Leaving Nevresign one crosses two mountains, which, with the exception of about an hour and a half distance, are traversed by a road. Save one in course of construction from Mostar to Metcovich, it is the only attempt at road-making in the province. It is bad enough, as all Turkish roads are, their engineers having not the slightest idea of levelling. They take the country as they find it, apparently thinking that a zigzag, no matter at what slope the angles may be, is the highest triumph of their art. Until our arrival at Blagai, six miles from Mostar, an escort was deemed necessary, though it was really of not the slightest use, since the rebels, if so inclined, might have disposed of the whole party without once showing themselves. On nearing Mostar I looked with curiosity for any signs of progress in the new powder magazine or barracks, which are situated in the plain outside the town. They both appeared in precisely the same condition as when I left, save for the absence of some hundreds of ponies, which were at that moment eating mouldy hay at Gasko and its vicinity. In the barrack square several block-houses which Omer Pacha had ordered appeared to be in a state of completion. These are made of wood and have two stories, each house being capable of containing about two companies of infantry. The walls are loopholed and of sufficient thickness to resist musket balls: the use to which they were to be applied was the protection of working parties and small detachments during the construction of more permanent defences; and as the rebels are without carcases or liquid fire-balls or other scientific implements of destruction, it is possible that they may answer their purpose well enough.
