It is somewhat curious that, among the many questions which pertain to the national life of Australia, little, if any, attention has been directed to the influences which the daily food and habitual dietary exercise upon the present, and in what way they will affect the future population. And yet it must be apparent that the life of a nation is moulded in no small degree by its daily fare, by its general food habits, and still more by the fact of its living in conformity with, or in direct opposition to, its climatic requirements.
