A statue of Rev. Mr. Walker, whose courage, fortitude, and apostolic influence saved the city, was long ago erected upon the bastion which bore the heaviest fire during the siege. His noble figure stands upon the top of a shaft ninety feet high in the attitude which he is said to have assumed in the most terrible emergency, to revive and sustain the faltering courage of his parishioners. In one hand he grasps a Bible; the other is pointing down the river toward the approaching squadron of deliverance in the distant bay. At another point upon the walls is a Gothic castellated structure erected by public subscription as a clubhouse for the boys and young men of Londonderry. It is known as Apprentices' Hall, and was erected as a memorial to the courage and foresight of a group of thirteen young apprentices who, during the excitement caused by the approach of the king's army, had the presence of mind to drop the heavy gate without instruction from their elders, and thus made it possible to defend the city against the assault. Lieutenant-Colonel Robert Lundy, who was in command of the garrison at the time, was a coward, and insisted upon surrendering the city to the king's army, but was prevented from doing so by Rev. Mr. Walker, rector of the Episcopal church, and Adam Murray, an elder in the Presbyterian church. Lundy persisted in his purpose, carried on secret negotiations with the enemy, and was preparing to open the gates when his intentions were discovered. He escaped in disguise by climbing down the branches of a pear tree which grew against the wall on the east side. Twice a year, on the 18th of December and the 12th of August, the dates of the beginning and the end of the siege, the apprentice boys of the city lead a procession of all the Protestant organizations to attend divine service at the Episcopal Cathedral and then pass the rest of the day as we celebrate the Fourth of July. At nightfall an effigy of Colonel Lundy is always burned in a prominent place. These celebrations are deplored by thoughtful people, as keeping alive religious animosities, but of recent years the collisions which used to occur between the Orange societies and the Roman Catholics have been avoided. The population of Londonderry is very largely Protestant. The cathedral is an ugly old building, but quite interesting because of its historic associations and the relics it contains.
