Islands are situated near the centre where the disturbance of the sea level 
originated, and the coast of South Australia as one of the most westerly 
points where it was perceptible, and allowing it the same power, which 
without doubt it possessed, to move as far in an easterly direction, we shall 
then find that its effects were felt over more than ninety degrees of longitude, 
or a fourth of the circumference of the globe. 
From the valuable communication of Captain Gibson, we obtain reliable 
information of what took place in Lyttelton Harbour. It appears that four 
distinct waves, of which the second was the smallest, entered that harbour:

after which only minor disturbances took place. It will also be seen, from 
this list, that the difference in time became less as these waves succeeded 
each other. 
The next bay of which we possess reliable accounts is Pigeon Bay, in 
which Mr. G. H. Holmes has recorded the principal facts. 
Here, the first rush of water entered about 4 o’clock, but no exact time 
was observed, the overseer of Messrs. Holmes and Co. only hearing the 
rumbling noise as if of rushing water. Therefore, we may fix it at the same 
time as it arrived in Lyttelton, 4.30 a.m., rising 4 feet above spring tides. The 
second wave was observed at 7.15 a.m., giving an interval of 2h. 45m. ; the 
rise of water above spring tides was 1 foot. The third rush came at 9.45 a.m., 
giving an interval of 2h. 30m. ; the rise of water above spring tides was 
4 feet. So far, the observations agree with those of Lyttelton Harbour, but 
instead of now only showing minor oscillations, the water continued its rush 
into that smaller bay with even greater velocity. Thus, about midday a 
fifth wave came with still more force and velocity, rising 5 feet. The sixth 
and highest arrived forty minutes later, at 12.40 p-m., rising 7 feet above 
_ Spring tides. And lastly, the seventh, at 1.5 p.m., after which the waves 
diminished considerably, arriving at intervals of three-quarters of an hour. 
These facts are corroborated by Mr. Robert Townsend, District Surveyor, 
who happened to be in Pigeon Bay at the time, and who measured the ver- 
tical height of the water above spring tides. 
Advancing towards the south-east, along the Peninsula, we reach Okain 
Bay, where the earthquake waves were also high and destructive. I owe | 
the information which I possess about that locality to Mr. George Bishop, 
who resides there. This gentleman did not observe the early waves, but
