roill-wheel, and actually does so a furlong lower 

 down. These cave-streams are not uncommon 

 in these parts, the Ombla near Eagusa, which 

 is navigable to its source, being the largest and 

 probably the best-known example. Nearer Mostar 

 than this is an instance of the opposite process — 

 the river Trebincica, after flowing for some fifty 

 miles, suddenly vanishes into an awsome cavern, 

 never to be seen again of mortal man. 



The origin of the particular stream of which I 

 write is no doubt the infiltration of the waters of 

 the great Mostarsko JBlato, or Mostar Marsh, from 

 which a mountain separates it. This marsh, 

 although quite a lake in winter, is quite dry in 

 summer,* but no doubt the water is contained 

 in subterranean reservoirs. The spring has now 

 been surrounded with a Lustgarten quite in the 

 German style, with a restauraut, etc., which seems 

 rather a pity. The water-s apply of Mostar has 

 long been obtained from this source, but of late 

 years elaborate filtering arrangements and new 

 pipes have been fitted up, forming one of the 

 sights which are always shown to the visitor to 

 Mostar. The pressure obtainable is nevertheless 

 so low that no water is laid on to the houses, but 

 must be fetched by hand from street taps. 



There are several of these cave-streams in the 

 immediate vicinity of Mostar. The largest and
