REPORT OF THE HORTICULTURIST. 



By J. E. HiGGiNs. 



CACAO. 



The work on the growing of cacao at Hilo, mentioned in tlie report 

 for the fiscal Acar 1904, has been begun and is well under way. A 

 tract of 3 acres has been cleared, plowed twice, sul)soiled in part, and 

 prepared for the cacao plants. The field was laid otf in five sections, 

 in which cacao trees of different varieties will be experimented with 

 under diti'erent methods of treatment. The relative advantages of wide 

 and narrow planting is being tested, including an experiment in double 

 planting, with a view to removing half or possiblv three-quarters of 

 the trees as they increase in age and before thev l)ecGme crowded. 



Through the courtesy of Hon. E. W. Gurr, of Tutuila, Samoa, the 

 station has received seeds of several varieties. These were planted in 

 some of the sections of the field and also in nursery row. It is not a 

 common practice to plant this tree in nursery form because of the 

 difficulty of removing it in safety. It is a somewhat current belief 

 that it is ruinous to a cacao tree to injure its tap root, but this should 

 probably not be accepted without qualification. Tests will be made in 

 removing the nursery trees. 



Through the cooperation of the Bureau of Plant Industry, U. S. 

 Department of Agriculture, this station is promised a collection of 

 the more important and promising varieties of cacao from different 

 parts of the Tropics. These plants, when received, will be planted at 

 once in the field at Hilo. 



BANANAS AT HIL.O. 



In connection with the cacao Avork at Hilo, many experiments with 

 bananas are being carried on. The cacao requires shade, and no plant 

 furnishes a better temporary protection than does the })anana. This 

 affords an opportunity to make the land do double duty from an 

 experimental point of view. In the interests of commercial banana
