every year by the progress achieved in the transmission of 

 power; the second exists in small industries as well, and to 

 the same extent, as in the great ones (watchmakers, toymakers, 

 and so on) ; so that only the third remains in full force ; 

 but this factor as already mentioned in the text of this book, 

 is a social factor which entirely depends upon the degree of 

 development of the spirit of association amongst the pro- 

 ducers. As to Schwarz's figures relative to the higher pro- 

 ductivity of great spinning mills as compared with smaller 

 ones, it remains to be known whether the large mills which 

 he mentions are not more modern than the small ones, and 

 are not provided, therefore, with better machinery. One 

 conclusion of Schwarz is, however, absolutely correct: small 

 industries, unless they are engaged in the production of 

 artistic goods, as is the case at Paris, Lyons, Warsaw, Vienna, 

 and so on, can thrive only in connection with agriculture.
