wave their royal plumes of feathery green to every 

 rocking breeze. What graceful trees they are ! 



From this arm, pass southerly, following the east- 

 erly border of the Drive. You pass Japan quince, on 

 your right, honey locust on your left, resplendent in 

 black bark and fierce thorns. These honey locusts are 

 about opposite the lamp here. Beyond them, by the edge 

 of the Lake are European elder, full of little "cones," 

 jet black against the blue of the sky; flowering dog-

 their white fluffs of bloom. Beyond the fringe trees 

 you will see a quartet of the shrubby trefoil, of the rue 

 family, Rutacea. You must have met this tree several

 of the Park, and their leaves, made up of three leaf- 

 lets, are no doubt now quite familiar to you. You

 trees in October. Then their feathery masses have
