Journal of Agriculture. 



[8 Feb., 1908. 



the Journal of the Department of Agriculture from time to time, and 

 should be read bv all users of manures. During the past season 

 (February, 1907, to January, 1908) 174 samples of fertilizers were col- 

 lected and the analyses published. It is quite noteworthy that almost 

 without exception the whole of the samples in this large collection of 

 manures were well up to guarantee, and in many instances were in excess 

 of the percentages of fertilizing constituents guaranteed. This may be 

 regarded as a proof of the honest endeavour of manure vendors in this 

 State to comply, in a straightforward manner, with the requirements of 

 the Artificial INIanures Acts.

Production of Invoice Certificates 



It IS necessary, in order to carry out the Act, for the chemist to 

 occasionallv require purchasers of m.anures to forward copies of the 

 invoice certificates supplied to them for his inspection. It has frequently 

 teen found that purchasers do not retain the invoice certificates in their 

 possession. Every purchaser of manure is required by section 24 of the 

 Act to keep any invoice certificate supplied by the vendor of manure, for 

 failure to produce the invoice certificate when required to do so by the 

 Chemist for Agriculture renders purchasers of manures liable to a penalty 

 not exceeding £,x for the first offence, and not exceeding £,s for any 

 subseauent offence. 



*For 1908 Season i per cent, of Insoluble Phosphoric Acid in a Nitro-super- 

 phosphate is worth is.
