In Gibbons _v._ Ogden[839] the Court, speaking by Chief Justice Marshall, held that New York legislation which excluded from the navigable waters of that State steam vessels enrolled and licensed under an act of Congress to engage in the coasting trade was in conflict with the act of Congress and hence void. In Willson _v._ Blackbird Creek and Marsh Co.[840] the same Court held that in the absence of an act of Congress, "the object of which was to control State legislation over those small navigable creeks into which the tide flows," the State of Delaware was entitled to incorporate a company vested with the right to erect a dam across such a creek. From these two cases the Court in Cooley _v._ the Board of Wardens,[841] decided in 1851, extracted the rule that in the absence of conflicting legislation by Congress States were entitled to enact legislation adapted to the local needs of interstate and foreign commerce, that a pilotage law was of this description, and was, accordingly, constitutionally applicable until Congress acted to the contrary to vessels engaged in the coasting trade. In the main, these three holdings have controlled the decision of cases under the above and the following caption, there being generally no applicable act of Congress involved. But the power which the rule attributed to the States, they must use "reasonably," something they have not always done in the judgment of the Court. Thus an Alabama statute which required that owners of vessels using the public waters of the enacting State be enrolled, pay fees, file statements as to ownership, etc., was held to be inapplicable to vessels licensed under the act of Congress to engage in the coasting trade;[842] as was also a Louisiana statute ordering masters and wardens of the port of Orleans to survey the hatches of all vessels arriving there and to enact a fee for so doing.[843] "The unreason and the oppressive character of the act" was held to take it out of the class of local legislation protected by the rule of the Cooley case.[844] Likewise, while control by a State of navigable waters wholly within its borders has been often asserted to be complete in the absence of regulation by Congress,[845] Congress may assume control at any time;[846] and when such waters connect with other similar waters "so as to form a waterway to other States or foreign nations, [they] cannot be obstructed or impeded so as to impair, defeat, or place any burden upon a right to their navigation granted by Congress."[847]
