"Went ashore after dinner, and visited the fort, which is only partly completed: it is a _flêche_ to the sea, with eight guns, twenty-four pounders, but without any land defences; the guns are mounted _en barbette_, without embrasures, each upon a kind of movable stage, which stage wheeling upon a pivot in front, and traversing by means of wheels behind, can be pointed in any direction that may be thought necessary. Upon this stage, the gun-carriage moves forward and recoils, and the depth of the parapet shelters the men even better than an embrasure. At a little distance from this battery they are building a Martello tower, which is to cross the fire of the battery, and also that of another projected tower upon the opposite point of the bay. The expedience of these towers seems excessively problematical. Supposing them impregnable, or nearly so, a garrison of fourteen or fifteen men may be always blockaded by a very trifling number, while the enemy dispose of all in the vicinity at their pleasure. In the case of Long-Hope, for instance, a frigate might disembark 100 men, take the fort in the rear, where it is undefended even by a palisade, destroy the magazines, spike and dismount the cannon, carry off or cut out any vessels in the roadstead, and accomplish all the purposes that could bring them to so remote a spot, in spite of a sergeant's party in the Martello tower, and without troubling themselves about them at all. Meanwhile, Long-Hope will one day turn out a flourishing place; there will soon be taverns and slop-shops, where sailors rendezvous in such numbers; then will come quays, docks, and warehouses; and then a thriving town. Amen, so be it. This is the first fine day we have enjoyed to an end since Sunday, 31st ult. Rainy, cold, and hazy, have been our voyages around these wild islands; I hope the weather begins to mend, though Mr. Wilson, our master, threatens a breeze to-morrow. We are to attempt the Skerries, if possible; if not, we will, I believe, go to Stromness.
