Further experiments carried out at Bolwick in 1890 on another 
field, again sliowed a gain from the use of superphosphate for the 
mangel crop. The Bolwick soil, however, as noticed in other ex- 
periments, appears to be deficient in phosphates, and the question is 
still open whether the beneficial effect of superphosphate shown here 
would be found in other parts of Norfolk, The earlier experiments 
of the Chamber pointed to the reverse. 
Salt Experiments upon Barlerj. 
These experiments were tried in 1890 at Bolwick and at 
Whitlingham ; the land had in each case been half- folded with sheep. 
The results were : —

These results point to no definite conclusion. At Bolwick the 
corn was much more laid on the salt plot than on that without salt. 
At Whitlingham rather more produce came from the salt plot, and 
neither crop was laid much. 
Experiments on permanent grass-land, begun some seasons past, 
continued to show in 1889 and 1890 annual deterioration from con- 
tinuous mowing, and the uselessness of artificial manures to prevent 
this. Farmyard manure and folding of sheep gave decidedly the 
more satisfactory results. 
The Report of the Norfolk Chamber contains the record of 
several other field experiments carried out during the two years, 
and, in addition, that of the sheep-feeding experiments, which are 
of much utility, and are therein set out in full detail.

May 5, 1891. 
Since my report of March 3 (page 168) the usual amount of ap- 
plication has been made regarding farm insect pests, but far more 
than has ever occurred before respecting various kinds of insects 
seriously injurious in fruit growing. About 400 applications for my 
Paris Green pamphlet have been received, and as in many cases a
