368 Annual Report for 1913 of the Consulting Chemist. 
A consisted, as might well be supposed, of cereal grains, 
among which were barley, oats, wheat, maize and millet, 
together with the residue of hops. 
B consisted mainly of rice and earth-nut, with molasses, 
but it had also weed seeds such as chenopodium, polygonum and 
spurrey , together with rape. It was sold on a guarantee of 
containing 7 per cent, of oil and 21 per cent, of albuminoids, 
the cost being 15s. per cwt. ; besides being below the guarantee, 
it was a material that I should consider distinctly dear. 
C was a material for which 4/. a ton on rail in London was 
charged. It will be noted that it contained a great deal of sand 
and earthy matters, and it also had weed seeds in quantity. I 
should consider the material of, at best, small feeding value, 
and not at all a desirable one to use. 
D came from a chocolate factory, and cost 71. per ton. It 
was not a clean sample, the amount of sand being distinctly high, 
and the price, in my opinion, is far more than a waste material 
of this kind should cost. In last year’s report I referred to a 
similar, but better, material, which cost only 3 1. per ton. 
B. Fertilisers. 
In regard to fertilisers generally it may be said that the 
supply has been very satisfactory, and that purchasers have 
had very little to complain about. I am not aware of a single 
case where I have found superphosphate to come below the 
guarantee given, and the quality of basic slag, speaking 
generally, has been good and up to guarantee. The number of 
new materials and of inferior manures sold at a high price has 
been comparatively small. 
1. Basic Slag. 
The following is an instance of a high quality slag : — 
Percentage of : — 
Phosphoric acid 19-93 
equal to tribasic phosphate of lime . . . 43-55 
Phosphoric acid soluble in 2 per cent, solution 
of citric acid 16-06 
equal to tribasic phosphate of lime . . 35*09 
Fineness 94-80 
This was guaranteed to contain 42 per cent, of total 
phosphates with -85 per cent, of “fineness,” the price being 
51s. 6d. per ton delivered. Not only was the material well 
above the guarantee, but it was decidedly cheap. 
2. Compound Manure. 
It still - occurs occasionally that an inferior material sold 
under some name such as the above is put forward and charged 
at an extravagant rate. Such, for instance, is the following : —
