"There exists, evidently, some reluctance among the officers in command to a close inspection of these works by foreigners. An instance in point occurred to-day. There were two young men, Americans, looking at the fort. They had obtained permission, which is given in writing by the Quartermaster-General, to inspect the Signal-Station, etc., but they were observed with paper and pencil in hand, taking down particular memoranda of the fortification, the size of guns, their number, the positions of the ravelins and what not. As this was considered a palpable breach of courtesy, a sergeant tapped them on the shoulder and led them out of the gate, with a reprimand for what he called their want of good manners. It is a long time since anything of the kind has occurred. "This Citadel is the place from which all vessels are signalled to the town. The signal stations are four in number; the first being at the Citadel, the second at 'York Redcut,' five miles down the harbor, the third, 'Camperdown,' some ten miles further, and the fourth, with which this last signals, is the island of 'Sambro,' ten miles south of the entrance to the harbor. The system is carried on by means of a series of black balls, which are hoisted in different positions upon two yard-arms, a long and a short one, placed one above the other on a tall flag-staff. The communication is very rapid, and is exempt from liability to mistakes. A sentence transmitting an order of any kind from one of the lower stations is sent and received in less than two minutes. The distance from 'Sambro,' the outer station, is about twenty miles from the Citadel. Maryatt's code of marine signals is in use here. The new marine code, lately issued under the auspices of the London Board of Trade, 'for all nations,' is pronounced by the operator as too complicated to become of any practical use, necessitating, as it would, the employment of a 'flag-lieutenant' on board every ship, who should do nothing but the signalling, since not one captain in a hundred would ever have the time or patience to acquaint himself with its mysteries. "Some works of internal improvement are in progress, which will be important in promoting the prosperity and in developing the resources of this Province. A railroad across the Isthmus to Truro, with a branch-road to Windsor, will connect the interior towns with Halifax, and furnish _modern_ facilities for communication with the other Provinces and with the States. Twenty-two miles of the road are already completed, and the remainder will be finished soon. A canal is also in progress from the head of Halifax harbor (north side) in the direction of Truro, which is to connect a remarkable chain of lakes with the Shubenacadie River, which empties into Minas' Basin at the head of the Bay of Fundy. Great results are anticipated in favor of the farming and other interests along its route. The work is in an advanced stage towards completion.
