Cocoanut cake, which is largely produced in the manufacture 
of cocoanut oil, rarely passes into the hands of the farmer ; and, 
judging from its presence in mixed linseed-cakes, it is probably 
bought up by oilcake makers and used for adulterating linseed- 
cake. 
With the sanction of the Chemical Committee I instituted, 
as in former years, a number of field experiments on — 1. Root- 
crops : mangolds and swedes ; 2. On potatoes ; 3. On artificial 
grasses ; 4. On permanent pastures. The following printed list 
was forwarded to a number of agriculturists residing in different 
parts of the country, and a larger number of reports have been 
received than in former years. 
Experiments. 
Field Experiments on Boots : Mangolds, Swedes, Turnips, and 
Carrots. — The following experiments are recommended with a 
view of ascertaining what is the best root-manure on different 
soils ; each plot to be one-twentieth of an acre :
