material and a large proportion of water. The ki, however, dif- 

 fered in this respect, the water being fairly low and the propor- 

 tion of nutritive material fairly high. 



Cactus, or prickly pear, banana tops and butts, sweet potato 

 tops, ti leaves, kiawe beans and root crops were also analyzed, be- 

 sides many commercial products. A fact of special significance 

 shown by the experiments shows that Hawaiian feeding stuffs, 

 especially grasses are, as a rule, deficient in lime, which food con- 

 stituent, should be supplied by leguminous plants or other means. 



"Hals suggests that a deficiency in lime may be remedied by 

 adding suitable mineral matter to the ration, precipated dibastic 

 calcium phosphate being considered superior for the purpose to 

 bone meal, bone ash, or similar very indigestible materials." 



The Infliiencc of Stripping on the Fields of Cane Sugar, by C. 

 F Eckart. Bulletin No. i6, Division of Agriculture and Chemistry, 

 Hawaiian Sugar Planters' Association. Under the above head- 

 ing Mr. C. F. Eckart presents the data obtained by a series of 

 painstaking tests conducted at the Experiment Station, which go 

 to show that under certain conditions much sugar is annually lost 

 by plantations practicing stripping, although stress is laid upon 

 the fact that the question is a local one and that in order to 

 demonstrate the practical utility of the investigations careful field 

 tests must be first made upon the various plantations. As intro- 

 duction to his subject, Mr. Eckart writes: 



"Probably no subject relating to the field operation of the sugar 

 industry in these islands has been more freely discussed by 

 plantation managers than that of stripping, or the removal of 

 dried leaves from the cane stalk. Widely divergent opinions 

 are held as to the economy of this expensive practice, and owing 

 to the radically dift'erent conditions under which cane is grown in 

 this country, it is natural that the experience of some planta- 

 tions, in this particular, has not always been in conformance with 

 that of others. The question is largely a local one and the 

 profits or losses from stripping are determined by the conditions 

 under which the operation is performed. These controlling fac- 

 tors have, in recent years, become so involved througlh the 

 ravages wrought by the leaf hopper pest and fungus diseases that 

 the most careful judgment is now required to determine whether 

 or not the practice may be employed to advantage in any given 

 instance."
