A corner of one of the overturned bookcase sections struck Russ Bunker's head with considerable force—actually cutting the skin and bringing blood. Big as he was, the oldest Bunker yelled loudly.

Then, of course, everybody yelled. Quite a panic followed. When Aunt Jo and Mother Bunker came running to the front room where all this had taken place the Eskimo igloo looked very much like a pile of boxes with a young earthquake at work beneath it!

"For the good land's sake!" gasped Aunt Jo, who usually was very particular about her speech, but who on this occasion was startled into an exclamation. "What is happening?"

"Get off my head, Vi!" wailed Laddie, from somewhere under the tottering pile. "It's not to sit on."

"Oh! Oh!" cried Rose. "Russ is all bloody! Oh, dear!"

"I'm not cold any more," cried Mun Bun. "Let me out! I'll be good!"

But Russ Bunker was neither crying nor struggling. He was a good deal of a man, for a nine-and-a-half-year-old boy. Being the oldest of the six little Bunkers there were certain duties which fell to his lot, and he understood that one of them was to keep cool when anything happened to excite or frighten his brothers and sisters.

The whack he had got on the head, and even the trickle of blood down his face, did not cause Russ to lose his head. No, indeed. He, and the other little Bunkers, had been in innumerable scrapes before, and the wreck of the Eskimo igloo was nothing provided Aunt Jo did not make a lot out of it. It just crossed Russ' mind that he ought to have asked his aunt before he used the sectional bookcases for building-blocks.

Naturally of an inventive turn of mind, Russ was constantly building new things—make-believe houses, engines, automobiles, steamboats, and the like—usually with a merry whistle on his lips, too. He was a cheerful boy and almost always considered the safety and pleasure of his brothers and sisters first.

In companionship with Rose, who was a year younger, the boy cared for the other four little Bunkers so successfully that Mother Bunker and Daddy Bunker were seldom troubled in their minds regarding any of the children. Rose was a particularly helpful little girl, and assisted Mother Bunker a good deal. She was a real little housewife.

Vi and Laddie, the twins, were both very active children—active with their tongues as well as their bodies. Violet's inquisitiveness knew no bounds. She wanted to know about every little thing that happened about her. Daddy Bunker said he was sure she must ask questions in her sleep. Laddie was an inveterate riddle-asker. He learned every riddle he heard; and he tried to make up riddles about everything that happened. Sometimes he was successful, and sometimes he was not. But he always tried again, having a persevering temperament.The smallest Bunkers—Margy, whose real name was Margaret, and Mun Bun, whose real name was Monroe Ford—were quite as anxious to get out from under the heap of boxes as the others. Mother Bunker and Aunt Jo ran to their assistance, and soon the six were on their feet to be hugged and scolded a little by both their mother and aunt.

"But they do get into such mischief all the time," sighed Mother Bunker. "I shall be glad when Daddy gets back and decides what to do for the winter. I don't know whether we shall go right back to Pineville or not."

For it was in Pineville, Pennsylvania, that we first met the six little Bunkers and in the first volume of this series went with them on a nice vacation to Mother Bunker's mother. The book telling of this is called "Six Little Bunkers at Grandma Bell's."

After that lovely visit in Maine the six little Bunkers had gone to stay for a time with each of the following very delightful relatives and friends: To Aunt Jo's in Boston, where they were now for a second visit over the Thanksgiving holidays; to Cousin Tom's; to Grandpa Ford's; to Uncle Fred's; to Captain Ben's; and last of all to Cowboy Jack's.

In that last book, "Six Little Bunkers at Cowboy Jack's," they had enjoyed themselves so much that they were always talking about it. And now, as Vi managed to crawl out from under the wreck of the Eskimo igloo, she announced:

"That iggilyoo isn't half as nice to live in as Chief Black Bear's wigwam was at Cowboy Jack's. You 'member that wigwam, Russ?"

"I remember it, all right," said Russ, rather ruefully touching the cut above his temple and bringing away his finger again to look at the blood upon it. "Say, is it going to keep right on bleeding, Mother?"

"Not for long," declared Mother Bunker. "But I think you were rightly punished, Russ. Suppose the corner of the section had cut Mun Bun's head?"

"I should have been awful sorry," admitted Russ. "I guess I didn't think much, Mother. I was only trying to amuse 'em 'cause they were cold."

"It is cold in here, Amy. Don't scold the boy. See! The storm is getting worse. I don't know what we shall do about the fire. Parker and Annie don't seem to know what to do about the heater and I'm sure I don't. Oh, dear!"

"B-r-rrr!" shivered Mother Bunker. "I am not fond of your New England winters, Jo. I hope we shall go South——"

"Oh, Mother!" cried Rose excitedly. "Shall we really go down South with Daddy? Won't that be glorious?"

"I guess it's warm down there," said Laddie. "Or maybe the steampipes hum."

"Do the steampipes hum down South?" asked Violet.

While the four older children were exceedingly interested in this new proposal for excitement and adventure, Margy and Mun Bun had returned to the great window that overlooked the street and the front steps. They flattened their noses against the cold pane and stared down into the driving snow. Within this short time, since the storm had begun, everything was white and the few people passing in the street were like snowmen, for the white flakes stuck to their coats and other wraps.

"Oh, see that man!" Margy cried to Mun Bun. "He almost fell down."

"He's not a man," said her little brother with confidence. "He's a boy."

"Oh! He's a black boy—a colored boy. That's right, so he is."

The figure in the snow stumbled along the sidewalk, clinging to the iron railings. When he reached the steps of Aunt Jo's house he slipped down upon the second step and seemed unable to get up again. His body sagged against the iron railing post, and soon the snow began to heap on him and about him.

"Oh!" gasped Margy. "He is a reg'lar snowman."

"He's a black snowman," said Mun Bun. "It must be freezing cold out there, Margy."

"Of course it is. He'll turn into a nicicle if he stays there on the steps," declared the little girl, with some anxiety.

"And he hasn't a coat and scarf like you and me," Mun Bun said. "Maybe he hasn't any Grandma Bell to knit scarfs for him."

"I believe we ought to help him, Mun Bun," said Margy, decidedly. "We have plenty of coats."

"And scarfs," agreed Mun Bun. "Let's."

So they immediately left the room quite unnoticed by the older people in it. This is a remarkable fact. Whenever Margy and Mun Bun had mischief in mind they never asked Mother about it. Now, why was that, do you suppose?

The two little ones went swiftly downstairs into the front hall. Both had coats and caps and scarfs hung on pegs in a little dressing-room near the big door. They knew that they should not touch the outer garments belonging to the older children; but they got their own wraps.

"Maybe he's too big for them," murmured Margy. "But I guess he can squeeze into the coats—into one of them, anyway."

"Course he can," said Mun Bun. "Mine's a nawful warm coat. And that black snowman isn't much bigger than I am, Margy."

"I don't know," said his sister slowly, for she was a little wiser than Mun Bun about most things. "Open the door."

Mun Bun could do that. This was the inside door, and they stepped into the vestibule. Pressing his face close to the glass of one of the outer doors, Mun Bun stared down at the "black snowman" on the step.

"He's going to sleep in the snow," said the little boy. "I guess we've got to wake him up, Margy."

He pounded on the glass with his fat fist. He knocked several times before the figure below even moved. Then the colored boy, who was not more than seventeen or eighteen, turned his head and looked up over his shoulder at the faces of the two children in the vestibule.

He was covered with snow. His face, though moderately black as a usual thing, was now gray with the cold. His black eyes, even, seemed faded. He was scantily clad, and his whole body was trembling with the cold.

"Come up here!" cried Mun Bun, beckoning to the strange boy. "Come up here!"

The boy in the snow seemed scarcely to understand. Or else he was so cold and exhausted that he could not immediately get up from the step on which he was sitting.
