XVI. The duties of pilots will be taken in turns among those qualified by the Harbour Master. On the 1st of each month a distribution is to be made of the fees received.
XVII.-A fall of the barometer, indicative of bad weather, will be announced by the firing of a gun and the hoisting of a white flag with a red square in the centre at the staff on the Canton wharf. The flag will be replaced by two green lights, hoisted perpendicularly, during the night.
XVIII Shipmasters are specially recommended to see that a clear hawse is always kept, have their sheet anchors ready to let go, and take all other usual precau- tions to insure their vessels against bad weather. The signals made by the Harbour Master are merely precautionary and indicative of a coming storm, the force of which as well as its passage over this port can never be predicted.
XIX. All fishing and tanca boats are to be registered at the Harbour Master's Office and have their number and designation clearly affixed.
XX.-These Regulations shall be printed, and a copy given to captains of vessels coming to Macao.

The flood tide, when regular (which is seldom), runs round Cabreta Point towards the town of Micas; but a little outside of the Point it sets along the land to the north, across tae bay, until it meets the tile from Casing-mɔɔn (or Capshui-moon, “the swift water passag,") above Lintiu, when it flows in a direct channel towards the Bogue. The velocity of the flool tide in Macao Roa Is is about 2 miles in the north- east monsoon ani moderate weather; but when it blows strong from the northward there is no apparent flood. The ebb then runs at the rate of 3 to 3 and 4 miles when the water is falling by the land. The ebb tide sets out from the town of Macao much in the same way as the flood comes in, with the difference of running a little more to the westward along the shore, before it takes the southerly direction; the latter part of this tide is therefore the best time for boats to start for Lintin or Canton, with a contrary wind, as they then get out far enough to have all the flood to work to the northward with.
The tides at Lintin run north and south, or nearly so. The velocity of the ebb in the north-east monsoon when blowing strong is much the same as in Macao Roads; but there is always a perceptible flood of 1 or 1 miles. During the height of the south-west monsoon, the ebb runs at times at the rate of 6 and 61 miles, after heavy rains; at that season the floods are very weak.
* The flood censes rizing at this hour, but the stream in the middle of the river runs up a considerable time longer.
