. The iron dome under which it is mounted is 39 feet inside diameter, 

 and very heavy. A 4-horse gas-engine in the basement furnishes the 

 jtower for moving it and managing the shutter. It is possible to raise 

 the shutter, turn the dome to any part of the sky, and have the tele- 

 scojie pointed upon any designated object within five minutes after enter- 

 ing the building. The same engine drives a small Edison dynamic 

 machine, which supplies electric light to all parts of the observatory 

 and furnishes electric currents for spectroscopic work.
