I once, and only once, had an opportunity of seeing elephants that were either migrating, or had just arrived from a migration. This was between 3 degrees and 4 degrees N. latitude in Africa, between Obbo and Farajok. We were marching through an uninhabited country for about 30 miles, and in the midst of beautiful park-like scenery we came upon the magnificent sight of vast herds of elephants. These were scattered about the country in parties varying in numbers from ten to a hundred, while single bulls dotted the landscape with their majestic forms in all directions. In some places there were herds of twenty or thirty entirely composed of large tuskers; in other spots were parties of females with young ones interspersed, of varying growths, and this grand display of elephantine life continued for at least 2 miles in length as we rode parallel with the groups at about a quarter of a mile distant. It would have been impossible to guess the number, as there was no regularity in their arrangement, neither could I form any idea of the breadth of the area that was occupied. I have often looked back upon that extraordinary scene, and it occurred to me forcibly in after years, when I had 3200 elephants' tusks in one station of Central Africa, which must have represented 1600 animals slain for their fatal ivory. The day must arrive when ivory will be a production of the past, as it is impossible that the enormous demand can be supplied. I have already explained that the African savage never tames a wild animal, neither does he exhibit any sympathy or pity, his desire being, like the gunner of the nineteenth century, to exterminate. It may be readily imagined that wholesale destruction is the result whenever some favourable opportunity delivers a large herd of elephants into the native hands. There are various methods employed for trapping, or otherwise destroying. Pitfalls are the most common, as they are simple, and generally fatal. Elephants are thirsty creatures, and when in large herds they make considerable roads in their passage towards a river. They are nearly always to be found upon the same track when nightly approaching the usual spot for drinking or for a bath. It is therefore a simple affair to intercept their route by a series of deep pitfalls dug exactly in the line of their advance. These holes vary in shape; the circular are, I believe, the most effective, as the elephant falls head downwards, but I have seen them made of different shapes and proportions according to the individual opinions of the trappers.
