The Pirate's Progress. By William Archer. (Matto and Windus. 6d.

net. )—This instructive pamphlet describes the German submarine warfare in its successive phases of ever-increasing inhumanity. Mr. Archer gives details of some typical cases, such as the • Lusitania,' the Persia,' the ' Sussex,' and the ' Belgian Prince,' in the course of his narrative. Sailors will never forget these horrors ; to landsmen with short memories Mr. Archer's well-written pamphlet may be commended.
