missioners for Northern Lights, look well after the literary entertainment of the watchers in our lonely lighthouses. Imagine the exquisite horror of being able to read Poe's Fall of the House of Usher, or Arthur Gordon Pym, in an isolated lighthouse during a dreadlful storm! It is doubtful, however, if the provision of libraries made by the Admiralty and the War Office for the inhabitants of our barracks and ships of war is at all adequate. The best technical collections are not freely at the call of the common soldier or sailor, and consequently their value must be greatly limited. It is not proposed to consider the needs of every variety of special library, because to a great extent the chapters on the small municipal library will answer every ordinary question.
