17.--Beautiful weather. This afternoon all hands were called to shorten sail, in those earnest, startling tones, which are prompted by the sense of danger alone. Every man sprang to his station with the instinctive readiness of disciplined seamen. The idlers were all on deck, and looked about for the cause. Had a man fallen overboard? No! Nor was there any particular appearance of a squall. But the earnest gaze of the commander and a passenger, towards the shore, drew all eyes in the same direction; and, behold! a smoke was seen rising from the land, which had been mistaken for the cloud that precedes the tornado. It is necessary to prepare for many blows that do not come. In the tornado-seasons (which may be estimated at four or five weeks, about the months of March and November), there are frequent appearances of squalls, sometimes as often as twice or thrice in twenty-four hours. The horizon grows black, with very much the aspect of a thunder-shower in America. Generally, the violence of the wind does not equal the apprehensions always entertained. We could have carried royals through nineteen out of twenty of the tornadoes that assailed our ship; but the twentieth might have taken the sticks out of us. The harmless, as well as the heavy tornadoes, have the same black and threatening aspect. They usually blow from the land, although once, while at anchor, we experienced one from seaward. 19.--Anchored at Cape Palmas. This colony is independent, of Liberia proper, and is under the jurisdiction and patronage of the Maryland State Colonization Society. Its title is Maryland in Liberia. The local government is composed of an agent and an assistant agent, both to be appointed by the Society at home, for two years; a secretary, to be appointed by the agent annually; and a vice-agent, two counsellors, a register, a sheriff, a treasurer, and a committee on new emigrants, to be chosen by the people. Several minor officers are appointed by the agent, who is entrusted with great powers. The judiciary consists of the agent, and a competent number of justices of the peace, who are appointed by him, and two of whom, together with the agent, constitute the Supreme Court. A single justice has jurisdiction in small criminal cases, and in all civil cases where the claim does not exceed twenty dollars. Male colored people, at twenty years of age, are entitled to vote, if they hold land in their own right, or pay a tax of one dollar. Every emigrant must sign a pledge to support the constitution, and to refrain from the use of ardent spirits, except in case of sickness. By a provision of the constitution, emigration is never to be prohibited.
