They immediately sat down to arrange their signals. Montgomery was of course trained in this work, and easily fixed up a simple scheme by which certain orders could be given by either flags, or lights, or rockets. There was not need for much complication; it was understood that when the _Wilhelmina_ should be sighted she should be boarded at once, wherever or however she might be. We were, one and all of us, prepared to set at defiance every law--international, maritime, national or local. Under the circumstances we felt that, given we could once get on track with our enemy, we held a great power in our hands. Before long, MacRae was off to Peterhead to join his yacht, which would at once start on a sort of sentry-go up and down the coast. The rest of us set about arranging to spread ourselves along the shore between Cruden and Peterhead. We did not arrange watches, for time was now precious to all, on both sides of the encounter. If an attempt was to be made to take off the treasure, it would in all probability be made before morning; every hour that passed multiplied the difficulties and dangers of the blackmailers. The weather was becoming misty, which was a source of inconvenience to us all. Thick patches of white fog began to drift in from the north east, and there was ominous promise in the rising wind of there being danger on sea and shore before many hours had passed. We each took provision with us for the night, and a sufficiency of rockets and white and red lights for our signalling work, in case there might be need of such.
