“The coal and limestone within the bounds of the lands thus reserved remained the property of the superior under his title to the plenum dominium. And it cannot be doubted, that as a separate estate it might at any time have been conveyed to a third party. What was reserved was a proprietory right in the subject of the reservation, namely, coal and limestone.”
“Reserving always to us, the said Duchess of Hamilton, our heirs and successors, all and whole the coal and limestone within the whole bounds of the lands above disponed, so that we and our foresaids may set down coal pits, shanks, and sinks, and win coal and limestone within any part of the said lands, and may have liberty to make all engines and easements necessary, with free ish and entry for the making, keeping, sale, and away taking thereof, we and our foresaids always giving satisfaction to the said Gabriel Hamilton and his foresaids for any loss, skaith, or damage they shall sustain by the down setting of any such coalpits, sinks, or shanks, or by the winning of the said coal and limestone, or by the roads and passages for the away carrying of the same.”
“On the same principle, I hold it to be equally objectionable to bring the coals of an adjoining estate into Cambuslang, and carry them underground through that property into an adjoining coal field. This could not be done on the surface of the lands, and it can as little be done in the evacuated waste forming a tunnel underground.”
