GARUMNA, a noble and navigable river of Gaul, which rising from the Pyrenees, formerly bounded Aquitain on the north (Cæsar); but by the new regulation of Augustus divided it in the middle, emptying itself, to the north of Burdegala, into the Aquitanic ocean. Now the Garonne. Mela observes concerning it, that unless it is swelled by winter rains, or the melting of the snow, it is for a great part of the year shoaly and scarce navigable: but when increased by the meeting tide, whereby its waters are repelled, it is somewhat fuller, and the farther the river advances, it is broader, till at length it resembles a large frith or arm of the sea; not only bearing large vessels, but also swelling like a raging sea, tosses them extremely, especially if the direction of the wind be one way and that of the current another.
