campaign it is reported that the area devoted to food crops was in- 

 creased by 43 per cent. Large areas usually devoted to a second 

 tobacco crop were planted to corn and beans. It is estimated that 

 more than 25,000 domestic gardens were planted during the year. 

 Cooperative work in rice growing has been begun, about 60 acres 

 being grown in different parts of the island to determine the possi- 

 bility of developing this industry. Porto Rico imports about $5,000,- 

 000 worth of rice annually, and it is believed that at least half of 

 this amount could be locally produced. An experiment in winter 

 production of garden seeds was begun, but the work was inaugu- 

 rated so late in the season that no definite results were obtained. In 

 cooperation with the Bureau of Chemistry of this department, ex- 

 periments on the utilization of citrus by-products were undertaken 

 with such successful results that a cooperative organization has been 

 formed to manufacture them on a commercial scale. 



GUAM STATION. 



The Guam station reported satisfactory progress during the year. 

 It assisted in inaugurating the first industrial fair held on the island, 

 this proving a success in every respect. Exhibits of stock and agri- 

 cultural products were made by_ the station to show the superiority 

 of improved live stock and new and better food crops. Such ex- 

 hibits are believed to have an educational value and, by stimulating 

 interest in the station's work, to bring about an improvement in 

 the general condition of the people. This fair was held early in the 

 fiscal year, and as one of its results there were more requests on the 

 station for seeds and plants than ever before. During the past year 

 more than 50,000 plants, 7,182 lots of vegetable seed, 59 pounds of 

 leguminous cover-crop seeds, 251 sacks of grass roots for planting, 

 and a larger number of kafir heads were distributed in the island. 

 Guam is so situated that the station is about the only source of seeds 

 and plants, and through a cooperative arrangement with the insular 

 government directions are given for planting and supervision of 

 the crops is maintained. Through this means the efforts of the local 

 government for greater food production have been aided. Many 

 farmers in Guam are beginning to save their own seed, being aided 

 and advised by the station in supplying their necessities in this line 

 as far as possible. 



The work with the live stock progressed very satisfactorily. On 

 September 27, 1917, by agreement with the naval governor, 1 stallion, 

 3 mares, and 2 fiUies were transferred to the naval establishment. 

 The transfer relieves the station of the expense of their maintenance 

 and at the same time makes the animals available for breeding and 

 experimental purposes. The breeding and feeding experiments with 

 cattle and swine were continued during the year. The early promise 

 of value of the introduced Para and Paspalum grasses for stock 

 pastures is being mamtained. The breeding and feeding experi- 

 ments with swine are attracting much attention, and the station is 

 unable to keep up with the demand for breeding stock. In a com- 

 parative test a lot of ^rade pigs made average gains of 78.7 pounds, 

 as compared with 37.8 pounds for a lot of native pigs of the same 

 age receiving the same ration. Experiments like this are readily
