somewhat more expensive than when this table w r as made, these 

 figures may be taken at $85 and $53, although such costs imply 

 small developments in units of not exceeding about 500 horse- 

 power. In large units of from 3000 to 5000 horsepower, 

 steam power may be developed considerably cheaper than this. 

 Nevertheless it is still true that steam power will cost more than 

 water power. We may profitably inquire then why, with so much 

 undeveloped water power in the State, the more expensive steam 

 power has developed to a greater extent relatively than water 

 power. 



Steam power. Let us consider the following tabulation of steam 

 power in the census years from 1900-1870, inclusive, in the States 

 of Connecticut, Massachusetts, Rhode Island and New York : 



1900 1890 1880 1870 



No. of H. P. No. of H. P. No. of H. P. No. of H. P. 



Connecticut 178,708 98,038 57,027 25,979 



Massachusetts 579,1.10 355,226 171,397 78,502 



Rhode Island 115,876 85,327 41,335 23,546 



New York 677,219 537,447 234,795 126,107 



Water power. The following tabulation shows the development 

 of water power in the census years 1900-1870, inclusive, in the four 

 States :

 States for the same period :
