I have sometimes found it difficult to write on the topics to which the remaining and larger part of the books is devoted, with sufficient fullness to convey a definite im pression of their place in the general scheme of Government, yet not 'on such a scale as would destroy the proportions of my plan or would suggest that I am giving information which is more properly sought for in special treatises. Hence perhaps the reader may ask why, on some of these subjects, I have said so much; or why, having said so much, I have said no more. If I have induced him to seek for fuller knowledge I shall not have written in vain.
