nia. Com, calf, and pig clubs were establislied and a beginning 

 made looking toward organizing farm bnreans 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 wa}'-. 

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

 IlaAvaii. 



The cooperative work with the Territorial Food Commission was 

 liighl}' successful and the relations were very satisfactory. The work 

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

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

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

 localit}'. 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 appropriation which had 

 been made for about six ^ears. 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 1917, was intended 

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

 ancl 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 withdrawn, and the legislature at its last session did not continue the 

 appropriation for its maintenance, 



rOICTO EICO STATION. 



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

 work of the station during the yeav was directed mainly along two 

 lines, investigation and extension. The investigational work was in 

 continuation of projects that have been in progress for some years. 

 The extension work was carried on thi-ough demonstrations, meetings, 

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

 important lines of investigation was in connection with the mottled 

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

 threatens to curtail sugar production. The station cooperated with 

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

 ease, the cause of which is as yet unknown. The question of varietal 

 resistance has been given especial attention. Several years ago the 

 station introduced a considerable number of varieties of sugar cane 

 from other tropical countries and among them are several wliicli 

 shovf more or less resistance to the disease. Effort;; 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 Avork, begun a year ago in cooperation with the OfRce of 

 Cereal Investigations, has yielded promising results. Nursery and 

 other plants have been planted at the station and about 130 acres were 

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