324 I shall conclude the account of this Country with a few observations on the Currents and Tides upon the Coast, because I have mentioned in the Course of this Journal that the latter hath sometimes set one way and sometimes another, which I shall Endeavour to account for in the best manner I can. From the Lat. of 32°, or above downwards to Sandy Cape in the Lat. of 24° 46′, we constantly found a Current setting to the Southward at the rate of 10 or 15 Miles per Day, more or less, according to the distance we were from the land, for it runs stronger in shore than in the Offing. All this time I had not been able to satisfy myself whether the flood-tide came from the Southward, Eastward, or Northward, but judged it to come from the S.E.; but the first time we anchor'd upon the coast, which was in the Lat. of 24° 30′, and about 10 Leagues to the S.E. of Bustard Bay, we found there the flood to come from the N.W. On the Contrary, 30 Leagues further to the N.W., on the S. side of Keppel Bay, we found the Flood to come from the East, and at the Northern part of the said Bay we found it come from the Northward, but with a much Slower Motion than the Easterly Tide. Again, on the East side of the Bay of Inlets we found the flood to set strong to the Westward as far as the Op'ning of Broad sound, but on the N. side of that sound the flood come with a Slow motion from the N.W.; and when at Anchor before Repulse bay we found the flood to come from the northward. We need only admit the flood tide to come from the East or S.E., and then all these seeming Contradictions will be found to be conformable to reason and experience. It is well known that where there are deep Inlets, large Creeks, etc., into low lands, that it is not occasioned by fresh water Rivers; there is a very great indraught of the Flood Tide, the direction of which will be determin'd according to the possition or direction of the Coast which forms the Entrance into such Inlets; and this direction the Tide must follow, let it be ever so contrary to their general Course out at Sea, and where the Tides are weak, as they are in general upon this Coast, a large Inlet will, if I may so call it, attract the Flood tide for many Leagues. Any one need only cast an Eye over the Chart to be made sencible of what I have advanced. To the Northward of Whitsundays Passage there there are few or no large Inlets, and consequently the Flood sets to the Northward or N.W., according to the direction of the Coast, and Ebb the Contrary; but this is to be understood at a little distance from land, or where there is no Creeks or Inlets, for where
