drons, althea, Eng-lish walnut, and other 

 half-hardy trees and shrubs. 



Among the striking- trees which remain 

 upon the lawn at the present time are good 

 specimens of Douglas fir, golden retinosp- 

 ora, blue spiuce and red cedar; and among 

 deciduous trees, Buffalo berry, wild olive, 

 Schwerdler's maple, grape leaved linden, 

 purple leaved birch, variegated ash and 

 Kentucky coffee tree, are all in good healthy 

 condition and succeeding admirably. 



Douglas fir planted eighteen or twenty 

 ago is now between 25 and 30 feet in height, 

 is vigorous, healthy and apparently entirely 

 hardy. This tree is intermediate in appear- 

 ance and external characteristics between 

 our native balsam and spruce. The leaves 

 are much longer than spruce and are soft, 

 being entirely without the prickly character- 



istics of white or blue spruce. Golden 

 Retinospora is a variation of the common 

 type Retinospo7 a plumosa. It must be con- 

 fessed that the tree is more beautiful in youth 

 than in maturity. When young — 5 to 10 

 years — it is compact, owing to the peculiar 

 character of its leaves and twigs, the general 

 expression is feathery and beautiful, but as it 

 grows older the branches become less densely 

 clothed with the plume like foliage and the 

 tree takes on a somewhat unclad expression 

 which detracts much from its beauty. For 

 best effects this tree should be planted in 

 clumps and in masses. In spring this foliage 

 is distinctly and markedly golden tipped. 

 The deep yellow tints fade off somewhat 

 during the summer, but it is a striking and 

 attractive form at most seasons of the year. 

 Blue spruce [Picea pungens) is so well known
