nient Station Record, reports the progress 

 made at this institution in the development 

 and extension of its agricultural work. One 

 of the events was the organization, late in 

 1918, of an agricultural experiment station. 

 This action followed a recommendation by 

 Professor C. "W. Woodworth of the California 

 University and Station, who was then tem- 

 porarily serving at the college as special in- 

 vestigator and lecturer on entomology. Sub- 

 sequently, several tracts of land, aggregating 

 about 21 acres, were purchased at a cost of 

 $9,000. About 5 acres have already been 

 planted to mulberries for sericultural work, 

 and the remainder is imder general cultiva- 

 tion. The college also has the use of about 

 36 acres of vacant university land, though the 

 small size and scattered nature of the various 

 holdings constitute a serious handicap to ex- 

 perimental work. It is estimated that eventu- 

 ally at least 160 acres of adjacent land will be 

 needed for the college farm and station. 



Much of the principal work so far under 

 way has dealt with sericulture. About $5,000 

 has been provided for this by the International 

 Committee for the Improvement of Sericul- 

 ture in China. The chief undertaking of the 

 committee is to produce certified silk worm 

 eggs by the Pasteur process and distribute 

 them to farmers, studies at the college in- 

 dicating an average incidence of disease of 66 

 per cent, for uncertified stock. This work 

 was temporarily interrupted by fire, which 

 destroyed the entire product for the year. 

 The college is also grafting 100,000 mulberry 

 trees for sale at cost in 1921 and 150,000 for 

 1922, and is carrying on experiments in the 

 production of mulberry cuttings and studies 

 in pruning, fertilization, culture, etc. Tests 

 are being made on the utilization of the 

 autumn crop of mulberry leaves, as well as 

 breeding and selection work with silk worms. 

 A three-month course in sericulture has been 

 instituted, and extension work through lec- 

 tures and demonstrations is contemplated. 



Cotton experiments have already shown that 

 certain foreign varieties can be successfully 

 grown in China, though careful tests are 

 necessary to determine the adaptability of 



varieties to diverse conditions. A cooperative 

 test was organized in 1918 in eight provinces 

 with pure seed of the standard test sets of 

 the U. S. Department of Agriculture. The 

 cotton improvement work is being supported 

 by two Chinese cotton mill owners' associa- 

 tions and the Shanghai Anti-Adulteration 

 Association. 



Improvement of native corn by pedigree 

 selection has been carried on for four years, 

 and seed distribution to farmers is to be 

 begun this spring. There has also been 

 selection work with about 75 strains of low- 

 land rice, 100 native and foreign strains of 

 wheat, and about 100 varieties of fruits. 



There is much interest in forestry, and 

 about 7 acres of land are devoted to forest 

 nurseries. A colonization project on Purple 

 Mountain has, largely developed into a re- 

 forestation demonstration. 



The student enrollment has numbered about 

 100, of whom 42 were regular students in 

 agriculture, 30 in forestry, and 26 in the short 

 course of sericulture. The demand for trained 

 graduates has exceeded the supply, notably 

 for assistants for agricultural missionary 

 work. There has been a marked increase in 

 interest on the part of missionary organiza- 

 tions and also by a number of influential gov- 

 ernment officials. 



ALL-AMERICAN CONFERENCE ON VENEREAL 

 DISEASES 



An All- American Conference on Venereal 



Diseases will be held in Washington, D. C, 



December 6 to 11, 1920. It is under the 



auspices of four organizations — 



The U. S. Interdepartmental Social Hygiene 

 B'oard, represented by its executive secretary, 

 Dr. Thos. H. Storey. 



The TJ. S. Public Health Service, represented by 

 Assistant Surgeon General C. C. Pierce. 



The American Bed Cross, represented by its presi- 

 dent, Dr. Livingston Farrand, and 



The American Social Hygiene Ass'n., represented 

 by general director, Dr. Wm. F. Snow. 



The conference will deal with both admin- 

 istrative and research problems, and will con- 

 sider the attack on venereal diseases from four 

 different aspects:
