Ireland is situated in the North Atlantic, between the degrees fifty-one and a half and fifty-five and a half North, and five and a quarter and ten and a third West longitude from Greenwich. It is the last land usually seen by ships leaving the Old World, and the first by those who arrive there from the Northern ports of America. In size it is less than half as large as Britain, and in shape it may be compared to one of those shields which we see in coats-of-arms, the four Provinces—Ulster, Connaught, Leinster, and Munster—representing the four quarters of the shield. Around the borders of the country, generally near the coast, several ranges of hills and mountains rear their crests, every Province having one or more such groups. The West and South have, however, the largest and highest of these hills, from the sides of all which descend numerous rivers, flowing in various directions to the sea. Other rivers issue out of large lakes formed in the valleys, such as the Galway river which drains Lough Corrib, and the Bann which carries off the surplus waters of Lough Neagh (_Nay_). In a few districts where the fall for water is insufficient, marshes and swamps were long ago formed, of which the principal one occupies nearly 240,000 acres in the very heart of the country. It is called "the Bog of Allen," and, though quite useless for farming purposes, still serves to supply the surrounding district with fuel, nearly as well as coal mines do in other countries. In former times, Ireland was as well wooded as watered, though hardly a tree of the primitive forest now remains. One of the earliest names applied to it was "the wooded Island," and the export of timber and staves, as well as of the furs of wild animals, continued, until the beginning of the seventeenth century, to be a thriving branch of trade. But in a succession of civil and religious wars, the axe and the torch have done their work of destruction, so that the age of most of the wood now standing does not date above two or three generations back. Who were the first inhabitants of this Island, it is impossible to say, but we know it was inhabited at a very early period of the world's lifetime—probably as early as the time when Solomon the Wise, sat in Jerusalem on the throne of his father David. As we should not altogether reject, though neither are we bound to believe, the wild and uncertain traditions of which we have neither documentary nor monumental evidence, we will glance over rapidly what the old Bards and Story-tellers have handed down to us concerning Ireland before it became Christian.
