[To Tax Eorros or rue "srevrxroa."] SIR,—I should like- to
endorse all that Mr. F. D. Drewitt says in hie letter in your last issue. I wish I could agree with your note, but the experience of seven years has given me the knowledge that use increases the visibility of the top of the cap, because the material becomes lighter in colour. Since the middle of August I have daily seen troops passing down the road at a short distance from my house. From the ground floor the top of the cap is visible as an ellipse through the trees, and in the case of cyclist corps is the only indication of their presence. From the first floor the discs are targets. To an aeroplane or an observer on rising ground the cap locates the wearer. If he stoops or turns round, the top of a cap is a moving mirror. It would seem to be a source of grave danger on active service. It is to be hoped that some definite and immediate steps will be taken to lessen or eliminate this
peril to our soldiers—I am, Sir, &e., G. W. S. H.
