aft, on which the ship recover'd her character, and proved the best sailer in the fleet.

The captain said she had once gone at the rate of thirteen knots, which is accounted thirteen miles per hour. We had on board, as a passenger, Captain Kennedy, of the Navy, who contended that it was impossible, and that no ship ever sailed so fast, and that there must have been some error in the division of the log-line, or some mistake in heaving the log.1 A wager ensu'd between the two captains, to be decided when there should be sufficient wind. Kennedy thereupon examin'd rigorously the log-line, and, being satisfi'd with that, he determin'd to throw the log himself. Accordingly some days after, when the wind blew very fair and fresh, and the captain of the paquet, Lutwidge, said he believ'd she then went at the rate of thirteen knots, Kennedy made the experiment, and own'd his wager lost.

The above fact I give for the sake of the following observation. It has been remark'd, as an imperfection in the art of ship-building, that it can never be known, till she is tried,

whether a new ship will or will not be a good sailer; for that the model of a good-sailing ship has been exactly follow'd in a new one, which has prov'd, on the contrary, remarkably dull. I apprehend that this may partly be occasion'd by the different opinions of seamen respecting the modes of lading, rigging, and sailing of a ship; each has his system; and the same vessel, laden by the judgment and orders of one captain, shall sail better or worse than when by the orders of another. Besides, it scarce ever happens that a ship is form'd, fitted for the sea, and sail'd by the same person. One man builds the hull, another rigs her, a third lades and sails her. No one of these has the advantage of knowing all the ideas and experience of the others, and, therefore, cannot draw just conclusions from a combination of the whole.

Even in the simple operation of sailing when at sea, I have often observ'd different judgments in the officers who commanded the successive watches, the wind being the same. One would have the sails trimm'd sharper or flatter than another, so that they seem'd to have no certain rule to govern by. Yet I think a set of experiments might be instituted; first, to determine the most proper form of

the hull for swift sailing; next, the best dimensions and properest place for the masts; then the form and quantity of sails, and their position, as the wind may be; and, lastly, the disposition of the lading. This is an age of experiments, and I think a set accurately made and combin'd would be of great use. I am persuaded, therefore, that ere long some ingenious philosopher will undertake it, to whom I wish success.

We were several times chas'd in our passage, but out-sail'd every thing, and in thirty days had soundings. We had a good observation, and the captain judg'd himself so near our port, Falmouth, that, if we made a good run in the night, we might be off the mouth of that harbor in the morning, and by running in the night might escape the notice of

the enemy's privateers, who often cruis'd near the entrance of the channel. Accordingly, all the sail was set that we could possibly make, and the wind being very fresh and fair, we went right before it, and made great way. The captain, after his observation, shap'd his course, as he thought, so as to pass wide of the Scilly Isles; but it seems there is sometimes a strong indraught setting up St. George's Channel, which deceives seamen and caused the loss of Sir Cloudesley Shovel's squadron. This indraught was probably the cause of what happened to us.

We had a watchman plac'd in the bow, to whom they often called, "Look well out before there," and he as often answered, "Ay, ay"; but perhaps had his eyes shut, and was half asleep at the time, they sometimes answering, as is said, mechanically; for he did not see a light just before us, which had been hid by the studding-sails from the man at the helm, and from the rest of the watch, but by an accidental yaw of the ship was discover'd, and occasion'd a great alarm, we being very near it, the light appearing to me as big as a cartwheel. It was midnight, and our captain fast asleep; but Captain Kennedy, jumping upon deck, and seeing the danger, ordered the ship

to wear round, all sails standing; an operation dangerous to the masts, but it carried us clear, and we escaped shipwreck, for we were running right upon the rocks on which the lighthouse was erected. This deliverance impressed me strongly with the utility of lighthouses, and made me resolve to encourage the building more of them in America if I should live to return there.

In the morning it was found by the soundings, etc., that we were near our port, but a thick fog hid the land from our sight. About nine o'clock the fog began to rise, and seem'd to be lifted up from the water like the curtain at a play-house, discovering underneath, the town of Falmouth, the vessels in its harbor, and the fields that surrounded it. This was a most pleasing spectacle to those who had been so long without any other prospects than the uniform view of a vacant ocean, and it gave us the more pleasure as we were now free from the anxieties which the state of war occasion'd.

I set out immediately, with my son, for London, and we only stopt a little by the way to view Stonehenge' on Salisbury Plain, and
