Four Outlines are lettered at D, D, D, D.)]

Fig. 397 is made up of six pieces and is the simplest of the group to
solve. Although containing only five pieces, Fig. 398 will be found to
give more trouble.

Fig. 399, with ten pieces, is undoubtedly the most trying puzzle, and
will be found as baffling as many jig-saw pictures. Fig. 400, again,
presents only moderate difficulties.

If the reader prefers, he may cut the squares to the size illustrated
instead of enlarging them.
