Mr. Francis B. Cooke is an old hand at cruising in small yachts. He has given more good advice than most writers on this subject to young amateurs. In his latest book, Coastwise Cruising (Edward Arnold and Co., 12s. 6d.) he describes all the harbours from Erith in the Thames to Lowestoft. His sailing directions are greatly helped by clear drawings of the channels and a description of the principal marks. The book is a complete guide for the owners of small yachts who find their most convenient cruising ground in the Thames Estuary and the creeks of Essex and Suffolk. The marks for entering Bradwell Creek in the Blackwater river change from time to time, but we can guarantee from experience that Mr. Cooke supplies the latest information.
