a CHESTNUT TREE BLIGHT. 5 
(a) The determining of the exact range of the disease, and the 
locating and cutting out of all advance infections. This work to be 
done in Virginia, West Virginia, western and probably southern Mary- 
land, Ohio, western Pennsylvania, central and western New Yorks 
possibly also in Kentucky, Tennessee, and North Carolina, followin, 
the methods now employed by the Chestnut Blight Commission o 
Pennsylvania. In all localities, and particularly in those States 
where no State quarantine of any sort is contemplated, it will be 
necessary to instruct private owners regarding the disease m order 
that they may take such measures as they see fit to protect their own 
ea en : 
(6) The careful inspection of all nurseries containing chestnut 
trees, and all chestnut nursery stock. 
(c) Determining by extensive local investigation the best methods 
of rapidly utilizing and marketing the timber of trees dying and dead 
from this disease, in order to protect timber owners against total 
loss, and to reduce infection. This work to be done in all localities 
where infection is already general. 
(d) Detoraming what changes in general forest management are 
necessary in, those localities where the chestnut tree is already doomed, 
and so far as practicable putting such changes immediately into 
practice. 
(e) Continuing experiments on tree surgéry and tree medication, 
in the hope of saving valuable orchard and ornamental trees. Any 
positive results from this line of work will also be applicable to other 
tree diseases, including those of fruit trees. 
(f) Continuing search for a resistant American stock, and breeding 
from resistant Asiatic stock, in order particularly to rehabilitate the 
chestnut-orchard industry; at the same time breeding also for timber 
trees. Results of the greatest value to the chestnut-orchard industry 
can, not fail to be secured from this line of work. 
(g) Making careful studies of the many unsolved scientific problems 
involved in the disease. Some of the more important of these are: 
The relation of the disease to climate; the relation of the parasite to 
the varying tannin, content of the tree; the origin of the disease; the 
relation of birds and insects to the distribution of the disease; the 
nature and degree of resistance in the Asiatic varieties. 
(h) Determining in detail the relation of the disease to the future 
of the chestnut timber in the proposed Appalachian Forest Reserves, 
and making special effort to keep the disease out of this territory. 
With the exception of about $400, expended by the Forest Service 
in 1908 in the work set forth in the inclosed circular Pe R. Hodson, 
all expenditures have been made in the Bureau of Plant Industry. 
The amount thus far expended in this study and investigation 1s 
$14,885.96 (estimated), which is itemized as follows:
