Opinion by
The rule of law upon which appellant relies is well settled in Pennsylvania, but difficulties frequently arise in applying it to the facts of a particular case. The rule is that in a grant of all the coal underlying a tract of land, in the absence of an express waiver, or the use of words from which the intention to waive clearly appears, there is imposed upon the mineral estate the servitude of surface support. In our state there has been no departure from this rule which has been recognized and asserted from Jones v. Wagner,
Decree affirmed at the cost of the appellant.
