potato tops were also from the station grounds; the taro tops from 

 Pauoa Valley, and the ti leaves, which are considered excellent fodder 

 for horses and cattle, were gathered near Honolulu.

The prickly pear, banana tops, and other miscellaneous forage plants 

 analyzed were in general found to contain small proportions of the 

 different nutritive elements in addition to a large proportion of water. 

 An exception is the kolu (Acacia farnesiana), which contained 23.04 

 per cent nitrogen-free extract, 6.87 per cent protein, and only 60 per 

 cent water. 



ROOTS. 



The only root crop analyzed was cassava. Sample No. 1 of the fol- 

 lowing table was grown on the station grounds and sample No. 2 was 

 obtained from Ahuimanu. The sample from the station grounds was 

 long past maturity and very wateiy in composition, and may be fairly 

 regarded as containing a minimum amount of starch. Cassava, 

 extensively grown in all tropical countries, is very important both as 

 a food and as a feeding stuff. 



The following table shows the composition of the samples of cassava 

 root analyzed:
