B. E. P. Q. 461. 
PRESENT STATUS OF THE CIRCULARS OF THIS (B. E. P. Q) SERIES 
August 31, 1937. 
Commencing January 18, 1915, circulars containing official Federal plant quar- 
antine information have been issued from time to time in a numbered series. 
This series has been designated by "H. B.", "P. Q. C. A.", "B. P. Q.", and "B. E. 
P. Q." as prefixes to the numerals, and these designations referred to the Federal 
Horticultural Board, Plant Quarantine and Control Administration, Bureau of 
Plant Quarantine, and Bureau of Entomology and Plant Quarantine, respectively. 
Many of the circulars contained information or instructions of transitory 
importance only ; others were superseded by later circulars ; in many instances 
changes in, or revocation of, quarantines rendered them of interest only as a 
record of Bureau activities ; while in still other instances changes in procedure, 
technique, or other conditions have made them obsolete insofar as present prac- 
tice is concerned. 
The purpose of this circular is to indicate which of these preceding circulars 
are valid and which are obsolete. A circular may be herein indicated as obso- 
lete insofar as its present status is concerned, although it may contain informa- 
tive material that is still useful. For that reason inspectors and others en- 
gaged, or interested, in plant-quarantine work will wish to place the obsolete 
circulars in an inactive file, available for reference if occasion arises.
