How the Swedish system was introduced into the British Navy and substituted, in large part, for the Maclaren gymnastics in the Army, may be told in a few words. Commander N. C. Palmer of the Navy spent some weeks in Stockholm in the autumn of 1902, in order to study the organization and management of instruction in gymnastics there, and upon his return set in motion plans for the training of instructors from among officers and non-commissioned officers. In the summer of 1903 Allan Broman was put in charge of the first course at Portsmouth, given to sixty officers in the British Navy. That same year a _Handbook of Physical Training_, published by authority of the Lords Commissioners of the Admiralty, was issued.[174] Part I (pp. 4-73) is evidently based upon the Swedish Army and Navy Manual of 1902 (see p. 163), in both text and illustrations. A new Handbook, much enlarged and altogether Swedish, was published in 1910, the work of Lieutenant Lockhart Leith, who during a winter in Stockholm had taken part in the exercises at the Central Institute of Gymnastics. In 1906 the Army authorities decided to introduce the same system, but instead of going to Sweden they applied to the Danish government for a man capable of teaching it at the Aldershot training school for instructors. H. P. Langkilde (p. 192) was selected for the task. He began a course with the sixteen teachers at the school in August, and the next month a regular four-months’ course with non-commissioned officers. By the first of the next year (1907) the transition to the new system was complete. A _Manual of Physical Training_, worked out by Major Moore in collaboration with Langkilde on the basis of the Danish _Haandbog_ of 1899, the Army and Navy Manual (Danish) of 1905, and the books of Knudsen was published in 1908.[175]
