But in the very midst of one of his wildest whirls, he heard a sound that brought him up short, as still as a stone. It was the sound of a heavy thump, and it came from the direction of the Old Briar-patch. Tommy didn’t need to be told that it was a signal, a signal from Peter Rabbit to all other rabbits within hearing distance. He didn’t know just the meaning of that signal, and, because he didn’t, he just sat still.
Now it happens that that was exactly what that signal meant—to sit tight and not move. Peter had seen something that to him looked very suspicious. So on general principles he had signaled, and then had himself sat perfectly still until he should discover if there was any real danger.
Tommy didn’t know this, but being a rabbit now, he felt as a rabbit feels, and, from the second he heard that thump, he was as frightened as he had been happy a minute before. And being frightened, yet not knowing of what he was afraid, he sat absolutely still, listening with all his might, and looking this way and that, as best he could, without moving his head. And all the time, he worked his nose up and down, up and down, as all rabbits do, and tested the air for strange smells.
Presently Tommy heard behind him a sound that filled him with terrible fear. It was a loud sniff, sniff. Rolling his eyes back so that he could look behind without turning his head, he saw a dog sniffing and snuffing in the grass. Now that dog wasn’t very big as dogs go, but he was so much bigger than even the largest rabbit that to Tommy he looked like a giant. The terrible fear that filled him clutched at Tommy’s heart until it seemed as if it would stop beating.
What should he do, sit still or run? Somehow he was afraid to do either. Just then the matter was settled for him. “Thump, thump, thump!” the signal came along the ground from the Old Briar-patch, and almost any one would have known just by the short sharp sound that those thumps meant “Run!” At just the same instant, the dog caught the scent of Tommy full and strong. With a roar of his great voice he sprang forward, his nose in Tommy’s tracks.
Tommy waited no longer. With a great bound he leaped forward in the direction of the Old Briar-patch. How he did run! A dozen bounds brought him to the Old Briar-patch, and there just before him was a tiny path under the brambles. He didn’t stop to question how it came there or who had made it. He dodged in and scurried along it to the very middle of the Old Briar-patch. Then he stopped to listen and look.
The dog had just reached the edge of the briars. He knew where Tommy had gone. Of course he knew. His nose told him that. He thrust his head in at the entrance to the little path and tried to crawl in. But the sly old brambles tore his long tender ears, and he yelped with pain now instead of with the excitement of the chase. Then he backed out, whining and yelping. He ran around the edge of the Old Briar-patch looking for some place where he could get in more comfortably. But there was no place, and after a while he gave up and went off.
Tommy sat right where he was until he was quite sure that the dog had gone. When he was quite sure, he started to explore the dear Old Briar-patch, for he was very curious to see what it was like in there. He found little paths leading in all directions. Some of them led right through the very thickest tangles of ugly looking brambles, and Tommy found that he could run along these with never a fear of a single scratch. And as he hopped along, he knew that here he was safe, absolutely safe from most of his enemies, for no one bigger than he could possibly get through those briars without being terribly scratched.
So it was with a very comfortable feeling that Tommy peered out through the brambles and watched that annoying dog trot off in disgust. He felt that never, so long as he was within running distance of the dear Old Briar-patch, would he be afraid of a dog.
Right into the midst of his pleasant thoughts broke a rude “Thump, thump, thump!” It wasn’t a danger-signal this time. That is, it didn’t mean “Run for your life.” Tommy was very sure of that. And yet it might be a kind of danger-signal, too. It all depended on what Tommy decided to do.
