Report on the Experiments with Clovers at Wohurn. 253 
phate, 4 cwt. of sulphate of potash, and 2 cwt. of nitrate of soda. 
The manures were sown in the Stackjard-field on the 28th of 
March, 1883, the 19th of iMarch, 1884, and on the 26th of 
March, 1885. In the Warren-field, they were sown on the 
31st of March, 1883, the 22nd of April, 1884, and on the 3rci 
of April, 1885. 
The various plots were thoroughly weeded. 
The crops for 1883 and 1885 were weighed. No record was 
kept of the crops of 1884. 
With the view of seeing whether the life of the clovers was 
affected by permitting the plants to go to seed, one-half of each 
plant was mown just as the clover came into flower. The other 
half was cut when it was in full seed, and the crop was carefully 
removed so as to prevent, if ]possibIe, any of the seeds being 
shed on the plot. This treatment was further intended to repre- 
sent, as far as it could be done in such small plots, the different 
effects of grazing and haying the clovers. 
The first point for investigation was the longevity of the 
various clovers ; the bearing of the experiments on this poinc 
will be apparent when the crops of the two years are compared.

This table shows that the perennial red clover had practi- 
cally disappeared in 1885. The produce of the seven plots in 
1883 amounted to 13 cwt. 1 qr. 6i lbs., while that of 1885 was 
only 1 cwt. 1 qr. 27 J lbs. I examined the plots on the 28th of 
September, 1885, and found that their state then confirmed the 
results of the cropping. The plot with most plants in both fields 
was that which was manured with sulphate of potash. In all 
the other plots the clovers had almost, or altogether, disap- 
peared.
