438 EXPERIMENT STATION EECOED. 



a uiirsery of citrus stock to provide material for budding and grafting, and a 

 few acres of coffee and rubber trees. Two hundred cuttings of vanilla placed in 

 a grove of Keawe have rooted nicely and are expected to bear in a j^ear or more. 

 An extensive cooperative experiment with wine grapes is being conducted on 

 the island of Maui, iu which 177 varieties are being tested. 



lielative to coffee, it is stated that the chief cause of failure in Hawaii is due 

 to economic conditions, as there are no difficulties about growing the crop. 

 While the best grades have always been in demand the low grades can not be 

 produced in competition with Brazil and similar countries, which tends to force 

 the small producer out of business. 



The cooperative experiments with cacao and bananas have been continued on 

 the grounds of the Hilo boarding school. The growth of the cacao during the 

 past year is reported as unfavorable, principally due to an unusual drought in 

 a region which usually has abundant raui. Bananas planted for shade have 

 grown well and some varieties have fruited. 



Results of marketing experiments with liorticultural crops have been i)re- 

 viously noted ( E. 8. R.. 10, p. 33.S). 



Report of the horticulturist, J. E. Higgins {Hawaii t>tn. Rpt. 1906, pp. 33- 

 36). — Brief notes are given on the present status of citrus fruits and mangoes 

 in Hawaii, together with some data on the distribution of Bluefields banana, 

 roselle culture, and a partial list of plant accessions made during the year end- 

 ing June 30, 1906. 



Several varieties of lemons, together with superior limes and seedling pomelos 

 are reported as growing in the gai-dens of Honolulu and other parts of Hawaii. 

 An orange has recently been noted which has a decided tendency toward the 

 navel type and lacks nothing in flavor. It is believed that by multiplying some 

 of the native seedling oranges the fruit can be produced almost the whole year 

 iu most localities. A bulletin dealing with the culturevtf citrus fruits in Hawaii 

 was published in the early part of the year and previously noted (E. S. R., 17, 

 p. 767). 



As has been previously noted in a bulletin on the mango in Hawaii (E. S. R., 

 17, p. 1155), the presence of the mango weevil (Cryptorhynchus tnangiferce) is 

 said to be the one serious hindrance to the progress of the industry. A plea 

 is made for more stringent measures to control and destroy this insect. A col- 

 lection is being made of the tinest varieties of mango trees available, and these 

 will be propagated on seedling stock. 



Experiments conducted witli the roselle show the plant to be well adapted to 

 local conditions. The yield of fruit per acre under average conditions is given 

 as from 6,0(X) to 7,000 lbs. The fleshy calyx and the seed pod while young and 

 tender are said to make an excellent jam and jelly. While fairly tolerant of 

 dry weather, it is stated that the plant improves and produces more heavily 

 with irrigation. The seed is sown about March, and the plants set in the field 

 when from 6 to S in. high. IManting distances recommended are 4 by 6 ft., where 

 either irrigation is to be employed or rainfall is abundant, and about 4 by 4 

 ft. in dry localities. 



Cantaloupes, P. K. Blinn {Colorado Sta. Bui. 121, pp. 6-8, figs. 3). — The 

 author has succeeded iu developing a cantaloupe with rust-resisting qualities. 

 Seeds were distributed to various sections iu the United States, and brief ex- 

 tracts are given from the reports thus far received. 



In the majority of cases this melon has given good satisfaction and the fruit 

 and vines have held up long after other varieties were attacked by the rust. 

 A record is also given of the author's trials with this seed during the past sea- 

 son, from which it appears that the rust-resistant selection remained green until 

 the majority of the fields were dead. Some of the most markedly resistant
