All I know about it is that a year or so ago I got a letter from Mackenzie, the Scotch missionary, whose station, "The Highlands", is placed at the highest navigable point of the Tana River, in which he said something about it.' 'Have you the letter ?' I asked.
'No, I destroyed it; but I remember that he said that a man had arrived at his station who declared that two months' journey beyond Mt Lekakisera, which no white man has yet visited -- at least, so far as I know -- he found a lake called Laga, and that then he went off to the north-east, a month's journey, over desert and thorn veldt and great mountains, till he came to a country where the people are white and live in stone houses.

Here he was hospitably entertained for a while, till at last the priests of the country set it about that he was a devil, and the people drove him away, and he journeyed for eight months and reached Mackenzie's place, as I heard, dying.

That's all I know; and if you ask me, I believe that it is a lie; but if you want to find out more about it, you had better go up the Tana to Mackenzie's place and ask him for information.' Sir Henry and I looked at each other.

Here was something tangible.
'I think that we will go to Mr Mackenzie's,' I said.
'Well,' answered the Consul, 'that is your best way, but I warn you that you are likely to have a rough journey, for I hear that the Masai are about, and, as you know, they are not pleasant customers.

Your best plan will be to choose a few picked men for personal servants and hunters, and to hire bearers from village to village.
