Judging from these figures, we find that hagi hay has 
very nearly the same composition as hay of lucerne, which 
according to E. von Wolff contains : moisture 16.0%, crude 
protein 14.4%, crude fat 2.5%, crude fibre 33.0%, nitrogen- 
free extract and ash 6.2%. The green fodder from hagi too 
does not greatly differ from green lucerne, the former con¬ 
taining 75.1, the latter when cut at the beginning of blossoming 
74.0% of moisture. 
It was our intention to continue these researches as long as 
possible on the same land in order to determine how long a 
satisfactory yield of fodder can be obtained, but owing to changes 
in the college the plot was needed for other purposes and we 
had to commence the trials afresh in another part of the farm. 
Accordingly, in the spring of 1888 an area of about 300. square 
metres was planted with hagi roots partly taken from our 
former experimental field, partly from the uncultivated land 
round our farm. In the following winter the stems were again 
cut at a height of about 4 centimetres above the ground, and 
in the two subsequent seasons (1889 and 1890) three cuttings 
were taken every summer. In the spring of 1890 a late frost 
destroyed many of the young shoots, but in their place new ones 
sprang up a little later. The injury had, however, no serious 
consequences, and merely retarded the time of cutting for about 
3 weeks. In the winter of last season the field was supplied 
with about 100 kilograms of slaked lime per tan , which was 
harrowed in during fine weather. 
The produce of green fodder and hay was as follows, kilo¬ 
grams per tan :
