Once it becomes of seed-bearing age, the remarkable massing 
or clustering of its cones adds greatly to its beauty and attract- 
iveness. Whenever this variety can be procured to take the 
place in grouping of, or in association with, the Austrian, it 
should be planted ; but at present it is so rare that we can only 
look for its being placed in some prominent single position upon 
the lawn. 
The Swiss Stone Pine. Pinus cembra. — The Cembrian or 
Swiss Stone Pine is a very compact and somewhat slow-growing 
variety, resembling the white pine, except that its foliage is 
shorter and more stiff. It. is well suited to the foreground of 
groups of that variety. It is perfectly hardy, and very handsome. 
The Pitch Pine. Pinus rigida . — For the purpose of creating 
a wild and somewhat romantic effect upon some rocky hillside, 
or in the formation of a broken group, the pitch pine may be 
used with good effect; but as a tree for general use in orna- 
mental planting, the dark rich green of its foliage, and the 
facility with which it can be grown in any soil, are its only 
claims to notice. 
The Norway Pine. Pinus resinosa . — The Red or Norway 
Pine is of rapid growth, quite handsome while young, its foliage 
being a dark rich green ; but as it acquires age it becomes some- 
times too open and sparse of foliage to- render it specially desir- 
able, except in large grounds. In the formation of masses we 
should use one or more of this variety. 
The Mammoth Tree of California. Sequoia gigantea . — 
The growth and appearance of this new California evergreen is 
extremely graceful and beautiful. It is known under the various 
names of Washing tonia, Wellingtonia , and Bastard Cedar, and 
was originally classed as a Taxodium , supposing it to belong to 
the same genus as the deciduous cypress. It was first discovered 
in 1831. It has been found growing abundantly on the mount- 
ains of Santa Cruz, about sixty miles from Monterey, in Cali-
