It took a month to build the sod house, during which time the family lived in the woods, sleeping in their beds in the wagons as they had done on their journey, and eating in the open under the spreading cottonwood trees.

The weather continued fine, and the family, in spite of their isolation, were very happy. They were busy all day long, and had always been one of those happy and united families who find their greatest happiness in one another.

Nina had come to be quite one of themselves now, and she and Ruth were seldom apart, while for Joe and Sam and Lige the girl showed a warm and grateful affection. She was devoted to Mrs. Peniman, and often sat at her feet or on the arm of the old rocking-chair with her arm about her neck, calling her "Mother Peniman," and showering upon her the love and tenderness she had always shown for her own unfortunate young mother.

When the walls of the sod house were completed the hardest part of the work was to come, and Joshua Peniman puzzled long as to how he was going to get the ridgepole in place without another man to help him. He felled a strong, straight young tree, about fifteen inches through, and carefully stripped the bark from it. To raise the pole the aid of the whole family was required. As there were no neighbors within many miles to call upon, the difficult and dangerous feat must be performed with what help was at hand. He first made skids and rolled the tree upon it. These skids he placed with one end resting on the wall, the other on the ground. Ropes were then fastened to it, and while Mrs. Peniman, Ruth, Nina, and Sam stood on the top of the wall and pulled the ropes, Joe, Lige, and their father, on the ground, lifted and pushed the pole from below.

Fortunately for the success of the operation life in the open air, constant exercise and hard work had hardened the muscles of all and made them equal to the exertion. It was a strenuous piece of work, but with much puffing and panting and laughter they kept doggedly at it, and before dusk had come they got the ridgepole in place, and the most difficult part of building the house was accomplished.

Next came the rafters, which were poles of young trees from four to six inches through, placed about fifteen inches apart. Over these were laid boughs, cut from the willow thicket, and these thickly overlaid with the dry prairie grass. When a thick, deep covering of this straw had been laid in place and carefully packed down, dirt to the depth of about a foot was piled upon it and beaten down hard with the spade.

Now they were ready for the doors and windows!

The proud architects of this mansion of "Nebraska marble"—consisting of every member of the family except little Mary and David—stood about and surveyed it with admiring eyes. Even Lige was converted and was now willing to admit that it was a great idea. The walls were even, straight, and true, its corners square, its whole appearance neat and workman-like.

Greatly to the boys' astonishment they found packed away on the very bottoms of the two wagons three sets of window-casings and two stout wooden doors.

"I never knew those were there!" cried Joe, as he saw his father haul them out. "How did you ever come to think of them?"
