The opinion of the court was delivered,
On October 30th 1837, Lewis Peterson entered into articles of agreement with Thomas Kier and Samuel M. Kier, by which he leased to them and their assigns a certain lot or piece of ground owned by him in the county of Allegheny, and adjoining the Pennsylvania Canal, with the privilege on the said premises to bore salt-wells and erect all manner of buildings necessary or useful in the prosecution of the manufacture of salt; and to use all coal in the hill in the rear of the said premises within the boundary lines of said Peterson’s land that may be necessary and proper to the successful prosecution of said manufacture, together with the right of taking from the before-described premises timber and stone to erect and keep in repair the establishment therein contemplated. It was also agreed that the said Peterson should be at liberty to lay a railroad near Humes’ line, from the coal-bank on the hill to the canal, provided it does not interfere with the interests of lessees in the conduct of their works and improvements. It was further agreed that the lease should endure as long as the salt-wells therein contemplated to be established should be carried on by the said Thomas Kier and Samuel M. Kier, the survivor of them or by their assigns. Then followed a
In consideration of which the said Thomas Kier and Samuel M. Kier agree to pay unto the said Lewis Peterson the one-twelfth barrel of' all the salt made on the said premises, to be delivered to the said Lewis Peterson, or his authorized agent, at the works on the said premises, on the first days of January, April, July, and October in each and every year during the continuance of this lease.
It will therefore be perceived that this instrument gave a life estate to the Kiers and the survivor, to endure as long as the salt-wells shall be carried on by them or their assigns, with two conditions, the first of which, as to putting the salt-wells in operation, has been fulfilled, and has therefore no longer any existence, and the second, as to letting the salt-wells remain idle or out of use for three continuous years, has never been broken. In fact it is conceded that all the covenants and agreements of the lessees have been strictly complied with, including the payment of the stipulated rent.
The lessees, therefore, had a freehold estate for life in these premises on condition, without any other restriction or limitation except what is expressly stated on the face of the articles of agreement. Subject only to this, these lessees were tenants for life of this property, and with all the rights belonging to such an estate.
The defendants went into possession of the demised premises, sunk a well in 1889, erected works, and commenced and continued the manufacture of salt; and about 1845 carbon oil, or petroleum, arose in the well in connection with the salt water, and the real question is, to whom does this oil belong, to the lessor or the lessees ? The oil must be separated ’ from the salt water, or the lessees cannot carry on their manufacture of salt, and they are clearly not obliged to keep it if they do not think it expedient, but may let it run into the canal as they did at first.
They are certainly not guilty of either legal or equitable waste, because the well through which the oil reaches the surface was
If mines are already opened, or if the lease permits their being opened, it is not waste for the tenant to work them even to exhaustion. Nor would it be waste to open new shafts or pits to follow the same vein. So as to saltworks: if there is am existing salt-well and works, it would not be waste to dig a new salt-well in connection with it: Findlay v. Smith, 6 Munford 134. There is therefore no charge of waste of any kind against the lessees.
If this had been an open spring, throwing out salt water, and finally petroleum also, could there be any doubt that it would be a part of the accruing profits ? So if it had been an open salt-well, would it not be in the samé category ? What difference, then, is there between these cases and a salt-well opened in express conformity to the articles of agreement ? It is the same as if it had been there before the lease was signed.
Petroleum or rock oil is essentially composed of carbon and hydrogen, and is a liquid inflammable substance or bitumen exuding from the earth, and is collected in various parts of the world — on the surface of the water, in wells and fountains, or oozing from cavities in rocks.
In the decomposition of vegetable substances, there are formed besides carburetted hydrogen, exhalations of which are of frequent occurrence in rock salt formations, liquid and solid hydrocarbons, such as naptha and petroleum, or mineral oil, mineral tar.
In Marietta, in the state of Ohio, the inflammable gas is a constant attendant upon brine springs, so that its appearance while boring in search of rock salt is looked upon as an indication of a favourable result; and in China the inflammable gas has been used to boil the brine, and also to heat and light the buildings in which the salt is prepared. On the shores of the Caspian Sea there is a tract called the Field of Fire, which continually emits inflammable gas, while springs of naptha and petroleum occur in the same vicinity.
On the surface of the Dead Sea, which is rery salt, asphalte is found in a soft or liquid as well-as a solid state, and it is said by high authority that bitumen in small particles hardly visible, but distinguishable by the smell, occurs in all the minerals of the saliferous system.
The presence therefore of petroleum or mineral oil is naturally to be expected in the salt formation west of the Allegheny Mountains, and although its great value has not been fully appreciated until within a few years, still if it comes up as in the present
Judgment reversed, and judgment entered for the defendant.
