John D. Rockefeller：Random Reminiscences of Men and Events, Additional Excerpt 47

Taking our experiences in many hundreds of trees of various kinds in and out of season, and including the time when we were learning the art, our total loss has been something less than 10 per cent., probably more nearly 6 or 7 per cent. A whole tree-moving campaign in a single season has been accomplished with a loss of about 3 per cent. I am willing to admit that in the case of the larger trees the growth has been retarded perhaps two years, but this is a small matter, for people no longer young wish to get the effects they desire at once, and the modern tree-mover does it. We have grouped and arranged clumps of big spruces to fit the purposes we were aiming for, and sometimes have completely covered a hillside with them. Oaks we have not been successful with except when comparatively young, and we don't try to move oaks and hickories when they have come near to maturity; but we have made some successful experiments with bass wood, and one of these we have moved three times without injury. Birches have generally baffled us, but evergreens, except cedars, have been almost invariably successfully handled.
