erect, with its attracting end towards the earth, the island descends; but when the repelling extremity points downwards, the island mounts directly upwards. When the position of the stone is oblique, the motion of the island is so too: for in this magnet, the forces always act in lines parallel to its direction.

By this oblique motion, the island is conveyed to different points of the monarch's dominions. To explain the manner of its progress, let A B represent a line drawn across the dominions of Balnibarbi, let the line c d represent the loadstone, of which let d be the repelling end, and c the attracting end, the island being over C: let the stone be placed in position c d with its repelling end downwards; then the island will be driven upwards obliquely towards D. When it is arrived at D, let the stone be turned upon its axle, till its attracting end points towards E, and then the island will be carried obliquely towards E; where, if the stone be again turned upon its axle till it stands in the position E F, with its repelling point downwards, the island will rise obliquely towards F, where, by directing the attracting end towards G, the island may be carried to G, and from G to H, by turning the stone so as to make its repelling extremity point directly downward. And thus by changing the situation of the stone, as often as there is occasion, the island is made to rise and fall by turns in an oblique direction, and by those alternate risings and fallings (the obliquity being not considerable) is conveyed from one part of the dominions to the other.

But it must be observed, that this land cannot move beyond the extent of the dominions below, nor can it rise above the height of four miles. For which the astronomers (who have written large systems concerning the stone) assign the following reason: that the magnetic virtue does not extend beyond the distance of four miles, and that the mineral, which acts upon the stone in the bowels of the earth, and in the sea about six leagues distant from the shore, is not diffused through

the whole globe, but terminated with the limits of the king's dominions; and it was easy, from the great advantage of such a superior situation, for a prince to bring under his obedience whatever country lay within the attraction of that magnet.

When the stone is put parallel to the plane of the horizon, the island stands still; for in that case the extremities of it, being at equal distance from the earth, act with equal force, the one in drawing downwards, and the other in pushing upwards, and consequently no motion can ensue.

This loadstone is under the care of certain astronomers, who, from time to time, give it such positions as the monarch directs. They spend the greatest part of their lives in observing the celestial bodies, which they do by the assistance of glasses, far excelling ours in goodness. For, although their largest telescopes do not exceed three feet, they magnify much more than those of a hundred with us, and shew the stars with greater clearness. This advantage has enabled them to extend their discoveries much farther than our astronomers in Europe; for they have have made a catalogue of ten thousand fixed stars, whereas the largest of ours does not contain above one-third part of that number. They have likewise discovered two lesser stars, or satellites, which revolve about Mars; whereof the innermost is distant from the centre of the primary planet exactly three of his diameters, and the outermost, five; the former revolves in the space of ten hours, and the latter in twenty-one and a half; so that the squares of their periodical times are very near in the same proportion with the cubes of their distance, from the centre of Mars; which evidently shews them to be governed by the same law of gravitation that influences the other heavenly bodies.

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 parts of astro

nomy.

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 lie all 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 consists, 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 apprized, 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.

CHAPTER IV.

The Author leaves Laputa; is conveyed to Balnibarbi; arrives at the metropolis -A description of the metropolis, and the country adjoining-The Author hospitably received by a great lord-His conversation with that lord.

ALTHOUGH I cannot say that I was ill treated in this island, yet I must confess I thought myself too much neglected, not without some degree of contempt; for neither prince nor people appeared to be curious in any part of knowledge, except mathematics and music, wherein I was far their inferior, and upon that account very little regarded.

On the other side, after having seen all the curiosities of the island, I was very desirous to leave it, being heartily weary of those people. They were indeed excellent in two sciences for which I have great esteem, and wherein I am not unversed; but at the same time, so abstracted and involved in speculation, that I never met with such disagreeable companions. I conversed only with women, tradesmen, flappers, and court-pages, during two months of my abode there, by which, at last, I rendered myself extremely contemptible; yet these were the only people from whom I could ever receive a reasonable answer.

I had obtained, by hard study, a good degree of knowledge in their language: I was weary of being confined to an island, where I received so little countenance, and resolved to leave it with the first opportunity.

There was a great lord at the court, nearly related to the king, and for that reason alone used with respect. He was
