Pretty soon they came to the palms. These were set closely together, the branches, which came quite to the ground, being so tightly interlaced that even the Glass Cat could scarcely find a place to squeeze through. The path which the Flatheads used was some distance away.

"Here's a job for the Tin Woodman," said the Scarecrow.

So the Tin Woodman, who was always glad to be of use, set to work with his sharp, gleaming axe, which he always carried, and in a surprisingly short time had chopped away enough branches to permit them all to pass easily through the trees.

Now the clear waters of the beautiful lake were before them and by looking closely they could see the outlines of the Great Dome of the sunken island, far from shore and directly in the center of the lake.

Of course every eye was at first fixed upon this dome, where Ozma and Dorothy and the Skeezers were still fast prisoners. But soon their attention was caught by a more brilliant sight, for here was the Diamond Swan swimming just before them, its long neck arched proudly, the amethyst eyes gleaming and all the diamond-sprinkled feathers glistening splendidly under the rays of the sun.
