immediate connection. It may be set back a short distance from the revetted bank; but it is, in effect, the requisite parapet. The flood river and the low river cannot be brought into register, and compelled to unite in the excavation of a single permanent channel, without a complete control of all the stages; and even the abnormal rise must be provided against, because this would endanger the levee, and once in force behind the works of revetment would tear them also away.

Under the general principle that the local slope of a river is the result and measure of the resistance of its bed, it is evident that a narrow and deep stream should have less slope, because it has less frictional surface in proportion to capacity; i.e., less perimeter in proportion to area of cross section. The ultimate effect of levees and revetments confining the floods and bringing all the stages of the river into register is to deepen the channel and let down the slope. The first effect of the levees is to raise the surface; but this, by inducing greater velocity of flow, inevitably causes an enlargement of section, and if this enlargement is prevented from being made at the expense of the banks, the bottom must give way and the form of the waterway be so improved as to admit this flow with less rise. The actual experience with levees upon the Mississippi River, with no attempt to hold the banks, has been favorable, and no one can doubt, upon the evidence furnished in the reports of the commission, that if the earliest levees had been accompanied by revetment of banks, and made complete, we should have to-day a river navigable at low water, and an adjacent country safe from inundation.

Of course it would be illogical to conclude that the constrained river can ever lower its flood slope so as to make levees unnecessary, but it is believed that, by this lateral constraint, the river as a conduit may be so improved in form that even those rare floods which result from the coincident rising of many tributaries will find vent without destroying levees of ordinary height. That the actual capacity of a channel through alluvium depends upon its service during floods has been often shown, but this capacity does not include anomalous, but recurrent, floods.

It is hardly worth while to consider the projects for relieving the Mississippi River floods by creating new outlets, since these sensational propositions have commended themselves only to unthinking minds, and have no support among engineers. Were the river bed cast-iron, a resort to openings for surplus waters might be a necessity; but as the bottom is yielding, and the best form of outlet is a single deep channel, as realizing the least ratio of perimeter to area of cross section, there could not well be a more unphilosophical method of treatment than the multiplication of avenues of escape.

In the foregoing statement the attempt has been made to condense in as limited a space as the importance of the subject would permit, the general elements of the problem, and the general features of the proposed method of improvement which has been adopted by the Mississippi River Commission.

The writer cannot help feeling that it is somewhat presumptuous on his part to attempt to present the facts relating to an enterprise which calls for the highest scientific skill; but it is a matter which interests every citizen of the United States, and is one of the methods of reconstruction which ought to be approved. It is a war claim which implies no private gain, and no compensation except for one of the cases of destruction incident to war, which may well be repaired by the people of the whole country.

APPENDIX C

RECEPTION OF CAPTAIN BASIL HALL'S BOOK IN THE UNITED STATES

HAVING now arrived nearly at the end of our travels, I am induced, ere I conclude, again to mention what I consider as one of the most remarkable traits in the national character of the Americans; namely, their exquisite sensitiveness and soreness respecting everything said or written concerning them. Of this, perhaps, the most remarkable example I can give is the effect produced on nearly every class of readers by the appearance of Captain Basil Hall's 'Travels in North America.' In fact, it was a sort of moral earthquake, and the vibration it occasioned through the nerves of the republic, from one corner of the Union to the other, was by no means over when I left the country in July 1831, a couple of years after the shock.

I was in Cincinnati when these volumes came out, but it was not till July 1830, that I procured a copy of them. One bookseller to whom I applied told me that he had had a few copies before he understood the nature of the work, but that, after becoming acquainted with it, nothing should induce him to sell another. Other persons of his profession must, however, have been less scrupulous; for the book was read in city, town, village, and hamlet, steamboat, and stage-coach, and a sort of war-whoop was sent forth perfectly unprecedented in my recollection upon any occasion whatever.

An ardent desire for approbation, and a delicate sensitiveness under censure, have always, I believe, been considered as amiable traits of character; but the condition into which the appearance of Captain Hall's work threw the republic shows plainly that these feelings, if carried to excess, produce a weakness which amounts to imbecility.

It was perfectly astonishing to hear men who, on other subjects, were of some judgment, utter their opinions upon this. I never heard of any instance in which the commonsense generally found in national criticism was so overthrown by passion. I do not speak of the want of justice, and of fair and liberal interpretation: these, perhaps, were hardly to be expected. Other nations have been called thin-skinned, but the citizens of the Union have, apparently, no skins at all; they wince if a breeze blows over them, unless it be tempered with adulation. It was not, therefore, very surprising that the acute and forcible observations of a traveler they knew would be listened to should be received testily. The extraordinary features of the business were, first, the excess of the rage into which they lashed themselves; and, secondly, the puerility of the inventions by which they attempted to account for the severity with which they fancied they had been treated.

Not content with declaring that the volumes contained no word of truth, from beginning to end (which is an assertion I heard made very nearly as often as they were mentioned), the whole country set to work to discover the causes why Captain Hall had visited the United States, and why he had published his book.

I have heard it said with as much precision and gravity as if the statement had been conveyed by an official report, that Captain Hall had been sent out by the British Government expressly for the purpose of checking the growing admiration of England for the Government of the United States,that it was by a commission from the treasury he had come, and that it was only in obedience to orders that he had found anything to object to.

I do not give this as the gossip of a coterie; I am persuaded that it is the belief of a very considerable portion of the country. So deep is the conviction of this singular people that they cannot be seen without being admired, that they will not admit the possibility that any one should honestly and sincerely find aught to disapprove in them or their country.

The American Reviews are, many of them, I believe, well known in England; I need not, therefore, quote them here, but I sometimes wondered that they, none of them, ever thought of translating Obadiah's curse into classic American; if they had done so, on placing (he, Basil Hall) between brackets, instead of (he, Obadiah) it would have saved them a world of trouble.

I can hardly describe the curiosity with which I sat down at length to peruse these tremendous volumes; still less can I do justice to my surprise at their contents. To say that I found not one exaggerated statement throughout the work is by no means saying enough. It is impossible for any one who knows the country not to see that Captain Hall earnestly sought out things to admire and commend. When he praises, it is with evident pleasure; and when he finds fault, it is with evident reluctance and restraint, excepting where motives purely patriotic urge him to state roundly what it is for the benefit of his country should be known.

In fact, Captain Hall saw the country to the greatest possible advantage. Furnished, of course, with letters of introduction to the most distinguished individuals, and with the still more influential recommendation of his own reputation, he was received in full drawing-room style and state from one end of the Union to the other. He saw the country in full dress, and had little or no opportunity of judging of it unhouselled, unanointed, unannealed, with all its imperfections on its head, as I and my family too often had.

Captain Hall had certainly excellent opportunities of making himself acquainted with the form of the government and the laws; and of receiving, moreover, the best oral commentary upon them, in conversation with the most distinguished citizens. Of these opportunities he made excellent use; nothing important met his eye which did not receive that sort of analytical attention which an experienced and philosophical traveler alone can give. This has made his volumes highly interesting and valuable; but I am deeply persuaded, that were a man of equal penetration to visit the United States with no other means of becoming acquainted with the national character than the ordinary working-day intercourse of life, he would conceive an infinitely lower idea of the moral atmosphere of the country than Captain Hall appears to have done; and the internal conviction on my mind is strong, that if Captain Hall had not placed a firm restraint on himself, he must have given expression to far deeper indignation than any he has uttered against many points in the American character, with which he shows from other circumstances that he was well acquainted. His rule appears to have been to state just so much of the truth as would leave on the mind of his readers a correct impression, at the least cost of pain to the sensitive folks he was writing about. He states his own opinions and feelings, and leaves it to be inferred that he has good grounds for adopting them; but he spares the Americans the bitterness which a detail of the circumstances would have produced.

If any one chooses to say that some wicked antipathy to twelve millions of strangers is the origin of my opinion, I must bear it; and were the question one of mere idle speculation, I certainly would not court the abuse I must meet for stating it. But it is not so.

. . . . . . .

The candor which he expresses, and evidently feels, they mistake for irony, or totally distrust; his unwillingness to give pain to persons from whom he has received kindness, they scornfully reject as affectation, and although they must know right well, in their own secret hearts, how infinitely more they lay at his mercy than he has chosen to betray; they pretend, even to themselves, that he has exaggerated the bad points of their character and institutions; whereas, the truth is, that he has let them off with a degree of tenderness which may be
