projecting out, on which cross-planks are placed to bind them together; and so proceeds the work through all the vessels which are required to bridge the river. At each end of this bridge firmly fixed gangways are thrown forward,[667] so that the approach may be safer for the horses and beasts of burden, and at the same time to serve as a bond to the bridge. In a short time the whole is finished with a great noise and bustle; but yet discipline is not relaxed while the work is going on. In each vessel the exhortations of the overseers to the men, or their censures of sluggishness, neither prevent the orders being heard nor impede the rapidity of the work.[668] CHAPTER VIII. MARCH FROM THE INDUS TO THE HYDASPES. This has been the method of constructing bridges, practised by the Romans from olden times; but how Alexander laid a bridge over the river Indus I cannot say, because those who served in his army have said nothing about it. But I should think that the bridge was made as near as possible as I have described, or if it were effected by some other contrivance so let it be. When Alexander had crossed to the other side of the river Indus, he again offered sacrifice there, according to his custom.[669] Then starting from the Indus, he arrived at Taxila, a large and prosperous city, in fact the largest of those situated between the rivers Indus and Hydaspes. He was received in a friendly manner by Taxiles, the governor of the city, and by the Indians of that place; and he added to their territory as much of the adjacent country as they asked for. Thither also came to him envoys from Abisares, king of the mountaineer Indians, the embassy including the brother of Abisares as well as the other most notable men. Other envoys also came from Doxareus, the chief of the province, bringing gifts with them. Here again at Taxila Alexander offered the sacrifices which were customary for him to offer, and celebrated a gymnastic and equestrian contest. Having appointed Philip, son of Machatas, viceroy of the Indians of that district, he left a garrison in Taxila, as well as the soldiers who were invalided by sickness, and then marched towards the river Hydaspes. For he was informed that Porus,[670] with the whole of his army was on the other side of that river, having determined either to prevent him from making the passage, or to attack him while crossing. When Alexander ascertained this, he sent Coenus, son of Polemocrates, back to the river Indus, with instructions to cut in pieces all the vessels which he had prepared for the passage of that river, and to bring them to the river Hydaspes. Coenus cut the vessels in pieces and conveyed them thither, the smaller ones being cut into two parts, and the thirty-oared galleys into three. The sections were conveyed upon waggons, as far as the bank of the Hydaspes; and there the vessels were fixed together again, and seen as a fleet upon that river. Alexander took the forces which he had when he arrived at
