nitrate of soda could best be used, and if common salt were a 
useful or necessary adjunct to muriate of potash. The results 
are given in the table on page 274. 
On comparing the plots 1 and 2, and also plots 4 and 5, the 
addition of superphosphate will be found to have given about 
2 tons more in the fii'st case and half a ton more in the second. 
The Norfolk experiments of 1886 and 1887 have consequently 
shown no very decisive advantage from the use of superphosphate 
for mangold, at least on the particular land experimented on. 
The addition of a small quantity of bone-flour to superphosphate 
would not appear to be required, and the joint use of salt and 
muriate of potash was evidently not requisite. Lastly, the 
smaller dressings of nitrate of soda were equally efficacious with 
the larger, but the season may have had much to do with this 
in not effectually washing in these top-dressings. 
Further experiments were carried out at Whitlingham, 
Aylsham, and Flitcham, upon swedes, but the results, owing to 
the dry season, are of very uncertain nature. The report to the 
Norfolk Chamber contains also records of several additional 
experiments (e.g. on pasture, rotation seeds, clover, sainfoin, 
&c.) conducted by the Chamber on their own account, and more 
specially of local interest. 
A meeting of the Special Experiments Committee of the 
Royal Agricultural Society of England was held at 12, Hanover 
Square on March 6, 1888, when delegates from various local 
societies attended, and the reports, of which the foregoing is an 
abstract, were duly presented. In the course of the discussion 
an opinion was expressed, and appeared to meet with general 
approbation, that it would be very desirable in a future year to 
plan one particular experiment to be carried out simultaneously 
in their several districts by the local societies affiliated for this 
purpose with the Royal Agricultural Society.

Experiments on the Continuous Growth of Wheat, 
The experimental plots were prepared for sowing at the beginning 
of October 1886. Mineral manures were sown on October 11, 
and Browick wheat at the rate of 9 pecks per acre was dibbled 
in, October 13-16. The wheat was well up by November 16,
