Shannon #1

Shannon, the largest river of Ireland, rises at the foot of Mt. Cuilcagh in the N. W. part of the county Cavan, flows S. W. for a few miles to Lough Allen, thence by a circuitous but generally S. course to Lough Derg, passing through Lough Ree, and thence S. S. W. to Limerick, below which the river, here called the Lower Shannon, flows W. S. W. through a broad estuary to the Atlantic. Its total length is about 250 m. Portions of its course are very picturesque. Its largest affluent is the Suck, which enters it from the west between Loughs Ree and Derg; others are the Boyle, Fergus, Inny, Brosna, Mulkear, and Maig. The principal towns on its banks besides Limerick are Leitrim, Carrick, Athlone, and Killa-loe. The tides in the estuary of the Shannon vary between 14 and 18 ft., and vessels of 400 tons can ascend as far as Limerick; the navigation has been improved throughout the entire length at a cost of about £500,000, and parliament in 1874 appropriated £300,000 for its further improvement; and canals connect it with many parts of Ireland.
