Mistress Farleigh had told Ruth not to go to the summit of the hill where the troops were camped.

"Thee may walk toward the river, or in the paths at the edge of the wood," Aunt Deborah had said, adding that she wished Hero were at Barren Hill. "Then thee could go wherever thee pleased."

But that day Ruth was content to play with Cecilia in the pleasant garden, hoping until long after sunset that her father might appear.

Neither Aunt Deborah nor Ruth slept well that night, and both were up very early in the morning. After their simple breakfast Aunt Deborah busied herself with bread making, that she might send hot corn bread to the American soldiers.

"And wilt thou not run over to Farmer Withely's and ask Mistress Withely for the loan of a covered basket of good size, Ruth," she suggested, and Ruth willingly obeyed. The Withely farmhouse was at the further side of a broad field, and hidden by a small grove of pine trees. It was a pleasant walk in the early morning, and as Ruth ran along she could see that the American troops were harnessing their horses, and that it was evident some movement was at hand.

"Oh! Perhaps I shall never see Lafayette again, and I did not help him after all," she thought.

And now another and more startling sound came to Ruth's ears. Along the Ridge road she could hear the sound of horses' feet and the rattle of musketry.

"Perhaps it is more American soldiers coming," thought the little girl.

But she felt vaguely troubled, as she went slowly on. She had just entered the little woodland path which led to Farmer Withely's when she saw a glimmer of a red coat in the underbrush.

Ruth stopped, and crouched low behind a small tree. She heard low voices, and in a moment a laughing voice said:

"We have the fine Frenchman just where we want him. He is preparing his men to receive Howe's soldiers on the Ridge road, but he does not dream that General Grant with seven thousand troops is coming up in his rear.

General Howe has invited a dinner party to meet Lafayette to-night in Philadelphia."

"'Tis a fine thing to get the Frenchman," came the low response; "we'd better move farther up the hill now."

For a moment Ruth hesitated, hardly realizing the importance of what she had overheard. Then she turned and ran toward the American encampment, where she could see troops of soldiers already moving forward toward the Ridge road.

"Oh I suppose I do not get there in time to tell him that there is an English army coming behind him," she thought.

Once she stumbled and fell over an unseen root; but at last breathless and tired she found herself facing a number of American soldiers, one of whom called out:

"Run home, child; you are in danger here."

"Lafayette! Lafayette!" she called wildly. "Tell him there are thousands of English soldiers coming up the road behind his army. The road from Swedes Ford," called Ruth.

Almost before Ruth finished speaking one of the soldiers had turned his horse and galloped away to find his commander, and tell him of this unexpected enemy. Ruth turned and hurried home. She had entirely forgotten about her errand to Farmer Withely's.

CHAPTER XXI

AT HOME

Lafayette had received the startling news and acted upon it without a question. He marched his men rapidly toward Matson's Ford, on the lower road, and when the British generals came up to Barren Hill they were astonished to find that they had only each other to fight. They decided not to cross the river, but returned to Philadelphia, much disappointed that the Marquis de Lafayette was not their prisoner.

Lafayette likewise marched back to Valley Forge, where he was received with great joy.

The soldier who had taken Ruth's message found an opportunity to tell Lafayette that the news that had saved his army had been brought by a little girl.

"She came running up the hill calling your name, sir. A little girl with yellow hair and blue eyes," said the soldier.

"Would you know her if you saw her again?" questioned the young Frenchman.

"I should indeed, sir," was the quick reply.

Aunt Deborah had not questioned Ruth when, flushed and tired, she came running back to the house on the morning when the Americans had so easily made their escape, thanks to Ruth's message, from the overwhelming armies of the English. For a number of days Ruth did not venture beyond the garden, and when, a week later, her father opened the gate and called "Ruth!" she ran to meet him, feeling sure that now everything was sure to come right, and that she and her father could soon return to Philadelphia.

But Mr. Pennell was not alone; there was a tall smiling soldier just behind him, and near the gate a graceful figure on horseback that Ruth recognized as Lafayette.

Aunt Deborah came hurrying to welcome Mr. Pennell; the soldier had turned back, and was standing beside the mounted officer, who soon dismounted and came slowly up the path.

"Lieutenant Pennell, I have to thank your little maid for a very great service," he said, as he took Ruth's hand, and smiled down on the little girl; and then he told first of Ruth's warning that his capture was planned by General Howe, and then of her warning of an advancing army against his troops.

"I came this morning that I might thank her for her loyal service to America and to me," he said, bending low to kiss the warm little hand that rested in his own.

It was indeed a wonderful day for Ruth Pennell.

After Lafayette rode away she told the story to her surprised and astonished father, while Aunt Deborah listened as if she could hardly believe her own ears.

Lieutenant Pennell had been given a week's furlough, and was quite sure that it would be possible for him to visit his home in Philadelphia, taking Ruth with him, for the English were leaving the city as rapidly as possible.

Later in the day Aunt Deborah told Ruth's father of his little daughter's visit to General Howe, and Ruth told of Gilbert's play, and of the boys' arrest by the English, of Betty's capture on account of the borrowed coat, and of her escape from the house by the river.

"The children of Philadelphia will indeed remember the year of 1778, and surely my little daughter can never forget it," responded her father.

Ruth was eager to start for home as soon as possible, especially as Aunt Deborah said that she must return in midsummer with her mother for a longer visit. "And thy friend Winifred must come also," she had added.

Winifred and Gilbert had heard the story of Ruth's warning to the American army, for Aunt Deborah had sent a letter to Mrs. Pennell at the first opportunity, and Gilbert had at once declared that he would "make up a play" about it.

"And we will have it the very day Ruth comes home," he said. "I will be Lafayette, and Ruth can be herself."

"And let's ask Betty and all the girls who went to the May party,"

suggested Winifred.

"And Ned, too, and Mother and Mrs. Pennell," agreed Gilbert. "I tell you, it is lucky Ruth went to Barren Hill, and I guess it's lucky you girls went to Southwark that day. You see, it put Ruth on the lookout to warn Lafayette," he added.

Gilbert's second play proved even a greater success than his first. The girls listened admiringly to Winifred's account of Lafayette's thanking Ruth, and when the guests had all gone the two little friends went to their favorite seat in Ruth's garden under the big maple tree. Hero kept very close to his little mistress, as if afraid that she might again suddenly disappear.

"Do you remember that day when we began the chair for Cecilia, Ruthie?"

asked Winifred, "and when you said you wished you could do some great service for Lafayette because he had come to help America?"

Ruth nodded, not quite sure of the exact day, but very sure that she had always wanted to help the young Frenchman, and wondering what Winifred would say next.

"And now you have done him a great service," Winifred continued soberly.

"And Betty and Annette, and all the girls say that you are a real heroine."

"I guess they don't know much about heroines," responded Ruth, but there was a pleased smile about her mouth. Of course any little girl whose hand had been kissed by Lafayette was a heroine, she thought happily.
