"We'll try as well as we know how, and the first thing we will do is to give that old secretary a good rummage from top to bottom. I've done it once, but it is just possible that the bills may have slipped out of sight. Come, now, I can't rest till I've done all I can to comfort you and convince Thorny." Miss Celia rose as she spoke, and led the way to the dressing-room, which had no outlet except through her chamber. Still holding his hat, Ben followed with a troubled face, and Thorny brought up the rear, doggedly determined to keep his eye on "the little scamp" till the matter was satisfactorily cleared up. Miss Celia had made her proposal more to soothe the feelings of one boy and to employ the superfluous energies of the other, than in the expectation of throwing any light upon the mystery; for she was sadly puzzled by Ben's manner, and much regretted that she had let her brother meddle in the matter.

"There," she said, unlocking the door with the key Thorny reluctantly gave up to her, "this is the room and that is the drawer on the right. The lower ones have seldom been opened since we came, and hold only some of papa's old books. Those upper ones you may turn out and investigate as much as you— Bless me! here's something in your trap," Thorny and Miss Celia gave a little skip as she nearly trod on a long, gray tall, which hung out of the bole now filled by a plump mouse.

But her brother was intent on more serious things, and merely pushed the trap aside as he pulled out the drawer with an excited gesture, which sent it and all its contents clattering to the floor.

"Confound the old thing! It always stuck so I had to give a jerk. Now, there it is, topsy-turvy," and Thorny looked Much disgusted at his own awkwardness.

"No harm done; I left nothing of value in it. Look back there, Ben, and see if there is room for a paper to get worked over the top of the drawer. I felt quite a crack, but I don't believe it is possible for things to slip out; the place was never full enough to overflow in any way."

Miss Celia spoke to Ben, who was kneeling down to pick up the scattered papers, among which were two marked dollar bills,—Thorny's bait for the thief. Ben looked into the dusty recess, and then put in his hand, saying carelessly,—

"There's nothing but a bit of red stuff."

"My old pen-wiper—Why, what's the matter?" asked Miss Celia, as Ben dropped the handful of what looked like rubbish.

"Something warm and wiggly inside of it," answered Ben, stooping to examine the contents of the little scarlet bundle. "Baby mice! Ain't they funny? Look just like mites of young pigs. We'll have to kill 'em if you've caught their mamma," he said, forgetting his own trials in boyish curiosity about his "find."

Miss Celia stooped also, and gently poked the red cradle with her finger; for the tiny mice were nestling deeper into the fluff with small squeals of alarm. Suddenly she cried out: "Boys, boys, I've found the thief! Look here; pull out these bits and see if they won't make up my lost bills."
