or in single specimens on prominent points. They are adapted to a 

 variety of soils and easily transplanted. 



T. occidentalis Linn. (11) is our native northern Arborvilce. or White 

 Cedar, a medium-sized tree, narrowly conical, with compact head, 

 which furnishes a large number of useful nurserymen's varieties with 

 variegated foliage, dwarf habit, 

 etc. The foliage is pale green, 

 becoming brownish in winter. 

 It is fine for avenue planting 

 and also makes a perfect 

 hedge. 



T. gigantea Nutt. (12), the 

 Pacific Coast Giant Arborvitcc, 

 reaches a height of over two 

 hundred feet, grows very rap- 

 idly, and is most beautiful; 

 the short, closely set, horizontal 

 branches are pendulous at the 

 tip. Coming from a moist, 

 mild climate, it can be used 

 only for southern planting, un- 

 less the seed is brought from 

 Montana. 



The Japanese T. Japonica 

 Maxim. (13), semi-hardy in the 

 north, and the Persian T. ori- 

 entalis Linn. (14), fit only for 

 southern ranges, offer hardly 

 any superior points. 



Thuyopsis. T. dolohrata 

 nana S. & Z. (15), Tom Thumb, 

 a Japanese Arborvitae of small stature, is one of the most beautiful of 

 this group, semi-hardy as far north as Massachusetts. 



Juniperus. Juniper or Red Cedar. This genus contains some thirty- 

 five species, mostly small trees, of pyramidal and even columnar form, and 

 rather stiff habit, and shrubs, hence useful in small places, the low forms 

 for rocky slopes, covering of sand banks, planting of lanes, windbreaks, 

 screens, etc. They are less symmetrical than other conifers. They 

 are, as a rule, adaptive to soil conditions, from sand to lime, from swamp
