The extent of the water system of a country and its distribution is always of the first importance. In this respect, too, Hungary has been blessed by nature. Of the sea she has but little; a small portion only of the Adriatic washes her shores, the so-called Hungarian Sea-Coast, where Fiume, the only important Hungarian seaport city, is situated. The country possesses also some interesting lakes; one, Lake Balaton, forty-seven miles long and nine miles wide, has the characteristics of the sea to such an extent that it is called the Hungarian Sea. In this extensive water is to be found the savory _fogas_ fish, and on its shores is situated Balaton-Füred, one of the favorite watering-places of Hungary, and near this place is the famous echo of Tihany. Another large lake is the Fertö (Neu-Siedler), eighteen miles long and about five miles wide, which became perfectly dry in 1863, so that even houses were built on its bed, but the waters have returned to it within the last few years. Several smaller lakes, besides the two mentioned, are scattered throughout the country. With rivers the country is abundantly supplied. Its mightiest stream is the Danube, after the Volga, the largest river in Europe. The whole of Hungary belongs to its basin. Its length in Hungary is 600 miles, and it leaves the country at Orsova, after having formed several islands in its course. The largest among these is the Great Csalló region, which contains two towns and over a hundred villages; and the most beautiful of them is Margit (Margaret) Island, near Buda-Pesth—quite a miniature paradise, frequented by a great many strangers, who come here to get the benefit of its excellent baths. Of the numerous affluents of the Danube the Theiss is the most important; it has its sources in the country and empties into the Danube on Hungarian soil, near Titel. It is navigable for steamships. The Save and Drave are after the Theiss the largest tributaries of the Danube. All these rivers send their waters, through the medium of the Danube, into the Black Sea.
