THE DAIEY THRONG IN NEWSPAPER ROW: THE MANHATTAN END OE 



BROOKLYN BRIDGE 



Brooklyn has a population of nearly two millions, and during the rush hours it seems as 

 if the whole borough wants to cross the Brooklyn Bridge at once. Yet every East River 

 tube and each of the other three highway bridges is doing its best to relieve the crush at 

 City Hall Square. 



lems involved, it makes every other aque- 

 duct of ancient and modern times look 

 like a pigmy project. If it were diverted 

 into Fifth avenue, it would be a stream 

 waist deep, flowing at the rate of four 

 miles an hour. 



A day's supply would fill a cistern a 

 hundred feet in diameter and nearly two 

 miles deep. Each human being inhabit- 

 ing the earth could get two and a half 

 pints of water every twenty-four hours 

 from its capacity flow. 



Costing for each mile eight or ten times 

 as much as a thoroughly modern double- 

 tracked railroad, to carry a correspond- 

 ing volume of water thirty great steel 

 pipes four feet in diameter would have 

 been required. Such a pipe-line would 

 have cost twice as much as a tunnel of 

 equal capacity through the eternal bed- 

 rock. It has been estimated that, within 

 the city limits alone, fifteen million dollars 



was saved by the types of construction 

 adopted rather than the use of steel 

 piping, to say nothing of the tremendous 

 cost of renewals which the latter would 

 have entailed. 



THE BUILDING OE THE CATSKILE 

 AQUEDUCT 



The Catskill system, with all its tre- 

 mendous capacity, is not expected to 

 bear the whole burden of supplying the 

 metropolis. The Croton Aqueduct, though 

 long since outgrown, is still a sizable 

 waterway itself, for it could supply every 

 inhabitant of the globe with a pint and a 

 half of water a day. As an ally it will be 

 an invaluable aid to the Catskill stream. 

 Between them they will have, when the 

 Schoharie dams are built, an aggregate 

 capacity of eight hundred million gallons 

 a day — half a gallon per capita for the 

 whole world.
