a deep green color. Notice too that this Mount Atlas 

 Cedar throws up its branches in perfect vase form 

 which is characteristic of the Atlantica, whereas the 

 Libani has a distinct horizontal swing to its branches. 



Let us now come back to the junction of the Walk 

 by the black alder and continue along its course 

 toward Swan Boat Lake. On the right, about oppo- 

 site a second offshoot of the Walk to the left, you 

 will find thick clumps of ginseng or Aralia quinque- 

 folia, which you recognize at once by its five leaves. 

 Great masses of Deutzia gracilis bank both sides of 

 this second offshoot of path which climbs a few steps 

 and runs around in a short arc to meet the Drive. We 

 will not follow it now, but will keep on with the path 

 which runs under the Three-Arched-Bridge. 



On your left, about midway between the offshoot 

 of the path and the Bridge, close by the Walk and 

 leaning over it are some trees which you will do well 

 to look at closely. They are Caucasian walnuts and 

 you can know them easily by their long compound 

 leaves made up of from eleven to twenty-odd smooth 

 glossy leaflets. The leaflets have crisped margins. 

 The bark of these trees is curiously streaked or marked 

 with reddish brown lines which make you think of the 

 Halesia or silver bell. Don't miss them, and if possible 

 don't fail to look for their strings of fruits which 

 develop from long, drooping racemes of flowers. It 

 is the wing on the fruit which has given the tree its 

 botanical name Pterocarya. Close by the Bridge, on 

 your left, is English yew. As you come out from 

 under the Bridge and pass the next offshoot of path"
