the work can best be done and how It may be done to 
the best advantage. The. problems involved are so com- 
plex that private interests can not well handle them. 
Briefly then, the chief problems connected with 
the production of commercial stocks of apple, pear, 
plum, cherry, and rose are to find regions and soils 
in this country where such stocks may be commercially 
grown and to demonstrate on a commercial scale that 
such stocks are equal to - or better than -those grown 
abroad. We use the word "commercial" here in the sense 
that the procedure throughout should be such that the 
results secured may be satisfactorily applied by the 
trade. Such work as is proposed will need the help 
and cooperation of the trade. Nurserymen have not 
been idle in the past in this field. As recently 
pointed out by Mr. Wm. Pitkin and others, nurserymen 
have tried for years to develop the business of pro- 
ducing fruit tree seedlings but, With the exception 
of the apple, no material progress has been made. It 
has been further pointed out that many nurserymen 
prefer to import French apple seedlings and pay more 
for them, believing that thereby they would secure 
better blocks of better trees. 
Correlated with the problem of commercial stock 
production, is that of securing seeds for stocks. 
There are no contemplated restrictions, so far as we 
are aware, on the importation of fruit seeds. The re- 
strictions brought about by war conditions, and the 
general situation with respect to seed for stocks, 
show the need for developing our own home supplies. 
This is a long time proposition, as there are few rec- 
onized sources of supply here, such as exist in Europe.
