Ilia. Corn, calf, and pig clubs were established and a beginning 

 made looking toward organizing farm bureaus for the leading agri- 

 cultural-sections of the islands. The work of the various collabora- 

 tors was continued and many localities are being reached in this way. 

 During the year an extension agent was appointed for the island of 

 Hawaii. 



The cooperative work with the Territorial Food Commission was 

 highly successful and the relations were very satisfactory. The work 

 carried on in cooperation with the War Department at Schofield Bar- 

 racks Avas continued and considerably extended, and plans- were ma- 

 tured for extensive plantings of forage and other crops suited to the 

 locality. The cooperation maintained between the station and the 

 Territory at the Glenwood station on Hawaii was terminated by 

 failure of the legislature to continue the approi^riation which had 

 been made for about six years. Provision was made for continuing 

 the work for a time on a collaborator basis. 



The Territorial marketing division, established by the station in 

 1913 and wholly taken over b^ the Territory in 1017, was intended 

 to provide a means for the disposal of small quantities of produce 

 and thus foster diversified agriculture. The amount of business of 

 the market increased so rapidly that it was selling about $20,000 

 worth of island produce a month. Later the retail privilege was 

 withdrawn, and the legislature at its "' f -^^^sion did not continue the 

 appropriation for its maintenance. 



POUTO RICO STATION. 



D. W. May continued as loc.d agent in charge of this station. The 

 work of the station during the year was directed mainl}^ along two 

 lines, investigation and extension. The investigational work was in 

 continuation of projects that have been in progress for some 3^ears. 

 The extension work was carried on through demonstrations, meetings, 

 and the distribution of seeds and plants, literature, etc. One of the 

 important lines of investigation was in connection witli the mottled 

 leaf disease of sugar cane. This disease has spread rather widely and 

 threatens to curtail sugar production. The station cooperated witli 

 the department in making a study of insects as carriers of the dis- 

 ease, the cause of wiiich is as yet unlaiown. The question of varietal 

 resistance has been given especial attention. Several years ago the 

 station introduced a considerable number of varieties of sugar cane 

 i'rom other tropical countries and among them are several which 

 bhow more or less resistance to the disease. Effort'j are being made 

 to increase seed cane of one of these varieties as rapidly as possible 

 for planting in the infected portions of the island. As a result of 

 the station's investigations on vanilla a number of commercial plant- 

 ings, ranging from 1 to 10 acres in extent, have been made. Studies 

 were continued on some of the problems relating to the preparation 

 and marketing of the crop. 



The rice work, begun a year ago in cooperation with the Office of 

 Cereal Investigations, has yielded promising results. Nursery and 

 other plants have been planted at the station and about 130 acres wei'C 

 sown in field trials carried on by the station and growers in various
