How to keep ships' hulls free from corrosion and free from accretion below the waterline for a reasonable time has been a problem for admiralties and mercantile marine operators for many years but one which is now claimed to have been solved satisfactorily by the Dutch firm of Koninklijke Lak‐,Vernis‐en Verffabriek Molyn & Co. N. V., of Rotterdam.

In the protection against corrosion of lock gates and other harbour structures, the life expectation of the protection given is of major importance because of the high cost of drying off structures and repainting them. This paper discusses the factors involved and describes some case histories of marine protection.

Sheen Instruments last week held a very successful two‐day agents sales conference in Portsmouth, which was attended by their distributors from all over the world. The conference also marked the official launch of the new Sheen Automatic Panel Sprayer to agents and specially invited U.K. customers.
The Professor of Bacteriology at the Kansas Agricultural Experimental station gives here a survey of the modes of action of specified bacteria in causing materials breakdown, with particular reference to pipe coatings, and also covers the test procedures used and the reasons for their selection. The article contains the main substance of a paper published recently by Kansas State University, Manhattan, Kansas; the latter is closely associated with large‐scale projects in the investigation of underground corrosion.
Shipping is one of the major British industries and a valuable source of ‘invisible exports’ by virtue of its earnings of foreign currencies. One of the major costs incurred by shipping companies is that of preventing the corrosion of their vessels and at a rough estimate it is probable that something like £30 million is expended annually in countering the corrosion of ships and harbour installations. Ships are constructed mainly of steel and their protection is essentially a particular aspect of the problem of protecting steel against corrosion. Aluminium alloys and newer materials such as plastic sheets are being increasingly used on board ships, but these materials do not offer quite the same difficulty as regards protection nor is the problem yet of the same magnitude. Painting is the most widely used means of protection and the present article deals with some of the problems associated with the painting of ships from the point of view of a paint manufacturer.
