“I’d ought to go, to be there in time for school on Monday,” the lad agreed.
“Couldn’t you make it if you took the early morning train?” Nann inquired.
“May be so,” Dick replied, “but we can decide that later. The big thing just now is, how’re we going to get out of this creek?”
“Why – ” The girls looked helplessly from one boy to the other. “Is there any problem about it? Can’t you just push out the way you pushed in?”
Dick’s expression betrayed his perplexity. “Hmm! I’m not at all sure, with the tide going out as fast as it is now.”
“Gracious!” Dories looked up in alarm. “We won’t have to stay in this dreadful marsh until the tide turns, will we?” Then appealingly, “Oh, Dick, please do hurry and try to get us out of here. Aunt Jane will be terribly worried if we don’t get home before dark.”
The boy addressed had already leaped to the stern of the boat and was pushing on the one oar with all his strength. Gib snatched the other oar and tried to help, but still they did not move. Then Nann had an inspiration. “Dori,” she said, “you catch hold of the reeds on that side and I will on this and let’s pull, too. Now, one, two, three! All together!”
Their combined efforts proved successful. The punt floated, but it was quite evident that they would have to travel fast to keep from again being grounded, so they all four continued to push and pull, and it was with a sigh of relief that they at last reached deeper water as the channel widened into the sea.
“Well, that certainly was a narrow escape,” Nann exclaimed as the punt slipped out of the narrow channel of the marsh into the quiet waters of the cove.
“Now we know why the pilot of the airplane left. He probably visits the old ruin only at high tide, when he is sure that there is water enough in the creek,” Dick announced.
Dories seemed greatly relieved that the expedition had returned to the open, and, as it was sheltered in the cove, the boys soon rowed across to the point of rocks. “If Gib could leave the punt here where the water is so sheltered and quiet, your mother, Dick, would not object even if you went out when the tide is high, would she?” Nann inquired.
“No, indeed,” the boy replied. “Mother merely had reference to the open sea. A punt would have little chance out there if it were caught between the surf and the rocks, but here it is always calm.”
While they had been talking, Gib had been busy letting his home-made anchor overboard. It was a heavy piece of iron tied to a rope, which in turn was fastened to the bow.
“Hold on there, Cap’n!” Dick merrily called. “Let the passengers ashore before you anchor.” Gib grinned as he drew the heavy piece of iron back into the punt. Then Dick rowed close to the rocks and assisted the girls out.
“What shall we do now?” he turned to ask when he saw that Gib had pushed off again. He dropped the anchor a little more than a boat length from the point, pulled off his shoes and stockings and waded to the rocks. After putting them on again he joined the others, who had started to climb.
When they reached the wide, flat “tiptop” rock Dories sank down, exclaiming, “Honestly, I never was so hungry before in all my life.” Then, laughingly, she added, “Nann Sibbett, here we have been carrying that box of lunch all this time and forgot to eat it. The boys must be starved.”
“Whoopla!” Dick shouted. “Starved doesn’t half express my famished condition. Does it yours, Gib?”
The red-headed boy beamed. “I’m powerful hungry all right,” he acknowledged, “but I’m sort o’ used to that.” However, he sat down when he was invited to do so and ate the good sandwiches given him with as much relish as the others.
Half an hour later they were again on the sand walking toward the row of cottages. Nann glanced at the upper window of the Burton cabin, and Dick, noticing, glanced in the same direction. Then, smiling at the girl, he said, “I guess, after all, there has been no one in the cottage. The blind is still closed just as I left it yesterday.”
“We’ll look again tonight,” Nann said, adding, “We’ll each have to carry a lantern.”
“What are you two planning?” Dories asked suspiciously.
“Can’t you guess the meaning that underlies our present conversation?” Nann smilingly inquired.
“Goodness, I’m almost afraid that I can,” was her friend’s queer confession. “I do believe you are plotting a visit to the old ruin at the turn of the tide, and that will not be until midnight, Gib said.”
“It’s something like that,” Dick agreed.
“Well, you can count me out.” Dories shuddered as she spoke.
Nann laughed. “I know just exactly what will happen (this teasingly) when you hear me tiptoeing down the back stairs. You’ll dart after me; for you know you’re afraid to stay alone in our loft at night.”
“You are wrong there,” Dories contended. “Now that I know about the ghost, I won’t be afraid to stay alone, and I would be terribly afraid to go to the ruin at midnight, even with three companions.”
“Speaking of lanterns,” Dick put in, “if it’s foggy we won’t be able to go at all. That would be running unnecessary risks, but if it is clear, there ought to be a full moon shining along about midnight, and that will make all the light we will need.” Then he hastened to add, “But we’ll take lanterns, for we might need them inside the old ruin, and what is more, I’ll take my flashlight.”
The boys had left the white horse tied to the cottage nearest the road. When they had mounted, Spindly started off as suddenly as hours before it had stopped.
“Good-bye,” Dick waved his cap to the girls, “we’ll whistle when we get to the beach.”
“Just look at Spindly gallop,” Dories said. “The poor thing is eager to get to its dinner, I suppose.” Arm in arm they turned toward their home-cabin.
“My, such exciting things are happening!” Nann exclaimed joyfully. “I wouldn’t have missed this month by the sea for anything.”
Dories shuddered. “I’ll have to confess that I’m not very keen about visiting the old ruin at – ” She interrupted herself to cry out excitedly, “Nann, do look over toward the island. We forgot all about that sea plane. There it is just taking to the air. What do you suppose it has been doing out on that desolate island all this time?”
Nann shook her head, then shaded her eyes to watch the airplane as it soared high, again headed for Boston.
“Little do you guess, Mr. Pilot,” she called to him, “that tonight we are to discover the secret of your visits to the old ruin.”
“Maybe!” Dories put in laconically.
CHAPTER XXII
THE OLD RUIN AT MIDNIGHT
Never had two girls been more interested and excited than were Dories and Nann as midnight neared. Of course they neither of them slept a wink nor had they undressed. Nann had truly prophesied. Dories declared that when she came to think of it, nothing could induce her to stay alone in that loft room at midnight, and that if she were to meet a ghost or any other mysterious person, she would rather meet him in company of Nann, Dick and Gib.
Every hour after they retired, they crept from bed to gaze out of the small window which overlooked the ocean. At first the fog was so dense that they could see but dimly the white line of rushing surf out by the point of rocks.
“Well, we might as well give up the plan,” Dories announced as it neared eleven and the sky was still obscured.
But Nann replied that when the moon was full it often succeeded in dispelling the fog by some magic it seemed to possess, and that she didn’t intend to go to sleep until she was sure that the boys weren’t coming. She declared that she wouldn’t miss the adventure for anything.
Dories fell asleep, however, and, for that matter, so, too, did Nann, and since they were both very weary from the unusual excitement and late hours, they would not have awakened until morning had it not been for a low whistle at the back of the cabin.
Instantly Nann sprang up. “That must be Gib,” she whispered. Then added, jubilantly: “It’s as bright as day. The moon is shining now in all its splendor.”
In five seconds the two girls had crept down the outer stairway, and as they tiptoed across the back porch, two dark forms emerged from the shadows and approached them.
“Hist!” Gib whispered melodramatically, bent on making the adventure as mysterious as possible. “You gals track along arter us fellows, and don’t make any noise.”
Then without further parley, Gib darted into the shadow of the woodshed, and from there crept stealthily along back of the seven boarded-up cabins.
“What’s the idea of stealing along like this?” Nann inquired when the wide sandy spaces were reached.
“We thought we’d keep hidden as much as possible,” Dick told her. “For if that airplane pilot is anywhere around, we don’t want him to get wise to us.”
“But, of course, he isn’t around,” Dories said. “How could he be? An airplane can’t fly over our beach without being heard. It would waken us from the deepest sleep, I am sure.”
