The Story of Our Submarines. By Klaxon. (Blackwood. 6s. net.)—This

book, written by an expert, and based largely on official records, is of great interest. The author maintains that our submarine service was far better than the enemy's, and he gives convincing proof of the statement. The continuous patrols maintained by our submarines in the Bight must have been wearisome, but were of incalculable value to the Grand Fleet., since every movement of the enemy was reported by wireless. The author says that Heligoland was virtually useless to the enemy, and would have been a source of danger to us if we had had it. British submarines, he declares, torpedoed and sank eighteen ' '-boats, and lost only five of their number in this way. " Klaxon " describes with great spirit some typical actions both in the North Sea and in the Mediterranean. His book is one of the best yet written on the naval side of the war.
