Not a Nit!!!
The original statement of the problem:
the conundrum was to determine which one of these interesting savages was which.
Note that there is nothing in this statement to eliminate the possibility that there are more than two Indians here!
It is therefore, I submit, quite possible that there are so many Indians that they are not all known to each other. Therefore, there is the possiblity that they are all known to a liar who could then be lying by answering the question, "Are your feet the same color as..." with the answer, "I don't know" and a truth teller could answer the same question with the same answer if he didn't know everybody.
What's all this in aid of? TEd's answer, which covers the possibility that both tribes are not represented, which, by the way, I do not see as excluded from the possibilities in the original statement of the problem, could not possibly be wrong and he deserves more credit than he was given.
