" This cake ought to be cleaner than it is. It is not pure ; was it bought 
as such ? " J. Augustus Voelcker." 
On Mr. Pitts giving the particulars, Dr. Voelcker wrote : — 
" Frederick Pitts, Esq., Oving, Chichester. "April 19, 1888. 
" Cake No. 658. 
" Dear Sir, — I am obliged to you for the form sent and the particulars. 
As you will see, the cake has just upon 4 per cent, of sand, m addition 
to which it has foreign seeds, chiefly rape, in larger quantity than it ought 
to. It certainly is nothing like what a cake would be if made from seed 
really 96 per cent. pure. — Yours faithfully, " J. Augustus Voelcker." 
4. Mr. Robert Tinniswood, of Rose Bank Farm, Carlisle, 
purchased, on Feb. 17, four tons of manure, termed "Special 
Land Fertiliser," at Al. per ton delivered. This was supplied 
to him by the British Farmers' Manure Supply Association, 
21 Collingwood Street, Newcastle-on-Tyne (Head offices, 20 Ab- 
church Lane, London, E.G.). On sending a sample to Dr. 
Voelcker, the following was the report : —

" An extravagant price to pay for such material, which, I should add, 
contains sulphur compounds, which make its application in a fresh state to 
crops very prejudicial. I would not advise you to use it. 
" J. Augustus Voelckek." 
When Mr. Tinniswood sent on the report, the vendors, after 
some correspondence, agreed to take 11. 7s. 6d. a ton. The offer 
was accepted.
