Program: Dr. W. A. Orton: Physiatric botany (illustrated). The 
history of diet is divided into three periods, ancient, medieval, and 
modern. The medieval period is the one of the chemical view of foods. 
The modern is the Biological Period. It began about 1900 with the recogni- 
tion of the importance of vitamines. Vegetables are important in the diet. 
Especially is this true in the cases of diabetes, nephritis, and other similar 
diseases. Many kinds of vegetables are available to furnish adequate variety 
to the diet. 
Dr. F. E. Kempton: Barberry eradication in the United States. Barberry 
eradication began in Europe in 1795. Satisfactory results were obtained. 
The American wheat rust epidemics of 1904 and 1916 awakened interest in 
the subject and active work began with the passing of the South Dakota 
anti-barberry law in 1917. The present campaign for barberry eradication 
was begun in April 1918. A preliminary campaign of education and survey 
was organized, and the field work was begun about April of that year. Con- 
gress appropriated in 1918, $150,000 for barberry eradication. Since that 
time eradication has been conducted in cooperation with each of the following 
13 states: Colorado, Illinois, Indiana, Iowa, Michigan, Minnesota, Montana, 
Nebraska, North Dakota, Ohio, South Dakota, Wisconsin, and Wyoming. 
A federal quarantine was placed, effective May 1, 1919, prohibiting the move- 
ment into the eradication area of any barberries known to harbor the black 
stem rust of wheat and other grains. A much larger appropriation of 
$350,000 became available July 1, 1922, under which marked progress has 
been made during the field season of 1922. During the five years, 1918-1922, 
practically all cities and villages of the 12 states have been covered once and 
resurveyed in part, and 472 counties have been completely covered. This 
includes 39 counties surveyed on funds furnished by states. In the 5 years, 
2,069,017 bushes have been found in cities and villages and 3,740,351 on 
farms, making a grand total of 5,829,368 bushes found, of which 5,173,547 
have been removed.

SCIENTIFIC NOTES AND NEWS 
The National Geographic Society announces a series of Contributed 
Technical Papers embodying the scientific results of its expeditions. The 
first number entitled “‘The origin and mode of emplacement of the great tuff 
deposit of the Valley of Ten Thousand Smokes,” by C. N. FENN=ER of the Geo- 
physical Laboratory, which cooperated with the Geographic Society in the 
Katmai Expedition, is now ready. 
Dr. FENNER’s paper gives details of the hot sandflow not included in the 
nontechnical volume, “The Valley of Ten Thousand Smokes,’’ by the director 
of the expedition, Ropertr F. Griaes, recently published by the National 
Geographic Society. Wan 
This series of papers from time to time will embody researches in diverse 
fields of science resulting from National Geographic Society expeditions. 
Notices of their appearance will be sent to all who desire such notification. 
The papers themselves will be distributed only to those who specificially 
request them. 
The Board of Managers of the Washington Academy of Sciences has elected 
the following scientists to honorary foreign membership in recognition of 
their prominence in their respective fields and their intimate connection with 
scientific work in Washington:
