It is about ten feet square, and its walls, like those of the passage, are formed by huge blocks of stone set on end. Then other slabs were laid a-top them, and then on one another, each slab overlapping by eight or ten inches the one below, until a last great stone closed the central aperture and the roof was done. In the centre the chamber is about twelve feet high. Many of the stones are carved with spirals and concentric circles and wheel-crosses and Ogham writing—yes, and with the initials of hundreds of vandals!

In the centre of the floor is a shallow stone basin, about four feet square, used perhaps for some ceremony in connection with the burials—sacrifice naturally suggests itself, such as tradition connects with Druid worship; and opening from the chamber are three recesses, about six feet deep, also constructed of gigantic stones, and in these, it is surmised, the ashes of the dead were laid. From one of these recesses a passage, whose floor is a single cyclopean stone eight feet long, leads to another recess, smaller than the first ones. When the tomb was first entered, little heaps of burned bones were found, many of them human—for it should be remembered that the ancient Irish burned their dead before enclosing them in cists or burying them in tumuli. There were also unburned bones of pigs and deer and birds, and glass and amber beads, and copper pins and rings; and before the Danes despoiled it, there were doubtless torques of gold, and brooches set with jewels—but the robbers left nothing of that sort behind them.

Nobody knows when this mound was built; but the men who cut the spirals and circles—and in one place a leaf, not incised, but standing out in bold relief—must have had tools of iron or bronze to work with; so the date of the mound's erection can be fixed approximately at about the beginning of the Christian era. For the rest, all is legend. But as one stands there in that cyclopean chamber, the wonder of the thing, its uncanniness, its mystery, grow more and more overwhelming, until one peers around nervously, in the dim and wavering candle-light, expecting to see I know not what. With me, that sensation passed; for I happened suddenly to remember how George Moore and A. E. made a pilgrimage to this spot, one day, and sat in this dark chamber, cross-legged like Yogin, trying to evoke the spirits of the Druids, and just when they were about to succeed, or so it seemed, the vision was shattered by the arrival of two portly Presbyterian preachers.

There is another entrance to the tumulus, about half way up, which opens into smaller and probably more recent chambers; and after a glance at them, we clambered to the top. Far off to the west, we could see the hill of Tara, where the old kings who are buried here held their court and gave great banquets in a hall seven hundred feet long, of which scarce a trace remains; and a little nearer, to the north, is the hill of Slane, where, on that Easter eve sixteen centuries ago, St. Patrick lighted his first Paschal fire in Ireland, in defiance of a Druidic law which decreed that in this season of the Festival of Spring, no man should kindle a fire in Meath until the sacred beacon blazed from Tara. You may guess the consternation of the priests when, through the gathering twilight, they first glimpsed that little flame which Patrick had kindled on the summit of Slane, just across the valley. That, I think, is easily the most breathless and dramatic moment in Irish history. The king sent his warriors to see what this defiance meant, and Patrick was brought to Tara, and he came into the assembly chanting a verse of Scripture: "Some in chariots and some on horses, but we in the name of the Lord our God." And so his mission began.

On the other side of the mound, across a field and beyond a wall, I could see what seemed to be an ivy-draped ruin, and I asked our guide what it might be, and she said it was the birthplace of John Boyle O'Reilly. It was but a short walk, and my companion said he would wait for me; so I hastened down the mound and across the field and over the wall, and found that what I had seen was indeed a tall old house, draped with ivy and falling into ruin. Just back of it is a church, also in ruins, and again its wall is a granite monument to O'Reilly, more remarkable for its size than for any other quality. There is a bust of the poet at the top, and on either side a weeping female figure, and a long inscription in Gaelic, which of course I couldn't read; and which may have been very eloquent. But if it had been for me to write his epitaph, I would have chosen a single verse of his as all-sufficient:

Kindness is the Word.

Then, as I was wading out through the meadow to get a picture of the house, I met with a misadventure, for, disturbed by my passage, a bee started up out of the grass, struck me on the end of the nose, clung wildly there an instant, and then stung viciously. It was with tears of anguish streaming down my cheeks that I snapped the picture opposite the preceding page.

Dowth Castle is not the ancestral home of the O'Reillys; that stood on Tullymongan, above the town of Cavan, of which they were lords for perhaps a thousand years. Dowth Castle, on the other hand, was built by Hugh de Lacy, as an outpost of the English pale; but it came at last into the hands of an eccentric Irishman who, about a century ago, bequeathed it and some of the land about it as a school for orphans and a refuge for widows. The Netterville Institution, as it was called, came to comprise also a National school, and of this school John Boyle O'Reilly's father, William David O'Reilly, was master for thirty-five years. He and his wife lived in the castle, here in 1844 the poet was born, and here he spent the first eleven years of his life. What fate finally overtook the castle I don't know, but only the ivy-draped outer walls remain. The trim modern buildings of the Institution cluster in its shadow.

I made my way back to the car, where my companion, who was not interested in O'Reilly, was awaiting me somewhat impatiently, and I think he regarded the bee which had stung me as an agent of Providence. But we set off again, and the car climbed up and up to the summit of the ridge which overlooks the river; and presently we were rolling along a narrow road bordered with lofty elms, and then, in a broad pasture to our right, we saw another mound, far larger than the first, and knew that it was Newgrange.
