Having in these high attributes of a great military Commander made ourselves acquainted with those qualities in which heart and head co-operate, we now come to a speciality of military activity which perhaps may be looked upon as the most marked if it is not the most important, and which only makes a demand on the power of the mind without regard to the forces of feelings.  It is the connection which exists between War and country or ground.

This connection is, in the first place, a permanent condition of War, for it is impossible to imagine our organised Armies effecting any operation otherwise than in some given space; it is, secondly, of the most decisive importance, because it modifies, at times completely alters, the action of all forces; thirdly, while on the one hand it often concerns the most minute features of locality, on the other it may apply to immense tracts of country.

In this manner a great peculiarity is given to the effect of this connection of War with country and ground.  If we think of other occupations of man which have a relation to these objects, on horticulture, agriculture, on building houses and hydraulic works, on mining, on the chase, and forestry, they are all confined within very limited spaces which may be soon explored with sufficient exactness.  But the Commander in War must commit the business he has in hand to a corresponding space which his eye cannot survey, which the keenest zeal cannot always explore, and with which, owing to the constant changes taking place, he can also seldom become properly acquainted.  Certainly the enemy generally is in the same situation; still, in the first place, the difficulty, although common to both, is not the less a difficulty, and he who by talent and practice overcomes it will have a great advantage on his side; secondly, this equality of the difficulty on both sides is merely an abstract supposition which is rarely realised in the particular case, as one of the two opponents (the defensive) usually knows much more of the locality than his adversary.

This very peculiar difficulty must be overcome by a natural mental gift of a special kind which is known by the—­too restricted—­term of Orisinn sense of locality.  It is the power of quickly forming a correct geometrical idea of any portion of country, and consequently of being able to find one’s place in it exactly at any time.  This is plainly an act of the imagination.  The perception no doubt is formed partly by means of the physical eye, partly by the mind, which fills up what is wanting with ideas derived from knowledge and experience, and out of the fragments visible to the physical eye forms a whole; but that this whole should present itself vividly to the reason, should become a picture, a mentally drawn map, that this picture should be fixed, that the details should never again separate themselves—­all that can only be effected by the mental faculty which we call imagination.  If some great poet or painter should feel hurt that
