Mr. Blodget made the following remarks upon certain 

 features of Industrial Migrations as shown in the manufac- 

 tures of Philadelphia. 



The development of many of the industries of Philadelphia presents 

 characteristics strikingly resembling those of nations conspicuous in his- 

 tory for industrial prosperity. History as usually written affords but an 

 imperfect view of the real causes of national growth, and we are led to in- 

 fer that the employment of the people is altogether secondary and subordi- 

 nate. One of the best of the more authentic and better works which should 

 lake the place of histories is a treatise by the Marquis De Uztariz, on 

 the industrial economy of Spain, originally printed in 1724, and reprinted 

 in England in 1751, by John Kippax, under the patronage of the Prince of 

 Wales. It gives a vivid picture of the great industries in wool and silk 

 which made Spain rich and prosperous before the gold of the New World 

 was known. Seville, Granada, Cordova and Toledo became magnificent 

 cities through these industries in wool and silk, and sent Spanish cloths 

 and embroideries to every country of Europe. Seville alone had 16,000 

 looms, employing 48,000 persons, and maintaining directly 12,000 families, 

 or 60,000 persons. But this statesman of that early period found that great 

 misfortunes followed the neglect of manufactures, and that a false policy 

 of taxation had transferred many of them to France and the Low Coun- 

 tries. He wrote earnestly rn resistance of that policy, and struggled to 

 restore the ancient splendor of those great cities. The Spanish ruling class 

 was infatuated with the gold and silver of the American colonies, however, 

 and the first great industi'ial migration carried what remained of them into 

 the Low Countries, from which they were subsequently drawn partly into 

 France, by the skill of Minister Colbert, and still later into England.* 



*The origin of tliese industries of Spain is so forcibly told by Marquis De 

 Uztariz that I quote from his chapter citing the laws of King Ferdinand, Ferd-
