This is one of those puzzles in which a plurality of solutions is
practically unavoidable. There are two or three positions into which four
frogs may jump so as to form five rows with four in each row, but the
case I have given is the most satisfactory arrangement.

The frogs that have jumped have left their astral bodies behind, in order
to show the reader the positions which they originally occupied. Chang,

explained above in the Frogs and Tumblers solution, makes the shortest
jump of all--a little distance between the two rows; George and
Wilhelmina leap from the ends of the lower row to some distance N. by
N.W. and N. by N.E. respectively; while the frog in the middle of the
lower row, whose name the Professor forgot to state, goes direct S.
