Swasey Observatory 349 



The equatorial telescope is one of the standard Warner and 

 Swasey type, similar in design to the 26" telescope in the United 

 States Naval Observatory, the 36" Lick and the 40" Yerkes, and 

 others of similar size designed and constructed by that company. 



The column supporting the equatorial head is of cast iron, rect- 

 angular in shape, with broad base,extendingunder the floor at the

north side, and mounted on four heavy steel beams which are built 

 into the walls to keep the instrument from contact with the floor. 

 The upper section of the iron column contains the driving 

 clock, which is protected from di Lst and injury by plate glass doors. 

 The lower part of the column is utilized for the driving weights 

 which run the clock.
