We were also shown some ticks. They are the pests of Africa. They exist nearly every place and carry a particularly malicious germ that gives one "tick fever." It is not a deadly fever, but it is recurrent and weakening. There are all kinds of ticks, from little red ones no bigger than a grain of pepper to big fat ones the size of a finger-nail, that are exactly the color of the ground. They seem to have immortal life, for they can exist for a long time without food. Doctor Ward told us of some that he had put in a box, where they lived four years without food or water. He also told us of one that was sent to the British museum, put on a card with a pin through it, and lived over two years in this condition. It is assumed, however, that it sustained fatal injuries, because after a two years' fight against its wound it finally succumbed.
We were told to avoid old camping grounds while on safari, because these spots were usually much infested with ticks waiting for new camping parties. Wild game is always covered with ticks and carries them all over the land. As you walk through the grass in the game country the ticks cling to your clothes and immediately seek for an opening where they may establish closer relations with you. Some animals, like the rhino and the eland, have tick birds that sit upon their backs and eat the ticks. The egrets police the eland and capture all predatory ticks, while the rhino usually has half a dozen little tick birds sitting upon him.
However, we were starting out in a day or so, and in a few days expected to learn a lot more about ticks than we then knew.
It is supposed to require a certain amount of nerve to go lion shooting. It is also supposed to require an additional amount to face an angry rhino or to attempt to get African buffalo. The last-named creature is a vindictive, crafty beast that is feared by old African hunters more than they fear any other animal. In consequence of these dangers we decided that it might be well to give our nerves a thorough test before going out with them. If they were not in good condition it would be well to know of it before rather than after going up against a strange and hostile lion.
That is why we went up in the balloon in Nairobi. The balloon was one of the two Boyce balloons and had never been tried. It was small, of twelve thousand cubic feet capacity, as compared with the seventy thousand foot balloons that do the racing. It was also being tried at an altitude of over five thousand feet under uncertain wind and heat conditions, and so the element of uncertainty was aggravated. We felt that if we could go up in a new balloon of a small size it might demonstrate whether we should later go up a tree or stand pat against a charging menagerie.
There was a great crowd gathered on the hill where this balloon was being inflated. Since five o'clock in the morning the gas had been generating in the wooden tanks, and from these was being conducted by a cloth tube to the mouth of the balloon. The natives squatted wonderingly about in a circle, mystified and excited. At three o'clock the balloon was over half filled and was swaying savagely at its anchorage. A strong wind was blowing, and Mr. Lawrence, who had charge of the ascension, was apprehensive. He feared to fill the balloon to its capacity lest the expansion of the gas due to the hot sun should explode it.
At half past three the basket was attached and it looked small—about the size of a large bushel basket, three feet in diameter and three feet deep. The balloon, heavily laden with sand-bags, was lightened until it could almost rise, and in this condition was led across to an open spot sufficiently far from the nearest trees. The crowd thronged up pop-eyed and quivering with excitement. Then there was a long wait until the wind had died down a bit, which it did after a while. The eventful moment had arrived, and Mr. Stephenson, of our party, climbed into the basket. He is only six feet five inches in height and weighs only two hundred and thirty pounds. He had on a pair of heavy hunting boots, for we were leaving for the hunting grounds immediately after the ascension. One by one the restraining bags of sand were taken off, but still the balloon sat on the ground without any inclination to do otherwise.
A wave of disappointment spread over the crowd. Suddenly a brilliant inspiration struck the gallant aëronaut. He took off one of his heavy hunting boots and cast it overboard. The balloon arose a foot or two and then sagged back to earth. Then the other boot was cast over and the balloon rose several feet, swaying and whipping savagely over the heads of the crowd. The wind was now blowing pretty hard, and when the wire was run out the balloon started almost horizontally for the nearest tree, rising slightly.
