Prevention the first.--_More lights._ Had I--or any other, a twelvemonth ago, written as much, we should have been "pooh poohed" for our pains; had we been able to advance the matter in the House of Parliament, we should have been told by the Opposition, or the Government, whichever had the economical perplexity at the time, that "the country could not afford any more lights." But "the country" can't, and the people won't afford any more losses like the last one, and therefore now it can be both boldly said and written, that something must and shall be done in the matter. As to the situation of any more lights for the entrance to Port Jackson, no doubt there will be many opinions. The North Head has been mentioned as a site for this leading light, but my own convictions, borne out by the judgment of others of great experience, goes against the North Head _only_ being lighted; and if only one light should be added, that there is another situation preferable. Because every seaman knows that a light on a high cliff in thick rain squalls, which is the weather we have here to dread, is not so easily seen as a light placed a moderate distance above the water's edge. Therefore, if one light only should be added, that light should be placed where the turning point of the entrance takes place--in this case the _low_ point of the South Reef--a red light visible eight miles. And perhaps it would not be at all amiss to say, in the Sailing Directions for the Port of Sydney (a copy of which, by the way, I have not seen for a long time in places of resort for seamen, being very likely out of print), that unless such leading light is seen, no sailing vessel with an east wind at night (coasters excluded) should attempt the entrance without a pilot, as long as she can keep to sea.--Having stumbled upon the word pilot, we may write--
