The analogy of the clam may not be convincing, but it may at least serve to suggest what may be the share played by habituation in the matter of national attachment. The young clam, after having passed the free-swimming phase of his life, as well as the period of attachment to the person of a carp or similar fish, drops to the bottom and attaches himself loosely in the place and station in life to which he has been led; and he loyally sticks to his particular patch of ooze and sand through good fortune and evil. It is, under Providence, something of a fortuitous matter where the given clam shall find a resting place for the sole of his foot, but it is also, after all, "his own, his native land" etc. It lies in the nature of a clam to attach himself after this fashion, loosely, to the bottom where he finds a living, and he would not be a "good clam and true" if he failed to do so; but the particular spot for which he forms this attachment is not of the essence of the case. At least, so they say. It may be, as good men appear to believe or know, that all men of sound, or at least those of average, mind will necessarily be of a patriotic temper and be attached by ties of loyalty to some particular national establishment, ordinarily the particular establishment which is formally identified with the land in which they live; although it is always possible that a given individual may be an alien in the land, and so may owe allegiance to and be ruled by a patriotic attachment to another national establishment, to which the conventionalities governing his special case have assigned him as his own proper nation. The analogy of the clam evidently does not cover the case. The patriotic citizen is attached to his own proper nationality not altogether by the accident of domicile, but rather by the conventions, legal or customary, which assign him to this or that national establishment according to certain principles of use and wont.
