When two miles or more had probably been passed over, Hugh began to pay strict attention to the landmarks as they opened up. The stars overhead gave abundant light on the beach for them to see fairly well where they were going. On the right the soft murmur of the little wavelets rolling up the pebbly strand, so new a sound to these lads from the interior, was like sweet music in their ears. On the left lay sand dunes that were like great Indian mounds, and which might conceal any number of spies should the defenders of the coast fort have thought it worth while to send them out in order to keep watch for the coming of the enemy; Hugh hoped this would not prove to be the case.
Several times the boys had little scares. An owl that had been prowling in search of food close to the water’s edge suddenly flew off with a rush, and went winnowing its way to the nearby woods. Then a little later on some small animal scurried away, none of them being able to identify it positively in the uncertain light, although Hugh guessed it might have been a fox that had wandered down in hopes of picking up something worth eating.
These were small matters, it is true, but with the nerves of the scouts on edge, as it were, they served to keep them thrilled with anticipations of possible discovery. Hugh redoubled his caution when the second mile had been passed over. He knew that they were now getting near the shore front. If by the use of marine glasses the commander in charge had been able to pick up the distant Vixen before the shades of night had enveloped her advance, he would of course have his men use double vigilance in order that the fortunes of war might not be decided against them by the Naval Reserve capturing his post.
Here was where the knowledge obtained from the chart on board came in handy for Hugh. He was able at any time to know just where they had arrived, and to understand the situation ahead.
The scouts were now advancing very slowly, bringing into use many of the little tricks they had learned when playing the Indian game in the woods. It was easy work making their way along the open beach. Hugh had now taken them away from the water so as to secure more or less protection from the trees further back. Here they felt more at home, and the forward movement was kept up steadily, minute after minute.
Then finally the scout master discovered that just ahead of them there lay a peculiar formation of rocks. It ran all the way down to the water, and further out, until lost to sight under the sea. This line of ragged rocks had all the characteristics of a reef, only that it did not agree with the conformation of the coast as most reefs do.
Here was the place that had been selected for the clever work of the signal corps on the morrow. The scouts were to hide amidst these rocks until dawn allowed the leaders to spy upon the fort with the field glasses they had brought along for the purpose.
An hour or so before daybreak three of their number were to start back along the beach to take up positions which had been pointed out by the scout master while they were making their advance. These were to remain constantly on the watch for any signals which might come in the shape of the semaphore alphabet, wigwag work, or through the use of a piece of broken mirror, with which each fellow had been armed before leaving the ship, and which, in case of the sun shining, was to be used as a means of sending messages along the line.
Should Hugh deem it safe to wave the white flag with its red square in the center, he would expect that method to be put in practice, but as this would mean more or less exposure on the beach, possibly it could not be used.
It was with more or less thankfulness that he led his scouts into the clump of rocks where they meant to make themselves as comfortable as the conditions would allow. Here they could move around even after day came, so long as they kept themselves from being seen by those in the fort. Doubtless, the garrison would have numerous duties to perform, and beyond keeping a fairly smart lookout for signs of an advancing suspicious vessel, it would not go to any further trouble.
