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.
