38 THE WORK OF THE STOCK EXCHANGE 
truth (but not the whole truth) that the higher organization 
of markets has sometimes made it easier for reckless and unin- 
formed people to injure themselves through speculation, just 
as it is easier today to be killed by being run over by a steam 
locomotive or an automobile than it formerly was by a stage- 
coach. Yet, just as this latter fact does not constitute a valid 
reason for urging that steam railways or automobiles be

people must somehow be taught not to speculate foolishly, just 
as we are all learning to avoid getting in front of locomotives 
or automobiles. 
Future Marketing Probabilities.—The organization of 
exchanges has been accomplished in comparatively recent times. 
Yet so important a factor in the economic and social progress 
of world civilization have they already proved, that not only 
their permanence in the present economic machinery of the 
world, but also their continued evolution in the future along 
significant lines is assured. Great as are their functions and 
beneficial services to mankind today, nevertheless it is obvious 
to the economic historian that their present development is only 
a stage in their larger and continuous evolution. Without 
indulging in fanciful predictions, it is nevertheless interesting 
to conjecture along what lines this future evolution of the 
organized markets is likely to occur. 
In the first place, it seems inevitable that the production and 
consumption of many commodities will considerably increase 
luring the coming century, and that they will consequently 
come to be considered as staples. It will become more and 
more dangerous and expensive to buy and sell such commodi- 
ties in their present loose-jointed, unorganized, and precarious 
markets, and accordingly exchanges may gradually be estab- 
lished for their more economical sale and distribution. Many
