the whole accomplished, that foreign powers had not time to intervene; and it is said, that, when the French messenger went to seek the insurgents with his proposals, they were already fugitives. In honor of his services in this contest, the Federal Diet voted General Dufour a sabre of honor and a donative of forty thousand francs. General Dufour's "Strategy and Tactics." is evidently the fruit of an attentive study of the best examples and authorities of all ages. He has avoided mere theories and fine writing, and has aimed to present a work practical in its treatment and application. The lessons of history have been his guide; his precepts are fortified by pertinent examples from the campaigns of the best generals, and we may study them with confidence that when put to the actual test they will not fail. The distinction between strategy and tactics, not always clearly understood, is in substance drawn thus by General Dufour. Strategy involves general movements and the general arrangement of campaigns, depending chiefly upon the topographical features of the country which is the scene of operations, while tactics relate to the minor details of campaigns, as the disposition for marches and battles, the arrangement of camps, etc. Strategy depends upon circumstances fixed in their nature, and is the same always and everywhere; but tactics must be modified to suit degree of skill, arms, and manner of fighting of the combatants. Hence, "much instruction in strategy may be derived from the study of history; but very grave errors will result, if we attempt to apply in the armies of the present day the tactics of the ancients. This fault has been committed by more than one man of merit, for want of reflection upon the great difference between our missile weapons and those of the ancients, and upon the resulting differences in the arrangement of troops for combat." Our own military leaders have not entirely avoided mistakes of this kind in the conduct of the present war. The treatise before us elucidates the general principles of strategy and tactics, and applies them to the different classes of field operations, without entering into details, or describing the minor manœuvres, which belong more appropri-, ately to another class of works. The first chapter treats of bases and lines of operations, strategic points, plans of offensive and defensive campaigns, and strategical operations. Under the last head are embraced forward movements and retreats, diversions, (combined movements and detachments,) the pursuit of a defeated enemy, and the holding of a conquered country. The great lesson of the chapter, prominent in almost every paragraph, is the necessity of concentration. Divergent marches, scattering of forces, unless ample facilities are secured for a speedy rally, when necessary, to a common point, are among the most fruitful sources of disaster. The organization of armies next receives attention. The explanation of the composition of the army, its divisions and subdivisions, and the adjustment of the relative proportions of the different classes of troops, is brief and lucid. In the article on the formation of troops the relative merits of formation in two ranks or three are discussed at length. Under the head of marches and manœuvres are considered the rules by which these movements should be conducted. These apply to the adjustment of the columns, and the division, when necessary, of the forces upon different roads in order to facilitate progress and make subsistence more easy, the detailing of scouts and advance and rear guards, etc. The adaptation of these rules to forward movements and battles leads to a description of the order of march of the division, the precautions to be observed in the passage of defiles, bridges, woods, and rivers, and when the column has arrived in the presence of the enemy, and the conduct of flank marches, marches in retreat, and the simultaneous movement of several columns. The importance of precautions against surprise, of preserving the mobility of the columns, and of providing for concentration on short notice whenever it may be necessary, is not lost sight of, but is dwelt upon with great frequency. But military rules are not more inflexible than other human rules. Though they are based upon fixed principles, cases may, and do, arise when they cannot be strictly adhered to,- sometimes when they ought not to be. When should they be strictly observed? When and how far is it prudent to depart from them? "These questions," says General stances, which are always different, must decide in each particular case that arises. Here is the place for a general to show his ability. The military art would not be so difficult in practice, and those who have become so distinguished in it would not have acquired their renown, had it been a thing of invariable rules. To be really a great general, a man must have great tact and discernment in order to adopt the best plan in each case as it presents itself; he must have a ready coup d'œil, so as to do the right thing at the right time and place; for what is excellent one day may be very injurious the next. The plans of a great captain seem like inspirations, so rapid are the operations of the mind from which they proceed: notwithstanding this, everything is taken into account and weighed; each circumstance is appreciated and properly estimated; objects which escape entirely the observation of ordinary minds may to him seem so important as to become the principal means of inducing him to pursue a particular course. As a necessary consequence, a deliberative council is a poor director of the operations of a campaign. As another consequence, no mere theorizer can be a great general." Battles, on which the fortune of the campaign must turn at last, receive a large share of attention. The decision of the question as to when they shall be fought, though sometimes admitting of no choice, is more often, with a skilful general, a matter of pure calculation, depending upon fixed principles, which General Dufour recites in a few brief, but suggestive sentences. His directions for the disposition and manoeuvres of the forces in both offensive and defensive battles are quite complete, though the thousand varying circumstances by which these may be modified, and which render it impossible for one battle to be a copy of another, can only be hinted at. Among the elements of a battle here considered are the disposition of the forces, the manner of bringing on and conducting the engagement, the manœuvres to change position on the field, bringing on reinforcements, seizing all advantages that may offer, and the manner of conducting pursuit or retreat. The attack and defence of mountains and rivers, of redoubts, houses, and villages, covering a siege, infantry, cavalry, and artillery combats and reconnoissances, each involve special principles, and are treated separately. In the course of the article on battles, some general observations are introduced on conducting manœuvres so as to insure promptness, security, and precision. The conduct of topographical reconnoissances is well explained by means of a map of a supposed district of country, with marked features, which is to be examined. On this the course of the reconnoitring party, as it goes over the whole, is traced step by step, and fully explained in the letter-press. In the concluding chapter the author treats of convoys, ambuscades, advance posts, the laying-out of camps, and giving rest to troops. Such are the outlines of a subject which General Dufour has handled in a masterly manner. His maxims are practical in their bearing, they commend themselves to our common sense as sound in principle, and are such as have received the indorsement of the best authorities. His style is clear and comprehensive; nothing superfluous is inserted, nothing need be added to make the subject more clear. The illustrations, which are given wher ever they are needed, are simple and clear; the explanations are sufficient. This work will be a valuable manual to soldiers, and students will find it an excellent text-book. We hail it as an important addition to our growing military literature. THE student of Physical Geography must not expect to find in this massive book a systematic exposition of the science in the manner of Guyot and the French and German geographers; nor must he expect to see worked out on its pages the elaborate application of Geography to History, such as one day will be done, and such as was attempted, though with results of varied value and certainty, by the eloquent and plausible Buckle; but he will find an unexpected development of man's dominion over the world he inhabits. Mr. Marsh takes his readers very much by surprise; for few are aware, we apprehend, that in the course of his wan dering life, and while prosecuting his eminent philological studies, he has made leisure enough to survey the natural sciences with critical exactness, pursue an extended course of inquiry into physical phenomena, note and digest the results of Italian, Spanish, English, French, German, Dutch, and American naturalists, ply every guide and ploughman, every driver and forester, every fisherman and miner, every lumberman and carpenter, for the results which men attain by observing within the narrow circle of their occupation, and weave all into a copious work which subordinates all results to a grand psychological law, the mastery of man's mind over the world it calls its home. The work which we are noticing aspires to and rightly claims a foremost place among the literary productions of America, despite a certain homely flavor and a certain unpretending way which its author has of saying things which are really great and fine. The main thought illustrated is not new, but it is brought out so forcibly, and illustrated by such encyclopedic learning, that it has the power of novelty. Mr. Marsh shows, as many before him have done, that man is now using the organic and inorganic forms of the earth in a manner so subsidiary to the might of his intellect and his will, that such obstacles as mountains and seas, which used to impede him hopelessly, now are his auxiliaries; but he does more than this: he demonstrates the destructive and annihilating sway of man over the world in the past and in the present; and, proceeding from the historic fact that the countries which in the palmy days of the Roman Empire were the granary and the winecellar of the world have been given over by the improvident destructiveness of man to desolation and desert, he enters into a thorough study of the fact, that, no sooner does man recede from the barbaric state than he commences a career of destructiveness, cutting off, in a manner reckless and criminally wasteful, forests, the lives of quadrupeds, birds, insects, and in short every living thing excepting the few domestic animals which follow him and serve him for companionship or for food. Mr. Marsh shows, with more than prophetic insight, with the mathematical logic of facts, that, unless compensations far more general and adequate than have yet been devised are provided, the destructive propensities of civilized man will convert the world into a waste. Some of our readers have paused thoughtfully over that chapter in "Les Misérables 33 which deals so grimly with the sewerage of cities, and details with the faithfulness of an historian the exhausting demands of those conduits which carry untold millions to the sea, and waste that aliment of impoverished soils which not all the science of the age has found it possi ble to restore; but Mr. Marsh, not drawing single pictures with so strong lines, spreads a broader canvas, and compels his reader to equal thoughtfulness. To quote but one instance is enough. We have in America thus far escaped, and as singularly as fortunately, the importation of the wheatmidge which has been the scourge of the grain-fields of Europe: it will, doubtless, some time be a passenger on our Atlantic ships or steamers; it will commence its work; and then man has the task of importing its natural antagonists, of promoting their spread, and so of compensating the evil. The work which we are noticing abundantly shows, that, if man were not in the world, the natural compensations which the Divine Being has introduced would produce perfect harmony in all things; that man, from his first stroke at a tree, his first slaying of a beast or bird, introduces an element of disorder which he can compensate only after civilization has reached a height of which we yet know nothing, and of which our present civilization gives us but the suggestion. To those who may not care to master the philosophy of "Man and Nature," the book presents great attractions in the fund of new and entertaining knowledge given in the text, and yet more largely in the foot-notes. Many have waded through Mr. Buckle's two volumes a second time for the purpose of gleaning his facts and gathering up in the easiest way the latest word in science and literature. Mr. Marsh spreads a homelier table, but one just as varied and hearty. Never in the course of our miscellaneous reading have we met an equal store of fresh facts. As hinted above, they are gathered from every source: the experience of the maple-sugar maker in Vermont is quoted side by side with the testimony of the European scholar. The reader will be amazed that there are so many common things in the world of which he has never heard, and that they have so large and fruitful an influence over the world's progress. If there are striking faults in Mr. Marsh's work, they seem to be these: want of continuity in treatment, and disproportionate development of some subjects in contrast with others. The book is, in fact, too large for a popular treatise, and not large enough for a scientific exposition of all it essays to discuss. It claims to be a popular work; but the elaborate discussion of Forests is far beyond the wishes or needs of any but a scientific reader. The broken, jagged, paragraph style is a drawback to the pleasure of perusing it: the notion seems to impress the author that people will not read anything elaborate, unless it be broken up into labelled paragraphs. It is true of the newspaper: it is not true of the octavo, to which they sit down expecting a different mode of treatment, a broad, discursive style, flowing, redundant, and even eloquent. Yet Mr. Marsh has in some instances transgressed, we think, even in fulness: the great prominence given, for example, to the drainage of Holland is untrue to the general tenor of the book and to the prospective future of the world. It was a great historic deed, when the relations of man to Nature were quite other than what they are to-day; but now that man is master of the sea, regulates the price of bread in London by the price of corn in Illinois, and of broadcloth in Paris by the cost of wool in Australia, the recovery of a few hundred thousand acres from the bottom of the North Sea is a great thing for Holland, but a small thing for the world. Yet we accept this book with grateful thanks to the accomplished author. In the present transition stage from metaphysical to physical studies, it will be eagerly accepted, as showing, not openly nor yet covertly, yet suggestively, the true connection of both. Few books give in quiet, modest fashion so much theology as this, and yet few claim to give so little. Few bear more strongly on the mooted points of Anthropology; few strike so strong a blow at that Development - theory which makes man merely king of the beasts, and superior to the ape and the gorilla only in degree; and yet few proceed in such high argument with less ostentation. This book leaves one great want unfulfilled: to take up the mantle of Ritter and proceed carefully to the study of French, German, Russian, English, Spanish, and Italian history, and indeed all great nations' history, by the light of geography. The problem is stated; it has now only to be wrought out. Perhaps Mr. Marsh, whose acquisitions seem to be boundless, and whose powers unlimited, may live to win fresh laurels on this field.
