394 APPENDIX. 



the Adriatic to Albania, but its worst effects are 

 experienced in Istria. Such a bora as we experi- 

 enced at Mostar in the early part of the year '95, 

 when half the town was unroofed — the new half, 

 that is to say, for the low-lying Turkish houses, 

 with their covering of stone slabs, mostly escaped 

 — is not often known there, and, indeed, is said 

 not to have occurred more than twice since the 

 Austrian occupation. 



I have been told that the bora is really a violent 

 down-draught caused by the vast difference between 

 the high temperature of the Adriatic littoral and 

 the low one of the adjacent mountains, and some 

 confirmation of this theory seems to be found in 

 the fact that the bora is said only to continue at 

 Mostar as long as the snow lies on the mountains 

 beyond it. To this I cannot speak personally, for, 

 as has been seen, I was never in Mostar during 

 the summer. 



On the other hand, an Austrian naval officer 

 told me they suffered greatly from the bora when 

 lying on the Lower Danube. I am inclined, 

 however, to think that he was confusing it with 

 a very familiar acquaintance of English readers — 

 the east wind.
