of eminent domain, and allows just compensation either in benefits or money, or both, according to the circumstances. So the states along the Mississippi may levee the river for public protection, but it seems scarcely consistent with just rights of property that they should do this by general law at the expense of the owners of private property.
A sudden breach and instant danger might change the rule. Mr. Cooley, in his Constitutional Limitations, states the case as a general principle, on the authority of Crowley v. Copley, but without any reference to the precise question decided, or the ground of the exercise of the power. It would seem probable he attributed it to the exercise of the power of eminent domain, as he begins the next sentence with these words: “ And the right of eminent domain is sometimes exercised in order to drain considerable tracts of country.” But if it be this power, the condition of its exercise would certainly be compensation in some form, benefits it might be. A better view of the relations of the owners of land on the Mississippi, it seems to me, is that of Chief Justice Shaw, in the Commonwealth v. Alger, 7 Cushing 86-7, when discussing the power of the state to prevent an owner of tide-water land from removing a natural embankment, to the prejudice of the public. “Principles,” he says, “ are tested by taking extreme cases. Take the case of the river Mississippi, where large tracts of country, with cities and villages, depend for their protection upon the natural river bank, which is private property. Perhaps, under such circumstances, it might not be too much to say, not only that the owner cannot do any positive act' toward removing the embankment, but that he may properly be held responsible for the permissive waste of it by negligence and inattention.” Here is no intimation of a liability to throw up new banks, but only a moderate expression of opinion of liability for waste. A natural marsh, between high- and low-water lines, has no such features as the Mississippi lands, and no such great public calamity to guard against. No one is interested but the owner of like marsh lands, having a like qualified title, subject to a like natural flow of the river. So much may safely be said of the original or natural state of the property. But where the state has banked out the water, and the owner is left in possession of the improvement made by the state, under her sovereign authority and at her own expense, it seems to me he stands in a new and different relation. The state having, by her own-authority, taken the land between high- and low-water lines out of the public use, has, in effect, appropriated it to the use of the owner of the qualified title, and in effect conferred upon him an absolute .title. She has thus benefited him, and it is but just that the duty of repair should now devolve upon him. To this extent we may, I think, conclude that the Act of March 25th 1848, under which this proceeding took place, is constitutional: Pamph.
