THE NATIONAL NURSERYMAN 
APPLK HUD SELUCTION AND APPLE SEEDLINGS 
EHOM SELECTED TREES 
C. S. Crandall, Illinois Experiment Slatioii. 
In (‘oiinection willi apple l)ree(ling' investigations 
started in 1907 a minor projeet in biul seleetion was un¬ 
dertaken to determine whether or not there are differ- 
enees in value for tlie purposes of propagation hetween 
large l)nds and small hints, hetween huds jiroduced on 
ditiereid i)arts of the tree, and hetween hints from differ- 
('nt locations on the shoot. Another projeet undertaken 
at this time consisted in growing a})ple seedlings from 
fruits from trees chosen as ])ossessing special merit. 
This hulletin brings together the records thus far made 
in comu'ction with these jirojeets, presents the methods 
juirsued, and gives the status of the trees growing under 
('aeh of the projects. 
Summing uj) the data relative to size and position of 
huds us('d for propagating, it is eoneluded that there are 
no differences for this purpose hetween huds of large size 
and those of small size. Growdh curves of trees propa¬ 
gated from huds from different situations on the trees so 
closely approximate as to indicate that it does not matter 
from what situation on the tree the huds are taken. All 
huds from healthy shoots are of equal value for })ur- 
poses of ])ropagation, at least so far as growth of trees 
is concerned. 
There were decided and often extreme fluctuations in 
growth of individual trees within jiarticular groups. In 
general, differences became less with increase in age. 
provided the trees remained healthy. No marked differ¬ 
ence was observed in the growth of trees ])roi)agated from 
robust scions and those propagated from scions of small 
diameter. Studies of annual increments support and em¬ 
phasize the fact of distinct individuality in the giowtli of 
trees. 
The apple seedlings grown from fruit from selected 
trees have not come into bearing thus far. Observations 
and data secured relative to the growth of these seed¬ 
lings, however, indicate that seedlings from seeds of 
large fruits are somewdiat more resistant to adverse con¬ 
ditions and possess a higher degree of vitality than do 
seedlings from weeds of small fruits.

QUARANTINE ON ACCOUNT OF RLACK STEM RUST 
Notice of Quarantine No. 38. 
{Effective on and after May 1, 1919.) 
The fact has been determined by the Secretary of Agri¬ 
culture, and notice is hereby given, that the common bar¬ 
berry (Rerheris vulgaris') and its horticultural varieties, 
as well as other species of Rerheris and Mahonia. are 
capable of harboring the black stem rust of wheat, oats, 
barley, rye, and many wild and cultivated grasses. 
Through the co-operation of the Department of Agricul¬ 
ture with State officials, local organizations, and indiv¬ 
iduals, susceptible species of barberry and Mahonia have 
been veiy largely eradicated from the States of Nebraska. 
Iowa, Illinois, Indiana, Ohio. North Dakota. South Da¬ 
kota, Minnesota. Montana, Wisconsin. Michigan. Wyom¬ 
ing. and Colorado. 
Now, therefore. I, David F. Houston, Secretary of Ag¬ 
riculture, under the authority conferred by Section 8 of 
the Plant Quarantine Act of August 20. 1912 (87 Stat.. 
SIS'), as amended hy the Act of Congress approved March 
4, 1917 (39 Stat., 1134, 1165), do hereby quarantine, ef¬ 
fective May 1, 1919. the States of Alabama, Arizona. Ar¬ 
kansas, California, Connecticut. Delaware, Idorida.
