The requirements of the Victorian Artificial Manures Acts are as fol- 

 low in regard to the analysis of samples of manures submitted each year : — 

 " In the case of manures which are not liable to vary in quality 

 during the current season every vendor of or dealer in 

 manures, who is required by the jNIinister so to do and manu- 

 facturer or importer of manures shall every year in the month 

 of October or Noveml>er and also whenever required b\ the 

 Minister so to do deliver to the said chemist without pay- 

 ment samples not exceeding two pounds in weight of the 

 manures which he intends to offer for sale or which he will 

 use in making any special mixture required and which are 

 not liable to vary in quality during the current season." 

 " The said vendor manufacturer importer or dealer shall forward 

 with such samples a statutory declaration in such form as 

 mav be prescribed to the effect that the samples delivered are 

 correct samples of all the manures to which this section 

 applies which he will offer for sale or sell during the current 

 sea.son and declaring the prices at which he will either him- 

 self or through his agents sell such manures to persons who 

 require the same for purposes of cultivation but he may vary 

 any such price after giving notice of such variation to^ the 

 said chemist." 

 " The said chemist shall analyze or cause to be analyzed under his 

 supervision all samples forwarded to him pursuant to this 

 Act by vendors manufacturers or importers of or dealers in 

 manures, and taking into account the constituents which have 

 a commercial value in each sample, shall calculate from the 

 results of the analysis the average unit value of such con- 

 stituents, and shall then compile a complete list of all the 

 manures offered for sale showing the prices asked for the 

 same and showing also their value according to the average 

 unit values as calculated from the analyses." 

 " Such average unit values shall constitute the basis for calculating 

 the values of all manures for twelve months from the pub- 

 lication of such list pursuant to the provisions of the Artificial 

 Manures Acts."

 analvsis and valuation for the 19 10 season numtered 103, and the analyses 

 of the whole of the samples, their selling price, and their calculated values
