“I guess they won’t get hurt,” she remarked.

“Well, they can’t harm the hay!” chuckled Zeek.

So the two smaller twins, with shouts of delight, climbed up in the haymow where there were great piles of the dried, sweet-smelling grass which the horses, cows, and sheep would eat when winter came, and when there was no longer green fodder in the fields.

Bert and Nan thought themselves a little too old for this kind of fun—at least, when there were older folks around. Though undoubtedly if just the four twins had been in the barn, the two larger ones would have enjoyed doing what Flossie and Freddie were doing.

These two scrambled up to the highest point of one of the hay piles and then slid down, the hay being almost as slippery as a hill covered with snow.

Bert and Nan wandered about the barn, looking at the different things. Bert wished there were some horses he might view, but the farm animals were kept in another building, this large one being used for the storage of hay and other crops.

Presently Nan, who was peering about along the edge of the hay mow, gave an exclamation of surprise.

“What’s the matter?” asked Bert.

“Look!” whispered Nan, pointing down through a small opening in the floor. “There’s a hen on her nest. Maybe she’s laying an egg!”

“Maybe,” agreed Bert. “If she is we mustn’t disturb her.”
