Suggestions to Purchasers of Fertilisers and Feeding Stuffs. 
Purchasers are recommended in all cases to insist on having an INVOICE, and to see that 
such invoice contains the following particulars : — 
In the case of Fertilisers : — 
(1) The name of the Fertiliser. 
(2) Whether the Fertiliser is artificially compounded or not. 
(3) The minimum analysis of the Fertiliser in respect of its principal fertilising 
ingredients. 
In the case of artificially prepared Feeding Stuffs for Cattle : — 
(1) The name of the article. 
(2) The description of the article — whether it has been prepared (a) from one substance 
or seed, or (b) from more than one substance or seed. 
(3) The percentages of oil and albuminoids guaranteed. 
For example : 
(а) An invoice describing an article as “Linseed Cake ” implies a warranty that the 
article is pure, i.e., is prepared from linseed only; “Cotton Cake” (whether 
decorticated or undecorticated), and “Rape Cake” (for feeding purposes), 
would come under a similar category. 
Purchasers are reminded that the use of such terms as “95 per cent.,” “ Oil Cake," &c., 
affords no security against adulteration. The adoption of the Order Form issued 
by the Society is therefore strongly recommended. 
(б) In the case of a Compound Cake or Feeding Stuff, a Vendor is compelled by the 
Fertilisers and Feeding Stuffs Act of 1906 to state the percentages of oil 
and albuminoids guaranteed, and that it is prepared from more than one 
substance, but he is not required to specify the particular materials used 
in its preparation. Purchasers are recommended, therefore, to buy Mixed 
F eeding Cakes, Meals, &c., with a guaranteed analysis. Any statements in 
the invoice as to the component parts of such Mixed Cake or Meal will 
take effect as a warranty, as also will any statements in an invoice, circular, 
or advertisement as to the percentages of nutritive and other ingredients in 
any article sold for use as food for cattle. 
Members of the Society are strongly recommended not only to see that the invoices 
given to them accurately describe the goods they have ordered, but to make all their orders 
subject to the Analysis and Report of the Consulting Chemist of the Royal Agricultural Society of 
England. Copies of a Form of Order (see page v,) for this purpose may be obtained on 
application to the Secretary. 
Attention is particularly directed to the recommendations below as to the qualities of 
I ertilisers and Feeding Stuffs which purchasers should demand.
