"Not far distant from High Falls," said John Landis, when all were comfortably seated near the table, with a sandwich in hand, "is a place called Roaring Rocks, also a freak of nature. I remember, when a boy, I always went there in the fall of the year, after the first hard frost, to pick persimmons. The water could he distinctly heard running underneath the rocks at a considerable depth."

Ralph Jackson remarked to Aunt Sarah: "I never imagined there were so many interesting, natural features right here in Bucks County."

"Oh, yes," exclaimed the impressible Fritz Schmidt, "we have a few things besides pigs and potatoes."

"Yes, Ralph," said the Professor, "there are still several places of interest you will like to see. 'Stony Garden' is another very interesting freak of nature. It is about two and a half miles from the small town of 'Snitzbachsville,' as Fritz calls the hamlet, and 'tis a wild spot. About an acre is covered with trap rock. The stones are of odd shapes and sizes and appear as if thrown into the forest in the wildest confusion. No earth or vegetation is found about them. 'Tis said the rocks are similar to those found at Fingal's Cave, Ireland, and also at the Palisades on the Hudson, and are not found anywhere else in this section of the country."

"And Ralph," said Fritz, "I want to show you 'Big Rock,' at Avondale, where a party of us boys camped one summer for two weeks. Oh! but I remember the good pies given us by a farmer's wife who sold us milk and eggs, and who lived just across the fields from our camp."

"I think," said John Landis, "it is time we began hitching up our horses and starting for home. We have a long drive before us, and, therefore, must make an early start. Sarah, get the rest of the party together and pack up your traps."

At that moment the Professor came in sight with an armful of ferns, the rich loam adhering to their roots, and said: "I'm sure these will grow." Later he planted them on a shady side of the old farm house at "Five Oaks," where they are growing today. Professor Schmidt, after a diligent search, had found clinging to a rock a fine specimen of "Seedum Rhodiola," which he explained had never been found growing in any locality in the United States except Maine. Little Pauline, with a handful of flowers and weeds, came trotting after Mary, who carried an armful of creeping evergreen called partridge berry, which bears numerous small, bright, scarlet berries later in the season. Ralph walked by her side with a basket filled to overflowing with quantities of small ferns and rock moss, with which to border the edge of the waiter on which Mary intended planting ferns; tree moss or lichens, hepaticas, wild violets, pipsissewa or false wintergreen, with dark green, waxy leaves veined with a lighter shade of green; and wild pink geraniums, the foliage of which is prettier than the pink blossoms seen later, and they grow readily when transplanted.

Aunt Sarah had taught Mary how to make a beautiful little home-made fernery. By planting these all on a large waiter, banking moss around the edges to keep them moist and by planting them early, they would be growing finely when taken by her to the city in the fall of the year—a pleasant reminder of her trip to the "Narrows" of the Delaware River. Frau Schmidt brought up the rear, carrying huge bunches of mint, pennyroyal and the useful herb called "Quaker Bonnet."
