The Park Governments of Chicago 145 



Park station, with the operation of only two boilers, as was 

 formerly employed for four boilers. It is unnecessary to have 

 a coal passer and a fireman on each watch. The services of three 

 coal passers could be dispensed with, as the firemen can easily 

 handle the coal. In the winter season one extra man might be 

 added. A saving of $1,260 per year may readily be effected by 

 this reduction of force. 



LINCOLN PARK COMMISSIONERS 



The Lincoln Park Commissioners on April 27, 1908, made a 

 fifteen-year contract with the Sanitary District for electric power. 

 This contract calls for the usual municipal rate of $1.25 per horse 

 power per month for 12-hour power and $2.20 per horse power 

 per month for 24-hour power. An average of the three highest 

 15-minute peaks during the month determines the horsepower. 

 The current is measured at the Lincoln Park switchboard, an 

 allowance being made on the recording watt meter for losses from 

 the Western Avenue sub-station to the switchboard. In addition, 

 there is an annual charge of five per cent, on the cost of install- 

 ing the transmission line. The Park Board maintains the cir- 

 cuit. 



At present there are approximately 844 electric arc lamps 

 installed, but the installation has been so rapid and irregular that 

 an estimate of cost per lamp per year is difficult. The cost of 

 current alone should be approximately the same as that of the 

 West Park Board. The operating cost would be less, because 

 the circuits all radiate from one sub-station. 



Since the electric installation, the steam power plant has 

 been disposed of and the steam developed now is used for the 

 laundry, heating the power plant, and furnishing steam to one 

 small vertical engine which operates a lathe and two other small 

 machines. A better arrangement would be to install a small 

 electric motor to operate these machines. Since the electric 

 power purchased is based on the peak load which occurs at night, 

 the cost for electric motor drive would be practically nothing. 



The arrangement of the boiler plant now in use at the power 

 house is very awkward. Two boilers are located in the coal room,
