REPORT OF THE HONORARY CURATOR OF THE 
CONOMIC COLLECTIONS 
Dr. N. L. Brrrron, Drrecror-1n-CHieEr. 
Sir: I have the honor of submitting the following report 
on the economic collections for the year 1919. 
All specimens in the economic museum are systemati- 
cally arranged in the cases, and a complete list of them has 
been written, the last pages of which are now being typed. 
This work has occupied my entire spare time during the 
past year. It has been found much more extensive than 
was anticipated, owing to the fact that many omissions 
were discovered, the missing articles being of such im- 
portance that it was deemed undesirable to print a cata- 
logue in which they were not enumerated. To secure these 
specimens has required the expenditure of much time and 
labor. Many have been donated in response to requests 
and many others secured through purchase by myself. 
Others have been specially collected for us by friends and a 
much larger number by myself. Of the latter, many were 
grown in my garden for this purpose. The total number 
of such specimens amounts to several hundred. 
Besides these actual additions to our collections, the 
cases have been enriched by the installation of several 
hundred specimens which had been in storage, awaiting the 
necessary supply of containers. 
As a result of these changes, nearly all of the two large 
lots of jars supplied me during the year have been filled 
and we are already in urgent need of a farther supply, 
especially of the smaller sizes and of some extra large ones. 
Many hundreds of base-blocks will also be required to 
complete the mounting of the jars. 
Another result of the year’s growth has been that of
