A memorial rose garden has been planted around the sundial

One of the floating ferns, Azolla caroliniana, has been an object 

 of considerable popular interest this season. Last spring a handful 

 of the plants that wintered over in our conservatory was placed in 

 one of the pools of the brook in the Ecological Section. The plant 

 multiplies rapidly vegetatively and by September it had almost 

 completely covered the surface of the water for about 900 feet 

 from the Ecological Section to the terminal pool. On account of 

 its ability quickly to cover the surface of the water Azolla has been 

 utilized in Panama and elsewhere to help eradicate mosquitoes. 

 Where Azolla grows the mosquito larvae are not able to come to 

 the surface to breathe, and consequently die.
