URI в художественном тексте

Обнаружил нечто похожее на адреса в художественном тексте. Приведу исследуемый отрывок рассказа Марка Твена:

It was summer time, and twilight. We were sitting on the porch of the farm-house, on the summit of the hill, and "Aunt Rachel" was sitting respectfully below our level, on the steps, -- for she was our servant, and colored. She was of mighty frame and stature; she was sixty years old, but her eye was undimmed and her strength unabated.

Ниже приведу URI, ведущие от большего к меньшему.
