Hong-kong is a rocky island on the coast of China, and has an excellent harbor, sheltered from most of the winds that blow. The town of Victoria is built at the edge of this harbor, and the streets that lead back from the water are so steep that the effort of climbing them is liable to throw a stranger from the North into a violent perspiration. Fortunately, there is an abundance of sedan-chairs, and any one who wishes to take a promenade may do his walking by hiring a couple of chair-coolies to do it for him. The chairs are everywhere, and it is generally desirable to hire one in order to be rid of the continual applications from those that are unemployed. At the wharf where they landed the Doctor engaged porters to carry the baggage to the hotel, and then took chairs for the transportation of himself and the boys. As they had the afternoon before them, the chairs were kept for making the ascent of the mountain just back of the town, and as soon as the rooms were secured, and a slight lunch had been served, they started on their excursion. At the highest point of the mountain--about eighteen hundred feet above the water-level--there is a signal-station, where all vessels coming into port are announced by means of flags. Our friends were carried along a zigzag road to this station, the coolies stopping every few minutes to rest from the fatigue of ascending a steep road with a burden on their shoulders. At the station they had a view extending a long distance out to sea and over the coast of China, and the mountain was so nearly perpendicular that it seemed as if they could toss a penny on the town or into the harbor. Fred tried it, and so did Frank; but after throwing away several ounces of copper, and finding they only went a short distance, they abandoned the experiment. They returned well satisfied with the excursion, and agreed that no one who visits Hong-kong should omit the journey to the top of the mountain. Hong-kong, being an English colony, is governed after the English form, and consequently the laws enforced in China do not necessarily prevail on the island. The population includes four or five thousand English and other European nationalities, and more than a hundred thousand Chinese. The number of the latter is steadily increasing, and a very large part of the business of the place is in their hands. The money in circulation is made in England for the special use of the colony. It has the head of the Queen on one side, and the denomination and date on the other; and, for the accommodation of the Chinese, the denomination is given in Chinese characters. The smallest of the Hong-kong coins is made to correspond with the Chinese cash, and it takes ten of them to make a cent, or one thousand for a dollar. It has a hole in the centre, like the Chinese coins generally, to facilitate stringing on a wire or cord, and is so popular with the natives that it is in free circulation in the adjacent parts of the empire.
