REPORT OF THE HONORARY CURATOR OF THE ECONOMIC 
COLLECTIONS 
Dr. N. L. Brirron, Drrector-1n-CuHier. 
Sir: I have the honor to submit the following report for 
the year 1913. 
The accessions to the collections under my care number 
350 specimens. Although these specimens are of a miscel- 
laneous character, the greater majority of them pertain to the 
perfumery, drug and fiber divisions of the museum. The 
following are worthy of special note. 
A set of 63 specimens of raw materials and essential oils 
used in perfumery was donated by the Manufacturing 
Perfumers’ Association of America; our collection of aro- 
matic products, previously large, has become, by this aug-

and a bottle of oil distilled from the wood of Amyris bal- 
samtfera, from Venezuela, were donated by Messrs. Magnus 
Mabee & Reynard, of New York; a set of 8 native fiber 
plants, the fibers and some articles made of them, obtained 
in Cuba by Dr. J. A. Shafer; the fibers of Pouzolzia and 
Girardinia, from the Himalaya Mountains; the leaves and 
barks of Psychotria undata and P. Sulzneri, a native medicine 
of Florida, collected by Dr. J. K. Small; the native grapes 
of the vicinity of Salem, Indiana, donated by Mr. William 
Rudder, of that place; grapes and May-pops (Passiflora 
incarnata), collected by myself near Nashville, Tennessee. 
The large collection of general drug products of the year 
is of unusual interest and importance. Many of them 
represent spurious substitutes, to be exhibited in our cases 
beside the genuine. Among the more interesting of the 
drug specimens may be mentioned a section of the manna 
ash trunk, with the exuded manna adhering; a shrub of the 
tragacanth plant, with the exuded tragacanth adhering to it; 
a specimen of Toona gum; a specimen of the sloe berries 
used in making sloe gin; Stenolobium leaves from Mexico; 
a collection of rare native drugs from Japan, in the powdered 
state, including the roots of two species of Paeonia; several
