In the adjustment that 
NON-ESSENTIAL BUSINESS is taking place while 
the country is mobiliz¬ 
ing its resources for the purpose of war, the nur¬ 
sery business is sure to sutler like all others that have 
to stand aside until the forces.for destruction have been 
organized. 
We hear and read a great deal about non-essential bus¬ 
iness. This is an unfortunate phrase at the best, as all 
business is essential, except that which has a tendency to 
degrade humanity. 
Agriculture, horticulture and floriculture are funda¬ 
mental and essential to our civilization, and must be car¬ 
ried on to the utmost detail, wherever and whenever war 
permits. It is up to the nurseryman to preserve his part 
of our economic structure during this crisis of the 
world’s history, and not to let the invasion of the Hun 
cause his profession to slip hack any more than is 
jiossihle. It is true he will have to fight hard, but so do 
the men at the front. What greater disaster could 
happen to a victorious army returning to their homes 
than to find the orchards run wild, the lawns around the 
homes turned into weed patches and the beauty spots that 
look years of art and labor to produce, neglected and 
spoiled. 
There has been enough such destruction in Belgium and 
Fronce. There is labor and funds enough in the United 
Slates to keep things going as well as to build ships and 
lick the Hun, and it is up to the nurseryman to hold his 
part of the line until reinforcements return. 
The editor of the National Nurseiyman, takes this op¬ 
portunity to express his appreciation to President J. R. 
Mayhew, for his action in offering and supporting a mo¬ 
tion at the Chicago Convention of Nurserymen to permit 
the representatives of the Nursery Trade Journals to re¬ 
main in the convention hall throughout all of the sessions, 
so that an accurate report of the proceedings might he 
juinted. 
The National Nurseryman has always su])ported the 
Association and its officers in its various aims, and this 
action of the Association will go far in creating an in¬ 
creased interest by nurserymen in its work, and should 
result in materially increasing its membership. 
Now, if the Executive Committee could see their way 
clear to authorize and direct Counsel Smith to keep the 
Nursery Trade Journals informed of so much of the 
work of his office which might be of general interest, 
without disclosing matters of a confidential character, it 
would still further benefit the good work of the Associa¬ 
tion. 
WHEAT RUST AND THE COMMON BARBERRY 
Prof. Whetzel of Cornell University is chairman of a 
committee engaged in the wheat rust problem, and has 
sent out a leaflet giving information on this subject. 
The very destructive stem rust of oats, wheat, rye, 
etc., including some of the wild grasses, is caused by a 
fungus {Puccinia, graminis) which passes one stage of 
its life on Barberry leaves or fruit. The Barberry be¬ 
comes infested in the spring from the Black Rust spores, 
which over-winter on the stalks of the cereal or grass 
hosts. 
In the Southern States the rust winters on living 
leaves of the over-wintering grain or grasses, so the 
Barberry is not always necessary to perpetu£^te the rust. 
However, the Barberry’s importance in starting the rust 
off early in the season is well established. In Denmark 
the eradication of the Barberry has almost entirely elim¬ 
inated the stem rust. 
It is only the common Barberry {Berberis vulgaris), 
and its horticultural varieties such as the purple-leaved 
one that are affected by the stem rust, Berberis Tfiun- 
bergii being immune. 
Nurserymen should stop growing the Berberis vul¬ 
garis and disseminating it. Landscape gardeners should 
cease to specify it on their plans or have it planted. 
Prof. Whetzel advocates it being rooted out wherever 
there is a possibility of it proving a host in the vicinity 
of grain crops, and asks that specimens of the common 
Barberry be sent to the Department of plant Pathology, 
Ithica, N. Y., for examination wherever there is a sus¬ 
picion that they are infected by rust. 
Senator Orlando Harrison, of the Harrison Nur¬ 
series, Berlin, Md., made the dedication address on Far¬ 
mer’s Day at the Maryland State College of Agriculture. 
It is the life work of such men as Mr. Harrison that 
does so much to prove the nurseryman’s value to the 
welfare of the State. 
Mr. Harrison has been the means of getting appropria¬ 
tions necessary for the building of the college buildings 
dedicated to the cause of agriculture, and it brings it 
home to everyone how fundamental and essential the 
nurseryman is, along with the farmer, to our very exis¬ 
tence.
