The steamer kept far out to sea, and very little of the coast between Paita and Callao was visible. Finally, on a misty morning, her head was turned towards the land; passing a high, rocky island on the right, and leaving a low shore on the left, she entered the harbor of Callao, and dropped anchor among a miscellaneous assemblage of steamers and sailing-ships, bearing the flags of at least a dozen foreign nations, together with a liberal array of Peruvian and Chilian craft. The Doctor explained that there is generally a mist hanging over the harbor of Callao in the morning, owing to the condensation of the tropical moisture by the cold current of air sweeping northward from the Antarctic regions. The ships at anchor were revealed through this mist, and so were the towers of the castle that commands the harbor and the town at its base. Beyond the shore was a line of hills backed against the snowy mountains in the distance. The shore formed a pleasing contrast to the one they left at Paita, as it was covered with trees, and indicated a break in the desert that the Doctor had described. The steamer was immediately surrounded by boats, and the boatmen hailed the passengers in a perfect polyglot of languages; they endeavored to make bargains previous to the arrival of the captain of the port, without whose authority the ship could not hold communication with the shore. That official took his time, and made everybody impatient; he was visiting a steamer that had just arrived from the south, and was not disposed to hurry. Frank and Fred relieved the monotony of waiting by studying the outlines of the shore, taking note of the heterogeneous array of boatmen, listening to their appeals for patronage, and attempting a sketch of the fort which defended the city and harbor. But their artistic efforts were so frequently interrupted that the sketches were unsatisfactory, and we are not permitted to reproduce them. "The harbor of Callao is nothing to boast of," said the Doctor, "but it is better than most others on the Pacific coast. The prevailing winds are from the south and southwest, and protection is afforded from those winds by the island of San Lorenzo and the tongue of land where Old Callao stood." "Why was the city moved from its former position?" Fred asked. "What was the difference between Old Callao and the present one?"
