When it is considered that Germany maintains with the colours a force of 600,000 men at a cost of £29,000,000, that France maintains 550,000 for £27,000,000, and that Italy maintains 221,000 for £7,500,000, it cannot be admitted that Great Britain would be unable to maintain 220,000 officers and men at an annual cost of £17,500,000, and the probability is that with effective administration this cost could be considerably reduced. It may at first sight seem that the logical course would have been to assume two years' service in the infantry and three years' service in the mounted arms, in accord with the German practice, but there are several reasons that appear to me to make such a proposal unnecessary. In the first place, Great Britain's principal weapon must always be her navy, while Germany's principal weapon will always be her army, which guarantees the integrity of her three frontiers and also guards her against invasion from oversea. Germany's navy comes only in the second place in any scheme for a German war, while in any scheme for a British war the navy must come in the first place and the army in the second. The German practice for many years was to retain the bulk of the men for three years with the colours. It was believed by the older generation of soldiers that any reduction of this period would compromise that cohesion of the troops which is the characteristic mark of a disciplined army. But the views of the younger men prevailed and the period has been reduced by a third. The reduction of time has, however, placed a heavier responsibility upon the body of professional instructors.
