“No, dearie, I haven’t,” was the answer. “And I feel quite lost without them. I can’t read a word. You children haven’t seen them anywhere, have you?”

None of the Bobbseys had, though, led by Nan, Flossie and Freddie gave another search about the house and the side porch. But the old lady’s glasses seemed to have vanished completely, and she did not know what to do about getting another pair.

“I guess I’ll just have to wait until my doctor comes back in the fall,” she said, with a sigh.

The next day proved to be a bright and sunshiny one—just the best kind for a picnic.

Mrs. Watson decided to take Baby Jenny with them on the outing, and soon after breakfast she and the little one joined the Bobbsey family in Mr. Bobbsey’s auto. They were to go to a glen about ten miles away, there to spend the day. In the glen, or little valley between two high, rocky places, was a waterfall, much larger than the one in the brook where Bert had placed his wooden mill.

“I wish I had made a bigger paddle wheel so I could fasten it under the big waterfall we are going to see,” said Bert, when they were almost ready to start.

“It would have to be a big paddle, for there is quite a fall in Buttermilk Glen,” Mrs. Watson said, with a laugh.

“Why do they call it that?” asked Nan.

“Because some one thought the water, falling over the ledge of rocks, looked like buttermilk, I suppose,” was the answer. “Do you want to go to Nan?” the mother asked Baby Jenny who was holding out her hands toward Bert’s twin sister. “Well, I guess you may.” So, to her delight, Nan was allowed to hold the baby during part of the auto ride to Buttermilk Glen.

Baskets of food had been packed, for the picnic was to last all day and they would eat in the woods, the prospect of which gave the twins joy and delight.
