JASON, 24th November.

This morning, at six o'clock, we breakfasted, together with Captain Estrada, the commander of the Jason, at the Casa H—-a; and the wind being fair, repaired shortly after in volantes to the wharf, accompanied by our hospitable host, and several of our acquaintances; entered the boat, looked our last of the Palace and the Yntendencia, and of Havana itself, where we had arrived as strangers, and which now, in fifteen days, had begun to assume a familiar aspect, and to appear interesting in our eyes, by the mere force of human sympathy; and were transported to the ship, where a line of marines, drawn up to receive us, presented arms as we entered. The morning was beautiful; little wind, but fair. We took leave of our friends, waved our handkerchiefs to the balconies in return for signals from scarcely-distinguishable figures, passed between the red-tinted Cabana and the stately Morro, and were once more upon the deep, with a remembrance behind, and a hope before us. Our Bergantina is a handsome vessel, with twenty-five guns, five officers, a doctor, chaplain, and purser, and one hundred and fifty men.

We find the commander very attentive, and a perfect gentleman, like almost all of his class, and though very young in appearance, he has been twenty-nine years in the service.

25th.—The weather delightful, and the ship going at the rate of five knots an hour. The accommodations in a brig not destined for passengers are of course limited. There is a large cabin for the officers, separated by a smaller one, belonging to the captain, which he has given up to us.

At seven o'clock C—-n rises, and at eight, a marine sentinel, transformed into a lady's page, whom we are taking to Mexico as porter, brings us some very delicious chocolate. He is followed by the Captain's familiar, an unhappy-looking individual, pale, lank, and lean, with the physiognomy of a methodist parson, and in general appearance like a weed that has grown up in one night. He tremblingly, and with most rueful countenance, carries a small plate of sugar-biscuits. These originals having vacated the cabin, I proceed to dress, an operation of some difficulty, which being performed tant bien que mal, I repair upstairs, armed with book and fan, and sit on deck till ten o'clock, when the familiar's lamentable announcement of breakfast takes us down again. The cook being French, the comestibles are decidedly good, and were the artist a little less of an oil, and more of a water painter, I individually would prefer his style. We have every variety of fish, meat, fowl, fruit, dulces, and wines.

A very long interval has to be filled up by reading, writing, sitting, or walking upon deck, as suits the taste of the individual, or by drinking orangeade, or by sleeping, or by any other ingenious resource for killing time. At five, dinner, at which no one joins us but the captain and one officer; and after dinner on deck till bed-time, walking about, or gazing on the sky or sea, or listening to the songs of the sailors.

26th.—Little wind, but a day of such abominably cruel "balances," as they call them, that one is tempted to find rest by jumping overboard. Everything broken or breaking. Even the cannons disgorge their balls, which fall out by their own weight.

28th.—We have had two days of perfect weather though very warm; the sky blue, without one cloud. To-day we are on the sound, and have lain to, about noon, to let the sailors fish, thereby losing an hour or so of fair wind, and catching a preposterous number of fish of immense size. The water was so clear, that we could see the fish rush and seize the bait as fast as it was thrown in. Sometimes a huge shark would bite the fish in two, so that the poor finny creature was between Scylla and Charybdis. These fish are called cherne and pargo, and at dinner were pronounced good. At length a shark, in its wholesale greediness, seized the bait, and feeling the hook in his horrid jaw, tugged most fiercely to release himself, but in vain. Twelve sailors hauled him in, when, with distended jaws, he seemed to look out for the legs of the men, whereupon they rammed the butt-end of a harpoon down his throat, which put a stop to all further proceedings on his part. He was said to be quite young, perhaps the child of doting parents. The juvenile monster had, however, already cut three rows of teeth.

We are sometimes amused in the evening, when upon deck, by a little drummer, who invariably collects all the sailors round him, and spins them long, endless stories of his own invention, to which they listen with intense interest. On he goes, without a moment's hesitation, inventing everything most improbable and wonderful; of knights and giants and beautiful princesses, and imprisoned damsels, and poor peasants becoming great kings. He is a little ugly, active fellow, with a turned-up nose, a merry eye, and a laughing mouth. Amongst his axioms is the following verse, which he sings with great expression.

Hasta los palos del monte
Tienen su destinacion
Unos nacen para santos
Y otros para hacer carbon.
