ABSTRACT
THE brief summary of the causes of local style given above 1 shows that they are of two classes: (1) Those which arose spontaneously from natural conditions such as the available supply of stone and timber and the character of the people; they are likely to extend so far as and no further than the conditions which produced them. (2) Those of more artificial character, concerned with stylistic matters. These are the nicer questions of design; they result from more artificial or exceptional sources such as individual genius and its imitators, sheer fashion and so forth; their province is likely to be more difficult to forecast.
