drained soil. The canoe-cedar is one of the most beautiful 

 conifers in the Pinetum. 



The Japanese arbor-vitse, Thuja Standishii, is a very beau- 

 tiful decorative plant. It has a somewhat broadly pyramidal 

 habit, and the foliage, with a pale green aspect, does not change 

 throughout the year, or only very slightly in winter. The tree 

 requires a moist deep soil to appear at its best. 



The oriental arbor-vitse, Thuja orientalis, from eastern Asia, 

 has usually a strictly pyramidal habit. Branches present the 

 appearance of being densely folded together. The foliage is 

 a bright olive-green color which it retains well throughout the 

 winter. Many named varieties are in cultivation, with dwarf, 

 densely columnar, and pendulous habits. About fifteen years 

 ago a quantity of seeds of the oriental arbor-vitse, collected in 

 China, were given to the writer and several hundred seedlings 

 were raised. They were planted on a steep, moist, sandy slope 

 facing the northeast in Durand-Eastman Park, Rochester. 

 They are now seven to ten feet tall and are nearly all narrowly 

 pyramidal in habit, some much more so than others. The effect 

 of this large group on this slope is excellent. 



Cypress. 



The Sawara cypress, Chama;cyparis (Retinispora) pisifera, 

 from Japan, is a very popular evergreen in American gardens. 

 The typical form is a beautiful ornamental tree when grown to 

 one stem. The type should be much more widely grown, and 

 as an ornamental it is not surpassed by any of the seminal or 

 vegetative forms that have been produced from it. The Sawara 

 cypress, or any of its varieties, should always be planted in 

 positions well protected from the sweep of the prevailing cold 

 winds in moist good soil. The var. filifera, with long slender 

 branches, becomes in time a broad round dome and very deco-
