Iyxperiments with Nursery Stock. 

At the request and through the co-operation of this Station and 
a large number of nurserymen of Western New York, a series of. 
experiments with nursery stock was undertaken at this Station in 
1891 by the Division of Vegetable Pathology of the United States 
Department of Agriculture. The work was carried on by D. G. 
Fairchild, Assistant Pathologist. A ‘brief report of this work was 
published in the Tenth Annual Report of this Station, 1892, pp. 
179-181. A more complete account of this work for 1891 and 1892 
is given below by Mr. Fairchild, together with a brief report of the 
work in co-operation with the Station Horticulturist in testing 
different fungicides as to their efficiency in preventing the leaf 
blight of pear seedlings. 
EXPERIMENTS IN PREVENTING LEAF DISEASES OF NUR- 
SERY STOCK IN WESTERN NEW YORK.* 
By D. G. Farrcuixp. 
[Plates 20-28. ] 
It is the intention to give in the following paper a brief account 
of experiments made during the seasons of 1891 and 1892 with a 
view of preventing the various leaf diseases of nursery stock. 
These experiments were carried on atti Geneva, N. Y., one of the 
largest nursery centers east of the Mississippi. The kindness of 
Dr. Collier, director of ‘the New York State Agricultural Experi- 
ment Station, made it possible for the work to be done upon the 
Station grounds, where proximity to the laboratories and assist 
ance from the Station staff greatly facilitated the work. 
To bring together in one article the results of the experiments, 
it will be necessary to repeat in part matter that has previo 
been published.§
