From Roy Chapman Andrews' excellent book 'Across Mongolian Plains' published in 1921.
Our way led close along the Tola River, and just before tiffin we saw a line of camels coming diagonally toward us from behind a distant hill. I wish you could have seen that caravan in all its barbaric splendor as it wound across the vivid green plains. Three lamas, dressed in gorgeous yellow robes, and two, in flaming red, rode ahead on ponies. Then neck and neck, mounted on enormous camels, came four men in gowns of rich maroon and a woman flashing with jewels and silver. Behind them, nose to tail, was the long, brown line of laden beasts. It was like a painting of the Middle Ages — like a picture of the days of Kublai Khan, when the Mongol court was the most splendid the world has ever seen. My wife and I were fascinated, for this was the Mongolia of our dreams.
Like the trained units of an army each camel came into position, kneeled upon the ground and remained quietly chewing its cud until the driver removed the load. Long before the last straggler had arrived the tents were up and a fire blazing, and far into the night the thirsty beasts grunted and roared as the trough was filled with water. For thirty-six days they had been on the road, and yet were only halfway across the desert. Every day had been exactly like the day before — an endless routine of eating and sleeping, camp-making and camp- breaking in sun, rain, or wind. The monotony of it all would be appalling to a westerner, but the Oriental mind seems peculiarly adapted to accept it with entire contentment.
