To correct, therefore, all errors of this kind, which are otherwise impossible to detect when the ship is out of sight of land, various observations of the sun, moon, or stars are taken, whereby the exact latitude or longitude (or sometimes both together) of the ship at the moment of observation is ascertained.
This short lesson in navigation over, we will now rejoin the Water Lily, which we left at six p.m. off the Lizard, on the starboard tack.
It was my “eight hours out” that night, and when I took the tiller at eight o’clock we were dashing along a good honest eight knots, under whole canvas and a jib-headed gaff-topsail. The night was as fine as the previous one, but with a little more wind, and we were just beginning to get within the influence of the Atlantic swell. There was no sea on, but the long, majestic, heaving swell was sweeping with stately motion towards the Channel, rising like low hills on either side of us as our little barkie sank between them, and gleaming coldly, like polished steel, where the moon’s rays fell upon their crests. But the little Lily sprang gaily onward upon her course, mounting the watery ridges and gliding down into the liquid valleys with the ease and grace of a sea-bird, and without throwing so much as a drop of water upon her deck.
The serenity and beauty of the night, the brilliancy of the stars which studded the deep purple vault above me, and the gentle murmur of the wind through the cutters rigging, combined to produce a sensation of solemnity almost amounting to melancholy within me, and my thoughts flew back to the beloved sister I had so recently parted with, wondering whether she was at that moment thinking of me, or whether we should ever meet again, and, if so, how long hence and under what circumstances; and so on, and so on, until I was recalled to myself by a sprinkling of spray upon my cheek, whereupon I awoke, in the first place, to the fact that the breeze had so far freshened that the Lily was flying through the water with her lee gunwale pretty well under; and, in the second, to the knowledge that I had outstayed my watch a good half hour.
I lost no time in calling Bob, and as soon as he came upon deck we got our gaff-topsail down and our topmast housed.
I then went below and turned in; but I had time, before leaving the deck, to notice that we went through the water quite as fast (if not a trifle faster), now that our lee gunwale was just awash, as we did when it was buried a couple of planks up the deck in water.
When Bob called me at the expiration of his watch, I found, on going on deck, that the wind had continued to freshen all through the four hours I had been below, and it was now blowing quite a strong breeze. It had gradually hauled round to about north-west, too, which brought it well upon our starboard quarter, and we were flying along at a tremendous pace, with all our sheets eased well off.
But although by this change we were running off the wind, and consequently did not feel its full force, I decided to take down a single reef in the mainsail, and shift the jib; for there was a windy look in the sky that seemed to promise a very strong blow shortly. I did not wish to disturb Bob when perhaps about half way through his four hours’ sleep, so I got him to assist me in making my preparations before he left the deck. And the promise was amply fulfilled as the sun rose higher in the sky, the wind freshening rapidly, but hauling still farther round from the northward as it did so.
By the time that Bob came on deck again, at seven bells, to prepare breakfast, I had my hands full. The sea was fast getting up, and I began to tremble for my spars and gear. The glass had fallen rather suddenly, and altogether there seemed to be every prospect of a regular summer gale.
Bob was of the same opinion as myself in this respect, so we decided to get everything snug and in readiness for the blow before thinking of breakfast.
