At that time India was a very important country. Very rare and beautiful things were brought from there, such as silks, gold, pearls, ivory, diamonds, rare woods, and many other costly and useful things. Great companies of men were all the time going and coming overland to and from India, and it took a long time, and was a very expensive way of going. The merchants travelled part of the way on horses and part of the way on camels, and the long caravan would go winding across the desert, and through mountain passes, over the plains, guided by the stars, or resting at night around great fires; and if you could see such a sight now you would think it was a great gypsy camp. Then, oftentimes, people who wished to travel to India, or to the places on the way thither, would join these caravans, as it was much the cheaper and safer way, and so there would be found every kind of people travelling together--Jews, Arabs, Spaniards, Dutch, and many others--all on their way to obtain those wonderful and beautiful things from the East; if you had lived at that time, and had started on a journey to India, it would have been as different from such a journey now as you can imagine. Then, after leaving Europe you would have travelled all the way on the back of a camel; and although these caravans sometimes moved during the day, resting at night, still, much the greater part of the travelling, owing to the heat of the sun, was done in the night-time. About ten o'clock at night you would have heard the sound of the trumpets. This was to tell you that the caravan was about to move on. Then the tents were folded up, the camels loaded with the merchandise, the travellers mounted on their horses or camels, and about midnight, after the third blast from the trumpets, the march would begin. Great kettles of burning pitch would send their flames flashing over the desert, and the men and beasts travelled onward through the night by this ruddy gleam. Sometimes, in the earlier part of the journey, the line of march would lay along the sea, and then the thunder of its waves would be heard mingling with the songs of the slaves and the bells of the camels. Riding across a desert is much like sailing across the sea. There is very little variety. You see the same thing day after day. In sailing, you see the sea and sky, and occasionally a ship's sail; in journeying across a desert you see the sand and sky, sometimes an Arab or two looking wonderingly at the caravan before darting off to their hidden retreats, and more often only the bones of camels and elephants scattered on either side of the route, and dazzling the sight with their white gleam. The only thing that would break in upon the sameness would be the stops at the springs for water and rest, when the sacks of food and wine were unpacked from the camels, and the travellers would alight and stay until the heat of the day was past.
