They have observed ninety-three different comets, and settled their periods with great exactness. If this be true (and they affirm it with great confidence) it is much to be wished, that their observations were made public, whereby the theory of comets, which at present is very lame and defective, might be brought to the same perfection with other arts of astronomy.
The king would be the most absolute prince in the universe, if he could but prevail on a ministry to join with him; but these having their estates below on the continent, and considering that the office of a favourite has a very uncertain tenure, would never consent to the enslaving of their country.
If any town should engage in rebellion or mutiny, fall into violent factions, or refuse to pay the usual tribute, the king has two methods of reducing them to obedience. The first and the mildest course is, by keeping the island hovering over such a town, and the lands about it, whereby he can deprive them of the benefit of the sun and the rain, and consequently afflict the inhabitants with dearth and diseases: and if the crime deserve it, they are at the same time pelted from above with great stones, against which they have no defence but by creeping into cellars or caves, while the roofs of their houses are beaten to pieces. But if they still continue obstinate, or offer to raise insurrections, he proceeds to the last remedy, by letting the island drop directly upon their heads, which makes a universal destruction both of houses and men. However, this is an extremity to which the prince is seldom driven, neither indeed is he willing to put it in execution; nor dare his ministers advise him to an action, which, as it would render them odious to the people, so it would be a great damage to their own estates, which all lie below; for the island is the king's demesne.
But there is still indeed a more weighty reason, why the kings of this country have been always averse from executing so terrible an action, unless upon the utmost necessity. For, if the town intended to be destroyed should have in it any tall rocks, as it generally falls out in the larger cities, a situation probably chosen at first with a view to prevent such a catastrophe; or if it abound in high spires, or pillars of stone, a sudden fall might endanger the bottom or under surface of the island, which, although it consist, as I have said, of one entire adamant, two hundred yards thick, might happen to crack by too great a shock, or burst by approaching too near the fires from the houses below, as the backs, both of iron and stone, will often do in our chimneys. Of all this the people are well apprised, and understand how far to carry their obstinacy, where their liberty or property is concerned. And the king, when he is highest provoked, and most determined to press a city to rubbish, orders the island to descend with great gentleness, out of a pretence of tenderness to his people, but, indeed, for fear of breaking the adamantine bottom; in which case, it is the opinion of all their philosophers, that the loadstone could no longer hold it up, and the whole mass would fall to the ground.
By a fundamental law of this realm, neither the king, nor either of his two eldest sons, are permitted to leave the island; nor the queen, till she is past child-bearing.
