delivered the opinion of the court,
The defendants were incorporated under the laws of NeAV York, and by divers statutes of this state, are vested Avith certain public franchises. Eor the purposes of the grant the dam across the Dela-Avare river was built about fifty years ago, and the right to maintain it is conceded. In the Act of 1825, Pamph. L. 142, is a provision *37“That the said company shall not erect any works, or make any improvement, connected with the Delaware river, unless the same shall be so constructed as to leave the channel of said river as safe and as convenient for the descent of rafts as it now is.” The plaintiff complains that the river is not as safe and convenient for navigation as before the erection of the dam. Unquestionably this is so. A dam in a stream is an impediment and in some degree renders its navigation less safe and convenient. A literal construction of this provision makes it impossible to build and maintain the dam, and the conceded right vanishes. The statutes of this state, recognising those of New York, and in connection therewith, conferring the power to construct a great public highway, are nugatory under a strict construction of the section providing for safe and convenient navigation of the river. This was not the legislative intent. It could not have been intended to grant a franchise to build a public highway, in connection with one in a sister state, and so clog it that the work could never be executed.
Various statutes, from time to time, have been enacted authorizing public improvements, some of which would obstruct or impede the navigation of rivers, and others the use of streets and roads, which contained provisions forbidding such obstructions and impediments. The courts have uniformly held that these provisions should be liberally construed, so as not to destroy the grant. For instance, the act of incorporation of the Monongahela Bridge Company contained a declaration that nothing therein contained should authorize the erection of a bridge over the Monongahela river “in such manner as to injure, stop, or interrupt the navigation of the said river, by boats, rafts or other vessels.” It was held that the proviso was not intended to prevent the erection of piers in the bed of the river, yet piers in the bed of a navigable stream inevitably endanger navigation and render it more difficult. They do not necessarily “injure, stop or interrupt the navigation” in the sense in which these words were used by the legislature. A strict literal meaning was not intended, and in the very nature of things, it never could have been. When the purpose of the franchise is the performance of a public act, the grant is to be so interpreted as to enable the act to be done. The extension of one highway over another is a public act, and not less so because of the power to exact tolls: Monongahela Bridge Co. v. Kirk, 10 Wright 112. The charter of the Erie and North East Railroad Company had a provision that “ The said railroad shall be so constructed as not to impede or obstruct the free use of any public road, street, lane or bridge nowr laid out, opened or built.” “ These words taken literally and in their strongest sense would prevent the railroad from being made on the streets at all. 'But we follow authority in saying they are not to be so interpreted. The defendants have a right to use a street if they take care to obstruct it as little as the nature and char*38acter of their improvement mil permit, if they create no material or unnecessary impediment — no obstruction which could be avoided by any reasonable expenditure of money or labor. They cannot occupy the whole of a street and drive the public away from it altogether. But any street which is wide enough for the railroad and public both may be used on the terms mentioned.” Per Black, C. J., Commonwealth v. E. & N. E. Railroad Co., 3 Casey 365.
It is no departure from the current of decisions, but in its direct line, to hold that the defendants can enjoy their franchise, can lawfully construct and maintain their dam, taking care to obstruct the channel as little as the nature and character of the improvement will permit, and leaving it as safe and convenient for the navigation of rafts as could be by any reasonable expenditure of money and labor. Their franchise is for the construction of one highway over another. The whole community are interested in both. Private charters are strictly interpreted. In them what is not expressed or necessarily implied, is not granted, and what is doubtful is resolved in favor of the sovereign. But when the sovereign grants a public franchise over a highway, a clause relative ' to the use of said highway will not be so construed as to defeat the grant.
The plaintiff does not claim merely for consequential damages, resulting solely from the construction of the dam. If he did, the defendants’ answer would be found in Clark v. Birmingham and Pitts. Bridge Co., 5 Wright 147, and Monongahela Bridge Co. v. Kirk, supra.
He claims further for an immediate injury, consequent upon the defendants’ negligence, in that they “built and left the said dam in and across said highway, in a dangerous, insecure and impassable state and condition.” His averment implies much more than such obstruction as was necessary for the purposes of the franchise, and, if established, and there was no contributory negligence, his right to recover is clear. If he adduced sufficient proof of such negligence, it should have been submitted to the jury.
The evidence of the broken and damaged condition of the rafts, before reaching the dam, will not be specially noted, though that would have been important as tending to show contributory negligence, had the case been submitted.
Surrine and Lakin were steersmen on the rafts. Both had had long experience on that river, and neither ever had bad luck or stove a raft on that dam before. They agree that the water in the schute was rougher than usual, and that the water in the roll was rougher than in the schute. The injury was done in the roll. A raft ahead of them was stove to pieces at same place. Surrine says, “I think that dam is about as bad as any place we have on that river.” Lakin says, “ It was a fair freshet. The slash-boards were on the dam. They caused a tendency to draw the rafts to Jersey.” “ I *39should not call the dam very safe.” “ Are not the slash-boards always there, except when the water is high, on the Jersey side of the crib ?” “ I cannot say they wasn’t.” “And are they not kept there to throw water in the channel and help you over the dam ? wouldn’t that be the effect to throw water through the rafting channel?” “Yes, sir.” Curtis, who was on the raft with Surrine, says, “ I laid it to the slash-boards, which made the surges of the water, and that seemed heavy. I think the damage was done by the dam; I don’t know what else could have done it. If there had not been any dam there it could not have done any injury. There is always a roll right there in a freshet.” With this evidence to make out the charge of negligence, the plaintiff rested. There is no pretence that the defendants’ witnesses added to its strength. The plaintiff’s witnesses had been in his employ on the rafts and had ability to discover anything unusual, done or omitted by defendants, to cause the extraordinary roughness of the water. Yet careful counsel failed to point to an expression tending to show an unusual condition of the dam in reference to the stage of the water. One Avitness laid the unusual roll to the slash-boards, but neither he nor any other said it Avas uncommon for the slash-boards to be there. He Avas, hoAA'ever, correct in saying, “ if the dam had not been there it could not have done any injury.” But it was by no means sufficient to establish negligence to connect the injury Avith the dam.
The dam had-been rightfully there for many years. The Commonwealth has made no complaint of abuse of the grant. In 1830 she exonerated the defendants from building the river lock in the dam until they shall be required by the legislature: Pamph. L. 407. There is no evidence of change in the dam since that date. Neither court nor jury can say a lock should have been constructed after the Commonwealth has said otherwise. Negligence Avill not be presumed. When the plaintiff avers that defendants have constructed and maintained'their dam in violation of their statutory rights, and in such'manner as not to be the least obstructive to the navigation of the river, consistent with the use of the dam for the purposes of their franchise, and by some negligent act have caused him immediate injury, the burden is on him to prove his averments. The mere fact that the rafts Avere injured by the dam is hot enough. It falls as far short of sufficient -proof as does the fact alone of the killing a horse by a railway train when crossing a street, fall short of shoAving negligence in the raihvay company. A spark, a scintilla of evidence of negligence by the defendants is here, and no more. The learned judge Avas right in his conclusion that the evidence Avas insufficient to Avarrant a finding that the defendants were guilty of negligence.
Judgment affirmed.
