I selected a place in the forest where I found some tracks of the animal along the edge of a dense thicket of _batuna_. Under cover of the foliage I set up two pairs of stakes which were crossed at the tops, and to them was lashed a short pole forming something like a sawbuck. To this was fastened the camera, to which had been attached a trigger made of bamboo splits. One end of a string was fastened to the trigger, and the other end carried under a yoke to a distance of eight feet from the lens. At this point was attached a fresh plantain stalk and a nice bunch of the red fruit of the _batuna_. Upon this point the camera was focussed, the trigger was set, and it was left to await the gorilla. That afternoon I returned to find that something had taken the bait, broken the string, sprung the trigger and snapped the camera. I developed the plate, but could find no image of anything except the leaves in front of it. I repeated the experiment with the same results, but could not understand how anything could steal the bait and yet not be shown in the picture. The third time I did this I was gratified to find the image of a gorilla, and also to discover the cause why the others had not succeeded. The deep shadows of the forest make it difficult to take a photograph without giving it a time exposure, and when the sun is under a cloud or on the wrong side of an object it is quite impossible. The leaves that were shown in the first two plates were only those which were most exposed to the light, and all the lower part of the picture was without detail. In the third trial it could be seen that the sun was shining at the instant of exposure. A part of the body of the gorilla was in the light, but most of it was in the shadow of the leaves above it. The left side of the head and face were quite distinct, also the left shoulder and arm. The hand and bait could not have been distinguished except by their context. The right side of the head, arm, and most of the body were lost. The picture showed that he had taken the bait with his left hand, and that he was in a crouching posture at the moment. While the photograph was very poor as a work of art, it was full of interest as an experiment. Although it did not result in getting a good picture, I do not regard the effort as a failure. It shows at least that such a thing is possible, and by careful efforts often repeated it could be made a means of obtaining some novel pictures. A little ingenuity would widen the scope of this device, and make it possible to photograph birds, elephants, and everything else in the forest. When I return to that place on a like journey, I shall carry the scheme into better effect. CHAPTER XVII OTHER APES
