MISCELLANEOUS NEWS AND NOTES ABOUT TREES 
A Tree Growing Within Another. 
A correspondent of the Scientific 
American sends to that journal the 
accompanying picture of a curious 
old Cryptomeria which he discovered 
growing within another in Japan, in 
TREE GROWING WITHIN ANOTHER 
1895. As is usual with natural curios- 
ities in Japan, there was a small 
shrine with stone lanterns, and across 
the road a tea house for pilgrims. 
The trunk said to be 65 feet in cir- 
cumference and the trunk of the inner 
tree to be 9 feet in circumference. 
The outer trunk is about 30 feet high. 
The outer tree was destroyed by the 
eruption of Osama Yama 130 years 
ago. The inner tree is about no 
years old.

The Elm Leaf Beetle 
The elm beetle made its first ap- 
pearance in this country in Balti- 
more, supposedly brought from Eu- 
rope on an importation of elms. It 
spread from Baltimore to North Car- 
olina, New England and New York, 
and last year was found as far west 
as Dayton, O. 
Dr. L. O. Howard, U. S. entomolo- 
gist, predicts that the elm beetle will 
spread and prove particularly de- 
structive in the states between Alle- 
gheny and Rocky mountains, especial- 
ly north of Tennessee and Arkansas. 
Elm beetles are near relatives of 
A— ELM LEAF BEETLE; B— GROUP OF 
EGGS MUCH ENLARGED; C— FULL 
GROWN LARVAE 
and resemble the striped cucumber 
beetle. They hibernate during win- 
ter in protected places and appear in 
early spring. Each female lays about 
500 eggs, and hatching takes place 
four to six days later. The larvae 
attain full growth in 15 to 20 days. 
Both beetle and larvae attack the 
leaves, usually at the tree top first. 
Spraying is the principal remedy. 
Arsenate of lead, or disparene, five 
pounds to 50 gallons of water, is rec- 
ommended. Spray as soon as trees 
are in full leaf and if not entirely 
effective two or three weeks later and 
until the pest is exterminated.

A Large Oak Struck by Lightning 
Dr. N. L. Britton, of the New York 
Botanical Garden, in a recent issue 
of the journal of that institution tells 
of the largest pin oak (Quercus palus- 
tris) in the Garden being struck during 
a thunderstorm. It cannot recover 
New York Botanical Garden 
from the damage which it suffered. 
The tree stands a few hundred feet 
southeast of the eastern end of the 
long stone bridge across the valley 
of the Bronx river, in the portion of 
the grounds set aside for the arbore- 
tum, and just south of the main drive- 
way now approaching completion. In 
developing the general p'an of the 
grounds this driveway was located in 
position and grade especially with 
reference to the preservation of this 
tree, and it is a great disappointment 
that it must be lost. ■ The trunk is 
forked about 15 feet above the base, 
and the lightning shock has split this 
fork deeply and loosened the bark 
from the ground to a height of about 
25 feet; the energy of the discharge 
hurled large pieces of bark to a dis- 
tance of 40 feet from the tree, and 
plowed up the ground on all sides of 
it along the larger roots. The gen- 
eral effect of the lightning stroke is 
shown in the photograph. 
During the development of the gar- 
den, a number of trees have been 
killed by lightning, which does not 
seem to be particular as to what kind 
it selects as it has already included 
a tulip tree, a chestnut, a hemlock, 
an American elm, and a pin oak and 
none of these have recovered from 
the damage, which is not at all con- 
fined to bark and outer layers, but ap- 
parently affects the entire trunk.

Good Arbor Day Work in Denver 
By direction of Mayor Speer, the 
city of Denver donated to citizens 
of Denver, who would plant and care 
for them. 10,000 trees on Arbor Day, 
April 20, 1906. They consisted large- 
ly of e'.m and maple, with a few 
locusts. There was a great demand 
for the trees, and they could have easi- 
ly given away to deserving applicants, 
double the amount. The trees ranged 
in size from i foot to 3 feet. To 
each tree was attached a tag contain- 
ing instructions as to how and where 
to plant. The mayor was very much 
gratified with the success of the en- 
terprise, which was an experiment, 
and it will be repeated next year when 
more trees will be distributed.
