¶1The opinion of the Court
¶2The material facts upon which we are to ¿ecj¿e this case are, that the island in dispute between the parties is situated in Pawtucket river, where it is not navigable for ships or boats, and where the tide does not ebb and *283flow ; that the plaintiffs are owners of a tract of land on the east side of the river extending up and down the river beyond the island, and that the defendants are owners of a similar tract on the west side of the river; that the island is not held by any separate grant by either, nor does any other person claim it by virtue of any grant or by possession ; and that both the plaintiffs and the defendants, and those under whom they severally claim and hold their farms on the main land, have occasionally cut trees on the island, but that no agricultural improvement has been made thereon. In a partition of the estate among the heirs of Ebenezer Bucklin, father of the grantor of the plaintiffs, this island was set off to those heirs in 1766, but it does not appear that any possession was taken or hoi den under the partition, except the occasional cutting of wood for forty or fifty years past. It appeared also, that the defendants, or those under whom they claimed, had cut wood on the island for thirty years past at pleasure, without any objection having been made by those who held under Bucklin.
¶3It is obvious from this statement, that neither the plain tiffs nor the defendants had obtained such exclusive possession of the island, or any part of it, as would enable either to maintain trespass against the other, without referring their possession to some title ; and it is equally obvious, that no title appears in either, except what may be derived from their property in the land on either side of the stream or river opposite to the island. And thus we are obliged to consider the rights of those who own the land on the banks of streams or rivers not navigable. And this depends altogether, we think, upon the principles of the common law, there being no statute of this commonwealth, or of the province, nor ordi nonce of the colony, which alters the common law in this respect, except in relation to the fisheries, which having from the beginning been made the subjects of legislative care, must be governed by such rules and regulations as the several legislatures have established.
¶4The common law recognises an important distinction, as to the use of waters and the property of the soil, between rivers or waters navigable, and those which are not navigable. *284The former invariably and exclusively belong to the public, unless acquired from it by individuals under grant or prescription. The latter are held to belong to those whose land borders on the waters ; so that they have the exclusive right of fishing in front of their own land, and have a property in the bed or soil of the river under the water, subject however to an easement or right of passage up and down the stream in boats or other craft for purposes of business, convenience, or pleasure. This is called in the civil law a servitude, which is quite consistent with the right of property. The text book from which this common law principle is most generally deduced, is Sir Matthew Hale’s celebrated treatise Be Jure Maris, published in Hargrave’s Law Tracts, p. 37 ; on recurrence to which it will appear, that Hale referred to the ancient British writer, Bracton, for the foundation of his doctrine, and that he also relied upoo the Roman civil law, as compiled in the Digest in the reign of Justinian. See Dig. lib. 41, tit. 1, De acquirendo Rerum Dominio, leg. 7, 12, 29, 30, 38, 56, 65, and perhaps many others.
¶5This public right in navigable waters and the soil or flats under them, is changed by the colonial ordinance of 1641, which gives to the proprietors of upland bordering on such places, the property of the soil down to the channel, unless it exceed the distance of one hundred rods,
¶6There appears however to be an important difference between the common and the civil law, in regard to the rights of the public and individuals, on this subject. By the former it would seem, that the right of the king or the public, is limited to those places, whether bays, coves, inlets, arms of the sea or rivers, in which the tide ebbs and flows, this being the definition of navigable waters ; whereas by the civil law, *285all rivers properly so called, even above tide waters, provided they are navigable by ships or boats, or perhaps any other floating vehicle, are considered as public property ; and so is the French law, as will appear by the Code Napoleon, liv. 2, tit. 1, c. 3, art. 538, in which are enumerated, among other subjects of public domain, les Jleuves et rivieres navigables on flottables, which last word seems to have been coined to comprehend all streams on which boats, rafts, lumber, or any other species of property may be transported. It is probable that this distinction arose from the difference in magnitude between the rivers on the continent and those on the island, many of the former being navigable much beyond the ebbing and flowing of the sea, and few, if any, of the latter being of consequence for passage or transportation above the tide.
¶7The common law right of public property, restricted as it seems to be except for easement or right of way, may be found very inconvenient in its application to many of the magnificent fresh water rivers of the United States, which are navigable for small vessels and boats much above the flux of the tide, especially by the aid of steam power so rapidly getting into use. And on this account it has been decided by the Supreme Court of Pennsylvania, that the public right to the bed of the river Susquehanna is the same as it is to the ports, harbours, &c., upon the sea ; so that the proprietor of the banks could not extend his claim of property usque ad filum medium aquce, as by the common law he would have the right. Carson v. Blazer, 2 Binney, 475. But the Supreme Court of New York felt themselves bound by the common law, and adjudicated accordingly in the cases reported in 17 Johns. R. 211, and 20 Johns. R. 90.
¶8With respect to the river now in question, however, and the part of it where the island in controversy is found, which is above tide waters, and which we have a right to presume is not navigable even for boats, we think it clear that the common law doctrine applies, giving to the proprietors of the hanks the property of the bed of the river usque ad jilum medium aquce
¶9*287The question then arises, to whom belongs an island formed oy a division of the waters of a river, where but for the island the borderers on the river would meet each other in the middle of the river; and this question must be settled by analogy to cases of a similar nature, which, though they may have arisen in other countries under the jurisdiction of the civil law, have nevertheless been adopted- by the common law as fairly coming within its general principles.
¶10The doctrine of alluvion and its consequences seems to be very clearly settled. That which is formed by gradual accretion, belongs to the owner of the soil to which it adheres.
¶11According to these principles therefore, this island belongs in severalty to these borderers on each side of the stream, if their lands on the main are coextensive with the island ; if not, then the owners of the next adjoining lots will have a right to claim a portion of the island conformable to their lines. And this settles the present case in favor of the plaintiffs, for it appears that the bridge removed extended from their land to the island; the removal of it was therefore a trespass. But in regard to the trees cut down, it is not shown on which part of the island they stood ; so that whether they belonged to the plaintiffs, or to the defendants, does not appear.
¶12The verdict, being for the defendants, must be set aside and a new trial granted.
¶13 Morton J. did not sit in this cause.

¶15 See Canal Commissioners and Canal Appraisers v. People, 5 Wendell, 423; where it is held by Chancellor Walworth, that the principle of the common law extending grants usque ad filum aquce is not sufficiently broad to embrace the fresh water lakes in New York. As to them the local law of that State assigns the shores down to ordinary low water mark to the riparian owners, and the bed of the lakes, with the land therein to the public.
¶16In the same case it was held by Senator Beardsley, that this principle of the common law, extending grants usque ad filum aquce¡ does not apply to the large fresh water rivers of New York, or, at all events, a patent bounded on *286a river navigable above tide water passes no interest to the patentee in the bed of the river as against the State.
¶17But see People v. Canal Appraisers, 13 Wendell, 355, where the applica bility of this common law principle to such rivers is considered as no longei subject to a question.
¶18In this last case it was also decided, that where the stream is navigable foi boats or rafts, the public have a right to use it for these purposes, and the rights of the adjoining proprietors are subject to the public easement. But the State cannot divert the water of the stream or interfere with it in any other manner, which will render it less useful to the proprietors of the adjoin ing shores. See also Berry v. Carle, 3 Greenl. 269; 3 Kent’s Comm (3d ed. 429.
