ANNEX.

Note by Petroleum (Warfare) Department.

Extensive experiments on beaches have established that it is practicable to create a fierce barrage of flame on the sea between high and low water marks in most conditions in which a landing could be made. When, however, there is surf the flame is less effective and further experiments have been carried out to see whether a flame barrage on shore just above high-water mark could be made.

A successful "beach flame barrage" on a 200 yard front has just been completed and will be available for viewing within a few days. This can be operated if desired in conjunction with sea flame by a simple system of valves.
