A curious examination of the map of Brooklyn bIiows that the 

 foot of South Sixth street is much nearer the area of unimproved 

 property in the western district than Fulton ferry, and is at about 

 the same distance, in a direct line, from the corner of Fulton and 

 Clinton avenues, and about 7,200 feet nearer East Xew York, at the 

 end of Broadway. It follows therefore that the percentage of annual 

 increase in future income favors the location under discussion, from its 

 morei'eady access to the natural district of development as to distances 

 ahd as to grades. 



If however, we assume the Union ferry travel as a local item, not 

 likely to use this means of transit and that its 40,000,000 and more of 

 present annual passage will be locally confined (an assumption with- 

 out proper basis of argument since so much of upper and eastern 

 New York seeks that avenue of transit), a simple rule of proportion 

 shows that if these local ferries, communicating with twelve and one- 

 half wards of the city, representing in 1865 a population of 175,000, 

 had this business, the remaining eight and a half wards of 121,000 

 people controlled a ferriage of 27,500,000 or sixty-seven and one-half 

 per cent strictly an eastern district travel. 



At the rate then of but two cents toll, tlie passenger income of 



1870, estimated on the basis of 1865, would be 27,500,000 at 



two cents $550,000 



To this the assumed income of $640 per day for 3,200 



vehicles, at eighty trips of four boats, for 300 days, is . 192 j 000 

 The annual value of the warehouses, &c., taken at twenty 

 per cent on their cost, less five per cent taxes, repairs, 

 &c., or fifteen per cent net, is 262 ? 500 



Total $1,004,500 



From which the deductions for operation of engines, 

 bridges, gates, &c., repairs, superintendence, &c., may be 

 assumed at 



Engines $20,000 



Bridge, gates &c 18 , 250 



Sea wall and tunnels 7 ^ 300 



Superintendence 20,000 



Bepairs, &c 84,450 



Taxes four per cent on $3,000,000 120 , 000 220 , 000 



Net income $784,500 



Or 13.07 per cent on cost at $6,000,000.
