"You think there is a difference between brothers and brothers," said Flora laughing. "Well, my experience is what I tell you." "Ditto," said Maggie suddenly, "are there any such stones as those queer stone-houses in this country?" "Not that ever I heard of, Maggie. But in the old world, as it is called, there are a great many, scattered over a great many countries. Not all just like the stone-houses. Some are just single stones set up on end. Some are two laid together, one resting on the other slantwise; the stone-houses in Lüneburg seem to have been made of nine stones, one lying on eight." "Did people offer human sacrifices on all of them?" "I fancy not. But I believe it is tolerably uncertain. Did you never see a picture of Stonehenge?" Maggie knew nothing about Stonehenge. Meredith went to the bookcases again and got another volume. This contained many illustrations of old stone monuments of various kinds, and he and Maggie were soon absorbed in studying them. "There!" cried Maggie, as he opened at one of the earliest illustrations, "there, Ditto! that is very like--_very_ like--what you read of the stone-houses. Isn't it?" "Fearfully like," said Meredith. "This is in Ireland. I dare say some of those old Druids sacrificed men on it." "How could they set it up so? Look, Ditto--the top stone rests just on one point at the lowest end. I should think it would topple down." "It has stood hundreds of years, Maggie, and will stand for all time--unless an earthquake shakes it down. This dolmen is made of four stones." "What is a dolmen?" "This is one. It says here in a note, that the name comes 'from the Celtic word _Daul_, a table, and _Chen_ or _Chaen_, a stone.' A stone table. And it says here that there are probably a hundred of such dolmens in Great Britain and Ireland. How ever did the builders get that enormous block poised on the tips of the other three?"
