No. 2 was a good linseed-cake. The cake marked No. 1, it 
will be seen, was poor in oil, and made from dirty linseed. 
Mr. Martin wrote on the 14th of January, 1881 : — 
" I am very much surprised at the analysis of No. 1 linseed-cake, which 
was bought as pure, and from a firm professing a great deal of purity. The 
price was 9Z. 12s. did. in Hull, making it \0l. 2s. Qd. at my station ; No. 2 
price at my station would he 9Z. 17s. M. I mean to claim 20s. per ton com- 
pensation on No. 1 cake." 
This claim was eventually paid, and Mr. Martin declined to 
give the name of the vendor. 
3. A sample of artificial manure manufactured in Jersey, and 
said to contain blood, bone, guano, &c., was sent for analysis 
by Mr. VV. M. Jones, Guernsey. The manure had the following 
composition : — 
Moisture 25*40 
* Organic matter 21 '60 
Phosphate of lime 8*25 
Carbonate of lime 11 "01 
Oxide of iron and alumina, iSrc 4*94 
Insoluble siliceous matter (sand) 28 '80 
100-00 
Containing nitrogen 1-80 
Equal tu ammonia 2-19 
This manure was sold as " Engrais artificiel " (artificial 
manure) at 11. 10s. in Jersey, or 8/. per ton delivered in 
Guernsey. 
The maker asserted that the manure was as rich as Peruvian 
guanO; and more concentrated than in previous years.
