breeze blowing, and the water inthe bay is much agitated. It is supposed to be caused by a subterranean upheaval.

Wellingxow, May llth. ; Since, before S.o'clock this morning a tidal wave was noticed,' its rise and fallbeing abont 4ft, and the action and reaction occupying about fifteen jninutes. It is still going onj but increasing. -At"the reclamation. wprks,! where this water is cdnfinedtp ahuhcomT pleted breastwork, the tide rushed in aud out with a force Wemblirig the tide at the French Pass. '

Cbdsistchuroh, May llth. ; There was a strange tidal disturbance this morning in Lyttelton harbour. From seveii o'clock till this hour (one o'clock) the water has been rising and falling in an unusual manner; at times rising three feet in a few minutes, and falling equally rapidly! N6 damage has been done. It was felt in Waimakariri also, and at Timaru. *

Akaroa, May llth. j A heavy tidal wave was experienced here this; morning—first at seven o'clpck, whenii was nearly dead low water,* The sea came in with great force and receded in five mini utes,the rise andiall being about eight feet; The waves are coming in at intervals of about twenty minutes. No damage is ret ported. ..,,.., ?-■-' !

/.■■,.. v OAMARTT,vMayLIIth. I A curious tidal phenomenon waa experiehcedhere to-day. At low water (about 8 a.m.), the water in the bay rose in aboufcten minutes until within i-on^ foot, of KigE water mark.^ This continued with more or less variation till noon, when;a tidal wave came rushing into the bay. The barque William Gifford broke away from her mooring warpi at the break.'water, and being caught in a strong current and whirlpool, was dashed against; the. inside of the breakwater^ fand then washed towatdß the shore; where' she struck the bottom. Under the abib sbaihani ship of the Harbour Master (Captain Sewell)

she got dear, and put to sea. Throug&i striking the bottom sho commenced to IdaV and an hciur after jshe put.to se3, she had 3 madea foot of water, i She shaped a course for Port: Chalmers. A telegram has-been, sent for a tug to be on the look-out for- heraUMago Heads. The.other vessels at the* Wharf were only slightly damaged about th* ngging through colliding with ono another.lhe Waitaki arrived at the usual time, butthe sea being too heavy, she had to--lay of^f and her passengers were landed by the susT boats.

Kaitangata, May llth. At ten o'clock this morning, a wave about: eighteen inches in height was seen coming upi the river, carrying all small pieces' of: drift wood, &c. f with it, again«t the current and strong south-west wihd^* 'The river rose • to four feet above its former height/-but-receded within twenty minutes. This ewelh?g. has continued hourly up till now-' (2:p.m.). .•:-,, .:.. fig-, .-.'..,.
