The transit room is 28x13 feet and 8 feet high, and has 
three slits 17 inches wide in the walls and roof for meridian 
observations. Each slit has a brick pier placed centrally 
under it and isolated from the floor and ground surface. The 
2,5-inch transit instrument is mounted on the western pier. 
The sidereal clock is mounted on a brick pier 7 feet high, in the 
southwest corner of the room, and faces the transit instru-

the central pier is usually occupied by the theodolite. The 
switch-board is on the south side and the barometer and the 
thermometer shelter on the north side of the transit room. 
The floor of the transit room is 742 feet above sea level. 
The cone which shelters the 2} inch altitude and azimuth 
instrument is 13 feet in diameter at the base and its apex is 10 
feet above the floor. It is divided into two equal parts by a slit
