It is Sunday, the 21st of October. We have to-day observed the people, in the worst quarters of the city as well as in the best, casting their ballots in an orderly and quiet manner, under the supervision of the National Guard, for Victor Emmanuel as their ruler. To-morrow we have set apart for exploring Pompeii, little dreaming what awaits us there. Our friend, General J—n, of the British Army, learning that there is no likelihood of active operations at "the front," proposes to join us in our excursion.

We are seated in the restaurant at the foot of the acclivity which leads to the exhumed city, when suddenly Antonio appears and exclaims, "Garibaldi!" We look in the direction he indicates, and, in an avenue leading from the railway, we behold the Patriot-Soldier of Italy advancing toward us, accompanied by the Countess Pallavicini, the wife of the Prodictator of Naples, and attended by General Turr, with several others of his staff. We go out to meet them. General J—n, a warm admirer of Garibaldi, gives him a cordial greeting, and presents us as an American. We say a few words expressive of the sympathy entertained by the American people for the cause of Italy and its apostle. He whom we thus address, in his reply, professes his happiness in enjoying the good wishes of Americans, and, gracefully turning to our friend, adds, "I am grateful also for the sympathy of the English." The party then pass on, and we are left with the glowing thought that we have grasped the hand of Garibaldi.

Half an hour later, we are absorbed in examining one of the structures of what was once Pompeii, when suddenly we hear martial music. We follow the direction of the sound, and presently find ourselves in the ancient forum. In the centre of the inclosure is a military band playing the "Hymn of Garibaldi"; while at its northern extremity, standing, facing us, between the columns of the temple of Jupiter, with full effect given to the majesty of his bearing, is Garibaldi. Moved by the strikingly contrasting associations of the time and the place, we turn to General J—n, saying, "Behold around us the symbols of the death of Italy, and there the harbinger of its resurrection." Our companion, fired with a like enthusiasm, immediately advances to the base of the temple, and, removing his hat, repeats the words in the presence of those there assembled.

GARIBALDI AT "THE FRONT."

Once again we look in the eye of this wonderful man, and take him by the hand. This time it is at "the front." On Saturday, the 27th of October, we are preparing to leave Naples for Rome by the afternoon boat, when we receive a message from General J—n that the bombardment of Capua is to begin on the following day at ten o'clock, and inviting us to join his party to the camp. Accordingly, postponing our departure for the North, we get together a few surgical instruments, and take a military train upon the railway in the afternoon for the field of action.

Our party consists of General J—n, General W., of Virginia, Captain G., a Scotch officer serving in Italy, and ourself. Arrived at Caserta, Captain G., showing military despatches, is provided with a carriage, in which we all drive to the advanced post at Sant' Angelo. We reach this place at about eight o'clock, when we ride and walk through the camp, which presents a most picturesque aspect, illuminated as it is by a brilliant moon. We see clusters of white tents, with now and then the general silence broken by the sound of singing wafted to us from among them,—here and there tired soldiers lying asleep on the ground, covered with their cloaks,—horses picketed in the fields,—camp-fires burning brightly in various directions; while all seems to indicate the profound repose of men preparing for serious work on the morrow. We pass and repass a bridge, a short time before thrown across the Volturno. A portion of the structure has broken down; but our English friends congratulate themselves that the part built by their compatriots has stood firm. We exchange greetings with Colonel Bourdonné, who is on duty here for the night, superintending the repairs of the bridge, and who kindly consigns us to his quarters.

Arrived at the farm-house where Colonel Bourdonné has established himself, and using his name, we are received with the utmost attention by the servants. The only room at their disposal, fortunately a large one, they soon arrange for our accommodation. To General J—-n, the senior of the party, is assigned the only bed; an Italian officer occupies a sofa; while General W., Captain G., and ourself are ranged, "all in a row," on bags of straw placed upon the floor. Of the merriment, prolonged far into the night, and making the house resound with peals of laughter,—not at all to the benefit, we fear, of several wounded officers in a neighboring room,—we may not write.

Sunday is a warm, clear, summer-like day, and our party climb the principal eminence of Sant' Angelo to witness the expected bombardment. We reach the summit at ten minutes before ten, the hour announced for opening fire. We find several officers assembled there,—among them General H., of Virginia. Low tone of conversation and a restrained demeanor are impressed on all; for, a few paces off, conferring with two or three confidential aids, is the man whose very presence is dignity,—Garibaldi.

Casting our eye over the field, we cannot realize that there are such hosts of men under arms about us, till a military guide by our side points out their distribution to us.

"Look there!" says General H., pointing to an orchard beneath. "Under those trees they are swarming thick as bees. There are ten thousand men, at least, in that spot alone."
