From the weights given it will be seen that plots 6 and 7 
(mixed mineral manures, including potash, with nitrogenous 
salts) maintained the marked superiority they had shown in pre- 
vious years, and were the only ones to give a really good crop. 
Varieties of Lucerne {Stackyard Field), 
1905 and 1906. 
Considerable difference of opinion existing as to the relative 
values of different varieties of lucerne, a trial was begun in 
1905 with three different sorts, kindly supplied by a member 
of Council. The three sorts were : — (1) Provence seed, the 
kind usually purchased in England, and the dearest sort ; (2) 
American seed, the Alfalfa of South America ; (3) a Canadian 
variety. The seed was drilled in on June 15, 1905, no manure 
being used. No cutting was obtained in 1905, but in 1906 
three cuttings were taken, viz., on June 20, August 17, and 
November 6. From the beginning the Canadian variety looked 
the best, then the American. The weights are given in Table 
XVIII.

Varieties of Clover {Lansome Field), 1906. 
Mr. Carruthers, the Society’s Consulting Botanist, having 
obtained parcels of clover seed from reliable sources in Canada, 
America, and elsewhere, it was decided to make a trial of 
these at the Woburn Farm, in regard to their cropping power 
and duration of growth. Plots were, accordingly, laid out in 
Lansome Field, sown with a barley crop, and the clover seed 
drilled in between the rows on May 11, 1905, at the rate of 
21 lb. per acre. The different varieties were : — 
Plot 1. Chilian red clover 
,, 2. Canadian red clover. 
,, 3. Canadian mammoth red clover. 
,, 4. English red clover. 
„ 5. English late-flowering red (or cow-grass) clover. 
„ 6. Canadian red clover (old seed). 
,, 7. Canadian mammoth red clover (old seed). 
,, 8. Silesian red clover. 
It had been intended to start this experiment in 1904, and 
the seed used on plots 6 and 7 was kept over from then. 
A very good plant of clover was obtained, and stood the
