20 MISSOURI BOTANICAL GARDEN BULLETIN 
late Mr. Henry Eggert has been fully organized and more 
than 10,000 duplicates from this collection have been distrib- 
uted to the Garden’s correspondents on the basis of exchange. 
Stamping and Numbering—A system of stamping and 
consecutive numbering has been introduced; and all speci- 
mens after being mounted are stamped, by means of a com- 
bined stamp and automatic numbering machine, with a 
distinctive Garden imprint, and at the same time consecu- 
tively numbered so that an exact record is obtained of the 
number of specimens mounted each day, thereby forming an 
accurate basis for monthly reports. Plants already in the 
organized herbarium are also being similarly stamped, and 
up to the present time 41,011 sheets of this series have been 
stamped. Thus, eventually a complete inventory, as to num- 
ber of specimens in the collection, will be recorded and avail- 
able at all times. The stamped and numbered sheet greatly 
facilitates the matter of records, particularly in connection 
with the loan of herbarium specimens. 
Field Work—Pursuant to the plan for a botanical survey 
of the Southwest and for publishing eventually a flora of this 
region, Mr. Ernest J. Palmer has spent the autumn months 
collecting in the vicinity of Noel, Golden City, Galena, Bran- 
son, Williamsville and at other places in southwestern Mis- 
souri, as well as at Eureka Springs, Cotter and Moark in 
northwestern Arkansas. Although the collecting season this 
fall was unusually short, Mr. Palmer has made substan- 
tial and satisfactory progress, having secured several thou- 
sand excellent herbarium specimens, including a sufficient 
number of duplicates to enable the Garden to place a few 
sets of plants illustrating the flora of the Southwest in 
a botanical centers where they will be accessible for 
reference.
