THE NATIONAL NURSERYMAN

destroys the chestnut trees and may be found on any 
species of poplars or cottonwoods. 
Trees attacked hy this fungus show cankers or de¬ 
pressed areas in the hark, these spread rapidly and often 
girdle the twig, limb, or trunk of the tree killing the part 
above the canker; the trees become ragged in appearance 
and finally die. This is especially true of the Lombardy 
poplars so often planted in rows along highways. 
The fungus which causes this disease, according to the 
authorities, was imported from Europe and is especially 
severe on stored and transplanted nursery stock. The 
centers of infection appear to he. in every case, either 
certain nurseries known to contain diseased trees, or 
points where poplars from such nurseries have been 
planted. 
Residents of New York who think their trees are af¬ 
fected by this disease, may receive exact information by 
sending samples to the department of plant pathology, 
New York State College of Agriculture, Ithaca, New York.

Dear Sir:— 
Since advertising in the National Nurseryman 
we have had so many calls for nut trees and the 
sales have been so good that we are now almost 
entirely sold out and for that reason we find it 
advisable to discontinue our advertising at pres¬ 
ent. Generally I do not believe it good policy to 
quit advertising even after one is sold out but we 
are moving our nursery operations from Indiana 
to Bowie, Maryland, and for that reason do not 
have very much of an idea how many trees we 
will have to put on the market next fall. If we 
were sure that we would have a good fall stock 
we would carry the ads. and try to get the in¬ 
quirers to let us book their orders but I very 
much doubt whether it would be very good bus¬ 
iness policy to do that with the uncertainty of 
trees to fill the orders next fall. 
We have been very much pleased and sur¬ 
prised at the result from advertising and also at 
the growing demand for nut trees throughout the 
country. It shows that the public are beginning 
to realize the advantage of setting nut trees for 
shade and ornamental purposes instead of the 
numerous worthless trees that have been so gen¬ 
erally used heretofore. 
Please send me bill for our advertising account 
if we owe you, and I shall take pleasure in mail¬ 
ing you a check in payment of same. 
Very truly yours, 
T. P. Littlepage. 
Review, rtote Comment. 
This is news. Owing to the rapid increase of the bus¬ 
iness the St. Cloud Nursery Co., St. Cloud, Minnesot-i, 
built last summer one of the nicest Retail packing plants 
in the Northwest, and will be able to pack their stock so 
that it will reach their customers in the very best of con¬ 
dition. 
ADDITIONAL APPOINTMENTS TO THE ADVISORY 
BOARD OF THE NATIONAL ASSOCIATION 
William Flemer, Springfield, N. ,T., representing the 
New Jersey Nurserymen’s Association. 
Robert Bagby, New Haven, Missouri, representing the 
Missouri State Nurserymen’s Association. 
Edward Moon, William 11. Moon Co., Morrisville, Pa., 
representing the Wholesale Growers Association. 
The labor situation looks very much as if the nur¬ 
series would have to draw on their office forces to help 
out in the digging and packing and that the boss him¬ 
self would have to take off his coat, and roll up his 
sleeves, even if he is not in the habit of doing so. 
NATIONAL ROSE AND PEONY GARDENS 
Department of Agriculture Assemblings Collections 
of the Flowers in Washington^ D. C. — Contri¬ 
butions Requested. 
Flower lovers are being asked by the Office of Horti¬ 
cultural Investigations of the U. S. Department of Agri¬ 
culture to contribute to the test gardens at Arlington, 
Virginia, just across the Potomac from Washington, 
roses and peonies of varieties not now represented in the 
Government collections. It is the hope of the Department 
to assemble at the Arlington gardens as nearly complete 
collections of varieties of the two flowers as possible. 
These collections will be used for comparison and study 
of conditions under which they thrive best, and also as a 
basis for plant breeding work. At the present time ap¬ 
proximately 700 varieties of roses and 400 varieties of 
peonies are growing in the Arlington gardens. These 
represent about one-half the varieties of each of the 
flowers believed to exist in the United States. 
The Department of Agriculture is creating the test 
gardens in cooperation with the American Rose Society 
and the American Peony Society. The rose garden was 
begun in 1915. The peony collection was started last fall. 
The majority of the plants have been contributed by nur¬ 
serymen and florists, though many have been given by 
amateurs. Express or postal charges are paid by the con¬ 
tributors. Plants should he sent during the dormant 
season, which lasts from fall to late April. Potted plants 
may be sent successfully as late as the last of May. 
Persons who believe they have varieties of roses or 
peonies not represented in the Arlington gardens and who 
wish to contribute to the collections should first write to 
the Office of Horticultural investigations. Washington, D. 
C., offering specific varieties or requesting a list of the 
varieties desired.
