Before proceeding to examine the validity of those several pleas, it becomes necessary to decide the question raised by the defendants’counsel, as to the substance of the declaration ; for it is an established rule, that on a demurrer to a plea, if the prior pleading be defective in substance, judgment must be given against the party pleading it. It is insisted that this declaration, though in form is in case, is in substance a declaration in tresspass, or that the injury charged to be done, is a trespass vi et armis,or that it contains a complaint both in case and trespass, being an illegal joinder of actions; and therefore that judgment should be rendered against the plaintiffs, on this demurrer. The injury complained of, is that the defendants constructed a rail road parallel and near to the plaintiffs’road, and crossing it in six different places, and used it with engines, so that it became dangerous for travellers to pass and repass on the plaintiffs’ road, whereby the plaintiffs have been disturbed in their franchise. The complaint clearly set forth, is that the defendants, by the use of engines along and over the turnpike road, hindered and disturbed the plaintiffs in their franchise, and in the receipt of their accustomed tolls. For a disturbance of a franchise, case is clearly the proper form of remedy. Here the injury is consequential and not direct, it is hindering travellers from passing on the road; by means of the fire and smoke, noise and unusual appearances of the defendants’ machines, used adjacentto, as well as upon the road; whereby the plaintiffs have lost their accustomed tolls ; and although in describing the mode in which this injury has been effected, the plaintiffs have charged among other things, an entry on their lands, yet such entry is not distinctly alledged as the ground of complaint. But suppose the injury arose in part from the entry upon the plaintiffs’ lands, and in part from the use of the engines along the line, and adjacent to their lands, the whole being one continued act of the defendants,and for thatcausecouldbeesteemedbothdirectand conse*318quential, the plaintiffs might elect to bring case or trespass. McAllister v. Hammond, 6 Cowen’s R. 342, and in describing the act complained of, could not avoid stating the entry. The plaintiffs too, may waive the immediate, and go for the consequential injury. The declaration, therefore, is in my opinion, well drawn and not defective.
The counsel in'support of demurrer, contend that these pleas are defective in that they contain no averment that the defendants-have acquired title to the plaintiffs’ lands-, by agreement or assessment, or in any other mode provided by their act of incorporation.
It is true that, these pleas contain no such distinct averment, nor is it necessary that they should. So far as regards the complaint, it being in truth for consequential damages, not for the trespass by entry, it is no matter, whether the defendants had title or not. But the plcas.do aver that by virtue and pursuant to their act of incorporation, they made their survey, located and constructed their road, where by law they might construct it, anil that pursuant to the authority in them vested by said act, they used the engines upon their said road, as by said law they had a right to do. This is substantially an averment that they had done all things required by their charter, and that so far astiieir charter warranted, they were fully authorized todotheacts.complained of. The exception, therefore,to the pleas in this respect, is not well taken. But admitting that the pleas arc correct and well pleaded, so far as regards form, it is insisted that they constitute no defence or justification for the acts complained of — - and this presents, in fact, the only true questions involved in tliecase.
Upon this' point, it is insisted by the plaintiffs,
1st. That a legislative authority to construct a rail road,, does not include an authority to use a locomotive engine upon it.
2d. That a locomotive engine used upon, or adjacent to a public highway, is a nuisance — and .
Sd. That if the use of such engines is authorized, either by the expressed grant of the legislature, to the defendants, or by a fair legal construction of their charter, still that the defendants cannot set up such authority by way of defence or justification *319to an injury to another, charged and proved as the consequence of such use,
I will consider these points in the order in which they are presented.
1st. The legislature of New Jersey, by an act passed the 4th of February, 1830, authorized the laying out and construction of a rail road from the Delaware river to Raritan bay, and incorporated the defendants into a company to effect the object designed, and invested them with power to determine the description of carriages to be used upon said road, the weight to bs carried, the times of starting, and rate of travelling thereon. And imposed a penalty on any person who should wilfully obstruct said road, or injure or destroy the carriages or machines of the company; and also made it the duty of the company to construct and keep in repair, proper passages where any public or other road should cross the same. Here is a clear legislative authority to construct a rail road, to own, and by necessary implication to use machines and engines upon it, and to crass or intersect private or other roads, and investing them with ail rights, powers and privileges necessary to perfect an expeditious and complete line of communication between Philadelphia and New York, All grants are to be construed according to the ordinary and natural sense of the terms used.
When tisis charter was granted, although rail roads were of recent introduction here,yet their character and the mode of using them, were well known to the legislature, and the authority to make and use them, includes the authority to use them in such mode, by such carriages and machines as were ordinarily used upon such roads. This would be a fair and legal construction of the charter of the defendants, and their powers under it, even if the act had made no reference to machines, but the use of that term, more clearly vindicates that the legislature contemplated the use of steam engines upon the road.
I am of opinion therefore, that the grant to the defendants to construct and use a rail way, is also an authority to them to use locomotive engines upon it.
2d. It is insisted that the use of a steam engine upon or rear a public highway, is a nuisance. If I am right in the position that the charter of the defendants contemplated and as;*320thorized the use of steam engines on their road, then such use can never be construed a public nuisance; for that which is authorized by law, is in itself lawful, and can never bo the subject of indictment. The use of steam, however, though warranted by law, on rail roads, may nevertheless work a private injury, and thereby become a private nuisance, for which, a remedy maybe had by the party injured by action.
This leads me to the consideration of the 3d point taken by the pltfFs. to wit: that even if the defendants are by law authorized to usesteampowcron their road,it must be done in such way as not to interfere with or impair the rights of the plaintiffs or any one else and if they dp so interfere with or disturb the rights of others, their charter constitutes no defence or justification, and that these pleas, therefore, are defective and no answer to the plaintiffs’ complaint.
This court has decided in the case of Johnsons a. Sinnickson, 2 Harrison. 129, that an injury to private property, by an individual acting under legislative authority, cannot be justified unless the act causing the injury, was done by him as the agent or in behalf of .the government, and to effect an object of public interest. To apply this principle to the present case. The defendants in the construction and use of their road, are not acting .in (lie capacity of public agents, but as an incorporation pursuing their own interests in the mode warranted by their charter, and if in the lawful exercise of this power, they inflict an injury upon the private rights of others, they must respond in damages for such injury. Such injury, however, must be the natural and direct result of the act itself [as in the case referred to, where the overflowing of the plaintiff’s land was the direct and natural consequence of the erection of the dam by the defendants] and not a •consequence which results from the fears, prejudices, passions or •caprices of the public; for in the former case, the damages may be ascertained by clear and precise evidence, whilst in the latter, there is no rule by which they can be determined.
In the present case, the complaint is that the defendants, by the use of steam power upon their road, have prevented persons before accustomed to travel the plaintiffs’ road, from continuing to do so. It is not pretended that the defendants have erected w caused any physical obstruction against such travelling, and *321if such has in truth been the effect of the use of engines, it is an effect founded upon the fears and apprehensions of accident and danger, which the public may entertain, or upon the advantages and facilities which the defendants themselves have offered to the public. And it would be difficult, if not absolutely impossible to determine whether the reduction of the plaintiffs’ tolls, was caused by the inducements which the defendants have offered to the public, by an easier and more expeditious mode of conveyance, or by the alarm and apprehension excited by the use of steam power.
Again, the complaint here,is for the disturbance of a franchise, which cannot be effected except by the exercise of some unlawful practices, as by a physical obstruction of the road itself, by unlawfully creating a nuisance upon or near the road, by unlawful menaces or false and fraudulent representations and persuasions, thereby preventing persons from using the plaintiffs’ road as before. These constitute the injury of disturbance. But it cannot arise from the performance of a lawful act.
If then the defendants are authorized by their charter, to use steam engines upon their road, whatever may be their legal responsibility in many cases, for private injuries resulting from such use, they arc not responsible"for the injury of disturbance of the plaintiffs’ franchise, unless they have exercised that rigid in an extraordinary and unlawful manner not contemplated or warranted by the legislature.
I am of opinion that the pleas demurred to, are not only good in form, but in substance; and are a legal answer to the four counts to which they are pleaded; and that the demurrer should be overruled.
Horneeower, C. J., and Ford, White and Dayton, Justices, concurred.
Demurrer overruled.
