We are all shy on practical experience, 
PRACTICAL in fact it is one of the chief causes of 
EXPERIENCE the present disturbed conditions of the 
world. If the Kaiser had had a little 
more practical experience in war and not so much theory 
he would have used all of his power to have prevented 
it instead of planning- to bring it about. 
If we had more practical statesmen we should not 
have so many foolish impractical laws and if there were 
more practical nurserymen we should not be pestered 
with so many unsound theories that are being tried out 
as curealls. 
It seems to he an unfortunate rule that real workers 
are seldom talkers, teachers and writers. 
The man who really knows accomplishes but does not 
say much and is likely to be overlooked by the teacher as 
a source of knowledge. 
We are all interested and will usually listen to 
theories on health and sickness by anyone who is en¬ 
titled to prefix his name with Doctor, hut when we are 
real sick and it is a case of life and death, we prefer a 
man who has had much practical experience as well as 
a good education. 
A lasting impression was made on the writer as to the 
value of practical experience even without education 
and in medicine by being associated with a hospital 
nurse whose duty it was to receive all the patients 
brought to the hospital. 
Ilis prompt diagnosis was wonderful, pneumonia, ty¬ 
phoid, and other diseases wre identified at sight. When 
asked how he did it the reply was because I see so 
many, some I can tell by the smell, others by the appear¬ 
ance of the eyes and lots of ways I cannot explain. 
It is exactly the same with the plantsman, the man 
who handles plants by the thousand through the seasons 
and under vaiying conditions gains a knowledge about 
them he cannot impart to others and which the other 
fellow however well educated cannot acquire except by 
the same method. 
He seems to know instinctively the conditions which 
will bring disease and pests also the reverse, what will 
bring health and vigorous growth. 
Relief is all too general that plant diseases and pests 
are visitations to be feared. It would he far better if 
they were considered perfectly natural and the result of 
ignorance and poor culture. 
While epidemics will occur when conditions are right 
for the spread of it, there is much truth in the bull made 
by the Irish plantsman “If you keep your plants healthy 
and growing disease and bugs won’t bother em none.” 
The appointment of Edwin 
THE NEW SECRETARY T. Meredith of Iowa, to suc- 
OF AGRICULTURE. ceed D. F. Houston as Sec¬ 
retary of Agriculture gives 
the Horticulturists of the country an opportunity to rep¬ 
resent their case of quarantines and embargoes to the 
department for reconsideration, as we venture the opinion 
that Mr. Meredith might with grace give more heed to 
the requirements of the Horticultural trade than his pre¬ 
decessor. 
Reing a journalist he will be familiar with the grow¬ 
ing dissatisfaction with the arbitrary powers of the Fed¬ 
eral Horticultural Roard. 
COOPERATION RETWEEN SCIENTIFIC 
HORTICULTURISTS AND NURSERYMEN 
Read before the S. D. Ilort. Society, January 20, 1920, by 
Max Pfaender, with the Gurney Seed and Nursery 
Co., Yankton, S. D., formerly horticulturist at 
the Northern Great Plains Field Station, 
Mandan, N. D. 
T HE title of this paper no doubt, at once, calls atten¬ 
tion to the fact that the speaker assumes the exis¬ 
tence of these two distinct classes of horticultur¬ 
ists, namely: the scientific horticulturists and the nur¬ 
serymen. There are, of course, other classes which af¬ 
fect the horticulture of a state, section or country but I 
have chosen these two for my discussion as I am most 
familiar with the aims, work and results of these two 
particular groups. And no doubt these two play, by far, 
the most important part in the development of a better 
horticulture of any state, section or country. 
I believe that these two groups are more or less organ¬ 
ized into state, sectional or national associations or so¬ 
cieties. Rut it has also been deeply impressed upon me 
in my career, both as an experimentalist, or scientific 
horticultural investigator and as a practical nurseryman, 
that there has not been that cooperation between these 
two groups which would produce the greatest possible 
results for the public. Each group has followed its own 
destiny, each ignoring the other’s existence. 
The scientific horticulturists in many cases have con¬ 
fused the real nurseryman with the proverbial tree ped¬ 
dler and have therefore, very illogically however, 
stamped all nurserymen as profiteers, grafters or swind¬ 
lers. 
On the other hand the nurserymen have likewise un-
