Descripción

large folding chart printed in blue, some light creasing along central fold, upper panel of verso with advertisement for 'St. George Semaphore Signalling Instructor' machine laid down, foolscap 8vo (68.5 x 48 cm unfolded), original red wrappers printed in blue, illustration laid down to front, a little nicked and creased at extremities, good. A 'revised edition', though LibraryHub does not record an earlier one - it is institutionally scarce in any form. The author asserts that the present method is 'twice as rapid as the Morse system'; his chart illustrates 'the alphabet, numerals, and special signs' in semaphore - as produced via mechanical means at the head and then the corresponding manual positions in the main section of the chart. Henry Reginald von Donop Hardinge (1878-1956), an officer of the 4th Infantry, Hyderabad Contingent, India was from a distinguished military family; the inside cover advertises other of his guides to signalling.
