Let us now see what degrees of kindred are prohibited by these laws.
Let us take the case of a man of class A. He can only marry a woman of
class B, whose parents must therefore have belonged to classes C and D her
mother being a C and her father a D.
Therefore his wife's mother and father belong to classes with which he
may not intermarry.
Therefore a man may not marry -
1. His mother-in-law.
2. The sister of his wife's mother.
3. The sister of his wife's father.
4. Nor the sister of any one of the three.
5. Nor can he marry his sister.
But he may marry -
His wife's sisters (sisters by blood or tribal class).
And as far as I can see, no law prevents a man from marrying his
grandmother should he so desire.
CHAPTER II
STURT CREEK AND "GREGORY'S SALT SEA"
The Sturt Creek presents many points of interest. It rises in the
Northern Territory, runs for nearly three hundred miles in a
South-Westerly direction, and comes to an end in a large salt-lake, across
the border, in the desert. It runs throughout its entire length once in
every three or four years, though each yearly rainy season floods it in
certain parts.
