No. CXXVI.—WALNUTS AND COBS
A good after dinner trick
Place four walnuts and four cobnuts in a row, as indicated on the diagram.
Now, moving always two that stand together, transfer them to some other positions along the line, and in four such moves leave them so that the large and small nuts range alternately. It may, of course, be done with large and small coins, or with other things that are at hand.
