THE NATIONAL NURSERYMAN

promising apples from known crosses augurs well for future 
work along this line, while the comparisons between parent 
varieties and seedlings give the most definite indications yet 
secured regarding the inheritance of apple characters. 
These inheritance data are admittedly incomplete since they 
come only from the first generation progeny of known 
parents; while two or more generations are necessary to 
give very convincing evidence as to heredity; yet the be¬ 
havior of these crosses is, scientifically, of equal or greater 
value than the practical utility of the new varieties. These, 
by the way, are named for counties in New York State. 
Those interested in work of this kind, either as apple 
growers or as students may obtain the bulletin, in either 
popular or regular edition, by writing to the Station for it.

CHINESE ARBOR VIT 2 E 
As a result of the work of plant introduction, some very 
valuable trees for planting" in various parts of the United 
States have been brought in from foreign countries. Among 
these the Chinese Arbor Vitae deserves S])ccial mention 
because of its qualities adapted for planting in dry regions. 
The Chinese Arbor Vitae is an evergreen tree that resem¬ 
bles the American Arbor Vitea closely in leaf characteristics, 
but it is altogether unlike it in regard to its soil and climatic 
requirements. 
The Chinese Arbor Vitae is found growing in very dry 
mountainous regions in China, enduring extreme cold in 
dry locations, but unable to endure the winters where the 
humidity is great. It is a tree that has been planted exten¬ 
sively throughout the drier parts of China for ornamental 
purposes. In the temple courts and burial grounds speci¬ 
mens have been found that exceed 1,000 years of age. These 
trees are of extreme size, attaining a height of fifty or sixty 
feet and from four to twelve feet in diameter. It is a tree 
that readily adapts itself to a very wide range of soil condi¬ 
tions, growing thriftily in sandy soils as well as in hard 
clay soils, and in many instances is found growing in soils 
strongly alkaline. 
It is less than twenty years ago since this tree was intro¬ 
duced into the Ignited States. It has been planted quite 
extensively throughout Southwestern Kansas and Oklahoma, 
and wherever found, it is making a splendid growth. The 
tree shows no indication of injurious effects from either the 
drought, heat or cold that has been experienced in this time. 
It is a tree that should be used extensively for woodlot, 
windbreak and ornamental planting throughout the south¬ 
western states. 
When grown in the woodlot, it should be planted closely 
so as to shade off the lower limbs and develop a straight 
clean stem that will yield poles and posts. As a post timber 
it is very durable, comparing favorably with the American 
Arbor Vitae (white cedar). 
For windbreaks, three or more parallel rows should be 
planted eight feet apart and the trees set six feet apart in 
the row, the trees in one row alternating with the trees in 
the adjacent row. In ten or twelve years these trees will 
form a solid wall of limbs and foliage from the ground to 
the height which they attain. During youth, the Chinese 
Arbor Vitae grows quite rapidly, the annual average height 
growth varying from fifteen to thirty inches per year, de¬ 
pending upon the character of the site. 
For ornamental planting care should be taken to select 
suitable specimens for this purpose, the most desirable 
being low, compact trees with dense foliage. The foliage 
of the Chinese Arbor Vitae is a deep green tliroughout the 
summer, changing to a dull brown with the approach of 
winter. The deep green is again resumed during the first 
few days of warm Aveather in the spring. 
A commendable feature of the Chinese Arbor Vitae is the 
ease with which it transplants. NurservTOcn who have 
handled it in large numbers, say that there is no more loss 
in transplanting the Chinese Arbor Vitae than there is in 
transplanting the cottonwood.—Chas. A. Scott in American 
Forestry.
