"I saw what he was at, and called out to him to get out of the way, but instead of this he stuck himself straight before me, stretching himself out like a St. Andrew's cross, with one hand armed with a huge club, and making most diabolical grimaces. Of course the camel was frightened, it was enough to frighten a much more reasonable being; so, wheeling quickly round, it upset my unstable equilibrium. Down I came head foremost to the ground, and when I looked up, my forehead streaming with blood, the first thing I saw was my Arab with the camel, which he seemed mightily pleased with himself for having so cleverly captured, while the servant who had suggested the unlucky experiment came ambling along on my easy-paced dromedary, and consoled me by saying that he knew it was a runaway beast, which there was no riding without a nose-string. "I now began to study the way of keeping one's seat in such an emergency. An Arab, when he gallops his dromedary with one of these saddles, holds hard on with the right hand to the back part of the seat, not to the pommel, and grasps the bridle tightly in the other. The movement of the camel in galloping throws one violently forward, and without holding on, excepting on the naked back, when the rider sits behind the hump, it is impossible to retain one's seat. I afterwards thought myself lucky in not having studied this point sooner, as, from the greater resistance I should have offered, my tumble, since it was _fated_ I should have one, would probably have been much more severe. It is true I might also have escaped it, but in the chapter of probabilities I always think a mishap the most probable." It may be imagined that a fall from a Camel's back is not a trifle, and, even if the unskilful rider be fortunate enough to fall on soft sand instead of hard rock, he receives a tolerably severe shock, and runs no little risk of breaking a limb. For the average height of a Camel's back is rather more than six feet, while some animals measure seven feet from the ground to the top of the hump. Add to this a foot or two caused by the saddle and its cushions, and a height is gained equal to that of the ceiling of many rooms--say, eighteen inches above the top of an ordinary door. This height, however, is of material advantage to the traveller. In the first place it lifts him above the waves of heated air that are continually rolling over the sand on which the burning rays of the sun are poured throughout the day; and in the second place it brings him within reach of the slightest breeze that passes above the stratum of hot air, and which comes to the traveller like the breath of life. Moreover, his elevated position enables him to see for a very great distance, which is an invaluable advantage in a land where every stranger may be a robber, and is probably a murderer besides.
