Soc, 2. DISEASES FORMERLY MENTIONED IN QUARANTINES. 
In addition to the diseases and pathogens named in 
quarantines emd regulations as now worded there are eight pathogens 
mentioned in quarantines which have since been rescinded or super- 
seded in whole or in part, so the name of the disease or pathogen no 
longer occurs in our quarantines. Quarantine No. 1 was based on 
white pine blister rust (Peridermium strobi ) but entry of the hosts 
of this disease is now governed by the restrictions of Quarantine 
No. 37 in which the pests concerned are not mentioned. With the 
rescinding of Quarantine No. i4i the entry of oriental fruit stocks 
was placed under the provisions of Quarantine No. 57 also, eliminating 
5 pathogens from the list of those mentioned in the quarantines 
remaining in effect, viz., Valsa mali , Diaporthe mali , Taphrina piri , 
Gymnosporangtim koreaense (now G. haraeanum ) , and ^. photiniae (now 
G. japonioum ) . The powdery sc^b of potatoes ( Spongospora subterranea ) 
was found to be more or less prevalent in the United States and doing 
relatively little daioage so Quarantine No. 11, based on this disease, 
was rescinded. Quarantine No. 39 'fas based in part on take-all 
(Ophiobolus graminis ) but it also was found to be widely distributed 
in the United States and Canada and was omitted when Quarantine No. 
59 was issued superseding Quarantine No. 39» 
Sec. 3. DISEASES MENTIONED IN ADMINISTRATIVE ORDERS FOR THE 
INSPECTION HOUSE. 
In addition to foreign plemt diseases and pathogens men- 
tioned in the quarantines and regulations a few were named in 
administrative orders to inspectors at the Washington Inspection House. 
All Solanaceous material (particularly of Solanum and 
Lyoopersicum ) from Central or South America was to be grown in 
quarantine because of the danger of introducing Puccinia pittieriana 
which was not knovm to occvir in North America at the time. Dahlias 
and packing from Europe were to be examined with care for the possible 
presence of leaf or stem fragments that might carry the leetf smut, 
Entyloma calendulae. Orchids from Evirope were to be examined for the 
possible presence of rusts (Hemileia spp.). Pineapple slips from 
Central and South America were to be grown in quarantine because of 
the presence in Costa Rica and possibly other parts of Central America 
of a rotting disease, the cause of which was unknovra. All Departmental 
importations of peanut, Arachis hypogaea , arriving from Java and other 
parts of the Orient were to be grown in detention because of the 
presence in Java and probably other Oriental countries of a mosaic and 
other diseases which may be transmitted in the seed.
