As the house of Moses was so small, it was not difficult to dispossess them by saturating it with kerosene, which was quickly done, and the little occupant allowed to return and go to bed. He watched the procedure with evident interest, and seemed perfectly aware that I could rid him of his savage assailants. In a wild state he would doubtless have abandoned his claim, and fled to some other place without an attempt to drive them away, but in this instance he had acquired the idea of the rights of possession.
Moses was especially fond of corned beef and sardines, and would recognise a can of either as far away as he could see it. He also knew the instrument used in opening them, but he did not appear to appreciate the fact that when the contents had once been taken out it was useless to open the can again, so he often brought the empty cans that had been thrown into the bush, would get the can-opener down, and want me to use it for him. I never saw him try to open it himself, except with his fingers. Sometimes, when about to prepare my own meals, I would open the case in which I kept stored a supply of canned meats, and allow Moses to select one for the purpose. He never failed to pull out one of the cans of beef, bearing the red and blue label. If I put it back he would select the same kind, and could not be deceived in his choice. It was not accidental, because he would hunt for one until he found it.
I don't know what he thought when it was not served for dinner, as I often exchanged it for another kind without consulting him.
I kept my supply of water in a large jug, which was placed in the shade of the bushes near the cage. I also kept a small pan for Moses to drink out of. He would sometimes ask for water, by using his own word for it. He would place his pan by the side of the jug and repeat the sound a few times. If he was not attended to he proceeded to help himself. He could take the cork out of the jug quite as well as I could. He would then put his eye to the mouth of it, and look down into the vessel to see if there was any water. Of course the shadow of his head would darken the interior of the jug so that he could not see anything. Then removing his eye from the mouth of it, he would poke his hand in it, but I reproved him for this until I broke him of the habit. After a careful examination of the jug he would try to pour the water out. He knew how it ought to be done, but was not able to handle the vessel himself. He always placed the pan on the lower side of the jug; then leaned the jug towards it and let go. He would rarely ever get the water into the pan, but always turned the jug with the neck down grade. As a hydraulic engineer he was not a great success, but he certainly knew the first principles of the science.
I tried to teach Moses to be cleanly, but it was a hard task. He would listen to my precepts as if they had made a deep impression, but he would not wash his hands of his own accord. He would permit me or the boy to wash them, but when it came to taking a bath, or even wetting his face, he was a rank heretic on the subject, and no amount of logic would convince him that he needed it. When he was given a bath, he would scream and fight during the whole process; and when it was finished he would climb up on the roof of the cage and spread himself out in the sun. This was the only occasion on which I ever knew him to get up on the roof. I don't know why he disliked it so much. He did not mind getting wet in the rain, but rather seemed to like that.
He had a great dislike for ants and certain large bugs. Whenever one came near him he would talk like a magpie, and brush at it with his hands until he got rid of it. He always used a certain sound for this kind of annoyance; it differed slightly from those I have described as warning.
Moses tried to be honest, but he was affected with a species of kleptomania, and could not resist the temptation to purloin anything that came in his way. The small stove upon which I prepared my food was placed on a shelf in one corner of the cage, about half-way between the floor and the top. Whenever anything was set on the stove to cook, he had to be watched to keep him from climbing up the side of the cage, reaching his arm through the meshes and stealing it. He was sometimes very persevering in this matter. One day I set a tin can of water on the stove to heat in order to make some coffee; he silently climbed up, reached his hand through, stuck it in the can, and began to search for anything it might contain. I threw out the water, refilled the can, and drove him away. In a few minutes he returned and repeated the act. I had a piece of canvas hung up on the outside of the cage to keep him away. The can of water was placed on the stove for the third time, but within a minute he found his way by climbing up under the curtain between it and the cage. I determined to teach him a lesson. He was allowed to explore the can, but finding nothing he withdrew his hand, and sat there clinging to the side of the cage. Again he tried, but found nothing. The water was getting warmer, but was still not hot. At length, for the third or fourth time he stuck his hand into it up to the wrist. By this time the water was so hot that it scalded his hand. It was not severe enough to do him any harm, but quite enough so for a good lesson. He jerked his hand out with such violence that he threw the cup over, and spilt the water all over that side of the cage. From that time to the end of his life he always refused anything that had steam or smoke about it. If anything having steam or smoke was offered him at the table, he would climb down at once and retire from the scene. Poor little Moses! I knew beforehand what would happen, and I did not wish to see him hurt, but nothing else would serve to impress him with the danger and keep him out of mischief.
Anything that he saw me eat he never failed to beg. No matter what he had himself, he wanted to try everything else that he saw me eat. One thing in which these apes appear to be wiser than man is, that when they eat or drink enough to satisfy their wants they quit, while men sometimes do not. They never drink water or anything else during their meal, but, having finished it, as a rule they always want something to drink. The native custom is the same. I have never known the native African to use any kind of diet drink, but always when he has finished eating takes a draught of water.
Moses knew the use of nearly all the tools that I carried with me in the jungle. He could not use them for the purpose they were intended, and I do not know to what extent he appreciated their use, but he knew quite well the manner of using them. I have mentioned the incident of his using the hammer and nails, but he also knew the way to use the saw; however, he always applied the back of it, because the teeth were too rough, but he gave it the motion. When allowed to have it, he would put the back of it across a stick and saw with the energy of a man on a big salary. When given a file, he would file everything that came in his way; and if he had applied himself in learning to talk human speech as closely and with as much zeal as he tried to use my pliers, he would have succeeded in a very short time.
Whether these creatures are actuated by reason or by instinct in such acts as I have mentioned, the cavillist may settle for himself; but it accomplishes the purpose of the actor in a logical and practical manner, and they are perfectly conscious that it does.
