In all dealings with natives the European must remember that they have no idea of the value we place upon time; there is no use in saying, “Let us come to the point at once.” It is far better, indeed it is absolutely necessary, to delay judiciously, as there is always an implied contest between visitors; and the man who is in a hurry to speak loses dignity. Do not disturb your informant’s train of thought, but try to accommodate your own to it. Let him tell as minutely and tediously as he pleases how he has travelled; how long he walked with the rising sun on his right or left; how much he turned either way; where he halted for rest or refreshment; whether he crossed rivers on foot or in canoes; induce him, if possible, to trace a map upon the ground, in doing which he will most probably begin by making the direction of all his lines coincide with the actual bearing of the country; for natives, though they may be brought to comprehend a map when its north point coincides with the real north, cannot believe that it is also right when it is placed in any other position. We have frequently tested Hottentots with regard to the direction of places a thousand miles distant, and have found them point as correctly as we could take the bearing with a pocket compass.
Sometimes it will be found that the same individual will give a river a dozen different names; and this is often because, in speaking of the different parts of it, he gives to each the name of the chief who has his village there, and who “drinks water” at the place which is called after him; therefore, endeavour to ascertain whether the river has a real name, and do not apply to it the first and, perhaps, the most inappropriate name that is given.
Europeans who have settled in the colonies, and have become traders or hunters, frequently push very far into the interior, and such men have generally very clear ideas of direction and locality, but are often very modest and diffident when asked to furnish information to be laid down on paper. In 1849, while staying at the Vaal River, we persuaded our friend Macabe, with some difficulty, to give us the length in “hours” and the direction of the various stages of his journey on the river Limpopo. These, with the rivers, mountains, villages, and other features of the country, we laid down, on a scale of one inch to a mile, on several sheets of cartridge paper, and tested the correctness of our work by laying it on the floor, with its north coinciding with the real north, and requesting our Dutch visitors to stand as if they were about commencing the same journey, and indicate how much they turned to the right or left as they proceeded.
The following facts relating to time should be impressed on the memory of every traveller:—The earth is divided in its circumference into 360°; the day is divided into twenty-four hours. It therefore follows that 15° of longitude will represent one hour of time; consequently, as you travel towards the east, when you have journeyed over 15°, you will have gained one hour on the sun, which will rise just one hour earlier than it did at the starting point.
If natives accompany you on a journey, ask them to point in the direction of places at different times, and particularly to tell you when you are exactly abreast of them, as well as before, and after you have passed, and thus, by a kind of rough triangulation, you will gain their approximate position.
If cattle stray to great distances, ask the men who go after them the reason of their having taken any particular direction, and you will probably gain some information respecting the form of valleys or mountains, and perhaps of watering places.
In North Australia we were led by the tracks of horses, which had been lost about a fortnight, to a considerable stream.
