THE ADVANCEMENT OF SCIENCE 



INDUSTRIAL MUSEUMS AND 



EFFICIENCY 1 



Art and natural history are now repre- 

 sented in New York City by material equal 

 to that collected in any of the chief centers 

 of the Old "World. More characteristically 

 American, however, would be an adequate 

 showing of our astounding agricultural, 

 mineral and industrial wealth. The proper 

 illustration of this could and should be 

 given by a group of special museums, 

 united under a common management, and 

 working in thorough harmony for the com- 

 mon aim of national education. The spe- 

 cial museums should be devoted to the fol- 

 lowing branches, each one of the institu- 

 tions being complete in itself : 



Electricity Historic records 



Steam Health and hygiene 

 Astronomy and naviga- Textiles 



tion Ceramics and clays 



Safety appliances Architecture 



Aviation Scenic embellishment 



Mechanical arts Horticulture 



Agriculture Eoads and road-build- 

 Mining ing materials 



Labor Commerce and trade 



Efficiency Printing and books 



Fifty years ago there was no art mu- 

 seum, and no museum of natural history in 

 this great city of New York. At the pres- 

 ent time we have both, as well as a mu- 

 seum of safety, but the only technical art 

 museum is that associated with the Cooper 

 Union for the Advancement of Science and 

 Art. This is a small, imique and valuable 

 technical art museum founded by and
