“ A ” had been guaranteed to contain 92 per cent, of lime, with 
only P92 per cent, of silica; and “B” was supposed to be the 
“ best ground lime.” Both, it will be seen, fell much below 
the descriptions given. Indeed, I may say that I can hardly 
call to mind a really first-class sample of ground lime which 
has been sent to me for analysis in the ordinary course. 
6. Refuse Lime. 
Occasionally lime which has been obtained as a waste 
product in some manufacturing process is available for use and 
can be profitably employed. As a rule, the bad condition of 
the lime and the difficulty of applying it to the land form the 
chief bar to its utilisation. In the following instance lime was 
obtained as a residue in soap manufacture, and the water was 
subsequently removed, as far as possible, by hydraulic pressure. 
The result was to obtain the lime in a friable condition and 
capable of ready distribution. In this state it was obtainable 
at the low cost of 2s. per ton at the works. The analysis of 
it was : — 
Moisture ....... 28 v 57 
Oxide of iron and alumina .... ’25 
Lime ....... 4T92 
Siliceous matter. ..... *40 
Carbonic acid, &c. ..... 29 - 86

7. Mustard Cake. 
A sample of mustard refuse cake was sent to me which 
analysed as follows — - 
Moisture . . . . . . . 13-12 
1 Organic matter ...... 82"28 
2 Phosphoric acid . . . . . . ‘66 
Lime ........ 1*29 
Magnesia, Alkalies, &c. .... 2*59 
Sand ........ "06

1 Containing nitrogen ..... 2*87 
Equal to ammonia ..... 3"48 
2 Equal to phosphate of lime . . . 1"44 
This cost 31. 6s. 3d. per ton delivered, rape cake costing on 
the same terms 4 1. 10s. per ton. Considering that the latter
