twelve
o'clock
I 'm quite satisfied now , William , we shall do very well , and all we have now to think of is moving away from the other side of the island as fast as possible . '' `` Shall we go back to-day ? '' `` Yes , I think so , for we shall only be idle here . It is not twelve o'clock , I should think , and we shall have plenty of time . I think we had better start at once ; we will leave the spade and axe here , for it is no use taking them back again . The musket I will take along . But first let us go back and look at the spring , and see how the water flows . ''
