three feet high, with long, wide-spreading branches and open habit. 
This is a useful plant when it can be given sufficient space in which 
to spread, but is of course more open in habit than that form of the 
Red Cedar which sometimes grows on the exposed sea-cliffs of the 
Maine coast, and in such positions forming a wide mat only a few inches 
high, is perhaps more beautiful than any other prostrate Juniper. 
Seedlings and grafted plants of this form are growing in the 
Arboretum but are too young to show if they can retain in more 
favorable surroundings the extreme prostrate habit due no doubt, in 
part at least, to the exposed position of the wind-swept sea-cliffs where 
these plants have grown. Among conifers with more or less pendulous 
branches few are more beautiful than the pendulous form of the Red 
Cedar (var. pend ala). There are several of these trees in the collection, 
sent here from European nurseries or found in the country. They vary 
slightly among themselves but are all worth a place in the garden. 
Among the other varieties of the Red Cedar are several of compact 
habit and bright green leaves. The most distinct of these are perhaps 
the varieties elegantissimo, pyramidalis, Schottii and Chamberlaynii. 
They probably originated in European nurseries from which they came 
to the Arboretum. 
The Juniper of northeastern continental Asia, J. chinensis, is a valu- 
able tree and many of the varieties, especially those of dwarf habit, are 
popular. Some of these varieties are good garden plants, but others 
are usually so disfigured by the red spider that unless they are fre- 
quently and' carefully sprayed they are not worth growing. The best 
of these dwarf plants, the var. FJitzeriana, is a shrub with irregularly 
placed rather pendulous branches, which can be trained into a low broad 
pyramid a few feet high. The branches are sometimes broken by a 
heavy weight of snow, but nothing else seems to trouble this plant. 
There are other dwarf upright forms of the Chinese Juniper with green 
or with bright yellow leaves which are growing well here; and the form 
with prostrate branches forming a dense low mat found by Professor 
Sargent in Japan and named for him is the best of the Asiatic pros- 
trate Junipers in the collection. An even more prostrate plant, in this 
climate, at least, the most reliable and the fastest growing of prostrate 
Junipers is the North American Juniperus horizontalis. This is widely 
distributed from the sea-cliffs of the coast of Maine to the northern 
Rocky Mountains. The behavior here of Juniperus conferta is disap- 
pointing. It is the Japanese sand-dune prostrate Juniper, ranging from 
Saghalin in the north to the tropical Lu-chu Islands in the south. It 
was first noticed by Europeans on the shore of Hakkodate Bay in the 
extremely cold climate of southern Hokkaido. A plant from this region 
might be expected to be hardy here and it is believed that this Juniper 
would prove useful to plant on the sand-dunes of Cape Cod and other 
parts of the north Atlantic coast. In the Arboretum, however, it ex- 
ists only in sheltered positions and loses many branches every winter. 
This tenderness is due perhaps to the fact that it grows so late in the 
season that young wood does not become thoroughly ripened. When the 
right place is found for it Juniperus covferta with its pale green leaves 
will be one of the handsomest and most distinct prostrate Junipers. 
These Bulletins will now be discontinued until next spring.
