Unlike humans, stones, even if they hang around doing nothing, don't get out of shape too quickly. In order to keep their shape, they vehemently resist the forces of time and weathering, and the various forms of mechanical tampering that men have come up with through the ages. Yes, in the end they might sometimes have too submit to crushers and the indignities of huge splitting and sawing machines. But I suspect, if they had their way, if they had their choice, they'd like to be appreciated for the shapes they come in, the way God made them. An authentic dry stone waller, if he's being true to the nature of the material he is gathering, tries not to change the shape of the stones he's been called upon to use. A little chipping here and there, a splitting by hand, of larger (overweight?) stones is acceptable. Generally however, if not exactly what is needed, the shapes they come in, almost always suggest how they could become 'fit' enough, with just a little human coaxing (coaching?), and only by 'exercising' enough restraint on our part.
