"We'll take a wheelbarrow, and bring heaps up from the beach." The Sand Club worked for days getting their palace in order.

The two big boys wheeled many loads of sand up from the beach, and Marjorie and the two other boys arranged it in shape.
Dick was clever at building, and he planned a number of fine effects.

Of course, their palace had no roof or walls, but the apartments were partitioned off with low walls of sand, and there were sand sofas and chairs, and a gorgeous throne.
The throne was a heap of sand, surmounted by a legless armchair, found in the Craigs' attic, and at court meetings draped with pink cheesecloth and garlands of flowers.

The whole palace was really a "secret haunt," for a slight rise of ground screened it from view on two sides and trees shaded the other side.
The parents of both families were pleased with the whole scheme, for it kept the children occupied, and they could always be found at a moment's notice.
Sand tables were built, and on them were bits of old dishes and broken vases, all of which were desirable because they could stay out in the rain and not be harmed.

Moreover, they were handy in case of a feast.
