On the easterly corner of the conservatory terrace, oppo- 
site the retinisporas, is a part of the juniper, or red cedar 
(Juniperus), collection. ‘The remaining and larger portion 
of this collection will be found on the easterly end of the 
area lying between the driveway and the traffic-road south 
of range 1. In these two areas will be found many species 
and varieties of these plants. The common juniper, of 
north temperate regions, is one of these; also the Irish 
juniper, a form of this, of compact and strict habit. The 
red cedar, so common in a wild state in the grounds of 
the Garden, finds representatives in many horticultural 
forms. The savin juniper, of Europe and northern Asia, 
and its American representative, the Waukegan juniper, 
of northern North America, are both neat low-growing 
sorts. The Chinese juniper, and its striking form, of 
columnar habit, known as variety pyramidalis, are each 
present in a number of specimens. There are still other 
varities of the Chinese juniper represented here, including 
Phiizertana, one of the best dwarf conifers. 
t the westerly end of this area is the arbor vitae group 
(Thuja). The species of this genus produce a durable wood 
which is of especial value where there is contact with the 
soil. The Japanese arbor vitae is represented by several 
specimens. ‘The common arbor vitae, from northeastern 
North America, is fully represented, not only by the 
typical form, but by many horticultural varieties, some of 
them very decorative; the wood of this tree is valued for 
fence posts, railway ties, etc., and from its young branches 
fluid extracts and tinctures are made which are used in 
medicine. The Chinese arbor vitae, from China and 
Japan, has a number of specimens representing it and some 
of its horticultural forms; this as a decorative plant in this 
vicinity is not satisfactory, as it is not quite hardy, the 
branches often killing back in the winter and the foliage 
burning badly. 
The maiden-hair tree family (Ginkgoaceae) is represented 
by a single species, the maiden-hair tree, several specimens
