TWO BEA.UT1FUL AND VALUABLE TREES. 
The Nivea or Giant White Poplar must not be 
confounded with the common silver-leaved poplar, 
which has a crooked and sprawling habit of 
growth and sprouts so badly from the roots. 
The Nivea is very hardy and a very rapid 
grower with fine rich foliage — green on the upper 
side and downy white on the other. It grows 
straight and soon makes an imposing tree. It will 
sprout if the roots are broken, but I think it will 
not otherwise. It is fine for parks or avenues 
and a noble road tree. It grows readily from 
cuttings and makes a surprising growth the first 
year. 
Tne Boleana is a charming tree with leaves 
much like the Nivea. Its habit of growth is com- 
pact much like the Lombardy poplar. Unfortun- 
ately in our western states the latter has the bad 
habit of dying when about 15 years old. The Bo- 
leana, as far as I can learn, is a very rapid grow- 
ing and healthy tree, but it is exceedingly hard to 
propagate. If the cuttings can be first caloused 
they may grow. The most common method is 
either to bud on the Lombardy or graft a scion on 
a piece of twig of the Lombardy, this piece making 
the root, for the one will throw out roots and the 
other will not. I have used this method and 
though exercising the greatest care, only one in 
five or ten will live. All will start and then one 
after another will fade away. 
On account of the similarity of the two, I deter- 
mined to graft the Boleana on the roots of the 
Nivea. I made grafts about like apple root grafts 
and was surprised at the results. Nearly every one 
lived. They seemed mated exactly and com- 
menced growing with great vigor. The loth of 
July some were 2^ feet high. I am sure we will 
now have a much more vigorous tree than if grafted 
or budded on the Lombardy, which is so short 
lived. C. S. Harrison. 
PROPAGATING EUONYMUS RADIANS. 
Euonymus radicans has for several years past 
been scarce in the market. This is probably due 
to several causes among which are: Its abundant 
use in plantations and the extended time necessary 
to grow plants from seed or from the usual method 
of cuttings. Seed sown as soon as ripe germinate 
without difficulty. Cuttings made in August or 
September from half ripened wood is a successful 
method. Cuttings made from well ripened wood 
during the late autumn or winter months root read- 
ily. However, it requires two, three or four years 
to obtain marketable plants by either of the above 
methods if the cuttings are made from one to three 
or four inches long. The most economical method 
of propagating this plant appears to be as follow?: 
From old hedge or bush plants cut branches fifteen 
to twenty inches long and possessing several lateral 
shoots. Arrange all the severed ends together and 
place as many of the branches upright in a tub as 
can be loosely accommodated. Move the tub and 
branches to a cool greenhouse where abundant 
Itght, moisture and air are available and exclude 
direct sunlight or draughts. Each day pour only 
as much water in the tub as will be evaporated by 
the succeeding day. In the course of two weeks 
numerous roots will have formed at the base of 
each branch. The branches are then to be planted 
in cold frames and treated as young plants. Dur- 
ing winter protect the frames from intermittent 
freezing and thawing and by spring the plants will 
be well -rooted and saleable. iV method preferable 
to that is to plant the rooted cuttings in a single 
row on the rear end of a violet or carnation bed of 
a greenhouse and by spring the plants will have 
more, larger and a compact mass of roots. In 
either case the plants make no stem or leaf growth 
from the time the cuttings are taken until the 
plants are sold the next spring. The loss during 
propagation need not be over one or two per cent. 
This method of propagating is rarely emp'oyed 
and it is explained with the view that its employ- 
ment will be profitable to others adopting it. It 
is possible that plants so propagated are not of 
equal merit to plants having been grown for one 
year or longer in the open ground and having had 
a normal rest during the winter. The latter usually 
make a vigorous growth after planting w'lereas the 
others usually make little or no growth the first 
year. However, during the second year the 
growth of either plant will be as vigorous as the 
other whether propagated by one or the other 
method. Emil Mis c he. 
Conifers are not common in the tropics. This 
is no great dis-advantage. From a silvicultural 
standpoint, especially as far as the soil is con- 
cerned, there is little reason for the encourage- 
ment of conifers where quick growing broad-leaved 
species will grow. In certain parts of Cuba, es- 
pecially Pinar del Rio and the Isle of Pines, Pinus 
Cnbensis is common. It usually grows in the poor- 
est soils. * * * No doubt there are several spec- 
ies of conifers which will grow well in Cuba. Their 
scarcity in tropical countries is probably not be- 
cause they do not like the climate, but because they 
are overwhelmed and crowded out by broad-leaved 
kinds. There are, however, near relatives of the 
pines which thrive in the tropics and produce ex- 
cellent woods such as the Podocarpus. yrhri Gif-
