I see that child who lay upon her bosom and who bore my name, a man winning his way up in that path of life which once was mine. I see him winning it so well, that my name is made illustrious there by the light of his. I see the blots I threw upon it, faded away. I see him, fore-most of just judges and honoured men, bringing a boy of my name, with a forehead that I know and golden hair, to this place—then fair to look upon, with not a trace of this day's disfigurement—and I hear him tell the child my story, with a tender and a faltering voice.
Some hearths will, with a little assistance from your SDS chisel drill, come out in one or two pieces – straight to the skip usually. Often all you will have to do is use the SDS to knock out a little of the mortar used to bed the hearth onto. If you are unlucky the hearth will be inches of solid concrete. If so you have two choices: use the SDS to get rid of it all (you may need to hire something more powerful) or use this as a basis for your next hearth. If you leave a granite or slate hearth in place as a foundation score it well with a cutting disc so your mortar will bond to it.
