space is not a part of the bank.' Now, substituting for the heats of the summer season' which is circumstance, and immaterial, the term 'low water,' which is the substance of the case, nothing can more perfectly describe the beach or batture, nor collated with the other authorities, make a more consistent and rational provision. The bank ends at that line on the levée to which the river rises at its full tide: and altho' the batture or beach next below that line is uncovered by the river, when reduced to its low tide, yet that batture or beach does not therefore become a part of the bank, but remains a part of the bed of the river,' for says Theophilus 'even in low water [et æstate] we bound the bank at the line of high water.' Inst. 2. 1. 3. The bank being the extima alvei, the border of the bed, within which bed the river flows when in its fullest state naturally, that is to say, not when imbribus, vel quâ aliâ ratione, ad tempus, excrevit,' not when 'temporarily overflowed by extraordinary rains, &c.' Dig. 43. 12. 5. but quando mas crece, sin salir de su madre, en qualquiera tiempo del año,' when in its full height, without leaving its bed, to whatsoever season of the year the period of full height may belong.' This is unquestionably the meaning of all the authorities taken together, and explaining one another.

From these authorities, then, the conclusion is most rigorously exact, that all is river, or river's bed, which is contained between the two banks, and the high water line on them; and all is bank which embraces the waters in their ordinary full tide.

Agreeably to this has been the constant practice and extent of grants of lands on the Missisipi. Charles Trudeau swears [Liv. 57.] that during 28 years that he has performed the functions of Surveyor General of this province, it has always been in his knowledge, that the grants of lands on the borders of the Missisipi, have their fronts on the edge of the river itself, and when its waters are at their greatest height.' And Laveau Trudeau [Liv. 58.] that the concession to the Jesuits, he believes, was like all the others, that is, from the river at its greatest height.'

Thus we see what the law is; that it has been perfectly understood in the territory, and has been constantly practiced on, and consequently that neither the grant to the Jesuits, nor to Bertrand Gravier, could have included the beach or batture.

It will perhaps be objected that, establishing the commencement of the bank at high water mark, leaves in fact no bank at all, as the high water regularly overflows the natural bank or brim of the channel. it be a new phenomenon to see a river without banks sufficient to contain its waters at their full tide? The Missisipi is certainly a river of a character marked by strong features. It will be very practicable, by exaggerating these, to draw a line of separation between this and the mass of the rivers of our country, to consider it as sui generis, not subject to the laws which govern other rivers, but needing a system of law for itself. And until this system can be prepared it may be abandoned to speculations of death and devastation like the present. But will this be the object of the sound judge or legislator? it is certainly for the good of the whole nation to assimilate as much as possible all its parts, to strengthen their analogies, obliterate the traits of difference, and to deal law and justice to all by the same rule and same measure. The bayous of all that territory and of the country thence to Florida Point are without banks to contain their full tides. The Missisipi is in the like state as far as Bâton Rouge, where competent banks first rise out of the waters, and continue with intervals of depression to its upper parts. Many of the rivers of our maritime states are under circumstances resembling these. The channel which nature has hallowed for them is not yet deep enough, or the depositions of earth on the adjacent grounds not yet sufficiently accumulated, to raise them entirely clear of the flood tides. Extensive bodies of lands, still marshy therefore, are covered by them at every tide. In some of these cases, the hand of man, regulated by laws which restrain obstructions to navigation and injury to others, has aided and expedited the operations of nature, by raising the bank which she had begun, and redeeming the lands from the dominion of

the waters. The same thing has been done on the Missisipi. An artificial bank of 3, 4, or 5 feet has been raised on the natural one, has made that sufficient to contain its full waters, and to protect a fertile and extensive country from its ravages. These are become the real banks of the river, on which the laws operate as if the whole was natural. The Nile, like the Missisipi, has natural banks, not competent in every part to the conveyance of its waters. In these parts artificial banks are, in like manner, raised, through which and the natural bayous and artificial canals the inundation, when at a given† height, is admitted; this being indispensable to fertilize the lands in a country where it never rains. And these banks of the Nile, nat

ural and artificial, are recognized as such by the Roman *51 law, as appears in a passage of the Digest before cited, declaring that its banks, tho' inundated periodically, are not thereby changed. Nor are those of our rivers when temporarily overflowed by rains, or other causes. Wherever therefore the banks of the Missisipi have no high water line, the objection is of no consequence, because the lands there are not as yet reclaimed or inhabited; and wherever they are reclaimed, the objection is not true; for there a high water line exists to separate the private from public right.‡

This part of our subject merits fuller development. That the periodical overflowings of some rivers do not differ from the accidental overflowings of others, in any circumstance which should affect the law of the high water line, in the one more than in the other, will be rendered more evident by taking a comparative view of them. To begin with ordinary rivers. 1. These have along their greater part, and some of them through their whole course, natural banks adequate to the confinement of their waters, in the high water season, except in cases of accidental inundation. Here, then, the Roman authorities tell us the inundation does not change the bank, nor the landmark on it. 2. Along other parts, where the natural bank was not high enough to contain the river in its season of steady high water, the hand of man has raised an artificial bank on the natural one, which effects this purpose, with the exception, as before, of accidental inundations, where such happen. This artificial bank performs all the func

tions of the natural, and is placed under the same law. 3. In other parts of them, the natural banks are still not high enough to contain the high tides, nor have they yet been made so by the hand of man. Here then the law cannot operate, because the local peculiarities, as yet, exclude the case from its provisions. The ground so covered by inundation, has been, or may yet be, public property. But the legislator, instead of holding it as the bed of the river, grants it to individuals as far as to the natural or incipient bank, that they, by completing the bank, may reclaim the land, for their own and the public benefit, and, this done, the law comes into action on it. Much of this reclaimed, and unreclaimed land exists in all these states.

I proceed next to rivers of particular character. Of which among those analogous to the Missisipi, the Nile is best known to us, and shall be described. That river entering Upper Egypt at its Cataracts, flows through a valley of 20 or 30 miles wide, and of 450 miles in length, bounded on both sides by a continued ridge of mountains. Through most of this course, its natural banks are sufficient to contain its waters in time of flood, till they rise to that height, at which, by their law, they are to be drawn off. In low parts, where the natural banks are not sufficient, they have been raised by hand to the necessary height. In addition also to the natural bayous, like those of the Missisipi, they have opened numerous canals, leading off at right angles from the river towards the mountains, and sufficient to draw off the greatest part of the current passing down the river. These, in ordinary times, are closed by artificial banks raised to the level of the natural ones. When the flood is at a height sufficient for irrigating and fertilizing the fields, which by the Nilometer is at 16 cubits above the bed of the the river, these artificial banks are cut, and the waters let in. The plain declining gently from the banks of the river, (which, like those of the Missisipi, are the highest ground,) towards the mountains, the waters are there stopped, as by a dam, and continue to rise, and diffuse themselves till they reflow nearly to the bank of the river. If the rise ceases there, the waters remain stagnant, and deposit a fertilizing mud, over the whole surface. But if uncommon rains above occasion a continuance of the rise till all the waters meet over the summits of the banks, then the motion of that in the river is communicated to the stagnant water on the plains, a general current takes place, and instead of a depositum left, the former soil is swept away to the ocean, and famine ensues that year. This, the traveller Bruce informs us, had happened three times within the 30 years preceding his being in that country. When the waters have withdrawn, and the river is returned into its natural bed, the banks are repaired in readiness to restrain the floods of the ensuing year. Such is the case in Upper Egypt. When the river enters Lower Egypt, it parts into two principal branches, the Pelusian

and Canopic, which diverge and reach the Mediterranean at about 200 miles apart, including between them the triangle called the Delta. Besides these, there are, within the Delta, three natural Bayous, and two canals, dry at low water, which make up the famed seven mouths of the Nile. The mountains diverge so as do the main branches of the river, the eastern going off to the isthmus of Suez, and the Western to the sea near Alexandria. The waters lessened by depletion, and spreading over a widening plain are reduced, by the time they reach the base of the triangle at the sea, to one or two cubits depth. Banks, therefore, of 3 to 4 feet high, are sufficient to protect the country until here also they open the bayous and canals which intersect the triangle. Here then the case recurs of a river whose natural banks are partly competent to contain its high waters in common floods, and are partly made so by the hand of man; so as to furnish an ordinary high water line In extraordinary floods it overflows these banks, and in ordinary ones is let through them. Yet these inundations as the Digest declares, do not change the banks. 'Nemo dixit Nilum ripas suas mutare,' &c. But when the river retires within its natural bed, the banks are again repaired: 'cum ad perpetuam sui mensuram redierit, ripa alvei ejus muniendæ sunt,' ib. [See 2. Herodot. 6-19. Strabo 788. 1 Univ. Hist. 391-413. 1 Maillet Description de l'Egypte 14-121. 1 De la Croix 338. Encyclop. Meth. Geographie. Nil. 1 Savary 3-14. 2 Savary 185-275. 1 Volney 34-48. 4 Bruce 364—407.] 1. The Upper Missisipi, like the Upper Nile, has competent natural banks through probably three fourths of its whole course. There then the Roman law is applicable in its very letter. 2. For about 400 miles more, the natural banks have been aided by artificial ones, on both sides, so as to contain all the waters of the flumen plenissimum: and the inhabitants there have no occasion as those of the Nile, to open their banks for the purpose either of fertilizing, or irrigating the lands. Here then there is still less reason, than in the case of the Nile, to say that the Missisipi has changed its bank.' 3. On the lower parts of the Missisipi and some of its middle portion, especially on the Western side, artificial banks have not yet been made, and the country is regularly inundated, as it is on those parts of our Atlantic rivers not yet embanked. But our increasing population will continue to extend these banks of our Atlantic rivers; and, for this purpose, our governments grant the lands to individuals. And the same, we know, is done on the Missisipi. The Cyprieres adjacent to New-Orleans, for example, though covered with the refluent water from the lake, we know have been granted to individuals, and will, with the rest of the drowned lands, be reclaimed in time, as all lower Egypt has been.

Thus then we find the laws of the Tyber and Nile transferred and applied to the Missisipi with perfect accordance, and that all rivers may be governed by
