different mixtures of clovers and grasses, and in a third instance 
with wild red clover alone. 
The two mixtures differed only in the fact that in one of 
these ordinary white clover was included and that in the other 
mixture this was replaced by “ wild ” white clover. 
The actual composition of the seed mixtures used was as 
follows : — 
Perennial rye-grass . 
Cocksfoot . 
Timothy . 
English red clover 
Wild white clover 
Ordinary white clover 
The ordinary white clover cost Is. bd. per lb., tne wild 
white clover 3s. 9 d. per lb., and the costs of the two mixtuies 
per acre were i — 1 (with wild white clover), 34s. bd. ; 2 (with 
ordinary white clover), 25s. bd. 
After removal of the barley crop, both plots with the 
mixtures looked very well. The third plot (wild red clover) 
was not so satisfactory. This latter plot, however, improved 
very much as the season went on. The differences between 
the habit of the “ wild ” varieties and of the ordinary clover 
were clearly shown in the smaller leaf and more creeping 
growth of the wild varieties. The plots were cut on June 16 
and made into hay, the weights as weighed into the stack being

It will be seen that these were excellent crops. The 
season, however, as is well known, was a very favourable one 
for “ seeds.” Between the ordinary white clover and the wild 
white no difference was shown, but the plots will be left for a 
second year, . 
A second crop of hay was obtained in each case, but, owing 
to the plots having been much trampled over by visitois diuing 
the season, a comparison of the second crops was not to be 
relied upon.

The lucerne plots which had been laid down in the spring 
of 1911 and the results of which for 1912 are recorded in last 
year’s report, were kept on. It will be remembered that one- 
half of each plot had been sown bare and the other halt under 
a corn crop (barley), and that in 1912 the plots sown without a
