CHAPTER XIII

OTHER KULU-KAMBAS

Whether the kulu-kamba is a distinct species of ape, or only a

well-marked variety of the chimpanzee, he is by far the finest

representative of his genus. Among those that I have seen are some very

good specimens, and the clever things that I have witnessed them do are

sufficient to stamp them as the highest type of all apes.

On board a small river steamer that plies the Ogowe, was a young female

kulu that belonged to the captain. Her face was not by any means

handsome, and her complexion was the darkest of any kulu I have ever

seen. It was almost a coffee-colour. There were two or three spots much

darker in shade, but not well defined in outline. The dark spots looked

as if they had been artificially put on the face. The colour was not

solid, but looked as if dry burnt umber had been rubbed or sprinkled

over a surface of lighter brown. Although she was young (perhaps not

more than two years old), her face looked almost like that of a woman

of forty. Her short, flat nose, big, flexible lips, protruding jaws

and prominent arches over the eyes, with a low receding forehead,

conspired to make her look like a certain type of human being one

frequently sees. This gave her what is known as a dish-face, or a

concave profile. She had a habit of compressing her nose by contracting

the muscles of the face; curling her lips as if in scorn, and at the

same time glancing at those around her as if to express the most

profound contempt.

Whatever may have been the sentiment in her mind, her face was a

picture of disdain, and the circumstances under which she made use of

these grimaces, certainly pointed to the fact that she felt just like

she looked. At other times her visage would be covered with a perfect

smile. It was something more than a grin, and the fact that it was

used only at a time when she was pleased or diverted, showed that the

emotion which gave rise to it was perfectly in keeping with the face

itself. In repose her face was neither pretty nor ugly. It did not

strongly depict a high mental status, nor yet portray the instincts of

a brute; but her countenance was as safe an index to the mind as that

of the human being. This is true of the chimpanzee more perhaps than of

any other ape. The gorilla doubtless feels the sense of pleasure, but

his face does not yield to the emotion, while the opposite passions are

expressed with great intensity, and with the common chimpanzee it is

the same way, but not to the same extent.

The kulu in question was more of a coquette than she was of a shrew.

She plainly showed that she was fond of flattery. Not perhaps in the

same sense that a human being is, but she was certainly conscious

of approbation and fond of applause. When she accomplished anything

difficult, she seemed aware of it; and when she succeeded in doing a

thing which she was not allowed to do, she never failed to express

herself in the manner described above. She always appeared to be

perfectly conscious of being observed by others, but she was defiant

and composed. There was nothing known in the catalogue of mischief that

she was not ready to tackle at any moment and take her chances on the

result. From the stoke-hole to the funnel, from the jack-staff to the

rudder, she explored that boat.

To keep her out of mischief, she was tied on the saloon deck with a

long line, but no one aboard the vessel was able to tie a knot in the

line which she could not untie with dexterity and ease. Her master, who

was a sailor and an expert in the art of tying knots, exhausted his

efforts in trying to make one that would defy her skill.

On one occasion I was aboard the little steamer when the culprit was

brought up from the main deck where she had been in some mischief,

and tied to one of the rails along the side of the boat. The question

of tying her was discussed, and at length a new plan was devised. In

the act of untying a knot she always began with the part of the knot

that was nearest to her. It was now agreed to tie the line around one

of the rails on the side of the deck, about half-way between the two

stanchions that supported it, then to carry the loose ends of the line

to the stanchion and make it fast in the angle of it and the rail. This

was done. As soon as she was left alone she began to examine the knots;

but she made no attempt at first to untie them except to feel them as

if to see how firmly they were made. She then climbed up on the iron

rail around which the middle of the line was tied, and slackened the

knot. She pulled first at one strand and then at the other, but one

end was tied to the stanchion and the other to her neck, and she could

find no loose end to draw through. First one way and then the other

she drew this noose. She saw that in some way it was connected with

the stanchion. She drew the noose along the rail until it was near the

post; she climbed down upon the deck, then around the post and back

again; she climbed up over the rails and down on the outside, and again

carefully examined the knot; she climbed back, then through between the

rails and back, then under the rails and back, but she could find no

way to get this first knot out of the line. For a moment she sat down

on the deck, and viewed the situation with evident concern. She slowly

rose to her feet and again examined it; she moved the noose back to its

place in the middle of the rail, climbed up by it, and again drew it

out as far as the strands would allow. Again she closed it; she took

one strand in her hand and traced it from the loop to the stanchion,

then she took the other end in the same manner and traced it from the

loop to her neck. She looked at the loop and then slowly drew it out

as far as it would come. She sat for a while holding it in one hand,

and with the other moved each strand of the knot. She was in a deep

study, and did not even deign a glance at those who were watching her.

At length she took the loop in both hands, deliberately put it over

her head and crawled through it. The line thus released dropped to the

deck; she quickly descended, took hold of it near her neck, and found

that it was untied; she gathered it up as she advanced towards the

other end that was tied to the post, and at once began to loosen the

knots about it. In a minute more the last knot was released, when she

gathered the whole line into a bundle, looked at those around her with

that look of contempt which we have described, and departed at once in

search of other mischief. The air of triumph and contempt was enough to

convince any one of her opinion of what she had done.

If this feat was the result of instinct, the lexicons must find another

definition for that word. There were six white men who witnessed the

act, and the verdict of all was that she had solved a problem which few

children of her own age could have done. Every movement was controlled

by reason. The tracing out of cause and effect was too evident for any

one to doubt.

[Illustration: NATIVE VILLAGE AT GLASS GABOON]

Almost any animal can be taught to perform certain feats, but that does

not show the innate capacity. The only true measure of the faculty of

reason is to reduce the actor to his own resources, and see how he will

render himself under some new condition, otherwise the act will be,

at least in part, mechanical or imitative. In all my efforts to study

the mental calibre of animals I have confined them strictly to their

own judgment, and left them to work out the problem alone. By this

means only can we estimate to what extent they apply the faculty of

reason. No one doubts that all animals have minds, which are receptive

in some degree. But it has often been said that they are devoid of

reason, and controlled alone by some vague attribute called instinct.

Such is not the case. It is the same faculty of the mind that men

employ to solve the problems that arise in every sphere of life. It

is the one which sages and philosophers have used in every phase of

science. It differs in degree, but not in kind.

This kulu-kamba knew the use of a corkscrew. This she had acquired

from seeing it applied by men. While she could not use it herself with

success, she often tried and never applied it to the wrong purpose.

She would take the deck broom and scrub the deck, unless there was

water on it, in which event she always left the job. She did not seem

to know the purpose of sweeping the deck, and never swept the dirt

before the broom. This was doubtless imitative. She only grasped the

idea that a broom was used to scrub the deck, but she failed to observe

the effect produced. However, it cannot be said with certainty to what

extent she was aware of the effect, but it is inferred from the fact

that she did not try to remove the dirt.

She knew what coal was intended for, and often climbed into the bunker

and threw it down by the furnace door. The furnace door and steam gauge

were two things that escaped her busy fingers. I do not know how she

learned the danger of them, but she never touched them. She had to be

watched to keep her from seizing the machinery. For this she seemed to

have a strong desire, but did not know the danger she incurred.

I was aboard a ship when a trader brought off from the beach a young

kulu to be sent to England. The little captive sat upright on the deck

and seemed aware that he was being sent away. At any rate his face

wore a look of deep concern as if he had no friend to whom he could

appeal. On approaching him I spoke to him, using his own word for food.

He looked up and promptly answered it. He looked as if in doubt as to

whether I was a big ape or something else. I repeated the sound, and he

repeated the answer and came towards me. As he approached me I again

gave the sound. He came up and sat by my feet for a moment, looking

into my face. I uttered the sound again, when he took hold of my leg

and began to climb up as if it had been a tree. He climbed up to my

neck and began to play with my lips, nose and ears. We at once became

friends, and I tried to buy him, but the price asked was more than I

desired to pay. I regretted to part with him, but he was taken back to

the beach, and I never saw him again.

On another occasion one was brought aboard, and after speaking to him

I gave him an orange; he began to eat it and at the same time caught

hold of the leg of my trousers as if he did not wish me to leave him. I

petted and caressed him for a moment and turned away, but he held on to

me. He waddled about over the deck, holding on to my clothes, and would

not release me. He was afraid of his master and the native boy who had

him in charge. He was a timid creature, but was quite intelligent, and

I felt sorry for him because he seemed to realise his situation.

On the same voyage I saw one in the hands of a German trader. It was a

young male, about one year old. He promptly answered the food sound,

and I called him to come to me; but this he neither answered nor

complied with. He looked at me as if to ask where I had learned his

language. I repeated the sound several times, but elicited no answer.

I have elsewhere called attention to the fact that these apes do not

answer the call when they can see the one who makes it, and they do not

always comply with it. In this respect they behave very much the same

as young children, and it may be remarked that one difficulty in all

apes is to secure fixed attention. This is exactly the same with young

children. Even when they clearly understand, sometimes they betray no

sign of having heard it. At other times they show that they both hear

and understand, but do not comply.

Another specimen that was brought aboard a ship when I was present

was a young male, something less than two years old. He was sullen

and morose. He did not resent my approaches, but he did not encourage

them. I first spoke to him with the food sound, but he gave no heed.

I retired a little distance from him and called him, but he paid no

attention. I then used the sound of warning; he raised his head, and

looked in the direction from which the sound came. I repeated it, and

he looked at me for a moment and turned his head away. I repeated it

again. He looked at me, then looked around as if to see what it meant,

and again resumed his attitude of repose.

On my last voyage to the coast I saw a very good specimen in the Congo.

It was a female, a little more than two years old. She was also of a

dark complexion, but quite intelligent. She had been captured north of

there, and within the limits elsewhere described. At the time I saw her

she was ill and under treatment, but her master, the British consul,

told me that when she was well she was bright and sociable. I made no

attempt to talk with her, except some time after, having left her, I

gave the call sound, which she answered by looking around the corner of

the house. I do not know whether she would have come or not, as she was

tied and could not have done so had she desired to.

I have seen a few other specimens of this ape, and most of them appear

to be of a somewhat higher order than the ordinary chimpanzee, but

there is among them a wide range of intelligence. It would be a risk to

say whether the lowest specimen of kulu is higher or lower than the

highest specimen of the common chimpanzee or not, but taken as a whole

they are much superior. I shall not describe at length the specimens

which have been known in captivity, since most of them have been amply

described by others; but it is not out of place to mention some of them.

If proper conditions were afforded to keep a pair of kulus in training

for some years, it is difficult to say what they might not be taught.

They are not only apt in learning what they are taught, but they are

well-disposed, and can apply their accomplishment to some useful end.

We cannot say to what extent they may be able to apply what they learn

from man, because the necessity of doing so is removed by the attention

given them.
