He approved of Philip's idea, and he and Perrin were soon busy making plans, calculating strains and selecting materials.

Then Philip made a speech to the islanders and explained his idea. There was a great deal of cheering and shouting, and every one agreed that an ark on the topmost tower would meet a long-felt want, and that when once that ark was there, fear would for ever be a stranger to every gentle island heart.

And now the great work of building began. Mr. Perrin kindly consented to act as foreman and set to work a whole army of workmen—the M.A.'s of course. And soon the sound of saw and hammer mingled with the plash of waves and cries of sea-birds, and gangs of stalwart M.A.'s in their seaweed tunics bent themselves to the task of shaping great timbers and hoisting them to the top of the highest tower, where other gangs, under Mr. Noah's own eye, reared a scaffolding to support the ark while the building went on.

The children were not allowed to help, but they loved looking on, and almost felt that, if they looked on earnestly enough, they must, in some strange mysterious way, be actually helping. You know the feeling, I daresay.

The Hippogriff, who was stabled in the castle, flew up to wherever he was wanted, to assist in the hauling. Mr. Noah only had to whisper the magic word in his ear and up he flew. But what that magic word was the children did not know, though they asked often enough.

And now at last the ark was finished, the scaffolding was removed, and there was the great Noah's ark, firmly planted on the topmost tower. It was a perfect example of the ark-builder's craft. Its boat part was painted a dull red, its sides and ends were blue with black windows, and its roof was bright scarlet, painted in lines to imitate tiles. No least detail was neglected. Even to the white bird painted on the roof, which you must have noticed in your own Noah's ark.

They loved looking on.

A great festival was held, speeches were made, and every one who had lent a hand in the building, even the humblest M.A., was crowned with a wreath of fresh pink and green seaweed. Songs were sung, and the laureate of the Sea-Dwellers, a young M.A. with pale blue eyes and no chin, recited an ode beginning—

Now that we have our Noble Ark
No more we tremble in the dark
When the great seas and the winds cry out,
For we are safe without a doubt.

At undue risings of the tide
Within our Ark we'll safely hide,
And bless the names of those who thus
Have built a painted Ark for us.
