THE MONTGOLFIANS

SIR,—May I supply the hot air to launch Mr. Peacock's balloon? He is mistaken. The LNER adopted the apple-green livery of the old Great Northern Railway. The NER green was indeed very similar, but a trifle lighter in shade.

Perhaps Mr. Sacheverell Sitwell will now say which railway company's engines he had in mind?—Yours faithfully,
