HAGI AS A FORAGE CROP. 
In order to get a more digestible fodder from hagi it will be 
advisable to take the first and second cuttings earlier than we 
did, because it appears that the formation of woody fibre pro¬ 
ceeds very rapidly just before the buds make their appearance. 
By early curing the yield of hay in the first two cuttings will, 
of course, be somewhat lower than in our trials, but this diminu¬ 
tion will be compensated by the better quality and digestibility 
of, as well as by a larger yield in, the third cutting. As we 
intend to continue our researches on this plant, we will pay due 
attention to these conditions. 
The hay of hagi as compared with that of other leguminous 
forage crops contained according to the above feeding experi¬ 
ments the following proportions of digestible nutrients, per cent 
of the air-dry matter:

The low digestibility of hagi hay is accordingly entirely com¬ 
pensated by its richness, so that from a practical point of view 
its nutritive value is equal to that of medium good lucerne hay 
and nearly as good as soy bean hay ( karimame ) cured when the 
pods have completely developed, while it is distinctly superior 
to that of medium good clover hay. 
A calculation of the annual yield of digestible matter per tan, 
based on the preceding figures, gives the following results :
