Giving the donkey the first move, how soon can you place the man in such a position that the ass is cornered and cannot escape being bridled?
8. Like to Like
Fig. 6.—“Like to like.”
Four black and four white counters are placed alternately in a row of ten divisions, shown in [Fig. 6]. By moving two at a time, how can you arrange all the blacks and all the whites together in four moves?
9. The Broken Chain
A lady once took to a jeweler a gold chain, broken into five pieces of three links each ([Fig. 7]). She asked him to repair the chain, agreeing to pay 25 cents for each link that he had to break and weld in order to restore the chain to its original length.
The following day she sent her maid for the chain with 75 cents. If you had been the jeweler, how would you have mended this chain of five pieces by breaking only three links?
