Seven on the day.
CONGO RIVER--March 1, 1907.
DEAR MOTHER: I have been up the Congo as far as the Kasai river, and up that to a place called Dima.

There I found myself in a sort of cul de sac.

I found that the rubber plantations I had come to see, were nine days journey distant.

In this land where time and distance are so differently regarded than with us, a man tells you to go to Dima to see rubber.

He means after getting to Dima, you must catch a steamer that leaves every two weeks and travel for five days.
