The whole slope of Stall Moor towards the south is strewn with hut circles, and between the Yealm and Broadall Lake is a pound containing several. On the further side of the stream is another pound, at which begins a singular wall that extends for over three miles as far as the Plym at Trowlesworthy Warren. For what purpose this wall was erected--whether as a boundary, or whether for defence--cannot be determined. It is in connection with several pounds and clusters of hut circles. In the valley of Hawns and Dendles is a pretty cascade, a great haunt of the tripper, who ravages the Yealm valley and tears up and carries off the ferns and roots of wild flowers. A few instances of the habits of the tripper may not seem amiss, as exhibited in the Yealm valley. Blachford was the residence of the late Lord Blachford, the friend of Gladstone. One day my lady saw a woman--a tripper--in front of the house, where there is a rockery, tearing up ferns. Lady Blachford rushed forth to interfere. "Oh!" said the tripper, "I only did it so as to get a sight of Lord Blachford. I thought if I executed some mischief I might draw him forth." A peculiarly fine rhododendron grew in front of the vicarage. It attracted the tripper by its beautiful masses of flower. One evening an individual of this not uncommon species proceeded to tear it up, assisted by trowel and knife; and finally having hacked through the roots, carried it off; but finding the load burdensome at the first hill, threw it away. A gentleman residing further down the valley was cultivating a rare flowering shrub. After seven years it put forth its tassels of bloom. He tarried a day or two before gathering the blossoms till they were fully out. His wife was an invalid, and he purposed showing them to her when in their full perfection. But before he carried his purpose into execution, he went to Cornwood Station to meet a friend, when he perceived a "lady" on the platform with her hands full of the flowers. He approached her and civilly inquired where she had obtained the beautiful bunches. "Oh! they were growing in Mr. P.'s ground, so I went in and gathered them. I know Mr. P. well, and I am convinced he would not object." "You have the advantage of me, madam. I am Mr. P. But to a lady, as to a Christian, all things are lawful, though all things may not be expedient." A friend threw open his grounds to a great party of school teachers and their scholars. The neighbourhood had been denuded of the _Osmunda regalis_ by the tripper, but the beautiful fern had a sanctuary in his preserves. However, the visitors dug up, tore away, and destroyed his plants wholesale, and returned to town burdened with the wreckage. The _Osmunda_ is a slow grower, and takes many years to reach maturity.
