“We have waited such a very long time for you to do this,” added Billy.

“If you’ll come up to the nursery we’ll have a drag-hunt for you,” pleaded Drina.  “Everybody is out of the house and we can make as much noise as we please!  Will you?”

“Haven’t you any governesses or nurses or something?” asked Selwyn, finding himself already on the stairway, and still being dragged upward.

“Our governess is away,” said Billy triumphantly, “and our nurses can do nothing with us.”

“I don’t doubt it,” murmured Selwyn; “but where are they?”

“Somebody must have locked them in the schoolroom,” observed Billy carelessly.  “Come on, Uncle Philip; we’ll have a first-class drag-hunt before we unlock the schoolroom and let them out.”

“Anyway, they can brew tea there if they are lonely,” added Drina, ushering Selwyn into the big sunny nursery, where he stood, irresolute, looking about him, aware that he was conniving at open mutiny.  From somewhere on the floor above persistent hammering and muffled appeals satisfied him as to the location and indignation of the schoolroom prisoners.

“You ought to let them out,” he said.  “You’ll surely be punished.”

“We will let them out after we’ve made noise enough,” said Billy calmly.  “We’ll probably be punished anyway, so we may as well make a noise.”

“Yes,” added Drina, “we are going to make all the noise we can while we have the opportunity.  Billy, is everything ready?”

And before Selwyn understood precisely what was happening, he found himself the centre of a circle of madly racing children and dogs.  Round and round him they tore.  Billy yelled for the hurdles and Josephine knocked over some chairs and dragged them across the course of the route; and over them leaped and scrambled children and puppies, splitting the air with that same quality of din which had greeted him upon his entrance to his sister’s house.

When there was no more breath left in the children, and when the dogs lay about, grinning and lolling, Drina approached him, bland and dishevelled.

“That circus,” she explained, “was for your entertainment.  Now will you please do something for ours?”

“Certainly,” said Selwyn, looking about him vaguely; “shall we—­er—­build blocks, or shall I read to you—­er—­out of that big picture-book—­”

“Picture-book!” repeated Billy with scorn; “that’s good enough for nurses to read.  You’re a soldier, you know.  Soldiers have real stories to tell.”

“I see,” he said meekly.  “What am I to tell you about—­our missionaries in Sulu?”

“In the first place,” began Drina, “you are to lie down flat on the floor and creep about and show us how the Moros wriggle through the grass to bolo our sentinels.”

“Why, it’s—­it’s this way,” began Selwyn, leaning back in his rocking-chair and comfortably crossing one knee over the other; “for instance, suppose—­”
