Compass, a circle 18 feet in diameter. The rays of the compass 
are paved with yellow, red, and black marble terrazzo. At the 
center of the compass is a bronze Armillary Sphere, serving as a 
sundial, and designed by Mr. Caparn. It bears the old classical 
sundial motto: 
Serene I stand amyddst ye flowres 
To tell ye passing of ye howres. 
East of the compass, in front of the main entrance to the Lab- 
oratory Building, is a Meridian Panel, or panel of terrestrial posi- 
tion. This was laid out with the cooperation of Mr. Weld Arnold, 
then of the School of Surveying, American Geographical Society, 
but now of Harvard University. The panel itself, of black Bel- 
gian marble terrazzo, has imbedded in it the geographical and 
magnetic meridians, and the following data:

CONSERVATORY GARDEN 
A short side trip to the south, past the Laboratory Building, will 
take one down the steps to the Conservatory Garden, containing 
two Waterlily Pools. The northern one is piped for heating 
water when necessary, and contains only tropical forms, including 
the Giant Waterlily (Victoria). The southern pool contains the 
hardy sorts that do not require heated water. These two pools 
were the gift of Mr. Alfred T. White. 
The flower borders, approximately 100’ * 30° on the east side 
and 100’ « 10’ on the west, are gay from June till frost with 
flowering annuals and bedding plants.
