have a passage cut from Panama to Nombre de Dios in America; but Thuanus and Serres the French historians speak of a famous aqueduct in France, intended in Henry the Fourth's time, from the Loire to the Seine, and from Rhodanus to the Loire. The like to which was formerly assayed by Domitian the emperor, [592]from Arar to Moselle, which Cornelius Tacitus speaks of in the 13 of his annals, after by Charles the Great and others. Much cost hath in former times been bestowed in either new making or mending channels of rivers, and their passages, (as Aurelianus did by Tiber to make it navigable to Rome, to convey corn from Egypt to the city, vadum alvei tumentis effodit saith Vopiscus, et Tiberis ripas extruxit he cut fords, made banks, &c.) decayed havens, which Claudius the emperor with infinite pains and charges attempted at Ostia, as I have said, the Venetians at this day to preserve their city; many excellent means to enrich their territories, have been fostered, invented in most provinces of Europe, as planting some Indian plants amongst us, silkworms, [593]the very mulberry leaves in the plains of Granada yield 30,000 crowns per annum to the king of Spain's coffers, besides those many trades and artificers that are busied about them in the kingdom of Granada, Murcia, and all over Spain. In France a great benefit is raised by salt, &c., whether these things might not be as happily attempted with us, and with like success, it may be controverted, silkworms (I mean) vines, fir trees, &c. Cardan exhorts Edward the Sixth to plant olives, and is fully persuaded they would prosper in this island. With us, navigable rivers are most part neglected; our streams are not great, I confess, by reason of the narrowness of the island, yet they run smoothly and even, not headlong, swift, or amongst rocks and shelves, as foaming Rhodanus and Loire in France, Tigris in Mesopotamia, violent Durius in Spain, with cataracts and whirlpools, as the Rhine, and Danubius, about Shaffausen, Lausenburgh, Linz, and Cremmes, to endanger navigators; or broad shallow, as Neckar in the Palatinate, Tibris in Italy; but calm and fair as Arar in France, Hebrus in Macedonia, Eurotas in Laconia, they gently glide along, and might as well be repaired many of them (I mean Wye, Trent, Ouse, Thamisis at Oxford, the defect of which we feel in the mean time) as the river of Lee from Ware to London. B. Atwater of old, or as some will Henry I. [594]made a channel from Trent to Lincoln, navigable; which now, saith Mr. Camden, is decayed, and much mention is made of anchors, and such like monuments found about old [595]Verulamium, good ships have formerly come to Exeter, and many such places, whose channels, havens, ports are now barred and rejected. We contemn this benefit of carriage by waters, and are therefore compelled in the inner parts of this island, because portage is so dear, to eat up our commodities ourselves, and live like so many boars in a sty, for want of vent and utterance.
