Betty Nelson reached the bank of the river and stopped. She could go no farther for the muddy water stretched itself at her feet. But her boat—the trim little Gem—was moving slowly up the stream under the influence of the mysterious something that was towing it away from the girls.
"Oh!" cried Grace. "What can we do? Betty—Mollie! We must stop it."
"Yes; but how?" asked Mollie. She and the others had followed Betty to the shore.
"We must find another boat, and catch the Gem!" cried Amy. "It isn\'t going very fast."
"If we only could!" murmured Betty, looking helplessly around. But no other boat was in sight. "We must do something," she went on. "We\'ll be marooned if we stay here!"
"But what can be towing our boat?" asked Mollie. She stood on the bank, nervously twining her fingers in and out, weaving them back and[119] forth as she always did when puzzled or alarmed. "Is it the current taking it away, Betty?"
"But it\'s going against the current," Grace pointed out. "Some animal must have become entangled in the anchor or painter, Betty. An alligator, perhaps."
"That\'s it!" cried Mollie. "An alligator is running away with our boat. Oh, Betty!"
"It may be that," admitted the Little Captain, as she gazed after her craft. "I didn\'t think of it, but that\'s probably what it is. I don\'t see the beast above the water, though. Do you, girls?"
There was nothing visible except part of the anchor rope that extended from the ring-bolt in the forward deck, over the stem and slanting down into the water.
"The alligator may be swimming just below the surface," was Mollie\'s opinion. "He may come up pretty soon, and we can throw stones at it. That\'s it, Betty. We must stone the creature and make it let go. Come on!"
Betty laughed. The others looked at Mollie curiously.
"She—she\'s hysterical," murmured Grace.
"I am not!" protested Mollie indignantly.
"But the idea of throwing stones at an alligator!" cried Grace. "Why, its hide will turn a bullet!"[120]
"Oh!" exclaimed Amy blankly. "Then what can we do? We have no bullets!"
"It isn\'t going very fast," observed Mollie as she watched the boat moving slowly up the river. "We can run along the bank after it, and maybe the beast will let go, or run ashore with the Gem. Then we could get it."
"Who—the boat or the alligator?" asked Betty, who seemed to be in better spirits now, even in the face of trouble.
"The boat, of course."
"Then speak of the Gem as \'her\' and the alligator as \'it,\'" Betty directed. "But I believe Mollie\'s plan is the only one we can adopt. We must follow along the bank. Only I hope, if the alligator does let go, it won\'t be in the middle of the river, for then our boat would float down, and it might lodge on the other shore. Then we would be as badly off as we are now. Oh, what a predicament! We seem to be getting into nothing but trouble of late."
"Never mind," consoled Amy. "Maybe this will be the last."
"It\'s a comfort to think so, anyhow," agreed Grace. "I wonder why an alligator ran off with our boat?"
"A mere accident," was Betty\'s opinion. "Probably the creature was swimming along[121] shore, and became entangled in our anchor rope. It may be as much frightened as we are distressed. But come on, if we\'re going to try to get the boat."
Stumbling over the uneven way, the girls raced along the river bank. Sometimes the boat appeared to be coming close in shore, and again it would veer out.
"I\'ve just thought of something!" exclaimed Amy as they came up nearly opposite the boat, for it was being towed more slowly now, as though the creature having it in charge found it harder work.
"Then do, for goodness sake, tell us what it is," demanded Mollie. "I\'m about played out."
"If we threw stones on the other side of the alligator—I mean across, between him and the other shore—it might scare him over this way."
"Oh!" screamed Grace. "Don\'t you dare scare him over here!"
"I didn\'t mean right here," went on Amy. "I only meant farther in toward this shore. Then he might run aground and we could wade out and get the boat."<............
