41. In Portugal and France, a method of placing a wire around 
young coppice shoots in the early part of the season and of moun- 
ding earth and humus material around the shoots has given good 
rooting by fall. Propagation by leaf bud cuttings under continuous 
mist has given very limited success in the United States and is 
being further tested. Extensive tests of propagation of Asiatic 
chestnuts by root and twig cuttings have in general. resulted in 
failure even when various root-inducing chemicals are used. 
42. One of the most rapid methods of increasing a variety or 
clone, now in use in Italy and elsewhere, is to top work Asiatic 
chestnut on vigorously growing European chestnuts 2 or 3 inches 
in diameter. Frequently a very large quantity of the Asiatic chestnut 
or its hybrid is produced in one year of growth. Of course, in an 
area where blight is present, the disease has a tendency to develop 
very quickly in the wounds. In fact, in all nursery operations it 
is necessary to take precautions against the blight organism getting 
into wounds, because even with resistant selections the fungus 
will frequently kill the material before the scion starts to grow. 
43. In Italy, limited success has been obtained by grafting 
scions of Asiatic chestnut on European chestnuts cut off at or near 
the ground level. Precautions are taken to prevent the blight getting 
into the scions or stock in the operations, and then the earth is 
mounded up around the base of stock plants. In nature, chestnut 
blight usually extends only a short distance below the ground 
level. If the roots of susceptible trees are exposed to light by 
erosion, the blight will develop on them abundantly. 
44, Some methods of chestnut propagation are briefly mentioned 
because it. is felt that the subject should receive further attention 
from the various countries interested in growing Asiatic chestnuts. 
There are a sufficient number of individuals interested in Asiatic 
chestnut propagation to work out in detail the very best methods 
of handling these chestnuts under different conditions. 
45. However, to secure this desirable result it is necessary 
that experiments be more carefully planned and that better records 
be kept on the stock and scion material and the various conditions 
of the experiment. It is very important that the best clones or horti- 
cultural varieties of Asiatic chestnuts and their hybrids, as 
developed in Europe, be adequately tested in carefully planned 
experiments so that all countries concerned can benefit more from 
the respective work done in the different countries. Planning and
