If I were you I should lie up for a sleep as soon as I get there.

Remember you will not see my fire till two o'clock.

If you do not see it then you must keep watch till morning, for there's no saying when it may be lit.

As soon as you see it you show a light three times in the direction of the creek.

If you see it answered you will have nothing more to do; if not you must keep on showing the light till you do get an answer.
