A peat bog is not always in a hollow, but often on a hillside, and sometimes at considerable height, which contradicts the theory that bogs are due to defective drainage. Science long ago determined that Irish peat was the accumulation of a peculiar kind of moss which grows like a coral bank in the damp soil, and continues to pile up in layers year after year, century after century, until it forms a solid mass, several feet thick, seventy per cent moisture and thirty per cent fibre, which burns slowly and furnishes a high degree of heat. We see bogs on all sides of us where the peat is three and four feet thick, and with a long straight spade that is as sharp as a knife, it is cut into blocks about eight or ten inches long and about four inches square. A sharp spade will slice it just as a knife would cut cheese or butter, and after the blocks have lain on the ground a while they are stacked up on end in little piles to dry. Then, when they have been exposed to the weather for three or four weeks, they are stacked in larger piles, from which they are carted away and sold or used as they are needed.

Four tons of peat are equal in caloric energy to one ton of coal. I noticed in the papers that a bill is pending before the House of Commons to grant a charter to a company to erect a station in a bog near Robertson, Kings County, twenty-five miles from Dublin, for generating electricity from peat, the power to be transmitted to Dublin and the suburban towns for lighting, transportation, and manufacturing purposes. Several other projects of a similar sort have been suggested for utilizing the peat at the bog instead of carting it into town.
Beyond the peat beds rises a chain of low mountains with a curious profile that runs west of the town of Templemore. Like every other freak of nature in Ireland, they are the scenes of many interesting legends. The highest peak is called "The Devil's Bit," and the queer shape is accounted for by the fact that the Prince of Darkness in a fit of hunger and fatigue once took a bite out of the mountain, and, not finding it to his taste, spat it out again some miles to the eastward, where it is now famous as the Rock of Cashel.
