The island of Utopia is in the middle two hundred miles broad, and holds almost at the same breadth over a great part of it; but it grows narrower towards both ends. Its figure is not unlike a crescent: between its horns, the sea comes in eleven miles broad, and spreads itself into a great bay, which is environed with land to the compass of about five hundred miles, and is well secured from winds. In this bay there is no great current, the whole coast is, as it were, one continued harbour, which gives all that live in the island great convenience for mutual commerce; but the entry into the bay, occasioned by rocks on the one hand, and shallows on the other, is very dangerous. In the middle of it there is one single rock which appears above water, and may therefore be easily avoided, and on the top of it there is a tower in which a garrison is kept, the other rocks lie under water, and are very dangerous. The channel is known only to the natives, so that if any stranger should enter into the bay, without one of their pilots, he would run great danger of shipwreck; for even they themselves could not pass it safe, if some marks that are on the coast did not direct their way; and if these should be but a little shifted, any fleet that might come against them, how great soever it were, would be certainly lost. On the other side of the island there are likewise many harbours; and the coast is so fortified, both by nature and art, that a small number of men can hinder the descent of a great army. But they report (and there remains good marks of it to make it credible) that this was no island at first, but a part of the continent. Utopus that conquered it (whose name it still carries, for Abraxa was its first name) brought the rude and uncivilized inhabitants into such a good government, and to that measure of politeness, that they now far excel all the rest of mankind; having soon subdued them, he designed to separate them from the continent, and to bring the sea quite round them. To accomplish this, he ordered a deep channel to be dug fifteen miles long; and that the natives might not think he treated them like slaves, he not only forced the inhabitants, but also his own soldiers, to labour in carrying it on. As he set a vast number of men to work, he beyond all men's expectations brought it to a speedy conclusion. And his neighbours who at first laughed at the folly of the undertaking, no sooner saw it brought to perfection, than they were struck with admiration and terror.
