Conversion is not the smooth, easy-going process some men seem to think. It is wounding work, of course, this breaking of the hearts, but without wounding there is no saving.… Where there is grafting there is a cutting, the scion must be let in with a wound; to stick it onto the outside or tie it on with a string would be of no use. Heart must be set to heart and back to back, or there will be no sap from root to branch, and this I say, must be done by a wound.4
