Artificial Manures Ads.

percentages of plant foods contained in the manures, and the retail price 

 per ton. From the.se percentages and prices, the unit values of the con- 

 stituents, which have a commercial value, are calculated, and this unit 

 value constitutes the basis for calculating the values of all manures for 

 the period during which the registered brands continue in force. 



Another important amendment is the introduction of a schedule fixing- 

 a definite limit of deficiency allowable in all fertilizers. When an)- 

 manure is shown to contain less nitrogen, phosphoric acid, or potash than 

 the proportions stated on the label or in the invoice certificate, to the 

 extent set forth in ^he schedule, the vendor is liable to a fine of ^10 for a 

 first offence, and -Q^o for aiiv subsequent offence.

Amongst the important sections of the old Act which have not been- 

 repealed are Nos. 5 and 7. These clauses require the vendor to attach 

 to each bag a label or tag, declaring the composition of the manure sold 

 in quantities exceeding 56 lbs., and to deliver to all purchasers of manures- 

 at or before the time of sale an invoice certificate conveving similar infor- 

 mation to that required to l>e stated on the label. 



Practical L'tilitv of Unit Value System. 



From the unit values and the guarantee contained on the tags or- 

 invoice certificates, any purchaser of manure is enabled to ascertain if 

 the ])rice asked for a manure is its reasonable commercial value. 



Tt should be borne in iniml that in Iniying a fertilizer at a stated ])rice 

 per Ion (Ik puK haser is buying so many pounds of plant foods according to- 

 guaranlee. ami it dot's not necessarily follow that the manure for which 

 the lowest price per ton i."; asked is the cheapest one to purchase. 



Low grade manures are generally expensive in tin- long run. when the- 

 cost of handling, transport, and other expen.ses are taken into consideration. 

 It will be noted thai thi' \ixur asked for mixed manures is generallv higher 

 than the coinmercial \alne which would Ik* arrived at bv means of a 

 calculation from the unit \alne. but it nuist l)e rememlH-red that in fixing 

 the unit values no allowance i>, made b)r the cost of mixing and other 

 incidental e\i)enses. but only the actual value of the constituents which 

 ii.ni' a (oinmereial \alue is taken into account.
