The first volume of the present work, the only one yet published, brings down the history of Maryland to the establishment of the state government. Besides a historical view of the transactions preceding this era, it contains, in an introduction, a view of the territorial limits of the colony as defined in the first grant to the proprietary, and of the disputes with neighbouring grantees by which they were successively retrenched. Two other chapters of the introduction are occupied with a sketch of the civil divisions of the state, and an essay on the sources of its laws. Appended to the historical sketch is a view of the distribution of the legislative power, of the organization of the two houses of assembly, their respective and collective powers, and the privileges of their members. This plan involves a critical inquiry into the political laws of the state, and a laborious examination of its records. The diligence with which the writer seems to have executed his task, is a voucher of his accuracy; and the body of information thus collected with painful research, will probably establish his work as one of authentic reference. This original collation of the materials from which history is _distilled_, includes a labour, and deserves a praise, which readers can hardly estimate competently. The writer's style is vigorous, but wants compression; he is occasionally inaccurate, but is often lively and striking; his scriptural phraseology is superabundant. As he understands the period and the men he describes, his views and reflections are just. The narrative would have been enlivened by a little more individuality in the portraits of the actors; but though some of the materials for this were probably at his command, at least as to the more recent ones, we are aware of the reasons which impose on this head, a partial silence on the historian of an age not remote. It is respecting its personages that Christina's saying of history is more emphatically true;--"_Chi lo sa, non scrive; chi lo scrive, no sa._"--"The one who knows it, does not write; the one who writes it, knows it not." It was this Mr. Jefferson meant, when he said the history of the revolution had never been written, and never would be written. On the whole, Mr. M'Mahon's is a valuable contribution to an interesting theme, and we must increase the obligations we are under to him, by borrowing the copious materials he supplies, for a hasty sketch, or rather some selections of the colonial history of Maryland, in which we shall take the liberty to make, without scruple, free use both of his language and thoughts.
